Description

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.

Synopsis

newtype VideoAlignment = VideoAlignment (ManagedPtr VideoAlignment)
newZeroVideoAlignment :: MonadIO m => m VideoAlignment
videoAlignmentReset :: (HasCallStack, MonadIO m) => VideoAlignment -> m ()
getVideoAlignmentPaddingBottom :: MonadIO m => VideoAlignment -> m Word32
setVideoAlignmentPaddingBottom :: MonadIO m => VideoAlignment -> Word32 -> m ()
getVideoAlignmentPaddingLeft :: MonadIO m => VideoAlignment -> m Word32
setVideoAlignmentPaddingLeft :: MonadIO m => VideoAlignment -> Word32 -> m ()
getVideoAlignmentPaddingRight :: MonadIO m => VideoAlignment -> m Word32
setVideoAlignmentPaddingRight :: MonadIO m => VideoAlignment -> Word32 -> m ()
getVideoAlignmentPaddingTop :: MonadIO m => VideoAlignment -> m Word32
setVideoAlignmentPaddingTop :: MonadIO m => VideoAlignment -> Word32 -> m ()

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 Source #

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 () Source #

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 Source #

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 () Source #

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 Source #

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 () Source #

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 Source #

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 () Source #

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

set videoAlignment [ #paddingTop := value ]
