Can't blit_rect_mask

You might have to use a shader.

What is your end goal? Is it possible to preprocess the images? For example, using get_pixel() / set_pixel() on setup and then cache the textures? Or do you need to do this in real time?

Actually, I don't need it in realtime. I can pre-process it. But I'm doing lots of stuff, so I need all my processes to be as fast as possible, as it adds up.
I guess I will be able to make it a bit faster by using the values of any of the channels of the mask as lookup table, to speed things a bit.

So I would recommend using the image methods get_pixel/set_pixel. They are slow for real-time, but not that slow if you only do it sometimes on load. I think I did a 720P image and it was about half a second, that's about a million pixels. Then save it as a PNG image. That way you only have to recalculate if the source images have changed.

I will do that. Of course, I can only try it tonight, after my day job 😉

rui_mac But I need to make it for 7 * 128 * 512 pixels.

Watch out, in markdown you make text strings italic if you surround them with asterisks without spaces. 😉
