Properties

height

the cropped height

getVideoCropMetaHeight :: MonadIO m => VideoCropMeta -> m Word32

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

get videoCropMeta #height

setVideoCropMetaHeight :: MonadIO m => VideoCropMeta -> Word32 -> m ()

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

set videoCropMeta [ #height := value ]

meta

parent Meta

getVideoCropMetaMeta :: MonadIO m => VideoCropMeta -> m Meta

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

get videoCropMeta #meta

width

the cropped width

getVideoCropMetaWidth :: MonadIO m => VideoCropMeta -> m Word32

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

get videoCropMeta #width

setVideoCropMetaWidth :: MonadIO m => VideoCropMeta -> Word32 -> m ()

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

set videoCropMeta [ #width := value ]

x

the horizontal offset

getVideoCropMetaX :: MonadIO m => VideoCropMeta -> m Word32

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

get videoCropMeta #x

setVideoCropMetaX :: MonadIO m => VideoCropMeta -> Word32 -> m ()

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

set videoCropMeta [ #x := value ]

y

the vertical offset

getVideoCropMetaY :: MonadIO m => VideoCropMeta -> m Word32

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

get videoCropMeta #y

setVideoCropMetaY :: MonadIO m => VideoCropMeta -> Word32 -> m ()

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

set videoCropMeta [ #y := value ]
