Draws a rectangle in a WDPic variable (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 use. Only the background layer will be handled.
<X1>: Integer
X coordinate (in pixels) of top left corner of rectangle.
<Y1>: Integer
Y coordinate (in pixels) of top left corner of rectangle.
<X2>: Integer
X coordinate (in pixels) of bottom right corner of rectangle.
<Y2>: Integer
Y coordinate (in pixels) of bottom right corner of rectangle.
<Background>: Integer, constant or Background variable (optional)
  • Background color of rectangle. This color can be:
  • Characteristics of background:
    • Versions 21 and later
      WINDEV Background variable. In this case, the gradient defined in the variable is ignored.
      New in version 21
      WINDEV Background variable. In this case, the gradient defined in the variable is ignored.
      WINDEV Background variable. In this case, the gradient defined in the variable is ignored.
    • characteristics specified in the last call to <WDPic variable>.Background if this parameter is not specified.
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:
    • Versions 21 and later
      WINDEV Border variable. In this case, only the following properties are taken into account:
      • Color: if the property corresponds to the ColorUndefined constant, the color defined during 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 corresponds to the ThicknessUndefined constant, the thickness defined during the last call to <WDPic variable>.Pen will be used. If this function has not been used, the thickness will be set to 1.
      • Line: if the property corresponds to the LineUndefined constant, the type of line defined during the last call to <WDPic variable>.Pen is used. If this function has not been used, the line will be solid.

<Rectangle>: Rectangle variable
Name of the Rectangle variable that defines the coordinates of the rectangle to draw.
<Background>: Integer, constant or Background variable (optional)

<Line>: Integer, constant or Border variable (optional)
  • Color of rectangle line. This color can be:

    • characteristics specified in the last call to <WDPic variable>.Pen if this parameter is not specified.
Remarks

Coordinates

Coordinates are given with respect to the top left corner of the image (coordinates: (0.0)).
