OEDrawCurvedArrow¶

void OEDrawCurvedArrow(OEImageBase& image, const OE2DPoint& center,
                       double bgnAngle, double endAngle, double radius,
                       bool clockwise, const OEPen& pen);

Draws a curved arrow. See example in Figure: Example of drawing curved arrows.

Example of drawing curved arrows¶

image: The image in which the arrow is drawn.
center: The center of the arc.
bgnAngle, endAngle: The two endpoints of the arc (in degrees). Both angles are in degrees and their values have to be in a range of \([0.0^{\circ}, 360.0^{\circ}]\). Angles are interpreted such that \(0.0^{\circ}\) and \(360.0^{\circ}\) degrees are at the 12 o’clock position, \(90.0^{\circ}\) degrees corresponds to 3 o’clock, etc.
radius: The radius of the arc.
clockwise: The direction of the arrow.
pen: The graphical properties of the curved arrow.
