Detailed Description

Vector graphics for both composites and single radar data (polar coordinates).

This class utilizes SVG elements supporting free draw, especially POLYGON and PATH.

As geographic projections distort lines, arcs and angles, Bezier curves (PATH) are used.

Member Function Documentation

◆ cubicBezierTo() [1/2]

void cubicBezierTo	(	drain::svgPATH &	elem,
		double	radiusM,
		double	azimuthStartR,
		double	azimuthEndR
	)		const

Single command to draw arc.

Parameters

drain::Point2D<int> & imgPoint - starting point, should be "already" compatible with (radiusM, azimutthStartR)

◆ cubicBezierTo() [2/2]

void cubicBezierTo	(	drain::svgPATH &	elem,
		drain::Point2D< int > &	imgPoint,
		double	radiusM,
		double	azimuthStartR,
		double	azimuthEndR
	)		const

Parameters

drain::Point2D<int> & imgPoint - starting point, should be "already" compatible with (radiusM, azimutthStartR)

◆ getOverlayStyle()

drain::image::TreeSVG & getOverlayStyle ( drain::image::TreeSVG & svgDoc )

static

Sets some CSS properties applicable in radar graphics (grids, sectors).

Creates a style element only if it does not exist already.

More general style is obtained with RackSVG::getStyle().

◆ updateCartesianConf()

void updateCartesianConf ( const drain::VariableMap & where )

Read meta data related to Cartesian data, that is, geographic configuration of a radar composite.

This command can be used together with configurePolar().

◆ updateRadarConf()

void updateRadarConf ( const drain::VariableMap & where )

Read meta data related to polar coordinates, that is, geographic configuration of a single radar.

This command can be used together with configureCartesian().
