I've written an image loader for evas that can load pbm, pgm, ppm. It
supports P1, P2, P3, P4, P5, P6. For P5 and P6 it also supports the
2-byte format. Unfortunately I haven't seen that there is a pnm loader
for imlib2, when I started to write it. And when I saw the imlib2
loader, I've already written the most parts of my loader. Compared to
the imlib2 loader my loader is very lenient, supports 2-byte binary
format and imho is easier to understand. Therefor the imlib2 code might
be a bit faster. I haven't measured it tho. And the felt load time is
almost equal.
I named the loader pmaps, but if you prefer I can rename it to pnm.
The attached diff only adds the loader to evas. The pmaps directory can
be found here:
http://mowem.de/evas/pmaps.tar.gz
or if you just want to scroll through the c file:
http://phpfi.com/296415
If you like it, I'll commit it.
