Syntax

Drawing an arc Hide the details

<WDPic image>.DrawArc(<X1> , <Y1> , <X2> , <Y2> , <X3> , <Y3> , <X4> , <Y4> [, <Line color> [, <Line thickness>]])
<WDPic image>: WDPic variable
Name of the WDPic variable to be used. Only the background layer will be handled.
<X1>: Integer
X-coordinate (in pixels) of the upper-left corner of the rectangle containing the circle.
<Y1>: Integer
Y-coordinate (in pixels) of the upper-left corner of the rectangle containing the circle.
<X2>: Integer
X-coordinate (in pixels) of the lower-right corner of the rectangle containing the circle.
<Y2>: Integer
Y-coordinate (in pixels) of the lower-right corner of the rectangle containing the circle.
<X3>: Integer
X-coordinate (in pixels) of the starting point of the arc.
<Y3>: Integer
Y-coordinate (in pixels) of the starting point of the arc.
<X4>: Integer
X-coordinate (in pixels) of the end point of the arc.
<Y4>: Integer
Y-coordinate (in pixels) of the end point of the arc.
<Line color>: Integer or constant (optional)
Color of the arc of circle. This color can correspond to:If this parameter is not specified, the line color:
<Line thickness>: Optional integer
WINDEVWEBDEV - Server code Thickness (in pixels) of the arc of circle to draw. If this parameter is not specified, the value taken into account can be:
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 <WDPic variable>.DrawChord or <WDPic variable>.DrawSlice.
