init

static initCgImageFlags(cgImage: _CoreGraphics_CGImage, options?: vImage_Options): vImage_Buffer

init(cgImage: CGImage, flags options: vImage.Options = .noFlags) throws

Initialize a vImage buffer with the contents of a Core Graphics image. - Parameter cgImage: A `CGImage` instance to be used as the source. - Parameter options: The options to use when performing this operation. - Returns: An initialized vImage buffer. This function will instantiate and initialize a vImage buffer from a `CGImage` using a `CGImageFormat` based on the provided image's properties.

static initCgImageFormatFlags(cgImage: _CoreGraphics_CGImage, format: vImage_CGImageFormat, options?: vImage_Options): vImage_Buffer

init(cgImage: CGImage, format: vImage_CGImageFormat, flags options: vImage.Options = .noFlags) throws

Initialize a vImage buffer with the contents of a Core Graphics image, using a supplied format. - Parameter cgImage: A `CGImage` instance to be used as the source. - Parameter format: A `vImage_CGImageFormat` that describes the source image/ - Parameter options: The options to use when performing this operation. - Returns: An initialized vImage buffer. This function will instantiate and initialize a vImage buffer from a `CGImage` using a provided `CGImageFormat`.

createCGImage

createCGImage(format: vImage_CGImageFormat, options?: vImage_Options): _CoreGraphics_CGImage

func createCGImage(format: vImage_CGImageFormat, flags options: vImage.Options = .noFlags) throws -> CGImage

Creates a `CGImage` instance from a vImage buffer - Parameter format: The image format of this vImage buffer. - Parameter options: The options to use when performing this operation. - Returns: A Core Graphics image containing a representation of the vImage buffer.

preferredAlignmentAndRowBytes

static preferredAlignmentAndRowBytes(width: number, height: number, bitsPerPixel: number): { "alignment": number; "rowBytes": number }

static func preferredAlignmentAndRowBytes(width: Int, height: Int, bitsPerPixel: UInt32) throws -> (alignment: Int, rowBytes: Int)

Returns the preferred alignment and row bytes for a specified buffer size and bits-per-pixel. - Parameter width: The width of the buffer. - Parameter height: The height of the buffer. - Parameter bitsPerPixel: The number of bits in a pixel of image data. - Returns: The preferred alignment and row bytes.

copy

copy(destinationBuffer: vImage_Buffer, pixelSize: number, options?: vImage_Options): { $ret: null; $out: { "destinationBuffer": vImage_Buffer } }

func copy(destinationBuffer: inout vImage_Buffer, pixelSize: Int, flags options: vImage.Options = .noFlags) throws

Copies this buffer to `destinationBuffer`. - Parameter destinationBuffer: The destination vImage buffer. - Parameter pixelSize: The number of bytes for one pixel. - Parameter options: The options to use when performing this operation.

Omit the output parameters from the call. The result contains $ret and $out, with destinationBuffer inside $out.

init

static initSizeBitsPerPixel(size: { width: number; height: number }, bitsPerPixel: number): vImage_Buffer

init(size: CGSize, bitsPerPixel: UInt32) throws

Initializes a vImage buffer of a specified size. - Parameter size: The size of the buffer. - Parameter bitsPerPixel: The number of bits in a pixel of image data. - Returns: An initialized vImage buffer.

size

get size(): { width: number; height: number }

var size: CGSize { get }

The size of the vImage buffer. The `CGSize` is rounded down to the nearest representable `CGFloat` that is less than or equal to the actual size of the image. In practice the conversion will always be exact, except for really big images. In that case, some part of the bottom or right edge might be truncated.

init

static initWidthHeightBitsPerPixel(width: number, height: number, bitsPerPixel: number): vImage_Buffer

init(width: Int, height: Int, bitsPerPixel: UInt32) throws

Initializes a vImage buffer of a specified size. - Parameter width: The width of the buffer. - Parameter height: The height of the buffer. - Parameter bitsPerPixel: The number of bits in a pixel of image data. - Returns: An initialized vImage buffer.
