donner::svg::components::SubtreeInfo

struct donner::svg::components::SubtreeInfo

Created on the start of a subtree, to inform the renderer about which element ends the current subtree, plus how many isolated layers need to be popped when the subtree is complete.

Class Members
Entity	firstRenderedEntity	Indicates the first entity within the current subtree. The renderer will continue rendering entities until it reaches this one, then it will pop restorePopDepth isolated layers from the render state.
Entity	lastRenderedEntity	Indicates the last entity within the current subtree. The renderer will continue rendering entities until it reaches this one, then it will pop restorePopDepth isolated layers from the render state.
int	restorePopDepth = 0	How many isolated layers to pop after rendering this entity.

donner::svg::components::PaintResolvedReference

struct donner::svg::components::PaintResolvedReference

Contains rendering information for a paint server, such as the subtree needed if it establishes an isolated layer, and where the paint server is located.

Collaboration diagram for donner::svg::components::PaintResolvedReference:

Class Members
optional< Color >	fallback	Fallback color to use if this paint fails to instantiate. This can happen for various reasons, such as if a gradient has no stops (making it invalid).
ResolvedReference	reference	Reference to the paint server element.
optional< SubtreeInfo >	subtreeInfo	If this paint server creates a subtree, such as for patterns, contains subtree info to inform the renderer how to render it.
