Talk:Color quantization

file format?

Perhaps this task should use the PPM file format, since we know that a lot of languages here support it? (Write ppm file) Either that, or perhaps we should first have tasks to read and write .PNG files. That said, I think the TGA file format would be much simpler to implement support for, than PNG and still supports indexed color formats. That said PPM could work for this task, though without any compression from the color reduction. Another alternative might be to simply list the reduced color set and perhaps some associated statistics. --Rdm 19:55, 12 August 2011 (UTC)

I don't care. I didn't even ask for the resulting image to be written, so any format you are comfortible with is fine by me, the only required thing is the image content, which is the frog picture. Task requires outputing the colors reduced to, your alternative. Of course it wouldn't hurt if reduced color image is posted, though. --Ledrug 20:11, 12 August 2011 (UTC)
