View Full Version : Scale and bias for alpha

06-17-2003, 08:36 AM
Is there are an option to use some kind of bias for alpha channel. I want to blend two images based on alpha data of second image but also need to have adjustable threshold. I.e. ones i want second image become fully transparent at 80% of transparency and smoothly change that value to 60% or 100%... and the same with opaque part...
