donner::svg::components::SizedElementComponent

struct donner::svg::components::SizedElementComponent

Stores the properties of a sized element, x, y, width, height.

Used for <svg>, <image> and <foreignObject> by the standard, and also internally with <use> for Donner.

Class Members
bool	applyTranslationForUseElement = false	Set to true for <use> elements, so that x/y are applied as a translation.
bool	canOverrideWidthHeightForSymbol = false	Set to true for <symbol> elements, so that width/height are inherited from the <use> element.
SizedElementProperties	properties	The properties of the sized element, x, y, width, height.

donner::svg::components::ComputedSizedElementComponent

struct donner::svg::components::ComputedSizedElementComponent

Stores the computed bounds of a sized element, resolving units and percentages.

Contains the computed rect and inherited viewBox of the parent element.

Class Members
Box2d	bounds	The computed rect of this sized element.
Box2d	inheritedViewBox	The viewBox of the parent element, used for preserveAspectRatio transformations.

donner::svg::components::ComputedShadowSizedElementComponent

struct donner::svg::components::ComputedShadowSizedElementComponent

Stores a shadow tree's computed SizedElementComponent, where a <use> element overrides the width or height on <symbol> or <svg> which use SizedElementComponent.

From https://www.w3.org/TR/SVG2/struct.html#UseElement:

The width and height attributes only have an effect if the referenced element defines a viewport (i.e., if it is a 'svg' or 'symbol'); if so, a value other than auto for the 'use' element overrides the value of the corresponding geometric property on that element.

Class Members
Box2d	bounds	The computed rect of this sized element.
