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>: entier X coordinate (in pixels) of top left corner of rectangle. <Y1>: entier Y coordinate (in pixels) of top left corner of rectangle. <X2>: entier X coordinate (in pixels) of bottom right corner of rectangle. <Y2>: entier 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:
- an RGB color (returned by RGB),
- an HSL color (returned by HSL),
- a preset color of WLanguage,
Versions 22 and later      a Variable of type Color , New in version 22      a Variable of type Color ,       a Variable of type Color , - transparent if this parameter is not specified and if the dBackground function has not been used before.
- Characteristics of background:
Versions 21 and later      Variable type Background. In this case, the gradient defined in the variable is ignored. New in version 21      Variable type Background. In this case, the gradient defined in the variable is ignored.       Variable type Background. 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 Variable of type Color , New in version 22      a Variable of type Color ,       a Variable of type Color , - same as Color used for Background if this parameter is not specified and if dPen was not used.
- Characteristics of the line:
Versions 21 and later     Variable type Border. 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 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 constant ThicknessUndefined, the thickness defined during the last call to the function dPen 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 dPen function is used. If this function has not been used, the line will be solid.
New in version 21     Variable type Border. 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 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 constant ThicknessUndefined, the thickness defined during the last call to the function dPen 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 dPen function is used. If this function has not been used, the line will be solid.
     Variable type Border. 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 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 constant ThicknessUndefined, the thickness defined during the last call to the function dPen 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 dPen function is used. If this function has not been used, the line will be solid.
- characteristics specified in the last call to dPen if this parameter is not specified.
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
