Properties

inSize

the input size

getVideoResamplerInSize :: MonadIO m => VideoResampler -> m Int32

Get the value of the “in_size” field. When overloading is enabled, this is equivalent to

get videoResampler #inSize

setVideoResamplerInSize :: MonadIO m => VideoResampler -> Int32 -> m ()

Set the value of the “in_size” field. When overloading is enabled, this is equivalent to

set videoResampler [ #inSize := value ]

maxTaps

the maximum number of taps

getVideoResamplerMaxTaps :: MonadIO m => VideoResampler -> m Word32

Get the value of the “max_taps” field. When overloading is enabled, this is equivalent to

get videoResampler #maxTaps

setVideoResamplerMaxTaps :: MonadIO m => VideoResampler -> Word32 -> m ()

Set the value of the “max_taps” field. When overloading is enabled, this is equivalent to

set videoResampler [ #maxTaps := value ]

nPhases

the number of phases

getVideoResamplerNPhases :: MonadIO m => VideoResampler -> m Word32

Get the value of the “n_phases” field. When overloading is enabled, this is equivalent to

get videoResampler #nPhases

setVideoResamplerNPhases :: MonadIO m => VideoResampler -> Word32 -> m ()

Set the value of the “n_phases” field. When overloading is enabled, this is equivalent to

set videoResampler [ #nPhases := value ]

nTaps

array with new number of taps for each phase

getVideoResamplerNTaps :: MonadIO m => VideoResampler -> m Word32

Get the value of the “n_taps” field. When overloading is enabled, this is equivalent to

get videoResampler #nTaps

setVideoResamplerNTaps :: MonadIO m => VideoResampler -> Word32 -> m ()

Set the value of the “n_taps” field. When overloading is enabled, this is equivalent to

set videoResampler [ #nTaps := value ]

offset

array with the source offset for each output element

getVideoResamplerOffset :: MonadIO m => VideoResampler -> m Word32

Get the value of the “offset” field. When overloading is enabled, this is equivalent to

get videoResampler #offset

setVideoResamplerOffset :: MonadIO m => VideoResampler -> Word32 -> m ()

Set the value of the “offset” field. When overloading is enabled, this is equivalent to

set videoResampler [ #offset := value ]

outSize

the output size

getVideoResamplerOutSize :: MonadIO m => VideoResampler -> m Int32

Get the value of the “out_size” field. When overloading is enabled, this is equivalent to

get videoResampler #outSize

setVideoResamplerOutSize :: MonadIO m => VideoResampler -> Int32 -> m ()

Set the value of the “out_size” field. When overloading is enabled, this is equivalent to

set videoResampler [ #outSize := value ]

phase

array with the phase to use for each output element

getVideoResamplerPhase :: MonadIO m => VideoResampler -> m Word32

Get the value of the “phase” field. When overloading is enabled, this is equivalent to

get videoResampler #phase

setVideoResamplerPhase :: MonadIO m => VideoResampler -> Word32 -> m ()

Set the value of the “phase” field. When overloading is enabled, this is equivalent to

set videoResampler [ #phase := value ]

taps

the taps for all phases

getVideoResamplerTaps :: MonadIO m => VideoResampler -> m Double

Get the value of the “taps” field. When overloading is enabled, this is equivalent to

get videoResampler #taps

setVideoResamplerTaps :: MonadIO m => VideoResampler -> Double -> m ()

Set the value of the “taps” field. When overloading is enabled, this is equivalent to

set videoResampler [ #taps := value ]
