This command has the following features:
RotateCommandFlags.Resample and RotateCommandFlags.Bicubic can be combined with RotateCommandFlags.Resize, but they can not be combined with each other.
If RotateCommandFlags.Resize is set, then the image is resized. Otherwise, the image is cropped.
Interpolation can be done while rotating certain images. This produces superior output, eliminating the jaggedness occurring when rotating images at angles that are not multiples of 90. (ie when RotateCommand.Angle is not a multiple of 9000).
The only images that are interpolated are:
For all other images, RotateCommand ignores the resampling flags and the rotate is performed without interpolation.
For more information, refer to Processing an Image.
This example will load an image, rotate it by 45 degrees and then save it back to disk
