Embedded font, own font: how?

[bverspeiser]

I tried to embed LexiaDaMa into a book with the new function in book convert. I put the ttfs into my ~/.fonts, into the /usr/share/fonts/... and into /opt/calibre/resources/fonts, but with every try I get the message

ValueError: No embeddable fonts found for family: u'Lexia DaMa'

Do I need to do some additional configuration in calibre to add the font? Linux/Debian/Wheezy with the sudo python... installation 0.9.4. The system tools/openoffice can see the fonts from ~/.fonts and the system directory.

[kovidgoyal]

calbre uses fontconfig to get the list of fonts. If the font is visible to fontconfig, it should be visible to calibre as well.

[kovidgoyal]

Another thing, the font family you choose has to have a "normal" or "regular" font face. I think Lexia DaMa has only a bold font face, I'll make the error message a little clearer about that in the next release.

[bverspeiser]

Ah, I see. Lexia DaMa has a "Medium" style only:

/usr/share/fonts/truetype/tt-lexiadama/LexiaDaMa.ttf: Lexia DaMa:style=Medium
/usr/share/fonts/truetype/tt-lexiadama/LexiaDaMa-Bold.ttf: Lexia DaMa:style=Bold
/usr/share/fonts/truetype/tt-lexiadama/LexiaDaMa-BoldItalic.ttf: Lexia DaMa:style=Bold Italic
/usr/share/fonts/truetype/tt-lexiadama/LexiaDaMa-Italic.ttf: Lexia DaMa:style=Italic

Is there a technical difference between "normal" and "Medium" (like "normal" is nothing or no style?)

[kovidgoyal]

Medium should be mapped to normal. What does the following return:

calibre-debug -c "from calibre.utils.fonts import fontconfig; print fontconfig.fonts_for_family('Lexia DaMa').keys()"

[kovidgoyal]

Never mind, I was wrong, medium is not mapped to normal. http://cgit.freedesktop.org/fontconf...tconfig.h#n126
