Type Property

crop

A key used to specify whether to return a filter that crops the image to focus on detected features.

Declaration

static let crop: CIImageAutoAdjustmentOption

Discussion

The value associated with this key is a CFBoolean value. If true, the returned filters include an operation that crops the image around the features specified with the features option (or any features detected in the image, if that option is not present). Supply false to indicate not to return a crop filter. If you don’t specify this option, Core Image assumes its value is false.
