I want to fill a region of an image with a given color.

But I don't want to make a loop on all the image pixels to do it.

Does there is a fast method like a growing process to fill a region ?

Thx, cjaquel

do you know already the region you want to fill?

if the region is rectengular you can use "setTo"
