MPSImageStatisticsMinAndMax(3)
NAME
MPSImageStatisticsMinAndMax
SYNOPSIS
#import <MPSImageStatistics.h> Inherits MPSUnaryImageKernel. Instance Methods (nonnull instancetype) - initWithDevice: (nullable instancetype) - initWithCoder:device: Properties MTLRegion clipRectSource Additional Inherited Members
Detailed Description
MPSImageStatistics.h MetalPerformanceShaders.framework Copyright: Copyright (c) 2016 Apple Inc. All rights reserved. MetalPerformanceShaders image statistics filters The MPSImageStatisticsMinAndMax computes the minimum and maximum pixel values for a given region of an image. The min and max values are written to the destination image at the following pixel locations: o min value is written at pixel location (0, 0) o max value is written at pixel location (1, 0)
Method Documentation
- (nullable instancetype) initWithCoder: (NSCoder *__nonnull) aDecoder(nonnull id< MTLDevice >) device NSSecureCoding compatability While the standard NSSecureCoding/NSCoding method -initWithCoder: should work, since the file can't know which device your data is allocated on, we have to guess and may guess incorrectly. To avoid that problem, use initWithCoder:device instead. Parameters: aDecoder The NSCoder subclass with your serialized MPSKernel device The MTLDevice on which to make the MPSKernel Returns: A new MPSKernel object, or nil if failure. Reimplemented from MPSUnaryImageKernel. - (nonnull instancetype) initWithDevice: (nonnull id< MTLDevice >) device Specifies information to apply the statistics min-max operation on an image. Parameters: device The device the filter will run on Returns: A valid MPSImageStatisticsMinAndMax object or nil, if failure. Reimplemented from MPSUnaryImageKernel.
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.
