@type crop_focus() :: :none | :center | :entropy | :attention | :low | :high

Indicates how to determine where to crop an image to fill a target area.

• :none means the image will be reduced to fit the required bounding box and no cropping will occur.

• :center means crop from the center of the image. The central part of the image will be returned, cropped to fill the bounding box.

• :entropy uses an entropy measure.

• :attention means crop the image by looking for features likely to draw human attention.

• :low means position the crop towards the low coordinate. This means the bottom part of the image remains after the crop.

• :high means position the crop towards the high coordinate. This means the top part of the image remains after the crop.
