Creating a CRgn from a given point

I want to perform a flood fill operation with a given point. But first I want to create a region by detecting the outline and make some modifications.

Can someone let me know a good flood fill source code/algorithm for irregular shapes, which can also help me create a CRgn object of the shape to be filed.

So you are trying to generate a CRgn from some arbitrary existing shapes and a starting point.

This, of course, isn't required for doing the flood fill.  I assume that you want the CRgn for other purposes.

A flood fill algorithm can be easily adapted to give you the points on the boundary.  The, once you have the points, you should be able to generate a region.

Is this what you want???

I can't understand well.
MFC gives you the ExtFloodFill to fill a clipping region.
You can create a clipping region with the CRgn class members.
What else do you need? Why do you need to perform manually the fill?
