Example
MyWDPic is WDPic = "Test.gif"
// Draw a light yellow arc of circle in MyWDPic variable

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 use. Only the background layer will be handled.
<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 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).
The origin used to calculate the coordinates corresponds to the top 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 <Variable WDPic>.DessinePortion.
