# Functions that convert between noninteger planar buffers

Convert the bit depths and formats of planar fixed- and floating-point image data.

## Topics

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

[`func vImageConvert_16Fto16Q12(UnsafePointer<vImage_Buffer>, UnsafePointer<vImage_Buffer>, vImage_Flags) -> vImage_Error`](/documentation/Accelerate/vImageConvert_16Fto16Q12(_:_:_:))

Converts a floating-point 16-bit planar buffer to a fixed-point 16-bit planar buffer.

[`func vImageConvert_Planar16FtoPlanarF(UnsafePointer<vImage_Buffer>, UnsafePointer<vImage_Buffer>, vImage_Flags) -> vImage_Error`](/documentation/Accelerate/vImageConvert_Planar16FtoPlanarF(_:_:_:))
