RGB Transparentcy? Or lack there of.

[Gooie]

Sorry for all the help topics, but I ran in to a problem today, while working with GIFs and RGB.SetColour.

All I did, was draw a GIF image with transparency and it worked fine. But once I added RGB.SetColour the transparent parts were white. I didn't even draw anything with that color yet. I asked my teacher about it and she said she was stumped. So, is this a problem with Turing or me being an idiot?

In such a case, it helps to set up little test-case experiments -- try to reproduce the effect with the least code possible. Take out everything but the essentials, and run it in a new file. This is the base case that we will study.

Ideally you will have a tiny program that draws an image as expected. Then when you add a single line of code (RGB.SetColour), the transparency breaks -- then you will know this is the case.

If so, I suspect that that RGB.Set might be messing with Turing's default pallet of colours, but it's just a guess.

Feel free to publish such case studies in the Tutorials -- it's a good learning experience to figure such things out.
