Portable Calibre Viewer and custom fonts

[Dfaure]

Hi,

I'm using a Portable Calibre for both storing and reading books.

Looking at the application's resource directory, I found a folder with the Liberation font.

I was wondering how I could use my own font set for reading without being obliged to install it in the hosting system?

The font in the viewer is only used if the book you are vieweing has not specified any fonts of its own. The best way to ensure you get the fonts you want is to convert the book, embedding the font during conversion.

That's fair.

I just wanted to use the calibre viewer in the same way I could do with a physical e-book reader.

Thanks to the user stylesheet parameter I can specify my own fonts for the ebook rendering, but these should be registered in the hosting system.

How could I do that without being obliged to install fonts on each computer I could use?

Open the e-book viewer go to "preferences" then "User_stylesheet" then use the following code with your font.

body {
  font-family: "MyFont", serif;
}
@font-face {
  font-family : MyFont;
  font-weight : normal;
  font-style: normal;
  src : url(MyFont.otf);

@font-face {
  font-family : MyFontBold;
  font-weight : bold;
  font-style: normal;
  src : url(MyFontBold.otf);
}
@font-face {
  font-family : MyFontItalic;
  font-weight : normal;
  font-style: italic;
  src : url(MyFontItalic.otf);
}
@font-face {
  font-family : MyFontBoldItalic;
  font-weight : normal;
  font-style: BoldItalic;
  src : url(MyFontBoldItalic.otf);
}

Replace the Myfont... with the name and path of the font you are using.

example src : url(...\calibre\resources\fonts\MyFontBoldItalic.o tf)

Copy the font you would like to use into the font folder of the calibre portable.

That should work do not have a calibre portable to test.

Well, I made some tests and even if took some time to report them here, once again, I found that Calibre is already handling this gracefully:

In the application settings folder, ie. either "Calibre Portable\Calibre Settings" on a portable instance or the equivalent one on regular installation ("%USERPROFILE%\AppData\Roaming\calibre"), just look for a "fonts" folder (or create one if needed).

Then, simply put your font files directly into it since sub-folder don't seem to be handled there, leading to something like:

Calibre Settings
 +-- fonts
      +-- my_font_a.ttf
      +-- my_font-Bold.ttf
      +-- my_font-BoldItalic.ttf
      +-- my_font-Italic.ttf
      +-- ...

At Calibre's e-book viewer start, the locally copied fonts are made available and may be selected in the Preferences/General/Font options like the system-wide default ones.
