Re: [Sgems-devel] Color Table fo rimages

[nico r. <nic...@gm...>]

Hi Dave,

I can't remember why I limited the number of colors to 256 in sgems...
So, you have a colormap file with more than 256 entries? You could
always sample the colormap to reduce the number of colors to 256,
especially if the colors follow a gradient.
