# highQualityDownsample

A Boolean value to control the quality of image downsampling operations performed by the Core Image context.

## Declaration

```swift
static let highQualityDownsample: CIContextOption
```

## Discussion

Discussion The higher quality behavior performs downsampling operations in multiple passes in order to reduce aliasing artifacts. The lower quality behavior performs downsampling operations a single pass in order to improve performance. If the value for this option is: True: The higher quality behavior will be used. False: The lower quality behavior will be used. Not specified: the default behavior is True on macOS and False on other platforms. note: This option does affect how /CIImage/imageByApplyingTransform: operations are performed by the context. This option does not affect how /CIImage/imageByApplyingTransform:highQualityDownsample: behaves.
