Functions

func CIContextOfflineGPUCount 

func CIContextOfflineGPUCount() uint

Returns the number of GPUs not currently driving a display.

func CIDetectorAccuracy 

func CIDetectorAccuracy() uintptr

func CIDetectorAccuracyHigh 

func CIDetectorAccuracyHigh() uintptr

func CIDetectorAccuracyLow 

func CIDetectorAccuracyLow() uintptr

func CIDetectorAspectRatio 

func CIDetectorAspectRatio() uintptr

A dictionary key that configures a Core Image rectangle feature detection operation to search for a rectangle of a desired aspect ratio (width divided by height). This option is used with “/CIDetector/featuresInImage:options:“ The value for this key needs to be is a positive float number. Use this option with a “CIDetectorTypeRectangle“ detector to fine-tune the accuracy of the detector. For example, to more accurately find a business card (3.5 x 2 inches) in an image, specify an aspect ratio of 1.75. If this key is not specified, the a default value of 1.6 is used. 

func CIDetectorEyeBlink() uintptr

A dictionary key that configures a Core Image face feature detection operation to perform additional processing to recognize closed eyes in detected faces. This option is used with “/CIDetector/featuresInImage:options:“ If the value of the key is true, then facial expressions such as blinking and smiles are extracted. This is needed for the “/CIFaceFeature/leftEyeClosed-property“ and “/CIFaceFeature/rightEyeClosed-property“ to function.

func CIDetectorFocalLength 

func CIDetectorFocalLength() uintptr

A dictionary key that configures a Core Image rectangle feature detection operation to account for the focal length of the camera used for the image. This option is used with “/CIDetector/featuresInImage:options:“ The value of this key is an NSNumber object whose value is a floating-point number. Use this option with the CIDetectorTypeRectangle detector type to control the effect of the CIDetectorAspectRatio option on feature detection. This option’s value can be 0.0, -1.0, or any positive value: * The special value of -1.0 (the default) disables the aspect ratio test for the returned rectangle. * The special value of 0.0 enables a less precise test of aspect ratio that approximates an orthographic (non-perspective) projection. Use this value if you want to specify the aspect ratio of the rectangle via the CIDetectorAspectRatio option, but have no means of determining the value for the focal length in pixels. See below for a method to compute an approximate value for the focal length in pixels. * Any other value specifies the camera focal length, in pixels, allowing the aspect ratio specification to account for perspective distortion of rectangles in the input image. If you know the diagonal field of view of the camera (the scene angle subtended by the diagonal corners of an image), you can use the following formula to compute an approximate focal length in pixels: `focal_length_pixels = (image_diagonal_pixels/2)/tan(FOV/2)` In this formula, `image_diagonal_pixels` is the length (in pixels) of the image diagonal of the maximum resolution of the camera sensor. For example, this value is: * `4080` pixels for a `3264 x 2448` (8 megapixel) sensor * `5000` pixels for a `4096 x 3024` (12 megapixel) sensor. To measure diagonal field of view, put the camera on a tripod so that it is perpendicular to a surface and the center of the image is oriented on a mark on the surface. Measure the distance from the mark to one of the corner points of the image (Y). Measure the distance from the camera to the surface (Z). The field of view is then `2*arctan(Y/Z)`. You must specify this value in terms of the maximum sensor resolution. If the supplied CIImage has been scaled relative relative to the maximum sensor resolution, the supplied focal length must also be similarly scaled.

func CIDetectorImageOrientation 

func CIDetectorImageOrientation() uintptr

A dictionary key that configures a Core Image feature detection operation to account for the orientation the image. This option is used with “/CIDetector/featuresInImage:options:“ The value of this key is an number object whose value is an integer between 1 and 8. The TIFF and EXIF specifications define the orientation values that describe how the image should be displayed. The default value is 1. For further details, see `CGImagePropertyOrientation`. The “CIDetectorTypeFace“ and “CIDetectorTypeText“ can use this option to correctly find faces or text. Regardless of the orientation values the “/CIFeature/bounds-property“ which is always measured in the cartesean coordinates system of the image that you pass to the detector.

This option is used with “/CIDetector/featuresInImage:options:“ If the value for this option configures the “CIDetectorTypeText“ detector as follows: * False: detect only in regions likely to contain text. * True: detect in regions likely to contain individual characters. If this key is not specified, the a default is False.

func CIDetectorSmile 

func CIDetectorSmile() uintptr

A dictionary key that configures a Core Image face feature detection operation to perform additional processing to recognize smiles in detected faces. This option is used with “/CIDetector/featuresInImage:options:“ If the value of the key is true, then facial expressions such as blinking and smiles eyes are extracted. This is needed for the “/CIFaceFeature/hasSmile-property“ to function.

If a context caches intermediate buffers, then subsequent renders of a similar image using the same context may be able to render faster. If a context does not cache intermediate buffers, then it may use less memory. If the value for this option is: * True: The context will cache intermediate results for future renders using the same context. * False: The context will not cache intermediate results. * Not specified: the default behavior True. > Note: > * This option does affect how “/CIImage/imageByInsertingIntermediate“ behaves. > * This option does not affect how “/CIImage/imageByInsertingIntermediate:“ behaves.

The higher quality behavior performs downsampling operations in multiple passes in order to reduce aliasing artifacts. The lower quality behavior performs downsampling operations a single pass in order to improve performance. If the value for this option is: * True: The higher quality behavior will be used. * False: The lower quality behavior will be used. * Not specified: the default behavior is True on macOS and False on other platforms. > Note: > * This option does affect how “/CIImage/imageByApplyingTransform:“ operations are performed by the context. > * This option does not affect how “/CIImage/imageByApplyingTransform:highQualityDownsample:“ behaves.

func KCIContextMemoryLimit 

func KCIContextMemoryLimit() uintptr

A number value to control the maximum memory in megabytes that the context allocates for render tasks. Larger values could increase memory footprint while smaller values could reduce performance.

A Boolean value to specify a client-provided name for a context. This name will be used in QuickLook graphs and the output of CI_PRINT_TREE.

func KCIContextOutputColorSpace 

func KCIContextOutputColorSpace() *foundation.NSString

A Core Image context option key to specify the default destination color space for rendering. This option only affects how Core Image renders using the following methods: * “/CIContext/createCGImage:fromRect:“ * “/CIContext/drawImage:atPoint:fromRect:“ * “/CIContext/drawImage:inRect:fromRect:“ With all other render methods, the destination color space is either specified as a parameter or can be determined from the object being rendered to. The value of this option can be either: * A `CGColorSpace` instance with an RGB or monochrome color model that supports output. * An `NSNull` instance to indicate that the context should not match from the working space to the destination. If this option is not specified, then the default output space is sRGB.

func KCIContextOutputPremultiplied 

func KCIContextOutputPremultiplied() uintptr

A Boolean value to control how a Core Image context render produces alpha-premultiplied pixels. This option only affects how a context is rendered when using methods where the destination's alpha mode cannot be determined such as: * “/CIContext/render:toBitmap:rowBytes:bounds:format:colorSpace:“ * “/CIContext/render:toCVPixelBuffer:“ * “/CIContext/render:toIOSurface:bounds:colorSpace:“ * “/CIContext/render:toMTLTexture:commandBuffer:bounds:colorSpace:“ * “/CIContext/createCGImage:fromRect:“ If the value for this option is: * True: The output will produce alpha-premultiplied pixels. * False: The output will produce un-premultiplied pixels. * Not specified: the default behavior True. This option does not affect how a context is rendered to a “CIRenderDestination“ because that API allows you to set or override the alpha behavior using “/CIRenderDestination/alphaMode“.

func KCIContextPriorityRequestLow 

func KCIContextPriorityRequestLow() uintptr

A Boolean value to control the priority Core Image context renders. If this value is True, then rendering with the context from a background thread takes lower priority than other GPU usage from the main thread. This allows your app to perform Core Image rendering without disturbing the frame rate of UI animations.

func KCIContextUseSoftwareRenderer 

func KCIContextUseSoftwareRenderer() *foundation.NSString

A Boolean value to control if a Core Image context will use a software renderer. > Note: This option has no effect if the platform does not support OpenCL.

func KCIContextWorkingColorSpace 

func KCIContextWorkingColorSpace() *foundation.NSString

A Core Image context option key to specify the working color space for rendering. Contexts support automatic color management by performing all processing operations in a working color space. This means that unless told otherwise: * All input images are color matched from the input's color space to the working space. * All renders are color matched from the working space to the destination's color space. The default working space is the extended sRGB color space with linear gamma. On macOS before 10.10, the default is extended Generic RGB with linear gamma. The value of this option can be either: * A `CGColorSpace` instance with an RGB color model that supports output. * An `NSNull` instance to request that Core Image perform no color management. If this option is not specified, then the default working space is used.

func KCIContextWorkingFormat 

func KCIContextWorkingFormat() uintptr

A Core Image context option key to specify the pixel format to for intermediate results when rendering. The value for this key is an `NSNumber` instance containing a “CIFormat“ value. The supported values for the working pixel format are: “CIFormat“ | Notes ------------------- | -------------- “kCIFormatRGBA8“ | Uses less memory but has less precision an range “kCIFormatRGBAh“ | Uses 8 bytes per pixel, supports HDR “kCIFormatRGBAf“ | Only on macOS If this option is not specified, then the default is “kCIFormatRGBAh“. (The default is “kCIFormatRGBA8“ if your if app is linked against iOS 12 SDK or earlier.)

These codewords have dummy bits inserted to ensure that an entire codeword isn't all 0's or all 1's. Clients will need to remove these extra bits as part of interpreting the payload.

func (*CIAztecCodeDescriptor) InitWithPayloadIsCompactLayerCountDataCodewordCount 

func (o *CIAztecCodeDescriptor) InitWithPayloadIsCompactLayerCountDataCodewordCount(errorCorrectedPayload *foundation.NSData, isCompact bool, layerCount int, dataCodewordCount int) *CIAztecCodeDescriptor

func (*CIAztecCodeDescriptor) LayerCount 

func (o *CIAztecCodeDescriptor) LayerCount() int

The number of data layers in the Aztec code symbol. Combined with “isCompact-property“, the number of data layers determines the number of modules in the Aztec Code symbol. Valid values range from 1 to 32. Compact symbols can have up to 4 data layers. The number of data layers also determines the number of bits in each data codeword of the message carried by the Aztec Code symbol.

If the a CIImage is initialized using: * `NSURL` or `NSData` : the headroom may be determined by associated metadata or deduced from pixel format or colorSpace information. * `CGImage` : headroom may be determined by `CGImageGetHeadroomInfo()` or deduced from pixel format or colorSpace information. * `IOSurface` : then the headroom will be determined by `kIOSurfaceContentHeadroom`. or deduced from pixel format or colorSpace information. * `CVPixelBuffer` : then the headroom will be determined by `kCVImageBufferContentLightLevelInfoKey`. or deduced from pixel format or colorSpace information. * `BitmapData` : headroom may be deduced from pixel format or colorSpace information. If the image is the result of applying a “CIFilter-class“ or “CIKernel“, this method will return `0.0`. There are exceptions to this. Applying a `CIWarpKernel“ or certain “CIFilter-class“ (e.g. `CIGaussianBlur`, `CILanczosScaleTransform`, `CIAreaAverage` and some others) to an image will result in a “CIImage“ instance with the same `contentHeadroom` property value.
