clearCaches

public void clearCaches()

Frees any cached data (such as temporary images) associated with the context. This also runs the garbage collector.

createCGImageFromRect

public CGImageRef createCGImageFromRect(CIImage image,
                                        CGRect fromRect)

Render the region 'fromRect' of image 'image' into a temporary buffer using the context, then create and return a new CoreGraphics image with the results. The caller is responsible for releasing the returned image. The return value will be null if size is empty or too big.

createCGImageFromRectFormatColorSpace

public CGImageRef createCGImageFromRectFormatColorSpace(CIImage image,
                                                        CGRect fromRect,

This will return null if fromRect is empty or infinite or the format isn't supported.

createCGImageFromRectFormatColorSpaceDeferred

public CGImageRef createCGImageFromRectFormatColorSpaceDeferred(CIImage image,
                                                                CGRect fromRect,

                                                                CGColorSpaceRef colorSpace,
                                                                boolean deferred)

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.

drawImageAtPointFromRect

@Deprecated
public void drawImageAtPointFromRect(CIImage image,
                                                 CGPoint atPoint,

drawImageInRectFromRect

public void drawImageInRectFromRect(CIImage image,
                                    CGRect inRect,
                                    CGRect fromRect)

renderToBitmapRowBytesBoundsFormatColorSpace

public void renderToBitmapRowBytesBoundsFormatColorSpace(CIImage image,
                                                         org.moe.natj.general.ptr.VoidPtr data,
                                                         long rowBytes,

                                                         CGColorSpaceRef colorSpace)

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

public void renderToCVPixelBuffer(CIImage image,
                                  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.

renderToCVPixelBufferBoundsColorSpace

public void renderToCVPixelBufferBoundsColorSpace(CIImage image,
                                                  CVBufferRef buffer,
                                                  CGRect bounds,
                                                  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.

renderToMTLTextureCommandBufferBoundsColorSpace

public void renderToMTLTextureCommandBufferBoundsColorSpace(CIImage image,
                                                            MTLTexture texture,

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:].

workingColorSpace

public CGColorSpaceRef workingColorSpace()

The working color space of the CIContext The property will be null if the context was created with color management disabled.

workingFormat

public int workingFormat()

This is an optional call which can be used to "warm up" a CIContext so that a subsequent call to render with the same arguments can be more efficient. By making this call, Core Image will ensure that - any needed kernels will be compiled - any intermedate buffers are allocated and marked volatile

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];
