# Dithering Methods

Specify the dithering method some vImage conversion functions use.

## Topics

### Constants

[`kvImageConvert_DitherNone`](/documentation/Accelerate/kvImageConvert_DitherNone)

A constant that indicates the conversion will not apply dithering.

[`kvImageConvert_DitherOrdered`](/documentation/Accelerate/kvImageConvert_DitherOrdered)

A constant that indicates the conversion will add randomized, pre-computed blue noise to the image.

[`kvImageConvert_DitherOrderedReproducible`](/documentation/Accelerate/kvImageConvert_DitherOrderedReproducible)

A constant that indicates the conversion will add reproducible, pre-computed blue noise to the image.

[`kvImageConvert_DitherFloydSteinberg`](/documentation/Accelerate/kvImageConvert_DitherFloydSteinberg)

A constant that indicates the conversion will add Floyd-Steinberg dithering to the image.

[`kvImageConvert_DitherAtkinson`](/documentation/Accelerate/kvImageConvert_DitherAtkinson)

A constant that indicates the conversion will add Atkinson dithering to the image.

[`kvImageConvert_OrderedGaussianBlue`](/documentation/Accelerate/kvImageConvert_OrderedGaussianBlue)

A constant that indicates the conversion will distribute the noise according to a Gaussian distribution.

[`kvImageConvert_OrderedUniformBlue`](/documentation/Accelerate/kvImageConvert_OrderedUniformBlue)

A constant that indicates the conversion will distribute the noise uniformly.

[`kvImageConvert_OrderedNoiseShapeMask`](/documentation/Accelerate/kvImageConvert_OrderedNoiseShapeMask)
