Draws a rectangle in a variable of type WDPic (on the background layer).
Example
MyWDPicImage is WDPic = "Test.gif"
 
// Draw a rectangle whose background is light yellow
// and whose border is light blue
MyWDPicImage.DrawRectangle(10, 10, 50, 50, LightYellow, LightBlue)
 
IMG_MyDrawing = MyWDPicImage
Syntax

Drawing a rectangle by specifying the coordinates of rectangle Hide the details

<WDPic image>.DrawRectangle(<X1> , <Y1> , <X2> , <Y2> [, <Background> [, <Line>]])
<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.
<Y1>: Integer
Y-coordinate (in pixels) of the upper-left corner of the rectangle.
<X2>: Integer
X-coordinate (in pixels) of the lower-right corner of the rectangle.
<Y2>: Integer
Y-coordinate (in pixels) of the lower-right corner of the rectangle.
<Background>: Integer, constant or Background variable (optional)
To use a gradient background color, call <WDPic variable>.DrawRectangleGradient.
<Line>: Integer, constant or Border variable (optional)
  • Color of rectangle line. This color can be:
  • Characteristics of the line:
    • WINDEVWEBDEV - Server code Border variable. In this case, only the following properties are taken into account:
      • Color: if the property is set to ColorUndefined, the color defined in the last call to <WDPic variable>.Pen is used. If this function has not been used, the background color of the rectangle will be used.
      • Thickness: if the property is set to ThicknessUndefined, the thickness defined in the last call to <WDPic variable>.Pen is used. If this function has not been used, the thickness will be set to 1.
      • Line: if the property is set to LineUndefined, the type of line defined in the last call to <WDPic variable>.Pen is used. If this function has not been used, the line will be solid.
      • characteristics specified in the last call to <WDPic variable>.Pen if this parameter is not specified.

    <WDPic image>.DrawRectangle(<Rectangle> [, <Background> [, <Line>]])
    <WDPic image>: WDPic variable
    Name of the WDPic variable to be used. Only the background layer will be handled.
    <Rectangle>: Rectangle variable
    Name of the Rectangle variable that defines the coordinates of the rectangle to draw.
    <Background>: Integer, constant or Background variable (optional)
    To use a gradient background color, call <WDPic variable>.DrawRectangleGradient.
    <Line>: Integer, constant or Border variable (optional)
    • Color of rectangle line. This color can be:

        • Line: if the property is set to LineUndefined, the type of line defined in the last call to <WDPic variable>.Pen is used. If this function has not been used, the line will be solid.
      • characteristics specified in the last call to <WDPic variable>.Pen if this parameter is not specified.
    Remarks

    Coordinates

    Coordinates are specified with respect to the upper-left corner of the image (coordinates: (0.0)).
