Hi,
I'm trying to convert a TrueColorMatte type tga image to a PaletteMatte
type tga image. The reason I want PaletteMatte is that i want to have a
palette with alpha value in it. So quantization of the RGBA space
instead of just the RGB space. I thought the following command should
work, but for reasons unclear to me I always get a Palette type tga:
convert in.tga -type PaletteMatte out.tga
Verbose identify output of both images below
Any ideas?
Thanks,
k|p
