Implementations

impl TextRunPrimitive

pub fn update_font_instance( &mut self, specified_font: &FontInstance, surface: &SurfaceInfo, spatial_node_index: SpatialNodeIndex, transform: &LayoutToWorldTransform, allow_subpixel: bool, raster_space: RasterSpace, spatial_tree: &SpatialTree ) -> bool

fn get_raster_space_for_prim( &self, prim_spatial_node_index: SpatialNodeIndex, low_quality_pinch_zoom: bool, device_pixel_scale: DevicePixelScale, spatial_tree: &SpatialTree ) -> RasterSpace

Gets the raster space to use when rendering this primitive. Usually this would be the requested raster space. However, if the primitive’s spatial node or one of its ancestors is being pinch zoomed then we round it. This prevents us rasterizing glyphs for every minor change in zoom level, as that would be too expensive.

pub fn request_resources( &mut self, prim_offset: LayoutVector2D, specified_font: &FontInstance, glyphs: &[GlyphInstance], transform: &LayoutToWorldTransform, surface: &SurfaceInfo, spatial_node_index: SpatialNodeIndex, allow_subpixel: bool, low_quality_pinch_zoom: bool, resource_cache: &mut ResourceCache, gpu_cache: &mut GpuCache, spatial_tree: &SpatialTree, scratch: &mut PrimitiveScratchBuffer )
