I'm a complete beginner with Processing and have managed to find my way pretty far but this last problem seems just impossible to find a solution for.
I'm working with three separate monochrome images (one in cyan, one in magenta and one in yellow - all with white backgrounds) that I want to layer on top of each other in different positions and use something like a MULTIPLY blend mode to be able to see them all at the same time. I've found a way to move them in relation to each other but when I try to combine it with
blend (0, 0, 600, 424, 0, 0, 600, 424, MULTIPLY);
it doesn't work any more.
As you can see in my code below I've also found the option to reduce the tint but it makes the images extremely pale.
