Programmatically to a Given Size...
Crop a 256×256×110 image to 128×256×110 pixels, revealing the internal structure:

- A cropping fraction of –1 means crop on the negative axis side, 0 means crop equally on both sides and 1 means crop on the positive axis side.
Programmatically, Trimming a Given Amount...
Trim 128 pixels from the positive x axis side using ImagePad with a negative value:
