Hi,
I ported a JPEG decoder to plan9. It produces a
dump pic file, with 3 channels. It works well with B/W screens,
at least on ELCs. However, I'm having some problems to
display these files on color screens. They look with a lot
of red and green.
To display them I did:
$ djpeg -pic file.jpg | fb/drop # which looks awful
$ djpeg -pic file.jpg | fb/dither | fb/drop # which looks
a little better
$ djpeg -pic file.jpg | fb/quantize | fb/drop # which looks awful too
It's interesting to note that fb/dither does a better job
that quantize even though the manual says the contrary.
Well, here are some questions:
1) Does plan9 graphics system do something with 24-bit pic files?
2) what does it do?
3) Does fb/gif2pic work in any site, specially plan9.att? It does
not work in our site. It produces something similar to my pic files.
4) Is there a way to fix the pic files generated by gif2pic?
Any comment would be appreciated,
Thanks
P.D.
If anyone wants this software, in spite of what I say before,
feel free to mail me.
