Hi,
do you know the overlay blending funktion in adobe's photoshop.
I want to use this for my mobile app. , to decrease the memory wasting.

Does anybody know the calculations between it for the corresponding pixels?

I first thought it would be R G B*Alpha ) + (R G B  * Alpha), but i was wrong Smiley

example: a black line 0, 0, 0
freshes up a green line  73, 255,97
to a  0, 255, 0

i want to use a kind of watermark in a menu

and scrollable lines.... so ... i can not store the photoshop result to an imagefile.

sincerly

me
