Syntax

Draw a circle, specifying all the coordinates of the rectangle containing the circle. Hide the details

<WDPic image>.DrawCircle(<X1> , <Y1> , <X2> , <Y2> [, <Background color> [, <Line color>]])
<WDPic image>: WDPic variable
Name of the WDPic variable to be used. Only the background layer will be handled.
<X1>: Integer
X-coordinate of the upper-left corner of the rectangle containing the circle. These coordinates are expressed in pixels.
<Y1>: Integer
Y-coordinate of the upper-left corner of the rectangle containing the circle. These coordinates are expressed in pixels.
<X2>: Integer
X-coordinate of the lower-right corner of the rectangle containing the circle. These coordinates are expressed in pixels.
<Y2>: Integer
Y-coordinate of the lower-right corner of the rectangle containing the circle. These coordinates are expressed in pixels.
<Background color>: Integer or constant (optional)
Circle background color. This color can correspond to:If this parameter is not specified, the background color:
<Line color>: Integer or constant (optional)
Color of the circle line. This color can correspond to:If this parameter is specified, the characteristics defined with <WDPic variable>.Pen are ignored. The line thickness will be set to 1.
If this parameter is not specified, the line color:
  • is Transparent if the function <WDPic variable>.Pen has not been used before.
    New in version 2024
    In the case of an Variable type Image, the row will have the black Color..
  • corresponds to the color specified in the last call to <WDPic variable>.Pen.
