Draw a rectangle in an Variable of type WDPic (on the background layer).
Example
MonImageWDPic est un WDPic = "Test.gif"
 
// Dessin d'un rectangle dont le fond est jaune clair
// et le bord bleu clair
MonImageWDPic.DessineRectangle(10, 10, 50, 50, JauneClair, BleuClair)
 
IMG_MonDessin = MonImageWDPic
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 variable of type WDPic to be used. 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 Variable de type Background. In this case, the gradient defined in the variable is ignored.
      New in version 21
      WINDEV Variable de type Background. In this case, the gradient defined in the variable is ignored.
      WINDEV Variable de type Background. 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:
    • an RGB color (returned by RGB),
    • an HSL color (returned by HSL),
    • a WLanguage preset color,
    • Versions 22 and later
      WINDEV a variable of type Color,
      New in version 22
      WINDEV a variable of type Color,
      WINDEV a variable of type Color,
    • same as Color used for Background if this parameter is not specified and if <WDPic variable>.Pen was not used.
  • 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 constant ColorUndefined, the Color defined during the last call to the function <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 constant ThicknessUndefined, the thickness defined during the last call to the function <WDPic variable>.Pen is used. If this function has not been used, the thickness will be set to 1.
      • Line: if the property is LineUndefined, the type of Line defined during the last call to the <WDPic variable>.Pen function is used. If this function has not been used, the line will be solid.
        New in version 21
        WINDEV Border variable. In this case, only the following properties are taken into account:
        • Color: if the property corresponds to the constant ColorUndefined, the Color defined during the last call to the function <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 constant ThicknessUndefined, the thickness defined during the last call to the function <WDPic variable>.Pen is used. If this function has not been used, the thickness will be set to 1.
        • Line: if the property is LineUndefined, the type of Line defined during the last call to the <WDPic variable>.Pen function is used. If this function has not been used, the line will be solid.
