Class Documentation

donner::svg::components::DeferredDecodedImageComponent

struct donner::svg::components::DeferredDecodedImageComponent

A decoded image waiting for enough recoverable document-family capacity.

Class Members
RcString	href	Image reference whose decode was deferred.
size_t	requiredBytes = 0	Exact decoded RGBA bytes required for admission.

donner::svg::components::ImageComponent

struct donner::svg::components::ImageComponent

Parameters for the <image> element.

Class Members
RcString	href	URI to the image resource, which can either be a file path, URL, or data URL (e.g. "data:image/png;base64,...").

donner::svg::components::LoadedSVGImageComponent

struct donner::svg::components::LoadedSVGImageComponent

Loaded SVG sub-document, created from a ImageComponent when the href references an SVG file (image/svg+xml).

Stores the shared internal document handle used by SVGDocument.

Class Members
SVGDocumentHandle	subDocument	Parsed external SVG sub-document handle.

donner::svg::components::ExternalUseComponent

struct donner::svg::components::ExternalUseComponent

Loaded external SVG sub-document referenced by a <use> element.

When a <use> element's href points to an external SVG file, the document is loaded via SubDocumentCache and stored here as an SVGDocumentHandle for rendering as a nested sub-document.

Class Members
RcString	fragment	Fragment identifier within the external document (e.g., "elementId" from "file.svg#elementId"). Empty if the whole document is referenced.
SVGDocumentHandle	subDocument	Parsed external SVG sub-document handle.
