Crop an image to the specified boundary
PhImage_t *PiCropImage( PhImage_t *image, PhRect_t const *bounds, int flags );
This function crops a Photon image. It allocates space for the resulting image, leaving the original image untouched.
The image argument is a pointer to a PhImage_t structure that defines the image to be cropped, while the bounds argument points to a PhRect_t structure specifying the rectangle within the image to keep.
The flags argument dictates special behavior of the cropping process and can take on the following values:
|If you set the Pi_FREE flag, the function will free the old image by setting all its release flags and calling PhReleaseImage() on it.|
A pointer to the new image on success, or NULL if an error occurred.
