Versions 24 and later New in version 24 Syntax
Drawing a rectangle by specifying the coordinates of rectangle Hide the details
dRectangle([<Image>, ] <X1> , <Y1> , <X2> , <Y2> [, <Background> [, <Line>]])
<Image>: Optional control name or optional Image, WDPic or picLayer variable Versions 24 and later New in version 24
<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 Background variable. In this case, the gradient defined in the variable is ignored. New in version 21 Background variable. In this case, the gradient defined in the variable is ignored. Background variable. In this case, the gradient defined in the variable is ignored. - characteristics specified in the last call to dBackground if this parameter is not specified.
<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 a Color variable, New in version 22 a Color variable, a Color variable, - identical to the color used for the background if this parameter is not specified and if dPen has not been used.
- Characteristics of the line:
Versions 21 and later 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 dPen 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 dPen 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 dPen is used. If this function has not been used, the line will be solid.
New in version 21 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 dPen 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 dPen 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 dPen is used. If this function has not been used, the line will be solid.

Remarks Coordinates The coordinates are given in relation to the top left corner of the image or Image control ((0, 0) coordinates). Versions 16 and later New in version 16
