I'm trying to convert some color-indexed RGB images for a game I'm working on. I have a utility I wrote that generates the data bytes and color tables in a way I can use, but the color conversion has to be done by hand and my eyesight isn't up to the task.
I was hoping to have some way to convert, if only approximately, the RGB triples to the GTIA color codes. I've stumbled across some of those crazy cylinder formulas, but the principles involved are a complete mystery to me.
Wow, I even posted in that thread. I don't remember that at all. I'll check this out later. Unfortunately, I develop on a Linux machine and this isn't running with Wine. The next time I'm on Windows I'll see if this can help me, thanks.
