# vImage Operations

Apply image manipulation operations to vImage buffers.

## Overview

Overview A vImage function name includes the data type of the buffer it operates on. For example, vImageConvolve_Planar8(_:_:_:_:_:_:_:_:_:_:_:) works with 8-bit planar buffers, and vImageConvolve_ARGBFFFF(_:_:_:_:_:_:_:_:_:_:) works with 32-bits-per-channel, four-channel interleaved buffers.
