embedding fonts
Hi again list,
Thanks for your very kind replies on the other thread. I will pursue the
suggestions Glenn makes and approach other lists with xsl related questions.
For the moment, I hope you won't mind if I bother you again with another fop
question: using 0.20-5, is it possible to configure fop easily to embed all the
fonts which it is using? I tried reading the documentation for fonts[1], but
couldn't make head or tail of it. Basically, all I want to do if for fop to use
the same fonts it is using now, but embed them. I don't even know precisely what
embedding means, but it appears to be required by the printer so...
[1] http://xmlgraphics.apache.org/fop/0.20.5/fonts.html
Again, the document is http://mdke.org/ubuntu/desktopguide.pdf
Let me know if you need any more information, and sorry again for bothering you
with my rather ill-informed questions.
Matt

Actually, the FO would have been better in this case. I think you may
have specified font-style="italic" and not font-style="oblique" and
that's why the Courier font was used instead of FreeMono. So if you
change from "oblique" to "italic" in the config file, that's also fine.
It's your choice.

Sorry for spam, but I think it's resolved: I substituted "oblique" for "italic"
in the configuration file, and it appears to have worked. Does that sound right?

It occurred to me it might help for you to see the actual pdf. Here it is:
http://mdke.org/ubuntu/desktopguide-bw.pdf.
If I can provide any more information, for example the font files and so on,
please say so!

Nothing I haven't seen before in the output: http://fop.pastebin.com/679803
Was everything ok in my config file? No typos? I couldn't see any, but a second
pair of eyes won't hurt.

They were just the first fonts I selected.

I just tried the same and had no such problem with either 0.20.5 or
0.92beta. Please observe FOP's log output closely. Maybe there's another
problem. What I can see here seems fine.
Just curious: Why are you substituting the base 14 fonts with FreeFonts
in the first place? Do you expect some additional characters not
supported by the base14 fonts?

Yeah, you're right, acrobat shows it fine. The bug is
https://bugs.freedesktop.org/show_bug.cgi?id=6728
One last question on embedding fonts: I've used only Serif and Monospace in the
document, and have successfully embedded everything except for Monospace
Oblique. It has used a non-embedded font for that. Here are the relevant
sections in my config file, did I miss something?
<font metrics-file="../libs/pdf/fonts/FreeMonoOblique-ttf.xml" kerning="yes"
embed-file="/usr/share/fonts/truetype/freefont/FreeMonoOblique.ttf">
<font-triplet name="monospace" style="oblique" weight="normal"/>
</font>
<font metrics-file="../libs/pdf/fonts/FreeMonoBoldOblique-ttf.xml"
kerning="yes"
embed-file="/usr/share/fonts/truetype/freefont/FreeMonoBoldOblique.ttf">
<font-triplet name="monospace" style="oblique" weight="bold"/>
</font>
Perhaps I was wrong to put style="oblique"?

Those, I can see, too. You can ignore them. FOP 0.92beta doesn't issue a
warning on these anymore.

Hmm, Acrobat Reader displays the PDF just fine. GhostScript fails, too.
Without better error messages from these programs I don't know what
could be wrong. Maybe these are bugs in GhostScript and Evince.

I'm making slow progress. I've added the fonts to my configuration file[1] and
told fop to use it. I use "<xsl:param name="body.font.family"
select="'Serif'"/>" in my xsl. When fop converts the fo to pdf, it looks like it
completes as before.
[1] CONFIG: http://fop.pastebin.com/678850
However, right at the end I get these errors:
[ERROR] TrueType warning: Can't find prep table
[ERROR] TrueType warning: Can't find prep table
[ERROR] TrueType warning: Can't find prep table
But the pdf is created ok. Then I try to open it in my pdf viewer (Evince) the
fonts don't show up. In my terminal, I see lots of these errors:
Error: Couldn't create a font for '1E14e6FreeSerif,Medium'
Error: Couldn't create a font for '2E152dFreeSerif,Italic'
Any ideas?

Looks like you have a good share of bad luck with FOP. :-( You've
stumbled upon a bug in TTFReader we recently fixed. Please use the
TTFReader coming with FOP 0.92beta to create the font metric files. The
generated files should also work with FOP 0.20.5.
Please note that the classpath for the command-line of TTFReader is
slightly different:

Right, i'm trying to use TTFReader now, as specified on the fonts documentation
page. However, it shows an error. I'm using Ubuntu, java jdk 1.5 and fop 0.20-5
ERROR: http://fop.pastebin.com/678687
It's possible that I've misunderstood the command I should be running. Hope you

Thanks for this explanation! I will try and do this, although the "creating font
metric files" bit sounds rather difficult. I'll give it my best shot!

That's fine: it makes sense now. I just wondered whether it was possible to do
it automatically for all fonts used by fop when creating the pdf. No problem!

"Embedding" means that the font is included in the PDF file. Otherwise,
the font is only referenced and is required to be present on the viewer
or printer. If it's not present on the receiving side, the document
can't print correctly. If you want to embed all fonts, you have to
create font metric files using PFMReader or TTFReader for each one and
create the correct font triples in the configuration file. As soon as
you specify a embed-file attribute (embed-url in 0.91 and later), the
font will be embedded in the generated file. ATM, there is no easy way.
I may get easier later this year when we have an improved font subsystem
but ATM, it's a lot of manual work.
If that doesn't help you on your way, please tell us exactly what on the
fonts.html page is unclear to you.
