pulp::canvas::VectorScene Class Reference

#include <scene.hpp>

Public Member Functions
	VectorScene ()
SceneGroup &	root ()
const SceneGroup &	root () const
void	set_root (std::unique_ptr< SceneGroup > r)
	Replace the root group entirely (e.g. after a fresh SVG import).
void	paint (Canvas &canvas)
	Walk + paint the entire scene to canvas.
SceneRect	take_dirty_rect ()
	Returns the union of "old painted bounds" and "new transformed bounds" for every node that mutated since the last paint, then resets the internal pending-dirty tracker.
SceneRect	peek_dirty_rect () const
	Peek without resetting — useful for diagnostics + tests.
void	note_node_dirtied (const SceneNode &node)
	Called by SceneNode::mark_dirty() when a node mutates; unions the node's "old + new" bounds into the pending dirty rect.

Static Public Member Functions
static VectorScene	from_svg_string (const std::string &svg_data)
	Parse an SVG document string and produce a populated VectorScene.
static VectorScene	from_svg_file (const std::string &path)
	Convenience: load an SVG file and return a populated scene.

Member Function Documentation

from_svg_file()

VectorScene pulp::canvas::VectorScene::from_svg_file ( const std::string & path )

static

Convenience: load an SVG file and return a populated scene.

from_svg_string()

VectorScene pulp::canvas::VectorScene::from_svg_string ( const std::string & svg_data )

static

Parse an SVG document string and produce a populated VectorScene.

Reuses the existing nanosvg parser; visible cubic-Bezier shapes become ScenePath nodes parented to the returned scene's root SceneGroup. Fill / stroke / opacity / fill-rule are translated. Returns an empty (root-only) scene if parsing fails.

note_node_dirtied()

void pulp::canvas::VectorScene::note_node_dirtied

(

const SceneNode &

node

)

Called by SceneNode::mark_dirty() when a node mutates; unions the node's "old + new" bounds into the pending dirty rect.

paint()

void pulp::canvas::VectorScene::paint

(

Canvas &

canvas

)

Walk + paint the entire scene to canvas.

Captures each node's painted scene-space bounds so the next take_dirty_rect() call can report exact repaint extents.

peek_dirty_rect()

SceneRect pulp::canvas::VectorScene::peek_dirty_rect ( ) const

inline

Peek without resetting — useful for diagnostics + tests.

root() [1/2]

SceneGroup & pulp::canvas::VectorScene::root ( )

inline

root() [2/2]

const SceneGroup & pulp::canvas::VectorScene::root ( ) const

inline

set_root()

void pulp::canvas::VectorScene::set_root ( std::unique_ptr< SceneGroup > r )

inline

Replace the root group entirely (e.g. after a fresh SVG import).

take_dirty_rect()

SceneRect pulp::canvas::VectorScene::take_dirty_rect

(

)

Returns the union of "old painted bounds" and "new transformed bounds" for every node that mutated since the last paint, then resets the internal pending-dirty tracker.

Empty rect ⇒ nothing to repaint.
