<WDPic variable>.DrawRectangle (Function)

In french: <Variable WDPic>.DessineRectangle

Draws a rectangle in a WDPic variable (on the background layer).

Versions 15 and later

This function is now available for WEBDEV sites in Linux.

New in version 15

This function is now available for WEBDEV sites in Linux.

Example

MyWDPicImage is WDPic = "Test.gif"

// Draw a rectangle whose background is light yellow
// and whose border is light blue
MyWDPicImage.DrawRectangle(10, 10, 50, 50, LightYellow, LightBlue)

IMG_MyDrawing = MyWDPicImage

Syntax

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

<WDPic image>.DrawRectangle(<X1> , <Y1> , <X2> , <Y2> [, <Background> [, <Line>]])

<WDPic image>: WDPic variable

Name of the WDPic variable to use. Only the background layer will be handled.

<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 <WDPic variable>.Background has not been 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 <WDPic variable>.Background if this parameter is not specified.
To use a gradient background color, call <WDPic 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 <WDPic variable>.Pen 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 <WDPic variable>.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 ThicknessUndefined constant, the thickness defined during the last call to <WDPic variable>.Pen 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 <WDPic variable>.Pen is used. If this function has not been used, the line will be solid.
