Hi

when i execute "convert -draw 'text 50,50 "hello"' watermark.jpg dst.jpg",it gave:Segmentation fault and no other information.

here is my config.log:

any idea?

i have fonts in /usr/share/fonts/default/Type1 and fonts.conf

Must i install ghostscript?

If i execute "identify -list font",it also gave:Segmentation fault

Can you post a stack trace so we can determine where in ImageMagick it is failing. Without it we don't have a clue why it faults.

[elvila]

sorry ,i cannot provide trace stack information. because i execute the command on a embeded device.

i think the problem is the font support.
I can convert jpeg files.

now i configure IM with option --with-fontconfig and download the fontconfig conf files and libfontconfig.so to my device.
I also download the afm and pfd files from usr\share\fonts\default\Type1 (my computer) to my device.


Do you think all these is enough for using font ?

Thanks a lot!

[elvila]

hi ,

the problem is solved.

need point out the default font path when ./configure

use --with-fontpath=/usr/share/fonts


Anyway, thanks!

Without a font path, ImageMagick should report an exception, not fault. Unfortunately we cannot reproduce the problem. We patched ImageMagick to return no fonts on our system and ImageMagick gracefully exited without generating a fault.
