# Functions that convert from noninteger planar buffers to integer planar buffers

Convert planar fixed- and floating-point image data to integer format.

## Topics

### Converting from fixed-point 16-bit-per-channel buffers

[`func vImageConvert_16Q12to8(UnsafePointer<vImage_Buffer>, UnsafePointer<vImage_Buffer>, vImage_Flags) -> vImage_Error`](/documentation/Accelerate/vImageConvert_16Q12to8(_:_:_:))

Converts a fixed-point 16-bit planar buffer to an 8-bit planar buffer.

[`func vImageConvert_16Q12to16U(UnsafePointer<vImage_Buffer>, UnsafePointer<vImage_Buffer>, vImage_Flags) -> vImage_Error`](/documentation/Accelerate/vImageConvert_16Q12to16U(_:_:_:))

Converts a fixed-point 16-bit planar buffer to an unsigned 16-bit planar buffer.

### Converting from floating-point 16-bit-per-channel buffers

[`func vImageConvert_Planar16FtoPlanar8(UnsafePointer<vImage_Buffer>, UnsafePointer<vImage_Buffer>, vImage_Flags) -> vImage_Error`](/documentation/Accelerate/vImageConvert_Planar16FtoPlanar8(_:_:_:))
