# vImageConverter

A description of a conversion from one image format to another.

## Declaration

```swift
class vImageConverter
```

## Mentioned in

Applying color transforms to images with a multidimensional lookup table Building a basic image conversion workflow Converting chroma-subsampled images

## Overview

Overview The vImageConverter class is an opaque type that contains information needed to do a rapid conversion from one image type to another. You use the converter creation functions, for example, vImageConverter_CreateWithCGImageFormat(_:_:_:_:_:), to create instances of converters. Sometimes, there can be an overhead when creating a converter, so create them in advance and reuse them. Converters are thread safe; that is, you can use the same object concurrently in multiple threads.
