Methods

Properties

height

No description available in the introspection data.

getVideoTileInfoHeight :: MonadIO m => VideoTileInfo -> m Word32

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

get videoTileInfo #height

setVideoTileInfoHeight :: MonadIO m => VideoTileInfo -> Word32 -> m ()

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

set videoTileInfo [ #height := value ]

size

The size in bytes of a tile. This value must be divisible by VideoTileInfo.stride.

Since: 1.22

getVideoTileInfoSize :: MonadIO m => VideoTileInfo -> m Word32

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

get videoTileInfo #size

setVideoTileInfoSize :: MonadIO m => VideoTileInfo -> Word32 -> m ()

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

set videoTileInfo [ #size := value ]

stride

The stride (in bytes) of a tile line. Regardless if the tile have sub-tiles this stride multiplied by the height should be equal to VideoTileInfo.size. This value is used to translate into linear stride when older APIs are being used to expose this format.

Since: 1.22

getVideoTileInfoStride :: MonadIO m => VideoTileInfo -> m Word32

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

get videoTileInfo #stride

setVideoTileInfoStride :: MonadIO m => VideoTileInfo -> Word32 -> m ()

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

set videoTileInfo [ #stride := value ]

width

The width in pixels of a tile. This value can be zero if the number of pixels per line is not an integer value.

Since: 1.22

getVideoTileInfoWidth :: MonadIO m => VideoTileInfo -> m Word32

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

get videoTileInfo #width

setVideoTileInfoWidth :: MonadIO m => VideoTileInfo -> Word32 -> m ()

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

set videoTileInfo [ #width := value ]
