◆ AngleAtLength()

double osmscout::LabelPath::AngleAtLength ( double offset ) const

◆ AngleAtLengthDeg()

◆ PointAtLength()

Vertex2D osmscout::LabelPath::PointAtLength ( double offset ) const

◆ TestAngleVariance()

bool osmscout::LabelPath::TestAngleVariance	(	double	startOffset,
		double	endOffset,
		double	maximumAngle ) const

Test how squiggly is path in given offsets. It return true if angle between first path segment (on startOffset) and any following (until endOffset) is lesser than required maximum.

Parameters

startOffset
endOffset
maximumAngle	in radians

Returns: true if angle between first and following segments (between given offsets) is lesser than maximumAngle
