Detailed Description

Special MouseHandler Implementation that allows for defining a quadrangle.

The resulting quadrangle (defined by it's four corners points) can be restricted to be always convex. The quadrangle is initialized as a rectangle that is 20 px smaller than the given max-size rectangle.

Constructor & Destructor Documentation

◆ DefineQuadrangleMouseHandler() [1/2]

icl::qt::DefineQuadrangleMouseHandler::DefineQuadrangleMouseHandler ( )

empty constructor (creates a null handler)

◆ DefineQuadrangleMouseHandler() [2/2]

icl::qt::DefineQuadrangleMouseHandler::DefineQuadrangleMouseHandler	(	const utils::Size &	maxSize,
		bool	convexOnly = `true`
	)

constructor with given max size

The maxSize must be identical to the image the mousehandler is used as a overlay with. Convex means that the quadrangle is convex and that its opposing edges do not intersect

◆ ~DefineQuadrangleMouseHandler()

virtual icl::qt::DefineQuadrangleMouseHandler::~DefineQuadrangleMouseHandler ( )

virtual

destructor

Member Function Documentation

◆ getQuadrangle()

std::vector<utils::Point> icl::qt::DefineQuadrangleMouseHandler::getQuadrangle ( ) const

returns the current quadrangle

◆ init()

void icl::qt::DefineQuadrangleMouseHandler::init	(	const utils::Size &	maxSize,
		bool	convexOnly = `true`
	)

deferred intialization method

◆ isNull()

bool icl::qt::DefineQuadrangleMouseHandler::isNull ( ) const

inline

returns whether this mousehandler has been initialized yet

◆ process()

virtual void icl::qt::DefineQuadrangleMouseHandler::process ( const qt::MouseEvent & e )

virtual

MouseHandler interface.

Reimplemented from icl::qt::MouseHandler.

◆ setHandleSize()

void icl::qt::DefineQuadrangleMouseHandler::setHandleSize ( float size )

sets the size of the handles

◆ setOffset()

void icl::qt::DefineQuadrangleMouseHandler::setOffset ( const utils::Point & p )

sets an offset that shifts both in- and outputs

◆ setQuadrangle()

void icl::qt::DefineQuadrangleMouseHandler::setQuadrangle ( const utils::Point ps[4] )

sets the current quadrangle

If the given quadrangle is not completely covered by the image rect, or the convexOnly flag is activated and the given quadrangle is not convex, an exception is thrown

◆ vis()

utils::VisualizationDescription icl::qt::DefineQuadrangleMouseHandler::vis ( ) const

returns a visualization
