Would they? People post textures in JPEG form often on this forum, and they seem sharp enough depending on the compression settings used.
Some games, like Second Life, use Jpeg2000 compression, which squeezes even more quality out of the same file size (or gives a smaller file for the same quality). The downside is that it's not widely adopted, and you may need to include a library that can read it.
Sorry, don't noticed this post until now.
I tried out what is possible.
When I use the maximum quality the result is that: ( 3 megs big)
I used the colorkey 255, 000, 255 (Magenta). As result you see colorkeying 255, 000, 254!?!. What you see in magente is 255, 000, 255 ! the rest is gone by the jpg format.
It is no problem for mee to turn the magenta color into black ->no one will see the wrong pixelcolor anymore, but the collisiondetection is gone. You see the the little
playership riding on a magenta pixel.
Again, hope you know what i mean. Its not easy for me to explain it all in english.
