formatCode
The four-character code that encodes the pixel format of the Core Video image format.
Declaration
var formatCode: UInt32 { get }Discussion
For example, the following code prints the format code of a kCVPixelFormatType_420YpCbCr8Planar Core Video image format that equals the expected type:
let cvImageFormat = vImageCVImageFormat.make(
format: .format420YpCbCr8Planar,
matrix: kvImage_ARGBToYpCbCrMatrix_ITU_R_709_2.pointee,
chromaSiting: .center,
colorSpace: CGColorSpace(name: CGColorSpace.sRGB)!,
alphaIsOpaqueHint: true)!
// Prints "true".
print(cvImageFormat.formatCode == kCVPixelFormatType_420YpCbCr8Planar)
