I am not sure were feature requests should be placed, but I am going with here.
It would be nice to have the Smart Fill work on bitmaps like Inkscape does. All in all it is a small thing I suppose, but I am throwing it out there.
Feature and requests are HERE
PhotoPaint "Fill Tool" have tolerances set to 20+/- or so will do this as will the "Replace Color" command in PP
Eggzample....
Ah, I seldom open PP, but that is good to know. However, the idea was to create a new vector object. It's like a quick partial trace bitmap. Inkscape is a Vector editor. It seems that Draw could do this as it has a trace bitmap engine in place.
It is a small thing. One can always just trace the whole bitmap and take it from there. Just a thought.
AND, where do you think the coal for your electricity comes from for you city folk G E O R G E?
I think this feature was there way back in the first versions of Draw, say 20 years ago.It was kind of a quick trace tool which created a vector object from an area with a specific color when you clicked on it, pretty much the same as you describe.Maybe time to add it back? Shouldn't be that hard to do I guess.
