# kVTDecompressionPropertyKey_SupportedPixelFormatsOrderedByQuality

An array indicating quality levels among pixel formats.

## Declaration

```swift
let kVTDecompressionPropertyKey_SupportedPixelFormatsOrderedByQuality: CFString
```

## Discussion

Discussion This is an optional property for video decoders to implement. This property value is an array containing CFNumber objects holding CMPixelFormatType values, ordered by quality from best to worse.
