vImage.PixelBuffer
struct · iOS 16.0+ · SDK 27.1
struct PixelBuffer<Format> where Format : PixelFormatA structure that stores an image's data, dimensions, bit depth, and number of channels. Use a `vImage.PixelBuffer` to represent an image from a `CGImage`, `CVPixelBuffer`, or collection of raw pixel values. Pixel buffers are typed by their bits per channel and number of channels. For example, `vImage.PixelBuffer<vImage.Interleaved8x4>` indicates a 4-channel, 8-bit per channel image, such as RGBA, ARGB, or CMYK. Pixel buffers expose methods that are available for the buffer's bit depth. For example, the fast box convolution functions are only available for one- and four-channel 8-bit per channel buffers: let src = vImage.PixelBuffer<vImage.Interleaved8x4>(cgImage: cgImage, cgImageFormat: &cgImageFormat) let dest = vImage.PixelBuffer<vImage.Interleaved8x4>(src.size) src.boxConvolve(kernelSize: vImage.Size(width: 64, height: 64), edgeMode: .truncateKernel, destination: dest) Typed pixel buffers provide a simple API to convert between pixel formats. For example, the following code converts 8-bit unsigned integer pixels to 32-bit floating point pixels: let src = vImage.PixelBuffer<vImage.Interleaved8x4>(cgImage: cgImage, cgImageFormat: &cgImageFormat) let dest = vImage.PixelBuffer<vImage.InterleavedFx4>(size: src.size) src.convert(to: dest)
