#import <MPSImageMath.h> Inherits MPSImageArithmetic. Instance Methods (nonnull instancetype) - initWithDevice: Additional Inherited Members Detailed Description This depends on Metal.framework. Specifies the multiplication 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. Method Documentation - (nonnull instancetype) initWithDevice: (nonnull id< MTLDevice >) device Initialize the multiplication operator Parameters: device The device the filter will run on. Returns: A valid MPSImageMultiply object or nil, if failure. Reimplemented from MPSImageArithmetic.
