I'm tring to achieve the following things :

- have an image in black&white, as you can see in enclosure.

- replace white by alpha channel (or other color) / and inverse : replace black by alpha channel

I'm trying to achieve this with slab and alphaglue, but it's doesnt work as expected.

If i can do this in gl, it would be perfect!

Do you have any idea ?

white-color-to-alpha

if you are on max6, you could use jit.gl.pix.

To go further, do you (or other!) it is possible to replace white or black by a variable color ?

like [matrix 4 char 1 1] to go inside ?
