Draws a rectangle in an Image control.
Example
// Draw a rectangle whose background is light yellow
// and whose border is light blue
IMG_Drawing.DrawRectangle(10, 10, 50, 50, LightYellow, LightBlue)
Syntax

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

<Image control>.DrawRectangle(<X1> , <Y1> , <X2> , <Y2> [, <Background> [, <Line>]])
<Image control>: Control name
Name of Image control to use.
<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
      WINDEVUniversal Windows 10 App Background variable. In this case, the gradient defined in the variable is ignored.
      New in version 21
      WINDEVUniversal Windows 10 App Background variable. In this case, the gradient defined in the variable is ignored.
      WINDEVUniversal Windows 10 App Background variable. In this case, the gradient defined in the variable is ignored.
    • characteristics specified in the last call to <Image>.Background if this parameter is not specified.
To use a gradient background color, call dRectangleDegrade_objet.
<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 preset color of WLanguage,
    • Versions 22 and later
      WINDEVUniversal Windows 10 App a Color variable,

    • identical to the color used for the background if this parameter is not specified and if <Image>.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 ColorUndefined constant, the color defined during the last call to <Image>.Pen is used. If this function was not used, the background color of the rectangle is used.
      • Thickness: if the property corresponds to the ThicknessUndefined constant, the thickness defined during the last call to <Image>.Pen is used. If this function was not used, the thickness is set to 1.
      • Line: if the property corresponds to the LineUndefined constant, the type of line defined during the last call to <Image>.Pen will be used. If this function was not used, the line is a solid line.
