Struct webrender::scene_building::PictureChainBuilder

struct PictureChainBuilder {
    current: PictureSource,
    spatial_node_index: SpatialNodeIndex,
    flags: PrimitiveFlags,
    raster_space: RasterSpace,
    set_resolve_target: bool,
    establishes_sub_graph: bool,
}

Helper struct to build picture chains during scene building from a flattened stacking context struct.

Fields

current: PictureSource

The current input source for the next picture

spatial_node_index: SpatialNodeIndex

Positioning node for this picture chain

flags: PrimitiveFlags

Prim flags for any pictures in this chain

raster_space: RasterSpace

Requested raster space for enclosing stacking context

set_resolve_target: bool

If true, set first picture as a resolve target

establishes_sub_graph: bool

If true, mark the last picture as a sub-graph

Implementations

impl PictureChainBuilder

fn from_prim_list( prim_list: PrimitiveList, flags: PrimitiveFlags, spatial_node_index: SpatialNodeIndex, raster_space: RasterSpace, is_sub_graph: bool ) -> Self

Create a new picture chain builder, from a primitive list

fn from_instance( instance: PrimitiveInstance, flags: PrimitiveFlags, spatial_node_index: SpatialNodeIndex, raster_space: RasterSpace ) -> Self

Create a new picture chain builder, from a picture wrapper instance

fn add_picture( self, composite_mode: PictureCompositeMode, clip_node_id: ClipNodeId, context_3d: Picture3DContext<OrderedPictureChild>, interners: &mut Interners, prim_store: &mut PrimitiveStore, prim_instances: &mut Vec<PrimitiveInstance>, clip_tree_builder: &mut ClipTreeBuilder ) -> PictureChainBuilder

Wrap the existing content with a new picture with the given parameters

fn finalize( self, clip_node_id: ClipNodeId, interners: &mut Interners, prim_store: &mut PrimitiveStore, clip_tree_builder: &mut ClipTreeBuilder ) -> PrimitiveInstance

Finish building this picture chain. Set the clip chain on the outermost picture

fn has_picture(&self) -> bool

Returns true if this builder wraps a picture
