GI.GstVideo.Structs.VideoAlignment

Extra alignment parameters for the memory of video buffers. This structure is usually used to configure the bufferpool if it supports the BUFFER_POOL_OPTION_VIDEO_ALIGNMENT.

Exported types

Methods

new :: MonadIO m => (ManagedPtr VideoAlignment -> VideoAlignment) -> [AttrOp VideoAlignment tag] -> m VideoAlignment

newZeroVideoAlignment :: MonadIO m => m VideoAlignment

Construct a VideoAlignment struct initialized to zero.

noVideoAlignment :: Maybe VideoAlignment

A convenience alias for Nothing :: Maybe VideoAlignment.

Methods

reset

videoAlignmentReset

Arguments

:: (HasCallStack, MonadIO m)

=> VideoAlignment

align: a VideoAlignment

-> m ()

Set align to its default values with no padding and no alignment.

Properties

paddingBottom

extra pixels on the bottom

getVideoAlignmentPaddingBottom :: MonadIO m => VideoAlignment -> m Word32

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

get videoAlignment #paddingBottom

setVideoAlignmentPaddingBottom :: MonadIO m => VideoAlignment -> Word32 -> m ()

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

set videoAlignment [ #paddingBottom := value ]

paddingLeft

extra pixels on the left side

getVideoAlignmentPaddingLeft :: MonadIO m => VideoAlignment -> m Word32

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

get videoAlignment #paddingLeft

setVideoAlignmentPaddingLeft :: MonadIO m => VideoAlignment -> Word32 -> m ()

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

set videoAlignment [ #paddingLeft := value ]

paddingRight

extra pixels on the right side

getVideoAlignmentPaddingRight :: MonadIO m => VideoAlignment -> m Word32

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

get videoAlignment #paddingRight

setVideoAlignmentPaddingRight :: MonadIO m => VideoAlignment -> Word32 -> m ()

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

set videoAlignment [ #paddingRight := value ]

paddingTop

extra pixels on the top

getVideoAlignmentPaddingTop :: MonadIO m => VideoAlignment -> m Word32

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

get videoAlignment #paddingTop

setVideoAlignmentPaddingTop :: MonadIO m => VideoAlignment -> Word32 -> m ()

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

set videoAlignment [ #paddingTop := value ]
