I'm trying to load an eps into an gdk_imlib image. When gs converts
the file to an image, it outputs a file that looks like:
P5
# Image generated by Aladdin Ghostscript (device=pnmraw)
139 117
255
<data>
Looking at this with od:
0000000 P 5 \n # I m a g e g e n e r
0000020 a t e d b y A l a d d i n
0000040 G h o s t s c r i p t ( d e v
0000060 i c e = p n m r a w ) \n \n 1 3 9
0000100 1 1 7 \n 2 5 5 \n ÿ ÿ w \0 \0 \0 \0
Unfortunately, imlib barfs on the blank line after the comment (see
/mit/source/third/imlib/gdk_imlib/io-ppm.c around line 50).
It's unclear whether gs is creating a bogus p*m or whether imlib is
barfing on a valid p*m. Most likely this is a problem with both
programs. Consenus on zephyr appears to be that this is imlib's fault
and the p*m is valid, but this is still speculation.
A quick fix would be to change line 50 to read:
if (s[0] != '#' && s[0] != '\n')
