Grabbing a part of an image

[holographl]

I'm trying to allow the user choose part of an existing image and then copy that area to a separate bitmap file. The area may be any shape.

I see the clippath command for a canvas but I dont seem to see that you can do anything with what was clipped. It would be great if you could save that as a file or something.

Has anyone done something like this before and can give me an idea?

thanks.

1. Create a mutable bitmap image with the same size of the original image.
2. Draw on this bitmap with Canvas.Initialize2
3. Call Canvas.ClipPath to only draw on this specific shape.
4. Draw the original bitmap to the Canvas.
5. Save the new bitmap to a file.
