[SOLVED!] With Renpy theme, any way to change/use multiple colors for Button using tags?

[OhWee]

@anne O'nymous

Thank you for that example of using the AlphaMask with a background color (Solid)!

sooooo all the im.MatrixColor stuff could be avoided by just using an AlphaMask X_x and it looks so simple... hmmmmm

My only concern with that might be that the mask might have more CPU overhead than changing the color. I don't really know though, just a theory...

Both are quite useful though, now that we have decent coding examples!

You're welcome.

It's the opposite. im.matrix will perform matrix calculations over the image, while the alpha mask will just combine the color of two pixels (basically two divisions then an addition). Therefore, the alpha mask rely on natural instructions of the CPU, while the matrix calculations have to simulate most of its operations, breaking them down to the four primary operators (and so natural instructions).
Anyway, nowadays both alpha mask and matrix calculations are basic operations for pictures. So, like Ren'py rely on openGL/directX, which themselves rely on the GPU, it's probably atomic (or not so far) because the GPU probably have dedicated instructions for that.
