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 
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
