# Applying a flood fill to an image Fill connected components of an image with a new color. ## Topics ### Flood-filling buffers [`func vImageFloodFill_Planar8(UnsafePointer, UnsafeMutableRawPointer!, vImagePixelCount, vImagePixelCount, Pixel_8, Int32, vImage_Flags) -> vImage_Error`](/documentation/Accelerate/vImageFloodFill_Planar8(_:_:_:_:_:_:_:)) Applies a flood-fill operation to an 8-bit planar image. [`func vImageFloodFill_Planar16U(UnsafePointer, UnsafeMutableRawPointer!, vImagePixelCount, vImagePixelCount, Pixel_16U, Int32, vImage_Flags) -> vImage_Error`](/documentation/Accelerate/vImageFloodFill_Planar16U(_:_:_:_:_:_:_:)) Applies a flood fill-operation to an unsigned 16-bit planar image.
