The crop mode defines how the image should be scaled and aligned when the
fit=crop parameter is set. The
height parameters set both the crop dimensions and initial resize of the image. This crop mode ensures the image is always cropped to the exact dimensions specified, and results some of the original image being cut off.
Valid values for the crop position are
right. If no value is explicitly set, the default behavior is to crop from the center of the image.
Crop from center
Crop from top
Crop from right
Crop from bottom
