How did you manage opacity? Or rather, color blending?

How did you manage opacity? Or rather, color blending?

Color blending is pretty simple, using linear interpolation, or "lerp" for short. If you want 80% of one color and 20% of another, for each individual RGB component, you'd simply do the following:

R=0.8*R0 + 0.2*R1

For alpha blending, where 0% alpha should make it the first color and 100% alpha should make it the second color, the formula becomes:

R=(1-A)*R0 + A*R1

And to extend that to alpha having a range of 0 to 255, rather than 0% to 100%:

R=(1-A/255)*R0 + A/255*R1

You can see this used in my own anti-aliased line library.

I'm considering restarting the DEFY Paint project now, with the DEFY 2.0 project.
