Member Function Documentation

◆ begin()

Iter CartoType::TContour::begin ( ) const

inline

Returns a constant iterator positioned at the start of the points.

◆ begin_lines()

LineIter CartoType::TContour::begin_lines ( ) const

inline

Returns a constant iterator positioned at the start of the lines.

◆ Closed()

bool CartoType::TContour::Closed ( ) const

inlineoverridevirtual

Returns true if this is a closed contour.

Implements CartoType::MContour.

◆ Contour()

TContour CartoType::TContour::Contour ( size_t aIndex ) const

inlineoverridevirtual

Returns the contour indexed by aIndex.

Implements CartoType::MPath.

◆ end()

Iter CartoType::TContour::end ( ) const

inline

Returns a constant iterator positioned at the end of the points.

◆ end_lines()

LineIter CartoType::TContour::end_lines ( ) const

inline

Returns a constant iterator positioned at the end of the lines.

◆ MayHaveCurves()

bool CartoType::TContour::MayHaveCurves ( ) const

inlineoverridevirtual

Returns true if the path may have off-curve points.

Implements CartoType::MPath.

◆ OutlinePointData()

const TOutlinePoint * CartoType::TContour::OutlinePointData ( ) const

inline

Returns a pointer to start of the TOutlinePoint data if this contour may have off-curve points, otherwise returns null.

◆ Point()

TOutlinePoint CartoType::TContour::Point ( size_t aIndex ) const

inlineoverridevirtual

Returns a point selected by its index.

Implements CartoType::MContour.

◆ PointData()

const TPoint * CartoType::TContour::PointData ( ) const

inline

Returns a pointer to start of the TPoint data if this contour has only on-curve points, otherwise returns null.

◆ Points()

size_t CartoType::TContour::Points ( ) const

inlineoverridevirtual

Returns the number of points in the contour.

Implements CartoType::MContour.

◆ SubContour()

TContour CartoType::TContour::SubContour	(	size_t	aStart,
		size_t	aPoints
	)

inline

Returns a sub-contour of this contour, starting at the point indexed by aStart, and containing aPoints points.

◆ Traverse()

template<class MTraverser >

void CartoType::TContour::Traverse	(	MTraverser &	aTraverser,
		const TRect *	aClip = `nullptr`
	)		const

inline

Traverses this contour, calling the functions defined by aTraverser to handle moves, lines, and curves. Clips the output to aClip if aClip is non-null.
