Methods

Properties

alpha

No description available in the introspection data.

getFrameCompositionMetaAlpha :: MonadIO m => FrameCompositionMeta -> m Double

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

get frameCompositionMeta #alpha

setFrameCompositionMetaAlpha :: MonadIO m => FrameCompositionMeta -> Double -> m ()

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

set frameCompositionMeta [ #alpha := value ]

height

The desired height of the video. -1 means that no scaling should be applied.

getFrameCompositionMetaHeight :: MonadIO m => FrameCompositionMeta -> m Double

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

get frameCompositionMeta #height

setFrameCompositionMetaHeight :: MonadIO m => FrameCompositionMeta -> Double -> m ()

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

set frameCompositionMeta [ #height := value ]

meta

the parent Meta.

getFrameCompositionMetaMeta :: MonadIO m => FrameCompositionMeta -> m Meta

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

get frameCompositionMeta #meta

operator

The blending operator for the source.

getFrameCompositionMetaOperator :: MonadIO m => FrameCompositionMeta -> m Int32

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

get frameCompositionMeta #operator

setFrameCompositionMetaOperator :: MonadIO m => FrameCompositionMeta -> Int32 -> m ()

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

set frameCompositionMeta [ #operator := value ]

posx

The desired x position.

getFrameCompositionMetaPosx :: MonadIO m => FrameCompositionMeta -> m Double

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

get frameCompositionMeta #posx

setFrameCompositionMetaPosx :: MonadIO m => FrameCompositionMeta -> Double -> m ()

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

set frameCompositionMeta [ #posx := value ]

posy

The desired y position.

getFrameCompositionMetaPosy :: MonadIO m => FrameCompositionMeta -> m Double

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

get frameCompositionMeta #posy

setFrameCompositionMetaPosy :: MonadIO m => FrameCompositionMeta -> Double -> m ()

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

set frameCompositionMeta [ #posy := value ]

width

The desired width of the video. -1 means that no scaling should beapplied applied.

getFrameCompositionMetaWidth :: MonadIO m => FrameCompositionMeta -> m Double

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

get frameCompositionMeta #width

setFrameCompositionMetaWidth :: MonadIO m => FrameCompositionMeta -> Double -> m ()

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

set frameCompositionMeta [ #width := value ]

zorder

The desired z order.

getFrameCompositionMetaZorder :: MonadIO m => FrameCompositionMeta -> m Word32

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

get frameCompositionMeta #zorder

setFrameCompositionMetaZorder :: MonadIO m => FrameCompositionMeta -> Word32 -> m ()

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

set frameCompositionMeta [ #zorder := value ]
