        Create a new CGImage from the specified subrect of the image. The new CGImageRef will be created in the specified format and colorspace. The return value will be null if fromRect is empty or infinite. The CGColorSpace must be kCGColorSpaceModelRGB or kCGColorSpaceModelMonochrome and must match the specified CIFormat. This will return null if fromRect is empty or infinite or the format isn't supported. If deferred is NO, then the CIImage will be rendered once when this method is called. If deferred is YES, then the CIImage will be rendered whenever the CGImage is rendered.

        Render 'image' to the given bitmap. The 'data' parameter must point to at least rowBytes*floor(bounds.size.height) bytes. The 'bounds' parameter has the following behavior: The 'bounds' parameter acts to specify the region of 'image' to render. This region (regardless of its origin) is rendered at upper-left corner of 'data'. Passing a 'colorSpace' value of null means: Disable output color management if app is linked against iOS SDK Disable output color management if app is linked against OSX 10.11 SDK or later Match to context's output color space if app is linked against OSX 10.10 SDK or earlier

      • renderToCVPixelBuffer

                                  CVBufferRef buffer)
        Render 'image' into the given CVPixelBuffer. In OS X 10.11.3 and iOS 9.3 and later CI will color match to the colorspace of the buffer. otherwise CI will color match to the context's output colorspace.

                                                  CGColorSpaceRef colorSpace)
        Render 'image' to the given CVPixelBufferRef. The 'bounds' parameter has the following behavior: In OS X and iOS 9 and later: The 'image' is rendered into 'buffer' so that point (0,0) of 'image' aligns to the lower left corner of 'buffer'. The 'bounds' acts like a clip rect to limit what region of 'buffer' is modified. In iOS 8 and earlier: The 'bounds' parameter acts to specify the region of 'image' to render. This region (regardless of its origin) is rendered at upper-left corner of 'buffer'. If 'colorSpace' is nil, CI will not color match to the destination.

        Render 'bounds' of 'image' to a Metal texture, optionally specifying what command buffer to use. Texture type must be MTLTexture2D. 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:].

        Renders a portion of image to a point of destination It renders as if 'image' is cropped to 'fromRect' and the origin of the result is placed at 'atPoint' If image.extent and fromRect are infinite, then it renders so that point (0,0) of image is placed at 'atPoint' MTLTexture-backed CIRenderDestinations are only supported by MTLTexture-backed CIContexts. GLTexture-backed CIRenderDestinations are only supported by GLContext-backed CIContexts. For contexts that are initialized with a command queue, this call will return as soon as all the work for the render is enqueued on the context's device. Otherwise, it will return as soon as all the work is scheduled. In many situations, after issuing a render, the client can use the destination or its backing object without waiting for the enqueued work to complete. For example, after rendering a surface CIRenderDestination, the surface can be passed on for further processing by the GPU. In other situations, the client may need to wait for the render to be complete. For example, after rendering a surface CIRenderDestination, the surface can be accessed by CPU code by calling IOSurfaceGetBytePointer only after the render is completed. In this case the client can use the returned CIRenderTask like this: CIRenderTask* task = [context render:...]; [task waitUntilCompletedAndReturnError:&error];
