Class MPSImageSobel

  • All Implemented Interfaces:
    NSCoding, NSCopying, NSSecureCoding, NSObject
    public class MPSImageSobel
extends MPSUnaryImageKernel
    MPSImageSobel The MPSImageSobel implements the Sobel filter. When the color model (e.g. RGB, two-channel, grayscale, etc.) of source and destination textures match, the filter is applied to each channel separately. If the destination is monochrome (single channel) but source multichannel, the pixel values are converted to grayscale before applying Sobel operator using the linear gray color transform vector (v). Luminance = v[0] * pixel.x + v[1] * pixel.y + v[2] * pixel.z;

      • initWithDevice

        public MPSImageSobel initWithDevice​(java.lang.Object device)
        Initialize a Sobel filter on a given device using the default color transform. Default: BT.601/JPEG {0.299f, 0.587f, 0.114f} For non-default conversion matrices, use -initWithDevice:linearGrayColorTransform:
        Overrides:
        initWithDevice in class MPSUnaryImageKernel
        Parameters:
        device - The device the filter will run on
        Returns:
        A valid object or nil, if failure.

      • initWithDeviceLinearGrayColorTransform

        public MPSImageSobel initWithDeviceLinearGrayColorTransform​(MTLDevice device,
                                                            org.moe.natj.general.ptr.ConstFloatPtr transform)
        Initialize a Sobel filter on a given device with a non-default color transform [@code] Luminance = transform[0] * pixel.x + transform[1] * pixel.y + transform[2] * pixel.z; [@endcode]
        Parameters:
        device - The device the filter will run on
        transform - Array of three floats describing the rgb to gray scale color transform.
        Returns:
        A valid object or nil, if failure.

      • initWithCoderDevice

        public MPSImageSobel 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.

        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.
