Class CIRenderDestination

  • All Implemented Interfaces:
    NSObject
    public class CIRenderDestination
extends NSObject
    This is a lightweight API to allow clients to specify all the attributes of a render that pertain to the render's destination. It is intended to be used for issuing renders that return to the caller as soon as all the work has been issued but before it completes/

        Create a CIRenderDestination based on client-managed buffer. The 'data' parameter must point to a buffer that is at least bytesPerRow * height bytes in size. The destination's 'colorspace' property will default a CGColorSpace created with kCGColorSpaceSRGB, kCGColorSpaceExtendedSRGB, or kCGColorSpaceGenericGrayGamma2_2.

      • initWithGLTextureTargetWidthHeight

        public CIRenderDestination initWithGLTextureTargetWidthHeight​(int texture,
                                                              int target,

        Create a CIRenderDestination based on an OpenGL texture. Rendering to a GLTexture-backed CIRenderDestination is only supported by GLContext-backed CIContexts. The texture id must be bound to a GLContext that is shared with that of the GLContext-backed CIContext. The destination's 'colorspace' property will default a CGColorSpace created with kCGColorSpaceSRGB, kCGColorSpaceExtendedSRGB, or kCGColorSpaceGenericGrayGamma2_2.

      • initWithIOSurface

        public CIRenderDestination initWithIOSurface​(IOSurface surface)
        Create a CIRenderDestination based on an IOSurface object. The destination's 'colorspace' property will default a CGColorSpace created by, querying the IOSurface attributes.

      • initWithMTLTextureCommandBuffer

        public CIRenderDestination initWithMTLTextureCommandBuffer​(MTLTexture texture,
                                                           MTLCommandBuffer commandBuffer)
        A render to a MTLTexture-backed CIRenderDestination is only supported by MTLTexture-backed CIContexts. The texture must have a MTLTextureType of MTLTextureType2D An optional MTLCommandBuffer can be specified, with which to use for rendering to the MTLTexture. NOTE: Rendering to a texture initialized with a commandBuffer requires encoding all the commands to render an image into the specified buffer. This may impact system responsiveness and may result in higher memory usage if the image requires many passes to render. To avoid this impact, it is recommended to create a context using [CIContext contextWithMTLCommandQueue:] and create the CIRenderDestination without specifying a buffer. The destination's 'colorspace' property will default a CGColorSpace created with kCGColorSpaceSRGB, kCGColorSpaceExtendedSRGB, or kCGColorSpaceGenericGrayGamma2_2.

      • initWithPixelBuffer

        public CIRenderDestination initWithPixelBuffer​(CVBufferRef pixelBuffer)
        Create a CIRenderDestination based on a CVPixelBufferRef object. The destination's 'colorspace' property will default a CGColorSpace created by, querying the CVPixelBufferRef attributes.

      • initWithWidthHeightPixelFormatCommandBufferMtlTextureProvider

        public CIRenderDestination initWithWidthHeightPixelFormatCommandBufferMtlTextureProvider​(long width,
                                                                                         long height,

                                                                                         CIRenderDestination.Block_initWithWidthHeightPixelFormatCommandBufferMtlTextureProvider block)
        Create a CIRenderDestination based on a Metal texture. Rendering to a MTLTexture-backed CIRenderDestination is only supported by MTLTexture-backed CIContexts. The provider 'block' will be called lazily when the destination is rendered to. The block must return a texture with a MTLTextureType of MTLTextureType2D. The 'width', 'height' and 'pixelFormat' argument values should be the same as the width, height and pixelFormat of the MTLTexture that will be returned by 'block' An optional MTLCommandBuffer can be specified, with which to use for rendering to the MTLTexture. NOTE: Rendering to a texture initialized with a commandBuffer requires encoding all the commands to render an image into the specified buffer. This may impact system responsiveness and may result in higher memory usage if the image requires many passes to render. To avoid this impact, it is recommended to create a context using [CIContext contextWithMTLCommandQueue:] and create the CIRenderDestination without specifying a buffer. The destination's 'colorspace' property will default a CGColorSpace created with kCGColorSpaceSRGB, kCGColorSpaceExtendedSRGB, or kCGColorSpaceGenericGrayGamma2_2.

      • isClamped

        public boolean isClamped()
        If true, the render will clamp color channels to 0..alpha if 'alphaMode' is premultiplied otherwise 0..1 This property is initialized to false if the destination's format supports extended range

      • isDithered

        public boolean isDithered()
        Instructs the render to add pseudo-random luma noise given the depth of the destination. The magnitude of the noise is approximatly ±pow(2,-(bitPerComponent+1))

      • isFlipped

        public boolean isFlipped()
        The logical coordinate system of a CIRenderDestination is always cartesian: (0,0) represents the lower-left corner (0.5,0.5) represents the lower-left pixel center (pixelsWide-0.5,pixelsHigh-0.5) represents the upper-right pixel center (pixelsWide,pixelsHigh) represents the upper-right corner. The 'flipped' property controls how pixels this logical coordinate system are stored into the memory of the object backing the destination. If 'flipped' is false, then the base address of the backing stores the pixel centered on the logical coordinate (0.5,0.5) If 'flipped' is true, then the base address of the backing stores the pixel centered on the logical coordinate (0.5,height-0.5)
