Hi,

Is possible to apply a quadratic(or cubic)bezier curve to an image, so the resulting image will be modified to have a curve transformation in it? Something similar to barrel transformation, so for example i can give a (x,y) and imageMagick based on that ending pont creates and modifies the ...
