font file size

font file size

[zs]

Hi all,

while getting context/luatex to work, I experiment with fonts.

I play with DejaVu fonts. I found that when I use DejaVuSerif.ttf I get
what I want, but when I use DejaVuSans.ttf context produces nothing.
It seems to process document without any error message and gives no
pdf.

I made some investigation and I guess it has something to do with file
size of the font (DejaVuSerif.ttf-242KB, DejaVuSans.ttf-557KB).
Result is the same for fonts from collection with similar size.
Conversions with fontforge do not help.


Is there any limit for size of font?
Any other possible reason why?

Thanks for suggestions.

ZS

no.
Can you write down your steps for installation, so I can reproduce the
problem on my box?

1)   mkdir /usr/local/context && cp justtex.zip linuxtex.zip /usr/local/context
2)   cd  /usr/local/context && unzip justtex.zip && unzip linuxtex.zip
3)   add line to "setuptex" (TMP=~./context_tmp)
4)   cd ./tex && sh setuptex
5)   set PATH variable to have this on first place: /usr/local/context/tex/texmf-linux/bin
6)   mktexlsr&& luatools --generate && texmfstart texexec --make --all --luatex
7)   export TEXMFCACHE='/tmp' && export TEXMFCNF='/usr/local/context/tex/texmf-local/web2c' && export

8)   copy latin modern fonts from lm.zip to /usr/local/context/tex/texmf-local/fonts/
9)   luatools --generate && luatools --ini --compile --verbose cont-en

Before processing above source, copy font files from dejavu collection
(http://prdownloads.sourceforge.net/dejavu/dejavu-ttf-2.19.tar.bz2?download)

cp
DejaVuSerif.ttf /usr/local/context/tex/texmf-local/fonts/truetype/public/dejavu/djva.ttf
mktexlsr && luatools --generate
texmfstart texexec --luatex experiment.tex
... works fine

This doesn't work:
cp DejaVuSans.ttf /usr/local/context/tex/texmf-local/fonts/truetype/public/dejavu/djvb.ttf

Change font name in experiment.tex from djva to djvb.
mktexlsr && luatools --generate
texmfstart texexec --luatex experiment.tex
... gives nothing - no error, no pdf

luatex cannot load them (or even crashes) i.e. the fontforge 2 reader 
cannot read them; maybe the fonts are invalid

You mean some fonts are somewhat bad or luatex can't handle them?

Recent version of fontforge(20070723) can read DejaVuSans.ttf without
any trouble. I also tried to tranform it to *.otf using  fontforge - no
problem. Older version(200703??) worked too.

then taco needs to look into it, maybe there's a problem with the loader
