Creating own alpha channel - how?
Mar 24th, 2010, 9:24pm  
Hi,

I would like to generate my own image object by grabbing sections of the display buffer. i think this will be pretty easy.

the thing is I also need to generate an alpha channel to go with those pixels. I know how i can generate the actual mask, but can anyone give me a hint on how I would integrate that mask with my PImage object?

thanks you

PImage img = ...
PImage mask = ...

img.mask(mask);

Does that help? Check the docs for PImage.
