# Functions that convert from noninteger interleaved buffers to integer interleaved buffers Convert interleaved fixed- and floating-point image data to integer format. ## Topics ### Converting from floating-point 32-bit-per-channel buffers [`func vImageConvert_RGBFFFtoRGB888_dithered(UnsafePointer, UnsafePointer, UnsafePointer, UnsafePointer, Int32, vImage_Flags) -> vImage_Error`](/documentation/Accelerate/vImageConvert_RGBFFFtoRGB888_dithered(_:_:_:_:_:_:)) Converts a floating-point 32-bit-per-channel, 3-channel buffer to an 8-bit-per-channel, 3-channel buffer using the specified dithering algorithm. [`func vImageConvert_ARGBFFFFtoARGB8888_dithered(UnsafePointer, UnsafePointer, UnsafePointer, UnsafePointer, Int32, UnsafePointer!, vImage_Flags) -> vImage_Error`](/documentation/Accelerate/vImageConvert_ARGBFFFFtoARGB8888_dithered(_:_:_:_:_:_:_:)) Converts a floating-point 32-bit-per-channel, 4-channel buffer to an 8-bit-per-channel, 4-channel buffer using the specified dithering algorithm. ### Converting from XRGB2101010 32-bit buffers [`func vImageConvert_ARGB2101010ToARGB8888(UnsafePointer, UnsafePointer, Int32, Int32, UnsafePointer!, vImage_Flags) -> vImage_Error`](/documentation/Accelerate/vImageConvert_ARGB2101010ToARGB8888(_:_:_:_:_:_:)) Converts an ARGB2101010 32-bit, 4-channel interleaved buffer to an 8-bit-per-channel, 4-channel interleaved buffer with permutation. [`func vImageConvert_XRGB2101010ToARGB8888(UnsafePointer, Pixel_8, UnsafePointer, Int32, Int32, UnsafePointer!, vImage_Flags) -> vImage_Error`](/documentation/Accelerate/vImageConvert_XRGB2101010ToARGB8888(_:_:_:_:_:_:_:)) Converts an XRGB2101010 32-bit, 4-channel interleaved buffer to an 8-bit-per-channel, 4-channel interleaved buffer with permutation. [`func vImageConvert_ARGB2101010ToARGB16U(UnsafePointer, UnsafePointer, Int32, Int32, UnsafePointer!, vImage_Flags) -> vImage_Error`](/documentation/Accelerate/vImageConvert_ARGB2101010ToARGB16U(_:_:_:_:_:_:)) Converts an ARGB2101010 32-bit, 4-channel interleaved buffer to an unsigned 16-bit-per-channel, 4-channel interleaved buffer with permutation. [`func vImageConvert_XRGB2101010ToARGB16U(UnsafePointer, UInt16, UnsafePointer, Int32, Int32, UnsafePointer!, vImage_Flags) -> vImage_Error`](/documentation/Accelerate/vImageConvert_XRGB2101010ToARGB16U(_:_:_:_:_:_:_:)) Converts an XRGB2101010 32-bit, 4-channel interleaved buffer to an unsigned 16-bit-per-channel, 4-channel interleaved buffer with permutation. ### Converting from RGBX1010102 32-bit buffers [`func vImageConvert_RGBA1010102ToARGB8888(UnsafePointer, UnsafePointer, Int32, Int32, UnsafePointer!, vImage_Flags) -> vImage_Error`](/documentation/Accelerate/vImageConvert_RGBA1010102ToARGB8888(_:_:_:_:_:_:)) Converts an RGBA1010102 32-bit, 4-channel interleaved buffer to an 8-bit-per-channel, 4-channel interleaved buffer with permutation. [`func vImageConvert_RGBA1010102ToARGB16U(UnsafePointer, UnsafePointer, Int32, Int32, UnsafePointer!, vImage_Flags) -> vImage_Error`](/documentation/Accelerate/vImageConvert_RGBA1010102ToARGB16U(_:_:_:_:_:_:)) Converts an RGBA1010102 32-bit, 4-channel interleaved buffer to an unsigned 16-bit-per-channel, 4-channel interleaved buffer with permutation. --- Copyright © 2026 Apple Inc.
