I'll send some of both for your entertainment, but I think this problem is as old as the code for the palette. The image looks fine in PSP, but the squares get very rectangular in fractint. Without the borders, fractint's own palette would be similar (but not mirrored at every other row).
Oh, and BTW, maxiter is potentially irrelevant with ATAN. About twenty moons ago, I jenerated something that only did one [iteration] and still ended up with many colours.
Ah, I see. The code for atan looks like this:
coloriter = (long)fabs(atan2(new.y,new.x)*180.0/PI);
I'll change it to:
coloriter = (long)fabs(atan2(new.y,new.x)*colors/PI);
I'll have to put in some code for backwards compatibility, so it won't quite look like that. Thanks for pointing out the problem.
Thanks for taking orders like you had children to avoid. I might look for an arbitrary number of colours from ATAN, but for the most part, I think darkening or lightening the imaj in PSP will do. The important problem, IMV, is the rounding from 24bits to eighteen. I don't really like using a graymap that isn't exactly gray, although it tells me that there's a hack for getting 768 levels of gray under hicolor and truecolor (assuming gamma=1) and that some users might appreciate GIFs that accomodate EGA. They're using computers that are more than ten years old, so I appreciate their dedication to alleviating the burden on our landfills. I think this might be the source of problems for stereograms, too. Or it might mask the problem. Maybe I should try 1bit stereograms. For printing, there is physically no other kind, and I'm kinda curious as to whether that means I must dither.
BTW, if you like Linux, but you don't hav twelve days to download three CDs over POTS, then you might look at Linux Format magazine. It's a lot messier than their mandrakelinux.com/en/92errata.php3 paje would tell you, but it's still a lot easier to waste more than 64meg of RAM under Linux than under DOS.
Already use a Mandrake distribution. Planning to switch to SUSE.
Got any particular reason? Some inviting things are on my DVD, but I don't think I'll ever get around to using everything that I installed. (And one reason I'm in AIX over DOS now, is because the last time I made sndconfig work, I used DOS to disable my card, first). Debian seems to be the one for network-only distribution. And there's an Edmonton based distribution, MaxOS, that people I've met might run.
