Syntax
Drawing a rectangle by specifying the coordinates of rectangle Hide the details
<Image variable>.DrawRectangle(<X1> , <Y1> , <X2> , <Y2> [, <Background> [, <Line>]])
<Image variable>: Image variable Name of the 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:
- an RGB color (returned by RGB),
- an HSL color (returned by HSL),
- a WLanguage preset color,
 Versions 22 and later      a variable of type Color,  New in version 22 a variable of type Color, - transparent if this parameter is not specified and if the <Image>.Background function has not been used before..
- Characteristics of background:
Versions 21 and later Variable de type Background. In this case, the gradient defined in the variable is ignored.  Variables of type Background are not available in this syntax. Use the <Image>.DrawBorder function to customize the Color of Background. New in version 21 Variable de type Background. In this case, the gradient defined in the variable is ignored. Variables of type Background are not available in this syntax. Use the <Image>.DrawBorder function to customize the Color of Background. Variable de type Background. In this case, the gradient defined in the variable is ignored.
Variables of type Background are not available in this syntax. Use the <Image>.DrawBorder function to customize the Color of Background. - characteristics specified in the last call to <Image>.Background 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 WLanguage preset color,
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 <Image>.Pen was not 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 constant ColorUndefined, the Color defined during the last call to the function <Image>.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 <Image>.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 <Image>.Pen function is used. If this function has not been used, the line will be solid.
- Variables of type Border are not available in this syntax. Use the function <Image>.DrawBorder to customize the Border .
