Implementations

impl<'a> BackgroundPainter<'a>

pub(super) fn painting_area( &self, fragment_builder: &'a BuilderForBoxFragment<'_>, builder: &mut DisplayListBuilder<'_>, layer_index: usize, ) -> LayoutRect

Get the painting area for this background, which is the actual rectangle in the current coordinate system that the background will be painted.

fn clip( &self, fragment_builder: &'a BuilderForBoxFragment<'_>, builder: &mut DisplayListBuilder<'_>, layer_index: usize, ) -> Option<ClipChainId>

pub(super) fn common_properties( &self, fragment_builder: &'a BuilderForBoxFragment<'_>, builder: &mut DisplayListBuilder<'_>, layer_index: usize, painting_area: LayoutRect, ) -> CommonItemProperties

Get the wr::CommonItemProperties for this background. This includes any clipping established by border radii as well as special clipping and spatial node assignment necessary for background-attachment.

pub(super) fn positioning_area( &self, fragment_builder: &'a BuilderForBoxFragment<'_>, layer_index: usize, ) -> LayoutRect

Get the positioning area of the background which is the rectangle that defines where the origin of the background content is, regardless of where the background is actual painted.
