Is there any library that uses a content scaling algorithm to resize images? Or built-in methods to achieve it?
This is the same as in Photoshop CS4 + ...
Mike Swanson has made many useful graphical tools, including a C # implementation of a scalable content called SEAMonster
Have you tried using Photoshop. maybe some of the APIs etc.
Perhaps you can use this fluid scaling or resynthesizer in the same way gd-sharp provides a C # interface for the externed gd library. Then us it is semi-iterative.
