Image stretching and resizing

Question

I have a picture that I need to resize to a specific dimension and then move one of the corner to a place higher than before so the image is not rectangular anymore but some kind of polygon. Is there a library that could help me with this kind of image manipulation or does someone knows the name of this operation?

This is for a .NET application and there is an option for a six-points area also.

Anti-Grain Geometry is an interesting graphical library. There is also a .NET wrapper called CreativeDocs.NET.
