Class MPSImageAreaMax

  • All Implemented Interfaces:
    NSCoding, NSCopying, NSSecureCoding, NSObject
    Direct Known Subclasses:
    MPSImageAreaMin
    public class MPSImageAreaMax
extends MPSUnaryImageKernel
    MPSImageAreaMax The MPSImageAreaMax kernel finds the maximum pixel value in a rectangular region centered around each pixel in the source image. If there are multiple channels in the source image, each channel is processed independently. The edgeMode property is assumed to always be MPSImageEdgeModeClamp for this filter.

      • initWithDevice

        public MPSImageAreaMax initWithDevice​(java.lang.Object device)
        Description copied from class: MPSUnaryImageKernel
        Standard init with default properties per filter type
        Overrides:
        initWithDevice in class MPSUnaryImageKernel
        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.

        public MPSImageAreaMax initWithDeviceKernelWidthKernelHeight​(MTLDevice device,

                                                             long kernelHeight)
        Set the kernel height and width
        Parameters:
        device - The device the filter will run on
        kernelWidth - The width of the kernel. Must be an odd number.
        kernelHeight - The height of the kernel. Must be an odd number.

      • kernelHeight

        public long kernelHeight()
        [@property] kernelHeight The height of the filter window. Must be an odd number.

      • kernelWidth

        public long kernelWidth()
        [@property] kernelWidth The width of the filter window. Must be an odd number.

      • initWithCoderDevice

        public MPSImageAreaMax initWithCoderDevice​(NSCoder aDecoder,
                                           java.lang.Object 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.
        Overrides:
        initWithCoderDevice in class MPSUnaryImageKernel
        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.

      • supportsSecureCoding

        public static boolean supportsSecureCoding()

      • _supportsSecureCoding

        public boolean _supportsSecureCoding()
        Description copied from interface: NSSecureCoding
        This property must return YES on all classes that allow secure coding. Subclasses of classes that adopt NSSecureCoding and override initWithCoder: must also override this method and return YES. The Secure Coding Guide should be consulted when writing methods that decode data.
        Specified by:
        _supportsSecureCoding in interface NSSecureCoding
        Overrides:
        _supportsSecureCoding in class MPSUnaryImageKernel
