INTERFAZ DE USUARIO
KOReader tiene una interfaz de usuario sencilla, principalmente en blanco y negro, porque los degradados y los diferentes tonos de gris pueden provocar parpadeos y efecto fantasma en las pantallas de tinta electrónica, lo que puede degradar la experiencia de lectura.
KOReader tiene dos interfaces principales: la PANTALLA DE LECTURA y el NAVEGADOR DE ARCHIVOS.
Pantalla de lectura
La PANTALLA DE LECTURA tiene dos barras de herramientas. El MENÚ SUPERIOR incluye elementos relacionados al uso general de KOReader. Aquí accederá a los libros, las preferencias de KOReader, los complementos y más. El MENÚ INFERIOR se enfoca en opciones de formato del documento tales como el tamaño y el grosor de la letra y el espaciado de los renglones. Al ajustar la apariencia del texto, interactuará con más frecuencia con el MENÚ INFERIOR.
A la derecha puedes ver las zonas de toque predeterminadas de KOReader. Para mostrar el MENÚ SUPERIOR o el MENÚ INFERIOR puedes tocar las zonas indicadas. También puedes deslizar hacia abajo la zona superior para mostrar el MENÚ SUPERIOR. En dispositivos no táctiles como Kindle 4, puede abrir el MENÚ INFERIOR presionando el botón que corresponde a la acción ENTER/OK.
Puede configurar la zona MENÚ SUPERIOR para abrir tanto el SUPERIOR como el MENÚ INFERIOR al mismo tiempo a través de este menú:
⇑ MENÚ SUPERIOR → → Toques y gestos → Activar menú
Las ZONAS DE TOQUE EN LAS ESQUINAS se pueden usar para muchos tipos diferentes de gestos, incluidos TOCAR, TOCAR DOBLE, TOCAR CON DOS DEDOS y TOCAR y MANTENER PULSADO.
Las zonas PÁGINA ANTERIOR y PÁGINA SIGUIENTE también se pueden utilizar para gestos de DOBLE TOQUE al mismo tiempo.
Se puede tocar la BARRA DE ESTADO para alternar entre los elementos de la BARRA DE ESTADO si solo hay un elemento visible. Si todos los elementos están visibles, al tocar se mostrará y ocultará la BARRA DE ESTADO. Consulta el encabezado “¿Cómo puedo configurar la barra de estado?” para obtener más información.
Navegador de archivos
Verá el NAVEGADOR DE ARCHIVOS la primera vez que ejecute KOReader. Puede acceder a este desde la pantalla de lectura si sigue estos pasos:
⇑ MENÚ SUPERIOR →
De forma predeterminada, NAVEGADOR DE ARCHIVOS muestra su INICIO, que es la carpeta principal de su biblioteca, que puede cambiar tocando y manteniendo presionado. cualquier carpeta. Puede cambiar sus numerosas opciones, como cómo se muestran u ordenan los libros, a través del MENÚ SUPERIOR deslizándose hacia abajo desde la parte superior de la pantalla.
A continuación se explican los elementos encerrados en círculos en la imagen:
RESTABLECER: Esta opción le permite restablecer algunas propiedades de su documento como progreso de lectura, marcadores, imagen de portada personalizada, etc., que puede elegir a continuación diálogo.
ADVERTENCIA Ten mucho cuidado al usar este cuadro de diálogo y verifique qué elementos están marcados; de lo contrario, puede restablecer todo accidentalmente.
ABRIR CON: KOReader tiene diferentes motores para renderizar diferentes tipos de archivos. En algunos casos, puedes abrir un archivo en un motor diferente para obtener otras funciones. Consulta las secciones Ver archivos comprimidos y Ver archivos de imágenes justo debajo.
IGNORAR PORTADA: Si por alguna razón desea desactivar la portada de este libro (puede tener una portada incorrecta o la portada no es muy legible en la pantalla de tinta electrónica), puede seleccionar este.
IGNORAR METADATOS: si los metadatos de su libro no son correctos, el campo Nombre podría mostrar información irrelevante. Seleccione esta opción para mostrar el nombre del archivo en lugar de los metadatos.
ACTUALIZAR LA INFORMACIÓN DEL LIBRO EN CACHÉ: KOReader almacena en caché los metadatos y la portada de un libro cuando lo agregas a la biblioteca. Si realizas algunos cambios en el libro después de copiarlo a tu dispositivo, es posible que sea necesario actualizar esta información. Si ves una portada o metadatos incorrectos, puedes actualizar la información del libro con este elemento del menú.
Visualizar archivadores
Es posible abrir archivos ZIP, CBZ y EPUB (que también son archivadores ZIP) con el visor de archivadores para consultar los archivos que contienen:
En el Explorador de archivos, mantén presionado el nombre del archivo
Toque Abrir con…
Toque Visor de archivadores
Visualizar imágenes
Puedes abrir archivos de imagen con el visor de imágenes en lugar de abrirlos como un libro. Los archivos abiertos de esta manera no aparecen en tu historial y tienen un mejor escalado y soporte de rotación.
En el Explorador de archivos, mantén presionado el nombre del archivo
Toque Abrir con…
Toque Visor de imágenes
Configuración de asociaciones de archivos
También puedes establecer asociaciones de archivos para tipos de archivos que KOReader no reconoce automáticamente. Para asociar un archivo con uno de los proveedores de KOReader, primero toca prolongadamente tu archivo en el navegador Archivo y luego elige un motor de proveedor para manejar este archivo. Puedes comprobar:
Utilizar siempre este motor para este archivo para asociar este proveedor únicamente con este archivo en particular
O marca Usar siempre este motor para el tipo de archivo para asociar este proveedor con todos los archivos que tengan la misma extensión que éste. Desde el mismo cuadro de diálogo, puedes ver las asociaciones que has realizado pulsando sobre Ver valores predeterminados para los tipos de archivo.
Acceder a sus libros
Existen estos métodos para acceder sus libros y artículos:
Navegador de archivos: como se ha explicado anteriormente
Favoritos: una lista en la que puede añadir libros si toca prolongadamente sobre ellos en el navegador de archivos
Historial: lista de libros que ha abierto
Puede cambiar el aspecto de estas pantallas desde:
⇑ MENÚ SUPERIOR (en el explorador de archivos) → → Modo de visualización
Si desea cambiar cuántos elementos están visibles en estas pantallas, mire aquí:
⇑ MENÚ SUPERIOR (en el Navegador de archivos) → → Ajustes → Ajustes de mosaico y lista detallada
Puedes asignar gestos para cada uno de estos diálogos. Por ejemplo, mientras lees un libro, puedes acceder a tu Historial o Favoritos con un gesto y abrir otro libro sin tener que pasar por el Navegador de archivos.
Puedes buscar un libro en Historial por nombre de archivo o metadatos del libro desde el botón del menú de hamburguesa superior izquierdo.
También puedes configurar KOReader para que comience con Favoritos o Historial de la pantalla en lugar de Explorador de archivos mediante:
⇑ MENÚ SUPERIOR (en el Navegador de archivos) → → Empezar con
Atajos a carpetas
KOReader le permite añadir sus carpetas favoritas a un menú de atajos de rápido acceso. Por ejemplo, si tiene en su biblioteca una carpeta Archivados organizada en una jerarquía Inicio > Artículos > Científicos > Archivados, puede asignar un atajo a esta carpeta Archivados y acceder a ella rápidamente incluso si está leyendo un libro.
Añadir un atajo a una carpeta
Existen dos maneras de añadir una carpeta a su lista Atajos a carpetas:
Cuando esté en el navegador de archivos, pulse el botón + (más) en el menú superior, después, pulse la opción de Añadir un atajo a una carpeta e ingrese un nombre descriptivo para este atajo. Esto agregará la carpeta en la que se encuentre actualmente.
Cuando te encuentras en el explorador de archivos, mantén pulsado el nombre de una carpeta para abrir el menú contextual. Pulsa la opción Añadir a accesos directos de carpeta e introduce un nombre descriptivo para este acceso directo. Esto añadirá la carpeta que pulsaste.
Las carpetas que se encuentran en la lista de accesos directos de carpeta tendrán una estrella (★) en el explorador de archivos.
Puedes eliminar una carpeta de los accesos directos de la misma manera, manteniéndola pulsada y seleccionando Eliminar de los accesos directos de carpeta.
Ver sus atajos a carpetas
Es posible abrir sus atajos a carpetas desde el navegador de archivos o la pantalla de lectura mientras lee un libro.
Desde el explorador de archivos: Esquina superior derecha menú + (más) y después seleccionando accesos directos de carpeta o asignando un gesto.
Desde la pantalla de lectura: asígnele un gesto.
Se encuentra bajo la sección Explorador de archivos del Gestor de gestos. Puedes aprender a establecer gestos en la sección correspondiente de esta guía.
Consejos para la interfaz de usuario
INFO La interfaz de usuario y las opciones de KOReaderand pueden cambiar dependiendo del tipo de archivo que abra. Hay dos categorías: Documentos de disposición fija (PDF, DJVU, archivos de imagen...) y Documentos ajustables (EPUB, HTML, DOCX, RTF, TXT…).
Puede cambiar el idioma de la interfaz a través de:
⇑ MENÚ SUPERIOR → → Idioma
Si pulsas y mantienes una opción o un elemento del menú (peso de fuente, interlineado, etc.), puedes establecer sus valores como PREDETERMINADOS. El nuevo valor solo se aplicará a los libros abiertos de ahora en adelante. Los libros abiertos anteriormente mantendrán sus ajustes. Puedes identificar los valores predeterminados con una estrella (★) en el menú o con un borde negro alrededor de los indicadores como se muestra a continuación:
En el MENÚ INFERIOR, si pulsas y mantienes el nombre de una opción, verás su explicación.
Se pueden CERRAR los diálogos que abarcan la pantalla entera (Historial, Sumario, Marcapáginas, Estadísticas de lectura, etc.) deslizando hacia abajo.
Puedes tomar una captura de pantalla deslizando una diagonal larga con tu dedo. También se tomará una captura tocando las esquinas diagonales opuestas. Puedes utilizar este segundo atajo cuando veas una imagen, por ejemplo.
En los cuadros de diálogo que contienen botones de flechas de ajuste como el anterior, puedes pulsar y mantener en los botones de flecha para cambiar el valor en incrementos mayores.
Puede CERRAR este tipo de cuadros de diálogo (no de pantalla completa) tocando una zona fuera de su ventana.
Es posible MOVER estos diálogos manteniendo presionado el título y arrastrándolo.
Puedes hacer que este tipo de cuadro de diálogo sea SEMI-TRANSPARENTE pulsando y manteniendo el título de la ventana (cuando quieras ver el texto de debajo mientras ajustas un valor).
KOReader admite búsquedas en diccionario en los documentos EPUB y PDF/DJVU escaneados. Para ver la definición del diccionario o la traducción, pulsa y mantén pulsada una palabra.
Al mantener presionada una palabra, aparece un cuadro de diálogo en el que también puede buscar más ocurrencias en la selección del documento o buscarlas en Wikipedia.
Si quieres cambiar el tamaño de la interfaz de usuario, hay un ajuste de DPI para ello:
⇑ MENÚ SUPERIOR → → Pantalla → DPI de Pantalla
You can choose a value from the menu or select CUSTOM DPI to enter a value for fine tuning: Higher DPI = Bigger Interface
Note that there is also a Zoom (dpi) setting in the bottom bar. That one is related to the documents only. You can find the explanation in the next section.
Puede deshabilitar el parpadeo negro (actualización parcial automática para eliminar imágenes fantasma) de la interfaz de usuario si le molesta:
⇑ MENÚ SUPERIOR → → Pantalla → Ajustes de tinta electrónica
Si quieres comprobar la fecha actual puedes pulsar en el reloj en el MENÚ SUPERIOR.
Búsqueda de menú
KOReader has lots of features so its menu system reflects this complexity. We have a Menu Search feature for finding menu items quickly. You can access it from:
⇑ MENÚ SUPERIOR → → Ayuda → Menú de búsqueda
También puedes asignar esta función a un gesto o añadirla a tu Menú Rápido para acceder con mayor rapidez.
Tipos de desplazamiento
KOReader incluye tres modalidades de desplazamiento táctil. Puede acceder a ellos mediante:
⇑ MENÚ SUPERIOR → → Toques y gestos → Desplazamiento
INFO Tienes que activar el Modo continuo desde el Menú inferior para poder utilizar el desplazamiento.
Desplazamiento clásico: este modo funciona exactamente igual que el desplazamiento en un teléfono o tableta.
Turbodesplazamiento: este modo le permite desplazarse más rápidamente que con el desplazamiento clásico. Además, le permite pasar páginas sin tener que levantar el dedo. La cantidad de desplazamiento es proporcional a la distancia que mueva el dedo tras iniciar el desplazamiento.
On-release scrolling: This scrolling type is more suitable for e-ink screens. Because unlike other scrolling types, this mode doesn’t refresh your page continuously while scrolling. It works like classic scrolling but intermediate steps are not shown. So you scroll with your finger and when you release, page jumps to that position. This is especially useful to reposition and adjust the view if your book contains pictures or tables and you want to see all of it.
Volver a posición anterior
This useful feature works like the Back button in your browser. When you jump to some other part of the book using Skim widget, Bookmarks list, Book map etc. KOReader remembers your previous location. This is useful for example if you follow an internal link or reference. With one tap you can go back to where you come from. You can access this feature from:
⇑ MENÚ SUPERIOR → → Volver a la ubicación anterior
Also you can go forward too, from the same menu. This feature is assigned to ← → multiswipe gesture. You can assign this to another gesture if you want (like tapping a corner) or add it to your Quick Menu.
Evitar el parpadeo en páginas con imágenes
KOReader normally perform a full refresh on pages containing images (which you can observe as a black flash). The reason is to get rid of the residue and ghosting from the previous page. But this might not be necessary depending on your device and personal preferences. You can disable this auto-refresh behavior here:
⇑ TOP MENU → → Screen → E-ink Settings → Full refresh rate → Always flash on pages with images
Compatibilidad de representación parcial
With the version 2023.03, KOReader gained partial rendering capability while reading EPUB documents. Before this version, when you made an adjustment like changing font size, the whole book had to be rendered again to be able to preview the new setting. Depending on the device and book size, this can take a while to calculate.
Gracias a esta nueva prestación, cuando lea documentos EPUB, los ajustes al aspecto del texto se realizarán mucho más rápido, al representar únicamente el capítulo actual.
INFO This is only possible if your EPUB is composed of multiple fragments. EPUB files are basically .zip archives that contain .html files. Some books can be a single .html file while others may be composed of multiple .html files like each chapter of the book is a separate .html file. If your book is only a single .html file, partial rendering can not work, because for each change KOReader still has to calculate the whole book.
También cambiar la orientación de tu pantalla es mucho más rápido gracias a esta función. Esta función está ACTIVADA por defecto. Si es necesario, se puede desactivar por libro (con una pulsación), o globalmente (con una pulsación larga) en:
⇑ MENÚ SUPERIOR → → Documento → Activar renderizado parcial
After these partial renderings, KOReader and the book enter a degraded state: You can turn pages but some info and features may be broken or disabled (i.e. footer info, ToC, statistics…). To get back to a normal working state, KOReader has to render the rest of the book too. While this is happening, an icon at the top left corner of the screen indicates the status:
Document is partially rendered. Page count, footer info and many things are innacurate. You can see how the new settings look and adjust further. You can also turn pages, jump links in this state.
A full rendering is happening in the background. You can still turn pages, jump links, change settings.
Full rendering is done, but not yet applied because KOReader is waiting for you to be idle to reload the rest of the book (idle=not interacting with the device). You can still turn pages, jump links, change settings.
You've been idle for a while so KOReader is now reloading the whole document. At this step KOReader is blocked to prevent interaction.
When these icons are all gone, you are again in a fully working state. Generally this whole process is quick and as a user you don’t need to do anything extra. You can just adjust your settings and continue reading your book, KOReader will do the rest.
Explicados los Elementos del Menú Inferior
CONSEJO Puedes ver una explicación de estos elementos cuando mantienes pulsados sus nombres en el menú inferior.
VIEW MODE: If you change to CONTINUOUS mode you can scroll the document like a web page. This mode is more suitable for non e-ink screen types (LCD, OLED). In continuous mode you lose TOP and BOTTOM MARGINS so text may be cut on first and last line of screen. To solve this problem you can enable PAGE OVERLAP:
⇑ TOP MENU → → Page Overlap
RENDER MODE: This option determines how your document is rendered by KOReader. Default is WEB and generally you don’t need to change this setting. When a book (or saved web page) is very complicated (specified widths or margins, negative margins, floats etc.) and layout looks bad or overflow the screen, you can try other rendering modes.
ZOOM (dpi): This setting can be thought of as a general zoom factor for the document (except font size). At 96 dpi (which is the default setting), images in the document are rendered at their original dimensions. Basically you will use this setting if you want to make images bigger without making the text bigger.
WORD SPACING and WORD EXPANSION: These two settings are related and they determine how your text will look when it is justified. When you justify text, space is added between words so that both edges of each line are aligned with both margins. Since word counts of lines are not equal all the time, in justified alignment, text has to be compressed or expanded to fill the line.
WORD SPACING: How much the SPACE characters in a line of text can be compressed to fit more words. This setting doesn’t affect words, it only changes the space between them.
WORD EXPANSION: If you have too much white space in a line, how much of that can be distributed into the words by expanding them. This setting affects the appearance of words. If you don’t want your words to expand, set this to NONE.
Puede experimentar con las distintas configuraciones hasta que el texto se vea agradable a su juicio y establecerlas como predeterminadas en sus diálogos respectivos.
CONTRAST and FONT WEIGHT are two options that you can use to make your text bolder (or lighter). You can achieve the same appearance with either of these options but they use different methods to achieve it. Of course you can use them both at the same time. The differences between them can be summarized as:
CONTRASTE
+ No cambia la anchura de la letra; la longitud del libro permanece igual
+ No hace falta volver a representar el documento; es más veloz
- Puede verse mal en pantallas LCD o de baja densidad de píxeles
PESO DE LETRA
+ Utilizará los grosores de letra adecuados si los ha instalado
+ Se ve mejor en pantallas LCD o de baja densidad de píxeles
- Hay que volver a representar los tipos de letra, lo que es más lento
FONT HINTING adjusts your text for maximum readability according to your screen’s pixel grid. NATIVE uses font’s internal hinting instructions, AUTO uses FreeType’s hinting algorithm. AUTO is a safer choice because font files that you installed may have problematic hinting instructions. Also AUTO handles CJK text better. You can try different settings to see which one looks better on your device.
FONT KERNING adjusts the spacing between letters to achieve a visually pleasing result. Default is BEST, which might be slower when opening files (depending on your device) but has better support for ligatures (see picture below for an example), joined Arabic glyphs and some other scripts. If your device is slow, you can try GOOD which is faster and may still look correct with western latin-script text.
BARRA DE ESTADO ALTERNATIVA activa una barra de estado alternativa que está disponible solo en los documentos ajustables (EPUB, HTML, DOCX, RTF, TXT…). Tras activarla aquí, puedes configurar la BARRA DE ESTADO ALTERNATIVA a través de:
⇑ MENÚ SUPERIOR → → Barra de estado → Barra de estado alternativa
EMBEDDED STYLE and EMBEDDED FONTS determine if publisher’s styles and fonts embedded in the document will be used (or ignored) to render the document. These are general on/off switches. You can achieve more fine tuned tweaks for your document via:
⇑ MENÚ SUPERIOR → → Retoques de estilo
El ESCALADO DE IMÁGENES determina cómo se representan las imágenes del documento. MEJOR se ve más agradable pero es más lento.
Saving your text appearance settings for later use
This powerful feature allows you to save all the BOTTOM MENU settings + font type as a profile. This means you can have different group of settings for different conditions or book types which you can apply at once instead of changing the settings manually every time. For example you can create a:
El perfil de Columna doble con dos columnas de texto pequeño, orientación horizontal y márgenes mínimos
Night reading profile with bigger sans serif font and higher contrast for more visible text under low light
Disabled styles profile with embedded style and embedded fonts disabled for badly structured books
Luego de ajustar la configuración a su gusto, puede crear un perfil a través de:
⇑ MENÚ SUPERIOR → → Perfiles → Nuevo con los ajustes de documento actuales
Tras crear un perfil con tus ajustes, tienes muchas opciones de aplicarlo en otro libro:
Puedes aplicar un perfil desde el Menú de perfiles
Invertir los colores en pantalla (blanco sobre negro)
⇑ MENÚ SUPERIOR → → Modo nocturno
Cambiar muchas otras opciones de formato
⇑ MENÚ SUPERIOR → → Retoques de estilo
INFO *Font selection and style tweaks are available only on reflowable documents (EPUB, HTML, DOCX, RTF, TXT…). Fixed-layout documents like PDF/DJVU are not supported.
You can also change other formatting options from the BOTTOM MENU to fine tune the appearance of your text.
Puedes ver tus estadísticas de lectura a través de:
⇑ MENÚ SUPERIOR → → Estadísticas de lectura
How can I control the backlight / frontlight of my screen ?

⇑ TOP MENU → → Frontlight
¿Cómo se configura la barra de estado?
Puedes configurar la barra de estado inferior desde este menú. No dudes en explorar el submenú de AJUSTES para personalizar tu barra de estado a tu gusto.
⇑ MENÚ SUPERIOR → → Barra de estado
Hay muchos elementos que puedes mostrar en la barra de estado. Pero por defecto, solo se muestra uno cada vez y tienes que pulsar en la barra de estado para pasar de uno a otro. Si quieres mostrarlos todos a la vez, activa este elemento del menú:
⇑ MENÚ SUPERIOR → → Barra de estado → Ajustes → Mostrar todo a la vez
Es posible ordenar los elementos mediante:
⇑ MENÚ SUPERIOR → → Barra de estado → Ajustes → Ordenar elementos
Puedes alternar la visibilidad de la barra de estado con un gesto o a través del Menú rápido:
Gesture selection menu → Reader → Toggle status bar
También hay una BARRA DE ESTADO ALTERNATIVA que está disponible en los documentos ajustables (epub, html, docx, rtf, txt…). Si prefieres utilizar esto, puedes activarlo a través de:
⇓ MENÚ INFERIOR → → Barra de estado alternativa
Uso del elemento "Texto personalizado" para la alineación de la barra de estado
Hay un elemento especial de la barra de estado llamado Texto personalizado. Este elemento puede mostrar el texto elegido en la barra de estado. Puede utilizar esta función para crear un separador entre los elementos de la barra de estado.
Primero habilite esta opción con una pulsación corta sobre ella desde este menú
⇑ MENÚ SUPERIOR → → Barra de estado → Texto personalizado: 'KOReader'
Luego, mantén presionado el texto nuevamente para abrir su configuración . Ingresa un carácter de "espacio" en el primer cuadro e ingresa la cantidad de repeticiones en el segundo cuadro, lo que determinará el ancho del separador.
Puedes elegir otro carácter como separador. También puedes mover este elemento como otros elementos de la barra de estado para cambiar su orden.

While setting the warm light percentages for different intervals, you can also set that interval to Night Mode, which inverts the screen colors when that interval starts. If your minimum frontlight is still too bright or if you prefer a dark page background, you can activate this feature. To enable this, in the dialog below, tap the Night mode checkbox and tap Set.
When you do this, a moon icon will appear in the menu next to this interval. To disable night mode, just disable the Night mode checkbox in that interval.
Frontlight auto on/off
This feature turns your frontlight on at sunset and turns it off at sunrise according to your Currently active parameters in this plugin. You can override this change by manually turning your frontlight on/off. On the next sunrise/sunset, AutoWarmth will toggle it again if it is necessary. You can activate it by selecting Frontlight off during the day menu item in this plugin.
Faster warmth change tip
If you want your frontlight warmth to change quickly instead of a more gradual change:
Set the mode to Fixed schedule following the instructions above
Y ajuste la configuración de manera similar a esta imagen:
As you can see in these settings above, there is only a one minute difference between day-night transition. So the screen warmth goes from 0 to 100 (or reverse) in only one minute. You can increase this time separation to make the transition duration longer.
Fuentes
¿Cómo puedo añadir mis propios tipos de letra?
KOReader admite los formatos de fuente más utilizados TrueType (.ttf) y OpenType (.otf). Los archivos de fuente con estas extensiones se pueden copiar directamente a la carpeta /koreader/fonts/ en tu dispositivo. Revisa la wiki para más información:
When starting up, KOReader compiles the available fonts from the font metadata/info and classifies them according to family and weights. This means you can add different weights and variants of a font and KOReader will try to use the most suitable one. Since it takes font family information from metadata, font names are not important when copying to your device. Installed fonts will be available after restarting KOReader.
Here are some example fonts that look good on an e-ink screen. You can find more of them on the Google Fonts website:
If you are planning to use your own monospace font, probably you already have a favorite one, so we are not offering any examples here. But you can find and compare many monospace fonts at this page: https://www.programmingfonts.org/
Previsualizar los tipos de letra en el dispositivo
KOReader can generate a document with sample text rendered with all the fonts installed on your device. This allows you to quickly compare the look and features of the fonts like ligatures and character sets in non-Latin scripts like Greek, Hebrew or Chinese. You can access this feature via:
⇑ MENÚ SUPERIOR → → Fuente → Ajustes de fuente → Generar documento de prueba de fuente
Escala tipográfica monoespaciada
If your book includes parts with Monospace fonts (like in programming books), Monospace font might look disproportional even if they are technically at the same size. This is caused by differing font metrics. If you want to fix this difference, KOReader has an option that allows you to adjust the relative Monospace font size.
⇑ TOP MENU → → Font → Font settings → Monospace fonts scaling
Here you can increase or decrease the size of your Monospace font by adjusting its scaling as a percentage of the default size.
Utilizar tipos de letra distintos en un documento
In HTML/CSS based documents like EPUBs, books can specify to use fonts by family instead of a specific font name. These families can be Serif, Sans-Serif, Monospace, Cursive, Fantasy, Emoji, Fang Song and Math. For example in a book, normal text can be shown in Sans-serif while dialogues are shown in Serif font. KOReader normally uses your default font for all these families except Monospace and Math (which is determined by the style of the text nodes, for example 'font-family: serif'). If you want these families to look distinct, you can assign specific fonts for them here:
⇑ TOP MENU → → Font → Font-family fonts
To change a family font for the current book just tap on the desired font name. If you want to set this for all your books, long-tap to set it as a Default (★). If a book abuses this font family feature to the point where your default font is hardly used, you can disable that family font for this book by unchecking the association.
Cambiar fuente rápidamente
If you are switching between fonts frequently (i.e. monospace for programming books and serif for novels) there is a workaround which makes this easier than going into the menu each time. You can create profiles for your fonts and all font related settings like line spacing, contrast, bold etc. and add these profiles to a Quick Menu. So with a single gesture you can open your font selection menu and change the font like shown in the image below:
Hay muchas maneras de moverte a través de tu documento en KOReader.
You can use the SKIM WIDGET, BOOK MAP or PAGE BROWSER features.
Widget de Skim
You can also open this widget with a long-tap on the Status Bar in addition to:
⇑ MENÚ SUPERIOR → → Hojear documento
Marcas de capítulo
KOReader can show chapter boundaries from your documents on the SKIM WIDGET and PROGRESS BAR.
If your document has too many heading levels, your chapter marks can look crowded like the example above. You can change the depth of visible ToC mark levels via:
⇑ MENÚ SUPERIOR → → Ajustes → Barras de progreso
También se puede emplear este sumario reducido para:
títulos de capítulo (si se muestra en la Barra de estado)
navegación por capítulos
tiempo de lectura restante estimado
Estas opciones están en el mismo menú.
If your document doesn’t have a Table of Contents, you can enable ALTERNATIVE TABLE OF CONTENTS. When this setting is enabled, KOReader will build a ToC from document headings (if available) or from individual HTML files in the EPUB. Long press on this menu item for extra info:
⇑ MENÚ SUPERIOR → → Ajustes → Índice alternativo
Puedes encontrar más información sobre las herramientas de índice disponibles en KOReader en esta sección relacionada de la guía: HERRAMIENTAS DE ÍNDICE
Mapa del Libro
Book map is a powerful and unique feature of KOReader which can be very useful for getting an overview of a book. For example if you are reading a book non-linearly by skipping some parts to read them later, it would be hard to track your progress. Book Map can show you which parts of the book you have already read, at a glance.
Puede asimismo:
Ver cuanto tiempo has pasado en cada página (si el complemento Estadísticas de lectura está activado)
Check which pages have bookmark, highlights and notes
Navigate directly to any part of the book like the SKIM WIDGET
You can access Book Map via menu and you can also assign a gesture for quicker access:
⇑ TOP MENU → → Book map
Interfaz de usuario y controles
When you open the Book Map first time while reading a book, it will be in Grid View mode, fitting all chapters on a single screen to give the best initial overview of the book’s content. To get a detailed information about usage, tap the info icon at the upper left corner. You can close the Book Map by tapping X on the upper right corner or with any multiswipe gesture (UP-DOWN, LEFT-RIGHT etc.).
You can customize Book Map by changing these options:
- First try swiping LEFT and RIGHT along the bottom edge of the screen to change width of columns indicating pages and observe how it changes the scale of map
- Then try swiping UP and DOWN along the left edge of the screen to change chapter title depth and switch to the Flat View. See examples below.
In addition to default Grid View above, here you can see the Flat View on the left and Grid View without chapter titles on the right. Note the changing left vertical scrollbar between views. If you want to switch back to the default view, you can long-press the info icon at the upper left corner.
Opciones del mapa de libro
When you tap the menu icon on the Book map screen you are presented with the menu above. Menu options are explained below:
About book map: Short explanation of Book map usage and icon descriptions.
Available gestures: Gestures you can use to change the settings of Book map instead of using this menu.
Page browser on tap: If this is checked, when you tap on a page in Book map, Page browser opens. This shows you an overview of the area you selected. If you disable this option, a tap in Book map directly takes you to that page. But remember, depending on factors like your screen size, touch screen sensitivity, tap accuracy etc. you might end up in adjacent pages.
Switch current/initial views: If you customized your Book map view, tapping this switches between the default view and your customized view.
Cambiar vistas de cuadrícula/plana: Cambiar entre las vista de capítulos separados o capítulos continuos.
Niveles de capítulo: modifique la profundidad de niveles de capítulos y subcapítulos.
Page slot width: Make each page slot wider or narrower.
10-page markers: As you increase this value, first it will add markers to every 10th page, then it will make them bigger and eventually it will add markers to every 5th page.
Navegador de Páginas
Page Browser can be used to navigate between pages like in a photo album by showing thumbnails of the pages as a grid. You can open Page Browser by tapping on the Book Map or from the menu. You can also assign a gesture for quick access.
⇑ MENÚ SUPERIOR → → Navegador de página
You can change the number of pages shown by swiping along the TOP and LEFT sides of screen. Icons on the bottom are the same as Book Map. Actually the bottom part is a linear version of the Book Map.
Alternative theme for Book map and Page Browser
Book map and page browser has an Alternative theme with a different shading scheme which you can activate from their hamburger menus. This theme uses alternating colors for the chapter headings so chapter boundaries is more visible in the Book map and Page browser. But the usage of gray color in this theme requires flashing to black so it might be distracting for some users. You can try both and use the one you like.
Herramientas de sumario
Some of the digital books you come across might not have a proper table of contents (ToC). Depending on the preparation of the book, you can experience these ToC problems:
No ToC in the book, so you can’t jump between the chapters or see the remaining reading times
Hay un sumario pero no es muy útil dado que tiene títulos de capítulos incorrectos o faltan estos
KOReader tiene algunas funciones que puedes utilizar al leer libros con una sección de índice problemática.
Note that Alternative table of contents is not available on fixed layout documents like PDF, DJVU etc. because it requires HTML tags to create a ToC. Custom table of contents and Custom hidden flows features are available on all file types.
Crear índice automáticamente: ÍNDICE ALTERNATIVO
La primera función es el Índice alternativo que puedes encontrar en:
⇑ MENÚ SUPERIOR → → Ajustes → Índice alternativo
INFO An EPUB document is basically a ZIP file containing one or more HTML files. Your book might be one big HTML file for the whole book or it might contain separate chapters as individual HTML files (which is a better structure).
Alternative table of contents tries to create a ToC from the headings in your book (H1 to H6 tags in the HTML files in your EPUB). If your book doesn’t contain any headings, it will try to build a ToC from the document fragments (individual HTML files in your EPUB book) which will point to the beginning of each file.
You can choose which heading levels to include (or ignore) in your ToC from this menu:
⇑ TOP MENU → → Style tweaks → Miscellaneous → Alternative ToC hints
Crear índice manualmente: ÍNDICE PERSONALIZADO
Custom table of contents feature allows you to create your own ToC from the selected parts of your book. This ToC can contain only one level so you can’t have sub-chapters while using this feature. To create your own ToC, first enable:
⇑ MENÚ SUPERIOR → → Ajustes → Índice personalizado
Once you enable this feature, new menu items will be added to the user interface which allows you to select your chapters. You can add a chapter to your ToC from two places:
From a highlight: While reading a book, select a text like you are highlighting it or long press on a word. In the popup menu you will see the Start TOC chapter item. When you press on it, you will see a dialog asking you to enter your chapter title. The text you selected will be already entered in the dialog. Edit your title if necessary and press create.
Desde el navegador de página: Abrir el navegador de página vía
⇑ MENÚ SUPERIOR → → Navegador de página
Long press on the page thumbnail that you want to be the beginning of your chapter and select Start TOC chapter item from the popup menu. You will see a dialog asking you to enter your chapter title.
When you are done creating your ToC and don’t want to see these extra buttons, you can disable them by unchecking:
⇑ TOP MENU → → Settings → Custom layout features → Edit mode
Creating this ToC will not alter your original ToC which comes with your book. You can clear your Custom table of contents from this same menu (in case you want to create a new one). And you can disable this feature completely in the same way you enabled it, if you want to return to the original ToC. Note that if you disable this feature after creating a custom ToC to return to the original one, your custom ToC will not be deleted. You can still switch between the original and your custom ToC.
Excluir secciones del libro: FLUJOS OCULTOS PERSONALIZADOS
Some books or documents might contain long footnotes or bibliography sections. Like a scientific book which is 250 pages long but last 50 pages are Appendices, Index and References. Normally these pages are included in the progress bar and reading time calculations since they are part of the book. But generally these sections exist as a reference and they are not read completely so you might want to exclude them to make your remaining page count and time estimates more accurate. Or maybe you have an anthology book which contain some stories you have already read. Custom hidden flows feature of KOReader allows you to exclude these kind of parts of your book.
Echa un vistazo a la imagen para tener una vista general del proceso. Los pasos se explicarán después de la imagen:
How to exclude a section by creating a hidden flow
Ve a la primera página de la sección que quieras excluir
Abrir el Navegador de página vía:
⇑ MENÚ SUPERIOR → → Navegador de página
Long press on the page thumbnail that you want to be the beginning of your excluded section and select Start hidden flow here item from the popup menu.
You will see that the pages starting from your selection now have a gray hatched background.
Now go to the last page of your excluded section. You can navigate there from the Page browser or using other ways like Book map, Skim widget etc.
Once you are at the last page of your excluded section, open the Page browser again (if you are not already in it).
Find the last page of your hidden section and long press on the next page. Choose Restart regular flow here from the popup menu. You will see that the background of the remaining pages will return to normal color, indicating the end of hidden flow and the beginning of regular flow.
Working with the hidden sections
When you create a hidden flow section as described above, KOReader’s behavior will be similar to the situation as if you removed a section of a paper book by cutting it out:
These hidden flow sections will be skipped when turning pages. For example assume that you created a hidden flow for Chapter 10. Now you are on the last page of Chapter 9. When you turn the page, you will see Chapter 11.
Page numbering will continue as if these hidden flow sections do not exist.
These hidden sections will not be shown in your Progress bar (but read the explanation below) and will not be considered in time to read calculations. But they will still be visible in the Skim widget.
Following direct links to the pages included in these hidden flow sections will still work. Also you can still reach these sections from the Table of contents, Book map, Page browser, Skim widget.
As we said above, your hidden flows will be excluded from your Progress bar. But if you jump to one of your hidden sections using any of the methods mentioned above, your Progress bar temporarily becomes this hidden section’s progress bar. You can imagine this as the progress bar is zooming into that hidden flow section. If you exit out of this hidden section by turning the page at the end of it, or using other navigation tools, your Progress bar will go back to showing the whole book again (with your custom hidden flows again not visible).
Removing and cleaning up hidden sections
You can remove individual hidden flow sections from the Page browser in the same way you created them. You can also clear all of them at once with the menu item:
⇑ TOP MENU → → Settings → Custom layout features → Clear all marked pages
As you work on creating hidden flows by tagging pages as Start hidden flow or Restart regular flow, some of the previously made ones may stop having an effect. For example in the case that you make Start hidden flow a few pages before an existing Start hidden flow, that existing one is no longer involved. This overlapping or obsolete tags are remembered for practical purposes. Again in the previous example, if you end that second hidden flow before the existing-but-no-longer-involved Start hidden flow, this deactive one will be involved again. You can clear all these inactive markers if they interfere with your custom flows, or once you finish making your hidden flows and happy with the results:
⇑ TOP MENU → → Settings → Custom layout features → Clear inactive marked pages
Hidden sections and progress bar
As we said above, your hidden flows will be excluded from your Progress bar. But if you jump to one of your hidden sections using any of the methods mentioned above, your Progress bar temporarily becomes this hidden section’s progress bar. You can imagine this like the progress bar is zooming into that hidden flow section. If you exit out of this hidden section by turning the page at the end of it, or using other navigation tools, your Progress bar will go back to showing the whole book again (with your custom hidden flows again not visible).
MARCAPÁGINAS, RESALTE Y NOTAS
KOReader gives you options to interact with your book like you can do with a real book:
Bookmarks: You can add (and remove) a bookmark by pressing the upper right corner. This is the equivalent of folding the corner of a page on a real book and shows a similar icon when you enable it.
Highlights: You can highlight text in 4 different styles. In the image below, you can see a normal paragraph followed by different styles of highlights. Lighten (with gray background), Underline, Strikeout and Invert.
You can use all these styles at the same time, like they are different colored highlight markers. Or you can decide your favorite style and set it as default from this menu by long pressing:
⇑ TOP MENU → → Highlight style
Notes: You can also add notes to your highlights. Just tap on a highlight and choose Add note from the popup menu. You can also choose a Note marker that shows which highlights contain a note. There are three styles: Underline, Side line and Side mark (which is the pencil icon shown on the right side of the picture below):
To enable this feature and choose a Note marker style, go to:
⇑ TOP MENU → → Highlight style → Note marker
Cómo resaltar
KOReader tiene dos modos de resalte adecuados para distintos casos de uso:
El modo normal es semejante a seleccionar un texto con el dedo en un teléfono o tableta y es más práctico si sus resaltes son más cortos que una página.
Select and highlight mode is more suitable for highlighting longer passages which cross page boundaries. It might also work better if you have touch screen sensitivity problems or motor control issues with your hands. Because in this highlight mode you don’t need to drag your finger along the screen.
Modo normal
This mode is similar to selecting a text with your finger on a phone/tablet.
Mantenga presionada la palabra inicial
Mueva el dedo hasta el final del pasaje
Retire el dedo
When you reach page boundaries, KOReader will turn the page for you to continue highlighting (only in EPUB/HTML documents). You can disable this feature from:
⇑ TOP MENU → → Taps and gestures → Long-press on text → Auto-scroll when selection reaches a corner
Modo selección y resalte
INFO If you have dictionary lookup enabled when long pressing a word, you have to drag your finger to initiate this mode.
⇑ MENÚ SUPERIOR → → Pulsaciones y gestos → Pulsación larga en texto → Diccionario en selección de una sola palabra
Long-press (or drag if dictionary lookup is enabled as described above) on the starting word, popup menu will show up.
Tap on Select, now you are in highlighting mode. When you are in this mode, you will see an indicator at the upper left corner of the screen (which you can tap on it to get more information). You can cancel highlighting by tapping on the beginning of highlight again. You can turn pages with taps/swipes and freely navigate the document (TOC, skim etc) in this mode.
Long-press (or drag if dictionary lookup is enabled as described above) on the ending word for your highlight, menu will show up again.
Tap Highlight this time to finish highlighting the passage.
This dialog normally opens at the center of the screen. If you want this dialog to open closer to your highlight location, you can change the center option here to gesture position (located on the second page of this menu):
⇑ TOP MENU → → Taps and Gestures → Long-press on text → Highlight dialog position
TIP There is a faster method for this mode if you don’t need long-press menu items shown above. You can disable the popup menu completely so when you long-press on a word you will immediately enter the Select and highlight mode. This method is much faster and you can highlight any length of text with just two taps. To use this method enable this option:
⇑ MENÚ SUPERIOR → → Pulsaciones y gestos → Pulsación larga en texto → Seleccionar y resaltar
TIP KOReader can highlight a passage in different styles. If you use Lighten option, text background will be gray. Due to e-ink limitations, screens can’t change from white to gray directly, so highlighted part first has to turn black and then gray. If you want to avoid this flashing, you can choose Inverted as your highlight style. In this mode text background will be black so it can be set without flashing. You can adjust these highlighting options via:
⇑ TOP MENU → → Highlight style
TIP You can add multiple highlights and notes to the same section of text. If they are overlapping, when you tap on a highlight you will be presented with a menu to choose which highlight you want to edit.
Seleccionar puntuación
When you are highlighting, KOReader tries to include the related punctuation marks around your selection. For example if you highlight from the first word to the last word of a sentence, KOReader will automatically include the punctuation marks at the both ends of the sentence to your highlight.
But if you start highlighting from the middle of a sentence, period at the end will not be included because KOReader assumes that you want to make a partial highlight. So if you want the punctuation marks to be added to your highlight, be sure that you select the whole sentence. Also you can add these marks later by long pressing the Highlight edit buttons.
Editar un resalte
When you tap on an already highlighted text (without a note), you will see this popup menu. Delete and Add note items are clear. Bottom row menu items are used to extend or shrink the highlight.
INFO This adjustment works only on reflowable documents like EPUBs. If you want to extend or shrink a highlight on PDFs, you have to delete it and highlight again due to the limitations of the PDF format.
When you tap on an already highlighted text with a note added, you will see this popup menu. Tap on Edit highlight to open the menu above where you can edit both the highlight and the contained note:
On your Bookmarks page you can filter the view to see only one type of bookmark by pressing the menu icon ( ) You can also filter by highlight style:
Exportar sus resaltes
After finishing a book, you can move it to a specific folder for archiving or processing purposes. Enable Move to archive plugin and set your target directory in the plugin’s settings (Set archive folder). After this, you can move a book to your archive folder using:
Move to archive plugin menu
With a gesture or
With a Quick Menu entry
KOReader provides different ways of exporting your highlights and notes from your reader device:
1. Export Highlights plugin
This versatile plugin can export your highlights to local files or online services.
Local export: You can export your highlights to your device in these file formats:
Texto (.txt)
HTML (.html)
Markdown (.md)
Kindle Clippings (.txt)
JSON (.json)
You can choose your preferred export formats from:
⇑ TOP MENU → → Export Highlights → Choose formats and services
You can see the export location (and also change it if you want):
⇑ TOP MENU → → Export Highlights → Choose export folder
Online services: You can also export to these services over the network:
After selecting your formats, you can export the notes for the current book or all the books in your library from the same plugin menu.
If you want to export only some of the books in your library, you can do this from the File Browser:
Seleccione varios libros en el navegador de archivos
Tap on the menu button (shown as a check mark) at the top right corner
Select Export highlights from the menu shown
2. Utilizar KoHighlights
KoHighlights is an external program that you can install on your computer. It can access your book notes and highlights when you plug your reader to your computer. Check the project page for download and instructions:
Calibre is an external program that you can install on your computer. You can import highlights into your Calibre database with its KOReader Sync plugin. You can install the mentioned plugin within the Calibre application. Check the project page for download and instructions:
INFO When you open a document in KOReader, it creates a directory alongside the document with same name as the document. This directory contains a .LUA file which includes all the highlights, notes and user options (formatting properties etc.) related to that document. You can manually backup/restore these directories.
LECTURA DE ARCHIVOS PDF
Lectura de archivos PDF grandes en una pantalla pequeña
KOReader provides you many ways to read a PDF/DJVU document which is optimized for bigger (generally it is A4 or Letter) page sizes on your smaller screen device:
1. You can enable REFLOW
⇓ BOTTOM MENU → → Reflow
Reflow tries to extract the text portion from your document (if it is available) and format it as a single column. Results are generally satisfactory. You can also set this as DEFAULT by tapping and holding on it.
2. You can enable ZOOM TO CONTENT
⇓ BOTTOM MENU → →
With this option KOReader tries to crop margins from your document so text may look bigger on your screen. You can set FIT to WIDTH in the same menu which will try to fit only page width instead of whole page, so your text will look bigger.
3. You can try to use your device in LANDSCAPE orientation
This will make your screen wider so your document may look big enough to read comfortably.
⇓ MENÚ INFERIOR →
4. You can see your document at full size and scroll the screen to read different parts
This is especially helpful with comic books. First enable COLUMN MODE from this menu item:
⇓ BOTTOM MENU → →
Then select an appropriate flow direction for your document from the same menu:
For example if you are reading an article which has two columns, you will scroll down until the end of page reading left column then go to right upper side to continue reading right column:
Or if you are reading a comic book, you will want to go “right → down left → right” in a zigzag pattern:
For a Japanese comic book (right-to-left panel order) this might be the reverse:
In this mode you can also adjust Horizontal/Vertical Overlap and Number of Columns from the same menu to fit the text on your screen better. Feel free to experiment with these settings.
Explicaciones De Elementos Específicos Del Menú Inferior De Pdf
CONTRAST This setting adjusts black levels in your document. Be aware that same contrast value applies to both text and images in your document. If you set it very high, your images may become too dark to be readable.
DEWATERMARK Removes watermarks from the rendered document. It can also be used to remove gray backgrounds. This feature can convert a grayscale or color document to black & white to produce more contrast for easier reading.
RENDER QUALITY(REFLOW MODE) Sets the quality of text and image extraction processing and output. HIGH is more pleasing but it can be much slower (several seconds for page turn) than DEFAULT depending on your document. If your PDF/DJVU files are slow, this is the first setting you should check.
DOCUMENT LANGUAGE Sets the language to be used by the OCR engine.
FORCED OCR Force the use of OCR even if the document has a text layer
WRITING DIRECTION(REFLOW MODE) Text direction of original document. Set to RTL for languages like Arabic and Hebrew.
DOCUMENT COLUMNS(REFLOW MODE) Number of text columns in the original document.
AUTO STRAIGHTEN feature can straighten the pages of a problematic document, for example pages of a PDF which are scanned with an angle. It is available in PDF, DJVU, CBZ/CBT documents and image files. To enable, choose the maximum tilt angle which KOReader will try to correct. If it doesn’t correct you might have to choose a bigger angle. Note that this feature might slow down your reader depending on several factors.
OCR (Reconocimiento Óptico de Caracteres)
OCR (Optical Character Recognition) is the process of extracting text from images into machine readable format. In KOReader context, it is generally used for extracting text from scanned book pages in PDF files. KOReader relies on Tesseract Open Source OCR Engine for this task (https://github.com/tesseract-ocr/tessdoc).
Para utilizar esta función es necesario:
Instalar datos lingüísticos de Tesseract en KOReader
Add newly installed languages to koreader/defaults.lua configuration file (necessary only if your language is other than English or Chinese)
Esta funcionalidad facilita la lectura de historietas en pantallas pequeñas. Puede activarla mientras lee un documento PDF, DJVU, CBZ o CBT a través de:
⇑ TOP MENU → → Panel Zoom (manga/comic)
When this option is enabled, KOReader tries to find the boundaries of rectangular panels on the screen. If you long-tap on a panel, KOReader zooms in to that panel. As you can guess, this feature works best with comics that has clean panel boundaries. Procedure can be seen below:
If you want to use this feature with other file types like EPUB, FB2, HTML or image files, you should open the file with a different engine: In the File Browser long-tap on the file name, tap Open with… and select MuPDF.
KOReader can reflow PDF documents (this option can be found in the bottom menu while reading a fixed-layout document like PDF) to make them suitable for the small screens of e-readers. But for best results, you may want to convert your documents into more flexible EPUB format. You can use Calibre (https://calibre-ebook.com/) for all kinds of conversion between formats.
There are many ways to transfer your documents to your device. Note that you may need to restart KOReader to index the transferred documents (or refresh directory if you have Pocketbook/Android).
In addition to transferring files the same way you would with the built-in reader application, other options are available depending on your device:
USB mass storage mode within KOReader: This mode is available for KOBO and some CERVANTES devices.
Cloud storage (Dropbox/FTP/Webdav): To use this function you have to add accounts for a cloud storage server via menu shown below. Process is explained via INFO buttons while adding accounts:
⇑ MENÚ SUPERIOR (en explorador de archivos) → → Almacenamiento en la nube
SSH/SFTP access: KOReader can act like an SSH server, which you can access from a computer to transfer files (available on Kobo, Kindle, Cervantes). You can use an SFTP application (like Filezilla) or access via your file manager if your operating system supports. Check wiki for how-to: https://github.com/koreader/koreader/wiki/SSH
Some books don’t come with proper book covers. Or they may have their cover on the second page so it doesn’t show up properly. Or maybe the cover is not suitable for e-ink (too light or dark). Or you prefer to set some image from the book as cover.
In situations like this you can quickly take a screenshot and set it as the current book’s cover. Screenshot gesture is a long diagonal swipe by default. Also touching opposing diagonal corners will take a screenshot. You can use this second shortcut when viewing an image. After taking your screenshot you can select Set as book cover from the dialog.
You can remove this custom book cover here:
⇑ MENÚ SUPERIOR → → Información del libro
On the book information page, long-press on the Cover image item and then select Reset custom.
You can also reset the book cover with the Reset dialog, which you can access by long-pressing the filename in the File Browser.
WARNING Be very careful when using this Reset dialog and be sure that only Custom cover image item is checked otherwise you can reset everything related to your book accidentally.
Optimización de documentos EPUB/PDF para su dispositivo lector móvil
Most widely used applications for converting or optimizing your document for your mobile reading device are Calibre (EPUB, Kindle focused) and K2pdfopt (PDF focused).
Calibre can convert your documents between many formats. It also has a built-in editor that allows you to edit e-books (and fix problems) in the most popular e-book formats, EPUB and Kindle. https://calibre-ebook.com/
K2pdfopt optimizes PDF/DJVU files for mobile e-readers and smartphones. It works well on multi-column PDF/DJVU files and can re-flow text even on scanned PDF files. It can also be used as a general PDF copying/cropping/re-sizing/OCR-ing manipulation tool. https://www.willus.com/k2pdfopt/
OCRmyPDF is a command line application which can add an OCR text layer to scanned PDF files (containing only images without text), allowing them to be searched or copy-pasted. It can especially be useful for reading old scanned books. It can also optimize the images for a smaller file size. https://github.com/ocrmypdf/OCRmyPDF
SingleFile is a browser extension for Mozilla Firefox, Google Chrome and Microsoft Edge. This extension allows saving a web page as a single .html file with all resources (images, stylesheets, scripts) embedded. https://github.com/gildas-lormeau/SingleFile#install
Soporte de archivos ZIP
KOReader can read files stored/compressed in ZIP files. A ZIP file can contain many types of documents like html, txt or images. KOReader can open your ZIP file properly if you give it a hint for the type of file in the ZIP archive. If you give your file only a .zip extension, KOReader will assume that this archive contains images and try to open it like a CBZ file.
DEFAULT CASE: yourfilename.zip - Assumed to be a zip file of images (and opened by MuPDF engine)
If your zip file contains one of these types (instead of just images), please name it accordingly:
Archivos de registro de texto: nombredearchivo.log.zip
Markdown: nombredearchivo.md.zip
Formato de texto enriquecido: nombredearchivo.rtf.zip
Texto sin formato: nombredearchivo.txt.zip
If the documents are not named like this, the wrong reader/format engine is likely to be used and you will see the No reader engine for this file or invalid file message. You can rename this file as explained above or long-press the filename and then choose Open with... to select the correct engine.
Optimización de manga para su dispositivo lector móvil
If you like reading manga books on your e-ink device there are some tips that can make your experience better. Preparing your own manga files is the best solution if you're not satisfied with how comics look on your device.
Tipo de archivo
File types like MOBI and EPUB are not suitable for handling primarily image content (e.g., manga/comics). MOBI support in KOReader is minimal to nonexistent, and EPUB’s text rendering priorities can cause problems when showing full-page images. For further technical details:
Your best option is building a CBZ file which works better in KOReader. A file with .cbz extension is a zip file (with no compression) that is a collection of images. It saves multiple images, commonly .png or .jpeg files, organized into pages of the comic. KOReader can also open CBT files, which are similar to CBZ files but use TAR archive format.
Easiest way to convert a manga to CBZ is to get the manga as images from various websites, then convert them using Kindle Comic Converter (https://github.com/ciromattia/kcc). There are some useful settings like auto-rotating two-page splits to landscape and applying dithering so that eink-rendered gradients are smoothly dithered without jagged layers.
Resolution
The best results can be achieved by resizing your images to exactly your e-reader screen size. A screen-specific CBZ which targets the exact screen size of the device, prevents rescaling during reading. KOReader downscales your images to your screen size while reading but this is not recommended because KOReader adds a dithering pass before scaling and this causes loss of quality.
But if you want to use your hand made CBZ on more than one device or you want to preserve high resolution for future proofing, your best option might be to make the CBZ for your highest resolution device. Or pick an arbitrary "high" resolution, possibly one that matches the source. 300 PPI or better (up to 450 or even 600), unless the source is lower of course. If we assume a screen size of 8", 1500×2000 is a good target resolution. For bigger images, you should try it on your device and see whether it can deal with it. Especially old Kindles with low memory can struggle with sizes like 3000×4000 for example. If you're automating the process, it might be worth considering creating both a lower and higher quality version (e.g., at 200/400 or 300/600 DPI).
INFO KOReader doesn't parse spine page-progression-direction="rtl" attribute of the books. So it doesn’t change page turning direction even though the file was created with right-to-left reading. Users can switch this via:
⇑ TOP MENU → → Taps and gestures → Page turns → Invert page turn tap and swipes / buttons
Advanced preparation of manga
The following is an example procedure to process one manga file:
Download your manga from the source of your choosing (i.e. HakuNeko)
Unpack the manga file. Now you should have a directory that contains only images (or subdirectories with images, no archives)
Process this directory with KCC. Each directory will produce a single CBZ file, so if you want to make several volumes at once, select multiple directories at once
Some useful settings of KCC:
Spread splitter: This feature detects double pages and allows you to rotate or cut them in two.
Upscaling: Enlarge images that is smaller than your target resolution.
Modo inmersivo en KOReader
If you would like to enjoy your manga in a more immersive way, make sure that you selected the exact same resolution as your device’s screen resolution in KCC when creating your CBZ file. Also you can hide the bottom progress bar while reading your manga in KOReader. So you will have an immersive full screen view of your manga without obstructions.
Extra step for smooth gradients !!! ADVANCED
After using KCC to create a CBZ file, you can apply additional dithering to the images. This way, eink-rendered gradients will be smoothly dithered without jagged layers. This step will produce fine-tuned manga volumes which look better in KOReader.
You can use ImageMagick to process your images. ImageMagick, is a powerful open-source software suite for displaying, creating, converting, modifying, and editing raster images. You can download ImageMagick and use it from the command line to process many images at once.
Unpack the prepared CBZ file that you created with KCC,
Extract these three files next to your images that will be processed
Edit the _magick_manga_ditherN_resize.bat and change the resolution to your device resolution (in both places in the BAT file).
WARNING Next step will replace all the images in the directory with the processed ones. So make sure that you have a copy of them in some other directory if you want to keep the originals.
Run _magick_manga_ditherN_resize.bat to resize and dither the images.
Assuming you have 7-Zip installed, run _batch_archive.bat to pack all the processed images into a CBZ archive.
Reversing the page turn direction for authentic Japanese manga !!! ADVANCED
You can make KOReader turn pages from Left to Right, so that swipes and tap zones are swapped. To enable this, add the following lines to this file → /koreader/settings/directory_defaults.lua
where /storage/emulated/0/Books/manga is the absolute path to the directory containing your mangas. After this change, when you open a file from the mentioned directory, your swipes and tap zones will be swapped.
Tip when reading serialized books like manga
When you reach the last page of a book, KOReader shows you a dialog. In this dialog there is an Open next file action which will open the next file in the same directory as the current book. So you can put your series in separate directories and read them one after another without going back to the File Browser.
When opening this next file, KOReader skips the files that you have marked as finished. This feature is useful for example when you have a folder of manga files and you have already read some of them. You can mark a file as finished from the end of book dialog shown above. Also you can mark it from the File Browser by long-pressing on the file. After copying them to your device, you can:
Open the File Browser in KOReader
Long press on the ones you already finished and tap Mark as finished
Now you can read all the files by just tapping Open next file at the end of the book. KOReader will skip the ones you have already read.

MENÚ RÁPIDO Y PERFILES
Menú Rápido
Quick Menu is a recent feature of KOReader which allows you to have a quickly accessible personalized menu. You can assign this menu to a gesture and access it with a single swipe. You can see an example menu on the right. You can even have a menu longer than your screen, it is scrollable.
Basically, any action you can assign a gesture can be added to the Quick Menu. Its advantages are:
You don’t need to memorize lots of gestures for every action.
Some infrequent actions may not worth a gesture but it can be too much hassle to find it in the menu system. You can add this kind of rarely used actions to this menu instead.
If you are installing KOReader for a relative or friend, you can add their favorite actions to this menu so they don’t even need to go into the menu system while using KOReader.
An example Quick Menu:
There are two methods for creating a Quick Menu. Easy and Advanced. If you need only one menu, Easy method should be enough for you. If you want show different menus with different gestures you need to use Advanced method. Another advantage of Advanced method is that, if you want to use another gesture for your menu you can easily move it to another gesture. If you want to use another gesture while using the Easy method, you have to re-create your menu under the new gesture.
Easy method
Go to Gesture Manager menu via:
⇑ TOP MENU → → Taps and Gestures → Gesture Manager
Decide a gesture for opening your menu and tap on it.
Choose the actions you want to see in your menu from the gesture configuration menu. You can select many actions at once of course.
After selecting all your actions, you will tell KOReader to treat this gesture as a menu. You achieve this by enabling Show as Quick Menu item on the second page as you can see in the picture below.
You can sort your menu items with the Sort option just below it.
Now you can launch your menu with the gesture you selected. If you want to change the menu items, you can open the gesture page and add/remove items.
Advanced method
INFO As we said above, if you are not planning to add more than one Quick Menu you don’t need this section.
Quick Menu is actually a Profile which appears on your screen as a menu. So first you have to learn about Profiles. If you already know how to use Profiles, you can continue reading, otherwise jump to the Profiles heading (next section), create a Profile with some items and come back here.
We assume that you already created a Profile as instructed in the previous paragraph. Now we will turn our Profile into a Quick Menu.
1. Go to your newly created Profile and enable Show in action list (shown in the image below). This will make your Profile visible in the Gesture Manager. Also enable Show as Quick Menu (also in the image below) so your profile will be shown as a menu instead of being silently executed.
2. Now we need a way to access our menu. Go to the Gesture Manager and choose a gesture from the list to assign to our menu. Let’s say we want to tap the corner of the screen to show menu. Now tap on Tap corner then choose Bottom left. Now tap on General and go to the second page. You will find your profile as Profile x where x is the name you gave to this Profile. Tap on its checkbox to assign your profile to this gesture.
After all the steps, now you should see your menu when you tap on the bottom left corner. You can edit your menu by going to its Profile page where you can add or remove items. Also there is a Sort item there so you can change the order of your menu items.
As we said, a Quick Menu is actually a Profile. Which means you can have more than one menu. You can create another Profile and follow the same steps to create another menu if you want.
Quick menu tips
Keeping the menu open after use
Normally after selecting an item in your Quick Menu, menu disappears from the screen. Sometimes you might want to keep the menu open after selecting an item. This allows you to adjust settings like these examples:
Incremental changes, like brightness increase/decrease, bigger/smaller font size, previous/next pages or chapters, etc.
Group of options that you activate in succession (but not simultaneously), like turning on wifi and after that starting the SSH server
You can enable this option from the following menu if you have a Gesture Manager based (Easy method) Quick Menu:
⇑ TOP MENU → → Taps and Gestures → Gesture Manager → “Your Quick Menu gesture” → Keep Quick Menu open
Or from this menu, if you have a Profiles based – (Advanced method) Quick Menu:
⇑ TOP MENU → → Profiles → “Your Quick Menu profile” → Edit actions → Keep Quick Menu open
Opening Quick Menu at the gesture position
Normally Quick Menu opens centered at the middle of the screen. If you are using your e-reader with one hand you can activate a setting which will open your menu at the gesture position. This way, menu will be closer to your finger and easier to access. To use this feature enable this option:
⇑ TOP MENU → → Taps and Gestures → Gesture Manager → “Your Quick Menu gesture” → Anchor Quick Menu to gesture position
INFO This is available only in a Quick Menu which is created via Gesture Manager (Easy method above).
Perfiles
A profile is basically a collection of actions that can be triggered with a single tap (like a macro).
As an example, imagine that when reading some type of books, you always:
Rotate the screen to landscape orientation
Increase the font size and contrast and
Turn the screen light on
With the profiles plugin, you can do all these at once with a single action.
INFO When you activate another profile, changes made in the first profile will not be reversed. For example, you activate a profile which sets your font size from 20 to 24. Then you activate another profile that adjusts your frontlight. Your font size stays at 24 after activating the second profile. Because profiles in KOReader doesn’t have an exit or reverse action.
To create a profile first be sure that Profiles plugin is activated. If you don’t see it under:
⇑ MENÚ SUPERIOR → → Perfiles
then you have to turn it on from:
⇑ MENÚ SUPERIOR → → Más herramientas → Gestión de complementos
Creating a profile
In Profiles menu tap New and give a descriptive name for your profile. Now you should see your new profile in the menu. Tap on it and you will see the screen on the left side. You can also Delete, Rename or Duplicate a profile from this menu.
When you tap on Edit actions menu item you will see the menu on the right. This is the same menu as the gesture selection menu and there are actions in many categories. Which means you can perform any Gesture action using a Profile.
You can now select several items from all these categories. The actions you selected here will be performed when you activate this profile.
Activating a profile
There are many ways to activate a profile:
You can activate a profile with a long press on its name from this same Profiles menu
You can activate a profile using a gesture. For this, you have to enable Show in action list from the profile’s menu. Now you can select it via:
⇑ TOP MENU → → Taps and gestures → Gesture manager → “ANY GESTURE” → General → Profile “Your profile name”
You can also activate a profile automatically when KOReader starts if you enable Autostart in the Profile’s menu. Note that this is only possible when KOReader is starting with the File browser or Last file.
Technical details of Profiles and Quick Menu!!! ADVANCED
In KOReader we have a set of actions/settings and this set can be created in two ways:
As a profile (which is explained as the Advanced Method and stored in settings/profiles.lua)
As a list of actions assigned to a gesture (which is explained as the Easy Method and stored in settings/gestures.lua)
This set can also be executed in two different ways:
Applying each action in the (sorted) order when triggered (as a Profile)
Showing it as a Quick Menu
Adding/removing actions of a set and enabling/sorting Quick Menu are done via the same actions menu. The only difference is that the actions menu in the Gesture manager has two more items (Pass through), that is why Show as Quick Menu and Sort items are on the second page.

Los parches de usuario son pequeños archivos escritos en el lenguaje Lua. Pueden cambiar la funcionalidad de KOReader sin modificar su instalación permanentemente. Pueden ser escritos por desarrolladores, otros usuarios o usted mismo (si tiene los conocimientos necesarios sobre las características internas de KOReader).
Puede encontrar una lista actual de Patches en la página wiki relacionada GitHub:
Basic usage – Adding an already written patch to your KOReader:
Create a directory named patches under koreader directory on your device (On Android this folder is located on the SD-card)
Download and put the patch file with .lua extension in this patches directory
Reiniciar KOReader
Patch manager
When you create a patches directory as instructed, a new plugin named Patch Management becomes available in the plugins menu after restarting KOReader. With this plugin you can see the list and status of your user patches and enable/disable them. You can tap About patch manager menu item to see more info.
Naming the patch
Execution order of a patch is determined by the first digit of the number in the patch name. For example: 2-TOC-title-patch.lua If there are several patches starting with the same digit, the execution order is the natural order (1<10<11<12<13<…<109<…<10010). If you are just downloading an already made patch you don’t need to change the file name.
Nombres que empiezan por:
0 - Se ejecuta muy pronto y sólo una vez tras una actualización
1 - Se ejecuta muy pronto en cada inicio de KOReader (pero después de 0 si procede)
2 - Se ejecuta después de que UIManager esté preparado en cada inicio de KOReader
3-7 - Reservado
8 - Se ejecuta antes de salir y antes de guardar los ajustes
9 - Se ejecuta justo antes de salir
If you have a problem with a user patch, you can revert to your previous configuration by removing the patch file.
CONSEJOS
Actualizar KOReader
KOReader se puede actualizarse a través de Wi-Fi. Puedes activar la comprobación a través de esta opción de menú:
⇑ MENÚ SUPERIOR → → Actualizar → Comprobar actualizaciones
Automatic dimmer
KOReader can dim your frontlight to preserve battery if your device is idle for a while. You can turn on and adjust this feature via:
⇑ MENÚ SUPERIOR → → Pantalla → Regulador automático
Recuento de líneas/palabras de una página
If you want to know how many lines or words are being shown on the current page you can see it at:
⇑ MENÚ SUPERIOR → → Información del libro
¿Cómo puedo añadir una contraseña de bloqueo en KOReader?
We don't have a direct option for this in KOReader. But there is a workaround to achieve this kind of lock screen functionality. You can set up KOReader to keep the screensaver on the screen until you enter a chosen gesture. To achieve this:
Choose any gesture (including the complex ones with custom multiswipes) and make it your "unlock" gesture by going to:
⇑ TOP MENU → → Taps and gestures → Gesture manager → "your selected gesture" → Device → Exit screensaver
Y entonces activa esta opción:
⇑ TOP MENU → → Screen → Screensaver → Settings → Keep the screensaver on screen after wakeup → Until 'Exit screensaver' gesture
Cambiar entre documentos rápidamente
If you need to switch between two documents (when comparing them for example), there is a quicker way than going through the File Browser. KOReader can open the last document with a gesture (←→← multiswipe). If you define a gesture’s action as Open previous document, you can switch between two documents quickly similar to Alt+Tab feature on the desktop computers. You can find this feature under:
⇑ TOP MENU → → Taps and gestures → Gesture manager → “ANY GESTURE” → General → Open Previous Document
Also you can use the History dialog to switch between documents quickly. The history screen can be opened with the →↑ multiswipe gesture. You can also define any other gesture for this of course.
Aplicar los valores predeterminados actuales a un libro ya abierto
When you adjust your document defaults like default line spacing or default contrast, this new value will only be used for the new documents you open after the change. Your already opened books will look the same. For example, if you change your default FONT, you will probably adjust FONT WEIGHT and LINE SPACING to more suitable values for this new font. Then probably you will want to apply these changes to all your opened books. With this feature you don’t need to change these values manually in all your opened books.
Puedes aplicar estos cambios fácilmente a tus libros ya abiertos eligiendo:
⇑ MENÚ SUPERIOR → → Restablecer los ajustes del documento a valores predeterminados
When you tap this option, your current book will reset to latest defaults you set. Don’t worry, this will only change the appearance of the book. Your reading position, highlights, notes and bookmarks will be preserved.
Guardar la configuración actual del libro como valores predeterminado
When you adjust a book to your liking, for example by changing line spacing, font contrast etc. you can save all the changes at once as defaults. Then you can apply these settings to other books with the Reset document settings to default option as explained above.
Puedes guardar tus cambios como predeterminados eligiendo:
⇑ MENÚ SUPERIOR → → Guardar los ajustes del documento como valores predeterminados
Evitar abrir enlaces accidentalmente
If your document has links and you are accidentally tapping them while turning the page or using other gestures, you can turn off Following links by tapping via this menu item:
⇑ TOP MENU → → Taps and Gestures → Links → Tap to follow links
After disabling this setting, to follow a link you have to long-tap on it and select Follow link from the popup menu. If you have the opposite problem and you want to make tapping links easier, you can enable Allow larger tap area around links from the same menu.
Optimizar la duración de la batería
Li-ion batteries experience more degradation at the extreme ends of their charge levels. To minimize this degradation and extend your battery life, you can limit your minimum discharge level to 20% and maximum charge level to 80% (as in electric vehicles and some newer phones). Which means you start charging your device when the battery goes down to 20% and unplug when it reaches 80% (or 25%-75% if you are extra cautious).
KOReader can warn you by showing an alert when charge level reaches your defined limits:
⇑ TOP MENU → → Device Status Alerts → Battery Level
Vigilar tu uso de memoria
In older Kindle devices some of our users reported crashes due to limited memory. KOReader memory usage can go up if you open many files in one session. Especially PDF’s increase this amount. You can add a memory indicator to your STATUS BAR and restart KOReader if this value gets high, to avoid crashes or reboots.
⇑ TOP MENU → → Status Bar → KOReader memory usage
También puedes configurar KOReader para que se reinicie automáticamente si el uso de memoria alcanza un límite a través de:
⇑ TOP MENU → → Device → Device Status Alerts
Comprobar los detalles de consumo de tu batería
Puedes ver las estadísticas detalladas del uso de batería a través de este menú:
⇑ MENÚ SUPERIOR → → Más herramientas → Estadísticas de batería
Comprobar las estadísticas detalladas del dispositivo
You can see your system information like CPU/DISK SPACE/RAM usage via this menu item:
⇑ MENÚ SUPERIOR → → Ayuda → Estadísticas del sistema
Cambiar la cubierta de tu libro
Desde este menú es posible cambiar la cubierta de su libro:
⇑ TOP MENU → → Book information → → Set cover image
Estadísticas de lectura después de medianoche
In reading statistics you can change the start of day used for calculations. This is useful if you are reading after midnight for example and want your reading session counted as today instead of the next day. This applies only to the Day timeline view and optionally to the Calendar view; it does not apply to any of the other statistics reports. You can set this time at:
⇑ TOP MENU → → Reading statistics → Settings → Daily timeline starts at...
SOLUCIÓN DE PROBLEMAS
Si tu libro va lento
KOReader is optimized to work fast even on the limited hardware of e-book readers. Generally thousand page books can be opened in seconds and page turning is immediate. Here we will talk about the reasons if your book feels very slow when opening, page turning or adjusting its appearance.
Si el libro problemático es un PDF:
EL propio archivo PDF puede ser demasiado grande para la memoria de tu dispositivo.
PDF file might contain very large image files. Even in documents with a normal text layer (which you can select and highlight) there might be another image layer embedded (generally a scan of the page). This slows down the opening and page turning because these large images has to be rescaled to fit on your screen and this process can be CPU intensive.
PDF file might have lots of individual elements that needs precise positioning, like a magazine page with lots of images and text boxes. In this case KOReader has to calculate and draw all these elements which can take time.
Auto straighten feature (which allows you to adjust the tilt of the page) might also slow down your reader.
If you set your RENDER QUALITY to HIGH while REFLOW is ON, text will be more pleasing but it can be much slower (up to several seconds per page turn) than DEFAULT depending on your document.
⇓ MENÚ INFERIOR → → Calidad de renderizado
Si el libro problemático es un EPUB:
EPUB files are basically composed of text and images with some rules to determine how these items are formatted on the screen. In ideal conditions, this is a fairly simple process so EPUB files are generally fast in KOReader. But some EPUB books add a great number of formatting rules that KOReader has to do many calculations just to show even a single sentence. This will slow down opening the book, turning the pages and changing the appearance properties like font weight or line spacing.
INFO KOReader doesn't support fixed layout EPUBs. They will open, but will render as reflowable EPUBs and probably won't look nice or readable.
EPUB files are ZIP archives that contain HTML files. Some books can be a single HTML file while others may be composed of multiple HTML files like each chapter of the book is a separate HTML file. If your book is only a single HTML file, partial rendering can not work. So appearance changes will be slower than the divided chapter books, because for each change, KOReader still has to calculate the whole book instead of only the current chapter.
Another rare case of slowness is when the content is wrapped in a HTML table tag. KOReader has to render/draw each cell on each page turn, so if a cell (containing many paragraphs) spans 50 pages, this will make page turning quite slow. See below for the solution.
Si todo va lento:
Reasons mentioned above is generally valid if only some of your books are slow. If all of your books are slow, your problem might be device related:
Un procesador muy lento o poca memoria RAM.
Your flash memory (where your books reside) might be degrading, which is generally due to the old age of the device.
Te estás quedando sin espacio.
If you are using an Android based device, your Android OS might be interfering with the operation of KOReader or some background processes might be using your system resources.
SOLUCIONES:
Unfortunately, for bad PDF files there are not many solutions. Generally best solution with problematic PDFs and EPUBs is trying to find a better version of it. Or if another file type is available for download, like EPUB instead of PDF (or reverse) you can try that format.
Las siguientes soluciones son para los archivos EPUB y podrían exigir conocimiento avanzado:
You can set Embedded Styles to OFF in the bottom menu to see if ignoring all the document stylesheets makes it faster (of course, you'll probably lose any nice formatting, but you'll know what is the culprit).
If you have HTML and CSS knowledge, you can inspect the HTML and the CSS files directly from KOReader and judge their quality or unnecessary complexity by yourself. To do this, you can long-press on some text and choose View HTML in the popup menu.
If you have the “content wrapped in a table” problem as mentioned above in the problems section, you can add this table, tr, td { display:block; } book-specific style tweak to:
⇑ TOP MENU → → Style tweaks → Book-specific tweak
Calibre’s e-book editor can check EPUB files for problems and has tools to fix some of the problems.
EPUBCheck application can check the validity of the EPUB files and detect many types of errors. You can read an example issue, where the problem is detected with EPUBCheckhttps://github.com/koreader/koreader/issues/11268
If you are opening an issue about this problem, it is important for us to inspect the problematic file. You can share the file directly by dragging and dropping it on your GitHub message after compressing it as a ZIP file. If your book is an EPUB and you don’t want to share the file due to copyright or privacy issues, there is a plugin for Calibre named ScrambleEbook which you can access the download and instructions from this page:
This plugin will read an un-DRM'd ebook file (EPUB/KEPUB/AZW3) and create a copy of the book with its text replaced with random characters. You can share this scrambled version with us in your issue thread. Text of the book will not be readable and there won’t be any copyright violation but we can still use this file for diagnostic purposes.
Here you can see this procedure in a real issue involving a very problematic EPUB file as an example:
Probably you tapped on the STATUS BAR touch zone at the bottom of the screen. You can bring it back by tapping the same zone.
A veces mis pulsaciones se registran como una pulsación larga o pulsaciones
This can happen in cases like shaking hands or device touch screen problems. If you have this problem, you can try to increase the Tap interval. By increasing this interval, you tell KOReader to ignore quick taps at the same location.
⇑ MENÚ SUPERIOR → → Pulsaciones y gestos → Intervalo de gestos → Intervalo de pulsación
If your two consecutive taps are separated by a distance, this would not apply. So you can still quickly browse pages by tapping quickly alternatively with two fingers.
KOReader no puede escribir en la tarjeta SD
In Android devices KOReader can’t write to the external storage due to Android system restrictions. If you want to change your screenshot saving location, be careful to choose your device’s internal storage.
Ghosting and residue when turning pages
Even if KOReader is set to full refresh after every page, you may still see some ghosting/residue after turning pages. This is a limitation of e-ink screen technology and can be observed on the latest generation devices, especially while reading mixed content (text+images) documents. As a workaround, you can refresh one more time manually after turning the page to get rid of these artifacts if they bother you (short diagonal swipe gesture by default).
Sleep cover problems
Sleep covers generally use a magnet embedded in the cover which enables wake up and sleep events via triggering a sensor in your device. In some cases like misaligned magnets, weak magnets etc. this triggering can be problematic. If you are having problems with waking up your device with your cover, you can disable this feature via this menu:
⇑ TOP MENU → → Device → Ignore all sleep cover events
Problemas de sangría de texto
If you get miscentered titles, headings or separators, or unexpected text indentation, try switching the style for your document. epub.css to html5.css. This kind of problems happen because some publishers assume their books will only be read on web browser engine based readers, so they don't bother "resetting" the styles.
⇑ MENÚ SUPERIOR → → Estilo
Default HTML/EPUB (epub.css) is our book-oriented stylesheet, with text-align: justify, text-indent on P. It is better for unstyled books, and might make styled books more readable.
You can try switching to HTML5 (html5.css) if your book has indentation problems as mentioned above. This style provides a base stylesheet like web browsers do when rendering: text-align: left, no text-indent on P, spacing between P. But it doesn’t look pretty when publishers hasn’t done any styling.
Cleaning your book cover cache database
KOReader keeps a cache of your book covers to be able to show them quicker. In normal conditions this cache doesn’t get too big. If you remove lots of books or rename directories, you may want to clean up your book cover cache database to reclaim some space. You can do it from this menu:
⇑ TOP MENU (in File Browser) → → Settings → Mosaic and detailed list settings → Book info cache management
Borrar caché de archivos
Cuando está leyendo un documento PDF/DJVU, KOReader guarda una caché de la última página que ha leído. Así que cuando reabran el libro, será más rápido. Pero este caché puede crecer mucho si está usando KOReader durante mucho tiempo y leyendo muchos documentos PDF/DJVU. Estos archivos de caché se guardan en el directorio de instalación de KOReader, bajo la carpeta de caché. Para limpiar esta caché y recuperar el espacio puedes ir a:
⇑ MENÚ SUPERIOR (en el explorador de archivos ) → → Más herramientas → Opciones de desarrollador → Borrar cachés
ADVERTENCIA Limpie esta caché solo si realmente necesita este espacio. Si tiene suficiente espacio, limpiar la caché no le proporcionará ningún beneficio. En cambio, degradará el rendimiento porque su lector tendrá que volver a mostrar esas páginas.
Hacer una copia de seguridad de los ajustes de KOReader
En casos raros en los que desee hacer una copia de seguridad y restaurar su KOReader con todas sus configuraciones, puede hacer una copia de seguridad de estas carpetas y archivos bajo el directorio de instalación de KOReader. Entonces usted puede sobrescribirlos después de una instalación limpia para restaurar sus ajustes:
Carpetas:
configuración
styletweaks
Archivos:
data/cr3.ini
defaults.persistent.lua
history.lua
settings.reader.lua
Files under data/dict/ and /data/tessdata/ directories (if they exist)
INFO Your individual book settings and highlights are kept in the same directory as your books in a folder with the same name as your book. You can backup these folders separately if you wish.
