Draws a circle arc on an ellipse arc in an Image variable.
The arc is drawn anticlockwise.
Example
MyImage is Image = "Test.gif"
// Draw an arc of circle in light yellow
MyDrawing.DrawArc(10, 10, 50, 50, 20, 20, 40, 50, LightYellow)
 
IMG_MyDrawing = MyImage
Syntax
<Image variable>.DrawArc(<X1> , <Y1> , <X2> , <Y2> , <X3> , <Y3> , <X4> , <Y4> [, <Line color> [, <Line thickness>]])
<Image variable>: Image variable
Name of Image variable to use.
<X1>: Integer
X coordinate (in pixels) of top left corner of the rectangle containing the circle.
<Y1>: Integer
Y coordinate (in pixels) of top left corner of the rectangle containing the circle.
<X2>: Integer
X coordinate (in pixels) of bottom right corner of the rectangle containing the circle.
<Y2>: Integer
Y coordinate (in pixels) of bottom right corner of the rectangle containing the circle.
<X3>: Integer
X coordinate (in pixels) of start point of the arc of circle.
<Y3>: Integer
Y coordinate (in pixels) of start point of the arc of circle.
<X4>: Integer
X coordinate (in pixels) of end point of the arc of circle.
<Y4>: Integer
Y coordinate (in pixels) of end point of the arc of circle.
<Line color>: Integer or constant (optional)
Color of the arc of circle. This color corresponds to:If this parameter is not specified, the line color:
<Line thickness>: Optional integer

Remarks

Coordinates of the arc

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

Drawing a solid figure

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