Use this property to tag cases where premultiplied results are required. If MPSPixelAlpha_AlphaIsOne is used, the alpha channel will be set to 1. Default: MPSPixelAlpha_AlphaIsOne

      • initWithDevice

        public MPSImageConversion 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 MPSImageConversion initWithDeviceSrcAlphaDestAlphaBackgroundColorConversionInfo​(MTLDevice device,

        Create a converter that can convert texture colorspace, alpha and texture format Create a converter that can convert texture colorspace, alpha and MTLPixelFormat. Optimized cases exist for NULL color space converter and no alpha conversion.
        Parameters:
        device - The device the filter will run on
        srcAlpha - The alpha encoding for the source texture
        destAlpha - The alpha encoding for the destination texture
        backgroundColor - An array of CGFloats giving the background color to use when flattening an image. The color is in the source colorspace. The length of the array is the number of color channels in the src colorspace. If NULL, use {0}.
        conversionInfo - The colorspace conversion to use. May be NULL, indicating no color space conversions need to be done.
        Returns:
        An initialized MPSImageConversion object.

      • sourceAlpha

        public long sourceAlpha()
        [@property] sourceAlpha Premultiplication description for the source texture Most colorspace conversion operations can not work directly on premultiplied data. Use this property to tag premultiplied data so that the source texture can be unpremultiplied prior to application of these transforms. Default: MPSPixelAlpha_AlphaIsOne

      • initWithCoderDevice

        public MPSImageConversion initWithCoderDevice​(NSCoder aDecoder,
                                              java.lang.Object device)
        Description copied from class: MPSUnaryImageKernel
        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
