MPSImageReduceUnary(3) MetalPerformanceShaders.framework MPSImageReduceUnary(3) NAME
MPSImageReduceUnary SYNOPSIS
#import <MPSImageReduce.h> Inherits MPSUnaryImageKernel. Inherited by MPSImageReduceColumnMax, MPSImageReduceColumnMean, MPSImageReduceColumnMin, MPSImageReduceColumnSum, MPSImageReduceRowMax, MPSImageReduceRowMean, MPSImageReduceRowMin, and MPSImageReduceRowSum. Instance Methods (nonnull instancetype) - initWithDevice: Properties MTLRegion clipRectSource Additional Inherited Members Detailed Description MPSImageReduce.h MetalPerformanceShaders Copyright: Copyright (c) 2017 Apple Inc. All rights reserved. Reduction filters for MetalPerformanceShaders The MPSImageReduce performs a reduction operation The reduction operations supported are: o Reduce row min o Reduce column min o Reduce row max o Reduce column max o Reduce row mean o Reduce column mean o Reduce row sum o Reduce column sum Method Documentation - (nonnull instancetype) initWithDevice: (nonnull id< MTLDevice >) device Standard init with default properties per filter type Parameters: device The device that the filter will be used on. May not be NULL. Returns: a pointer to the newly initialized object. This will fail, returning nil if the device is not supported. Devices must be MTLFeatureSet_iOS_GPUFamily2_v1 or later. Reimplemented from MPSUnaryImageKernel. Reimplemented in MPSImageReduceRowMin, MPSImageReduceColumnMin, MPSImageReduceRowMax, MPSImageReduceColumnMax, MPSImageReduceRowMean, MPSImageReduceColumnMean, MPSImageReduceRowSum, and MPSImageReduceColumnSum. Property Documentation - clipRectSource [read], [write], [nonatomic], [assign] The source rectangle to use when reading data. A MTLRegion that indicates which part of the source to read. If the clipRectSource does not lie completely within the source image, the intersection of the image bounds and clipRectSource will be used. The clipRectSource replaces the MPSUnaryImageKernel offset parameter for this filter. The latter is ignored. Default: MPSRectNoClip, use the entire source texture. The clipRect specified in MPSUnaryImageKernel is used to control the origin in the destination texture where the min, max values are written. The clipRect.width must be >=2. The clipRect.height must be >= 1. Author Generated automatically by Doxygen for MetalPerformanceShaders.framework from the source code.
