We are about to switch to a new forum software. Until then we have removed the registration on this forum.
We have 32bits for the colors. So for ARGB we have 8 bits for each channel.
So in theory I should be able to make a color with for example.
red 255 green 0 blue 0 alpha 0
So a full red color that you can't see cause it's totally transparent... In practice it becomes 0, 0, 0, 0. Which makes sense cause it's a lot faster to draw the result.
Then a bit further. If we have a color like:
vec4(1, 0, 0, 0.5);
Then in processing we have 128,0,0,128.
I would like that to be 256,0,0,128. Is this possible in any way? The reason is I use bitflags to set data. And as it seems now, it's not possible to use the alpha channel cause they mess up all the bitflags in the RGB area.
Hope someone can follow me :) (I want to make a tutorial about it soon for the processing site cause I think there can be done really neat things with it).
