ImageForwardTransformation

ImageForwardTransformation[image, f] gives an image where each pixel at position f[{x, y}] corresponds to position {x, y} in the input image.

ImageForwardTransformation[image, f, size] gives an image of the specified size.

Examples

Apply a swirl transformation:

img = ExampleData[{"TestImage", "Lena"}];
ImageForwardTransformation[img, {#[[1]] + 0.1 #[[2]], #[[2]]} &]

Polar transformation:

ImageForwardTransformation[img, {Norm[#], ArcTan @@ #} &, {256, 256}]
