Font discrimination

[roger64]

Hi

1. Discrimination
I use a main embedded font (Linux Libertine O) declared in the body. However for some styles (book index for example) I also use a dedicated smallcap font (Linux Libertine Capitals) declared for some styles.

For some reason, the Calibre editor does not accept to subset it and discard it as "unused". This font provide smallcaps and only smallcaps.

@font-face {
font-family:'Linux Libertine Capitals';
font-weight: normal;
font-style: normal;
src:url(../styles/LinLibertine_aS.ttf) format('truetype');
}

Two styles using it:

p.smcpindex {margin-left:1.0cm;margin-right:0.499cm;margin-top:0.0cm;margin-bottom:0.101cm;border:none;padding:0;background-color:transparent;text-indent:-0.499cm;text-align:justify;font-family:'Linux Libertine Capitals';}
h2 {page-break-before:always;margin-left:0.0cm;margin-right:0.0cm;margin-top:1.499cm;margin-bottom:1.0cm;border:none;padding:0.0cm;text-indent:0.0cm;text-align:center;font-family:'Linux Libertine Capitals';font-style:normal;font-variant:normal;font-weight:normal;text-decoration:none;text-transform:none;clear:left}

Question: what must I do to force the Calibre editor to take it into account (the Inspector can see it)?

2. Another thing is a constant complaint about mime-type for ttf fonts. What exactly should I write and where to get rid of this warning message?

1. You need to provide an complete example book

2. The warning about font mimetypes has all the information needed to fix the problem and even a link to fix it automatically

Thnaks for your reply

I will try to provide you with an example book asap.

1 discrimination

I cannot attach even a zip file to MobileRead, so there is the link to essai.epub on Mega
https://mega.co.nz/#!dJcGyTzJ!XmL6ug...2rtkGLlfEtEnn8

It includes eight fonts,
- four from the main otf family Linux Libertine (only the regular one is used for the body) and
- four ttf fonts (only Linux Libertine Capitals is used for two styles - h2 and smcpcorps).

If I ask to subset fonts, Calibre discards the ttf one even if it is declared. Normally Calibre should keep and subset one otf (Regular) and one ttf (Capitals) . It should discard the others.

2. Error message
This is the message I read many times for many months.

Le fichier OEBPS/styles/linlibertine_c-4.0.4ro-webfont.ttf a son type MIME spécifié à application/x-font-ttf dans le fichier OPF. Le type MIME recommandé pour les fichiers avec l'extension "ttf" est application/x-font-truetype. Vous devriez changer soit l'extension du fichier soit le type MIME spécifié dans le fichier OPF.

I know that Calibre can correct automatically this ttf and true-type question and I use it, but I do not understand how to avoid it in the first place. Hopefully, there are four ttf fonts, maybe someone will show me how to achieve this. I use Linux Mint 64 bits.

[kovidgoyal]

Like the message says, the correct mimetype for your font file is

application/x-font-truetype

not

application/x-font-ttf

If you want to avoid that errors, make sure that is the media type set in the OPF file for the font.

[kovidgoyal]

And your embedding problems are caused by format(truetype) in in the @font-face rule. Remove that and you should be fine.

I dare not say for how long I have been doing this way

anyway now everything is perfectly fine and I very much!
