virtual

Output a circle as two elliptical arcs.

Reimplemented from Geom::PathSink.

Definition at line 106 of file path-sink.cpp.

◆ feed() [2/7]

template<typename OutputIterator >

void Geom::PathSink::feed	(	Curve const &	c,
		bool	moveto_initial = `true`
	)

virtual

Reimplemented from Geom::PathSink.

Definition at line 89 of file path-sink.cpp.

◆ feed() [3/7]

template<typename OutputIterator >

void Geom::PathSink::feed ( Ellipse const & e )

virtual

Output an ellipse as two elliptical arcs.

Reimplemented from Geom::PathSink.

Definition at line 108 of file path-sink.cpp.

◆ feed() [4/7]

template<typename OutputIterator >

void Geom::PathIteratorSink< OutputIterator >::feed ( Path const & p )

inlineoverridevirtual

Output a subpath.

Calls the appropriate segment methods according to the contents of the passed subpath. You can override this function. NOTE: if you override only some of the feed() functions, always write this in the derived class:

using PathSink::feed;

Geom::PathSink::feed

virtual void feed(Curve const &c, bool moveto_initial=true)

Definition path-sink.cpp:39

Otherwise the remaining methods will be hidden.

Reimplemented from Geom::PathSink.

◆ feed() [5/7]

template<typename OutputIterator >

void Geom::PathSink::feed ( Path const & p )

virtual

Output a subpath.

using PathSink::feed;

Otherwise the remaining methods will be hidden.

Reimplemented from Geom::PathSink.

Definition at line 99 of file path-sink.cpp.

◆ feed() [6/7]

template<typename OutputIterator >

void Geom::PathSink::feed ( PathVector const & v )

virtual

Output a path.

Calls feed() on each path in the vector. You can override this function.

Reimplemented from Geom::PathSink.

Definition at line 102 of file path-sink.cpp.

◆ feed() [7/7]

template<typename OutputIterator >

void Geom::PathSink::feed ( Rect const & r )

virtual

Output an axis-aligned rectangle, using moveTo, lineTo and closePath.

Reimplemented from Geom::PathSink.

Definition at line 104 of file path-sink.cpp.

◆ flush()

template<typename OutputIterator >

void Geom::PathIteratorSink< OutputIterator >::flush ( )

inlineoverridevirtual

Flush any internal state of the generator.

This call should implicitly finish the current subpath. Calling this method should be idempotent, because the default implementations of path() and pathvector() will call it multiple times in a row.

Implements Geom::PathSink.
