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 variable 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 preset color of WLanguage,
Versions 22 and later
a Color variable,
New in version 22
a Color variable,
a Color variable,
transparent if this parameter is not specified and if <Image variable>.Background was not used beforehand.
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 <Image variable>.Background if this parameter is not specified.
To use a gradient background color, call <Image 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 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 <Image variable>.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 ColorUndefined constant, the color defined during the last call to <Image variable>.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 variable>.Pen will be 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 variable>.Pen is used. If this function was not used, the line is a solid line.
