Draws a circle arc or an ellipse arc in a variable of type picLayer. The arc is drawn counterclockwise.
Example
MonImage is WDPic = "Test.gif"
MonCalque is picLayer

// Dessin d'un arc de cercle jaune clair sur le calque
MonCalque.DessineArc(10, 10, 50, 50, 20, 20, 40, 50, LightYellow)

IMG_MonDessin = MonImage

Remarks

Coordinates of the arc

If the start and end points are not located on the border of the circle (or on the border of the ellipse), the point taken into account corresponds to the intersection between the circle and the line that joins the specified point and the center of the rectangle (which means the center of the circle).
Coordinates of the arc
The origin used to calculate the coordinates corresponds to the upper-left corner of the image (coordinates: (0,0)).

Drawing a solid figure

To draw a solid figure (a full arc), use <picLayer variable>.DrawChord or <picLayer variable>.DrawSlice.
