# vImage Operations

Apply image manipulation operations to vImage buffers.

## Discussion

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