Inheritance diagram for canvascv::Ellipse:

Public Member Functions
virtual const char *	getType () const
	getType is always implemented by derived to return the same static pointer per shape. More...
Public Member Functions inherited from canvascv::Rectangle
cv::RotatedRect	getRect () const
	get the OpenCV representation of this shape
void	setRect (const cv::RotatedRect &rect)
	set this shape from the OpenCV representation
virtual bool	keyPressed (int &key)
	keyPressed will be called by Canvas for active shapes More...
bool	isPointInRectangle (cv::Point pos)
	returns true if pos is in the rectangle representated by this shape
virtual bool	isAtPos (const cv::Point &pos)
	returns true if shape is at pos, false otherwise
virtual std::list< Handle * >	getConnectionTargets ()
	getConnectionTargets More...
Public Member Functions inherited from canvascv::CompoundShape
virtual void	setOutlineColor (const cv::Scalar &value)
	set the outline color
virtual void	setFillColor (const cv::Scalar &value)
	set the fill color (fill color is not very useful for shapes right now)
virtual void	setThickness (int value)
	set line thickness to use when drawing
virtual void	setLineType (int value)
	set the line type (LINE_4, LINE_8, LINE_AA)
virtual void	setLocked (bool value)
	set the shape lock state (can/can't be moved/edited)
virtual void	setVisible (bool value)
	set the shape visible state
virtual std::shared_ptr< Shape >	getShape (int id)
	getShape More...
Public Member Functions inherited from canvascv::Shape
	Shape ()
	constructor
	Shape (const Shape &other)
	copy constructor
virtual	~Shape ()
	virtual destructor
void	notifyOnEvent (CBPerShape cb)
	used to register for notifications on shape More...
cv::Scalar	getOutlineColor () const
	get the outline color
cv::Scalar	getFillColor () const
	get the fill color (fill color is not very useful for shapes right now)
bool	getLocked () const
	is the shape locked (can't be moved/edited)
bool	getVisible () const
	is the shape visible
int	getThickness () const
	get line thickness to use when drawing
int	getLineType () const
	get the line type (LINE_4, LINE_8, LINE_AA)
int	getId ()
	return a unique id for this shape

Additional Inherited Members
Public Types inherited from canvascv::Shape
typedef std::function< void(Shape *, Event)>	CBPerShape
	signature of a callback which gets the Event
Protected Member Functions inherited from canvascv::Rectangle
virtual void	draw (cv::Mat &canvas)
	draw shape on the canvas More...

	mouseMoved More...
virtual bool	mouseReleased (const cv::Point &pos)
	mouseReleased More...
Protected Member Functions inherited from canvascv::CompoundShape
virtual void	lostFocus ()
	lostFocus is called by Canvas if we're in it and just became non-active
Protected Member Functions inherited from canvascv::Shape
void	drawHelper (cv::Mat &canvas, Shape *other)
	helper method for non compund shapes to draw their members

Detailed Description

Allows you to draw a rotatable ellipse by mouse or from code

Examples:
