I also found that pix_record not only gets the colors wrong, but seems
to rotate the picture 90 degrees and reverse it as well. (The abstract
nature of the piece is why that wasn't obvious immediately.) But how
can it be that pix_record does this, and especially that people haven't
noticed and complained? Or fixed, those who know how? (Not me, I'm
afraid.) Incompatibility between how the various video cards label
screen directions and RGB colors?
in this i would suggest reporting the full version of Gem and where you
obtained it from. i couldn't find anything about the version of Gem
_you_ are actually using.
rotating the picture by 90° is _very_ unusual. did you mean 180°?
