Create region from image

dotnet drawing api: Is there a simple way to create a region from an image that has a
transparent background?

The only way I have come up with is looping through all pixels and adding
those that are not transparent.
Does anybody have a better solution?

Thanks,
Marc Selis

The iterative manner is about the only one there is.

The GDI+ FAQ has an article that is related to this problem.
