Detailed Description

Wrapper for an OGRFeature representing a Line.

Constructor & Destructor Documentation

◆ LineFeature()

LineFeature::LineFeature	(	OGRFeature *	feature,
		OGRGeometry *	linestring
	)

Construct a LineFeature with a feature that can contain any geometry (usually used for MultiLineStrings) - it is not accessed, the geometry is given as a separate LineString parameter instead.

Member Function Documentation

◆ get_line_point()

std::vector< double > LineFeature::get_line_point ( int index )

Return the point in the line at the given index as a std::vector with 3 double entries (3D vector). The index must be between 0 and get_point_count()-1.

◆ get_line_point_x()

double LineFeature::get_line_point_x ( int index )

Get the individual x, y and z components from the line point at the given index. The same can be accomplished with the get_line_point function, but this one works without special std types.

◆ set_line_point()

void LineFeature::set_line_point	(	int	index,
		double	x,
		double	y,
		double	z = `0.0`
	)

Set the coordinates of the point at the given index. Note that the point must exist, otherwise nothing is done. If necessary, create new points with set_point_count before calling this. The z coordinate is optional, it defaults to 0.0.

◆ set_point_count()

void LineFeature::set_point_count ( int new_count )

Set the number of points within the line. Removes or adds new points depending on the previous size.
