Trim Image

Trims the image to remove a uniform border around the image. This operation must be set for the other trim parameters to work, and it will change the size of the image.

There are 2 available values: auto and color.

• When the trim parameter is set to auto, the image is trimmed automatically based on the border color. You can adjust the tolerance using trim-md and trim-sd.
• When the trim parameter is set to color, the image will trim away the color specified by trim-color, as long as it is within the trim-tol threshold.
