Should the blend tool use premultiplied alpha for custom gradients?
Make a custom gradient that is white on one end and transparent on the
other. (Go on, use the RGBA 0, 0, 0, 0 option provided on the menu.)
Now use it with the blend tool on a white canvas. The result is a gray
band.
In comparison, with the foreground set to white, use the blend tool's
"FG to Transparent" on a white canvas. Isn't that better?
So, I'd call the lack of premultiplied alpha for custom gradients a bug.
But I seem to recall a recent debate about when it was and wasn't
appropriate for gimp to use premultiplied alpha, so I figured I'd ask
first.
Cheers,
- Kevin
