|
|
int | drawOrder = 0 |
| | The draw order of the element, computed from the traversal order of the tree.
|
|
Entity | subtreeLastEntity = entt::null |
| | Last rendered descendant, including this instance when it has no rendered children.
|
|
bool | visible = true |
| | Whether the element is visible. Note that elements may still influence rendering behavior when they are hidden, such as <pattern> elements.
|
|
bool | isolatedLayer = false |
| | True if this instance establishes a new rendering layer, such as if there is opacity.
|
|
Transform2d | worldFromEntityTransform |
| | Cascaded transform mapping entity-local coords to canvas coords. Applying this to a <circle>'s (cx, cy) yields that circle's canvas position. Composed with RendererDriver::surfaceFromCanvasTransform_ as worldFromEntityTransform * surfaceFromCanvasTransform_ (donner's left-first operator*: "apply entity→world, then world→surface") to form the final render CTM.
|
|
std::optional< Box2d > | clipRect |
| | The clip rect of the element, if set.
|
|
std::optional< ResolvedClipPath > | clipPath |
| | The clip path of the element, if set.
|
|
std::optional< ResolvedMask > | mask |
| | The mask of the element, if set.
|
|
std::optional< ResolvedMarker > | markerStart |
| | The resolved marker for marker-start, if any.
|
|
std::optional< ResolvedMarker > | markerMid |
| | The resolved marker for marker-mid, if any.
|
|
std::optional< ResolvedMarker > | markerEnd |
| | The resolved marker for marker-end, if any.
|
|
Entity | dataEntity = entt::null |
| | The entity containing the structural components of the instance, element-specific components like IdComponent.
|
| Entity | textSpanRoot = entt::null |
| | Set when this instance paints part of a text element rather than its own geometry: the root <text> entity whose laid-out spans it draws.
|
|
ResolvedPaintServer | resolvedFill = PaintServer::None() |
| | The resolved paint server for the instance's fill, if any.
|
|
ResolvedPaintServer | resolvedStroke = PaintServer::None() |
| | The resolved paint server for the instance's stroke, if any.
|
|
std::optional< ResolvedFilterEffect > | resolvedFilter |
| | The resolved filter effect on this instance, if any.
|
|
std::optional< SubtreeInfo > | subtreeInfo |
| | Information about this elements subtree, if there is a rendering-influencing subtree attached to this entity.
|
An instance of the entity in the rendering tree.
Each renderered entity has an instance with a unique drawOrder, which enables this list to be sorted and traversed to render the tree.
| Entity donner::svg::components::RenderingInstanceComponent::textSpanRoot = entt::null |
Set when this instance paints part of a text element rather than its own geometry: the root <text> entity whose laid-out spans it draws.
A <tspan> or <textPath> that carries clip-path, mask, or filter becomes its own instance so those effects get their own layer, while dataEntity stays the span so objectBoundingBox effect regions resolve against the span's own box. The text root's instance paints every span that no such instance claims. A span nested inside a claimed span is painted by the outer instance, so its own effects are not applied yet, and a claimed span paints after the text root's remaining spans rather than in document order. A <use> copy has no span instances of its own, so it paints every span without the span-level effects.
