donner::svg::components::TransformComponent

struct donner::svg::components::TransformComponent

Stores the raw transform value set on an entity, for the transform presentation attribute.

This can be sourced from the transform="..." XML attribute, or from the transform CSS property.

Class Members
Property< CssTransform >	transform	Value of the transform, if it is set. Defaults to std::nullopt. Represents the entity-from-parent transform.

donner::svg::components::ComputedLocalTransformComponent

struct donner::svg::components::ComputedLocalTransformComponent

Stores the computed transform value for an entity, relative to the parent.

This resolves presentation attributes and the CSS cascade and stores the resulting value for the current entity.

Collaboration diagram for donner::svg::components::ComputedLocalTransformComponent:

Class Members
Transformd	entityFromParent	Transform from the entity from its parent.
CssTransform	rawCssTransform	Raw CSS transform value, before resolving percentages relative to the viewport.
Vector2d	transformOrigin	Resolved transform origin in pixels.

donner::svg::components::ComputedAbsoluteTransformComponent

struct donner::svg::components::ComputedAbsoluteTransformComponent

Stores the computed transform value for an entity, relative to the world.

This applies the transform from the from all parent entities, and represents the transform of the entity from the root.

Class Members
Transformd	entityFromWorld	Transform from the entity from the world.
