How can I auto-crop a pre-defined polygon shape from an image file?

Question

Ideally using a Python library or processing.org, I need to import an image and then crop a predefined polygon area from this image using x,y coordinates (vertices).

Thanks.

Answer 1

Try PythonMagick. Your question appears to be a cut-and-dry application of crop through specification of image geometry.

( More ImageMagick ports and documentation. )

Answer 2

Also check out PIL .

Though this is hardly library specific and almost every library should support this.
