MPSImageSubtract

#import <MPSImageMath.h>

Inherits MPSImageArithmetic.


(nonnull instancetype) - initWithDevice:

This depends on Metal.framework. Specifies the subtraction operator. For each pixel in the primary source image (x) and each pixel in a secondary source image (y), it applies the following function: result = ((primaryScale * x) - (secondaryScale * y)) + bias.

- (nonnull instancetype) initWithDevice: (nonnull id< MTLDevice >) device

Initialize the subtraction operator

Parameters:

device The device the filter will run on.

Returns:

A valid MPSImageSubtract object or nil, if failure.

Reimplemented from MPSImageArithmetic.
