Hi,

I have a transparent layer with edges delimiting a closed area (Attached "Edge.png").
Knowing the position of one pixel within the area, I want to fill the area with a single color, in the same way someone would select the "fill color" tool and click in the area, but I want to do this from the code. (Result wanted : attached "Area filled.png")
Is there a way to do this?

Hi
You can do a flood fill, but it does not take the alpha channel into account:
