The following shows an 8-bit RGB image converted to a 1-bit planar image with [`vImageConvert_Planar8toPlanar1(_:_:_:_:_:)`](/documentation/Accelerate/vImageConvert_Planar8toPlanar1(_:_:_:_:_:)) using [`kvImageConvert_DitherNone`](/documentation/Accelerate/kvImageConvert_DitherNone):

To learn about converting an RGB image to grayscale, see <doc://com.apple.documentation/documentation/Accelerate/converting-color-images-to-grayscale>.
