Member Function Documentation

moveTo()

virtual void CDPL::Vis::Path2DConverter::moveTo ( double  x, double  y  )

pure virtual

Called when a Vis::Path2D element created by a Vis::Path2D::moveTo() call is encountered.

Parameters

x	The x-coordinate of the newly set current position.
y	The y-coordinate of the newly set current position.

arcTo()

virtual void CDPL::Vis::Path2DConverter::arcTo ( double  cx, double  cy, double  rx, double  ry, double  start_ang, double  sweep  )

pure virtual

Called when a Vis::Path2D element created by a Vis::Path2D::arcTo() call is encountered.

Parameters

cx	The x-coordinate of the ellipse center.
cy	The y-coordinate of the ellipse center.
rx	The x-radius of the ellipse.
ry	The y-radius of the ellipse.
start_ang	The start angle of the arg in degrees.
sweep	The length of the arg in degrees.

lineTo()

virtual void CDPL::Vis::Path2DConverter::lineTo ( double  x, double  y  )

pure virtual

Called when a Vis::Path2D element created by a Vis::Path2D::lineTo() call is encountered.

Parameters

x	Specifies the x-coordinate of the line's end point.
y	Specifies the y-coordinate of the line's end point.

closePath()

virtual void CDPL::Vis::Path2DConverter::closePath ( )

pure virtual

Called when a Vis::Path2D element created by a Vis::Path2D::closePath() call is encountered.
