Any ways to mask or crop images dynamically?

Just wondering, because the only way to mask, clip, or crop images that I know or involves the TEXTURES lump.

Depends what you're trying to do. Maybe a custom shader?

You might be interested in canvases and the related DrawTexture function (it's the same as for drawing on screen) that allows shifting, clipping, scaling, and rotating a texture you draw on it through the tags argument pairs.

Wow, didn't realize that was possible. Would you take a look at this thread? It's something I solved with a custom shader but maybe you can tell me if there is another/better way?

That does look interesting, and I think that will work for what I'm trying to do. Thanks!
