- "width": An integer representing the desired width in pixels.
- "height": An integer representing the desired height in pixels.
- "anchor": A string describing where the crop should originate in the form of "XOFFSET-YOFFSET". XOFFSET is either a number of pixels or "left", "center", "right" and YOFFSET is either a number of pixels or "top", "center", "bottom".
