vImageConverter

Declaration

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

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.
