Member Function Documentation

Doc * cinder::svg::Node::getDoc ( ) const

Returns the svg::Doc this Node is an element of.

const Node* cinder::svg::Node::getParent ( ) const

Returns the immediate parent of this node.

const std::string& cinder::svg::Node::getId ( ) const

Returns the ID of this Node when present.

string cinder::svg::Node::getDomPath ( ) const

Returns a DOM-style path to this node.

const Style& cinder::svg::Node::getStyle ( ) const

Returns the style elements defined on this Node but not inherited from ancestors.

void cinder::svg::Node::setStyle ( const Style style)

Sets the style defined on this Node but not inherited from ancestors.

Style cinder::svg::Node::calcInheritedStyle ( ) const

Returns the node's Style, including attributes inherited from its ancestors for attributes it does not specify.

virtual bool cinder::svg::Node::containsPoint ( const vec2 &  pt) const
virtual

Returns whether the point pt is inside of the Node's shape.

Reimplemented in cinder::svg::Image, cinder::svg::Polyline, cinder::svg::Polygon, cinder::svg::Rect, cinder::svg::Path, cinder::svg::Ellipse, and cinder::svg::Circle.

void cinder::svg::Node::render ( Renderer renderer) const

Renders the node and its descendants.

const Node * cinder::svg::Node::findInAncestors ( const std::string &  elementId) const
virtual

Finds the node with ID elementId amongst this Node's ancestors. Returns NULL on failure.

Reimplemented in cinder::svg::Group.

Paint cinder::svg::Node::findPaintInAncestors ( const std::string &  paintName) const

Finds the svg::Paint node with ID elementId amongst this Node's ancestors. Returns a default svg::Paint instance on failure.

bool cinder::svg::Node::specifiesTransform ( ) const

Returns whether this Node specifies a transformation.

mat3 cinder::svg::Node::getTransform ( ) const

Returns the local transformation of this node. Returns identity if the Node's transform isn't specified.

void cinder::svg::Node::setTransform ( const mat3 &  transform)

Sets the local transformation of this node.

void cinder::svg::Node::unspecifyTransform ( )

Removes the local transformation of this node, effectively making it the identity matrix.

mat3 cinder::svg::Node::getTransformInverse ( ) const

Returns the inverse of the local transformation of this node. Returns identity if the Node's transform isn't specified.

mat3 cinder::svg::Node::getTransformAbsolute ( ) const

Returns the absolute transformation of this node, which includes inherited transformations.

mat3 cinder::svg::Node::getTransformAbsoluteInverse ( ) const

Returns the inverse of the absolute transformation of this node, which includes inherited transformations.

Rectf cinder::svg::Node::getBoundingBox ( ) const

Returns the local bounding box of the Node. Calculated and cached the first time it is requested.

Rectf cinder::svg::Node::getBoundingBoxAbsolute ( ) const

Returns the absolute bounding box of the Node. Calculated and cached the first time it is requested.

virtual Shape2d cinder::svg::Node::getShape ( ) const
virtual
Shape2d cinder::svg::Node::getShapeAbsolute ( ) const

Returns a Shape2d representing the node in absolute coordinates. Not supported for Text.

const Paint & cinder::svg::Node::getFill ( ) const

Returns node's fill, or the first among its ancestors when it has none.

const Paint & cinder::svg::Node::getStroke ( ) const

Returns node's stroke, or the first among its ancestors when it has none.

float cinder::svg::Node::getOpacity ( ) const

Returns node's opacity, or the first among its ancestors when it has none.

float cinder::svg::Node::getFillOpacity ( ) const

Returns node's fill opacity, or the first among its ancestors when it has none.

float cinder::svg::Node::getStrokeOpacity ( ) const

Returns node's stroke opacity, or the first among its ancestors when it has none.

FillRule cinder::svg::Node::getFillRule ( ) const

Returns node's fill rule, or the first among its ancestors when it has none.

LineCap cinder::svg::Node::getLineCap ( ) const

Returns node's line cap, or the first among its ancestors when it has none.

LineJoin cinder::svg::Node::getLineJoin ( ) const

Returns node's line join, or the first among its ancestors when it has none.

float cinder::svg::Node::getStrokeWidth ( ) const

Returns node's stroke width, or the first among its ancestors when it has none.

const vector< string > & cinder::svg::Node::getFontFamilies ( ) const

Returns node's font families, or the first among its ancestors when it has none.

Value cinder::svg::Node::getFontSize ( ) const

Returns node's font size, or the first among its ancestors when it has none.

bool cinder::svg::Node::isVisible ( ) const

Returns whether this Node is visible, or the first among its ancestors when unspecified.

bool cinder::svg::Node::isDisplayNone ( ) const

Returns whether the Display property of this Node is set to 'None', preventing rendering of the node and its children.
