GI.GstVideo.Structs.VideoDither

Contents

Description

GstVideoDither provides implementations of several dithering algorithms that can be applied to lines of video pixels to quantize and dither them.

Synopsis

newtype VideoDither = VideoDither (ManagedPtr VideoDither)
videoDitherFree :: (HasCallStack, MonadIO m) => VideoDither -> m ()
videoDitherLine :: (HasCallStack, MonadIO m) => VideoDither -> Ptr () -> Word32 -> Word32 -> Word32 -> m ()

Exported types

Memory-managed wrapper type.

Methods

Arguments

Free dither

Arguments

:: (HasCallStack, MonadIO m)
=> VideoDither	`dither`: a `VideoDither`
-> Ptr ()	`line`: pointer to the pixels of the line
-> Word32	`x`: x coordinate
-> Word32	`y`: y coordinate
-> Word32	`width`: the width
-> m ()

Dither width pixels starting from offset x in line using dither.

y is the line number of line in the output image.
