The VECTORARC structure holds information about a vector arc object.

Member	Description
Object	Abstract object.
Point	A VECTORPOINT structure that contains the vertex of a vector arc object, about which the arc sweeps.
Pen	VECTORPEN structure that contains information about the pen to use when drawing the vector arc object.
Radius	Length of the radius of the vector arc object. This value is in logical units.
StartAngle	The angle at which to begin the vector arc. Values should be between 0 and 360 degrees. Values less than 0 and greater than 360 will be modified internally.
SweepAngle	The angle through which to sweep the vector arc. Values should be between 360 and +360 degrees. Positive angles will be drawn in a counter-clockwise direction from StartAngle. Negative angles will be drawn in a clockwise direction.
