# formatCode

The four-character code that encodes the pixel format of the Core Video image format.

## Declaration

```swift
var formatCode: UInt32 { get }
```

## Discussion

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)
