dRoundedRectangle (Function) In french: dRectangleArrondi Draws a rounded rectangle: - in an Image control,
- in a variable of type Image.
Remark: To draw custom rectangles, it is recommended to use dBorder.
// Initialize the drawing in an Image control
dStartDrawing(IMG_Drawing)
// Draw a rounded rectangle whose background is light yellow
// and whose border is light blue
dRoundedRectangle(10, 10, 50, 50, 3, LightYellow, LightBlue)
Syntax
Drawing a rounded rectangle by specifying the coordinates of the rectangle and the diameter of corners Hide the details
dRoundedRectangle([<Image>, ] <X1> , <Y1> , <X2> , <Y2> , <Corner diameter> [, <Background> [, <Line>]])
<Image>: Optional control name or optional Image, WDPic or picLayer variable
<X1>: Integer X-coordinate (in pixels) of the upper-left corner of the rectangle. <Y1>: Integer Y-coordinate (in pixels) of the upper-left corner of the rectangle. <X2>: Integer X-coordinate (in pixels) of the lower-right corner of the rectangle. <Y2>: Integer Y-coordinate (in pixels) of the lower-right corner of the rectangle. <Corner diameter>: Integer Diameter of rectangle corners. <Background>: Integer or Integer constant (optional) - Background color of rectangle. This color can be:
- Background characteristics:
- 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:If this parameter is not specified: - color specified in the last call to dPen.
- color identical to the color used for the background if dPen has not been used.
Drawing a rounded rectangle by specifying the coordinates of the rectangle and the border type Hide the details
dRoundedRectangle([<Image>, ] <X1> , <Y1> , <X2> , <Y2> , <Border> [, <Background>])
<Image>: Optional control name or optional Image, WDPic or picLayer variable
<X1>: Integer X-coordinate (in pixels) of the upper-left corner of the rectangle. <Y1>: Integer Y-coordinate (in pixels) of the upper-left corner of the rectangle. <X2>: Integer X-coordinate (in pixels) of the lower-right corner of the rectangle. <Y2>: Integer Y-coordinate (in pixels) of the lower-right corner of the rectangle. <Border>: Border variable Name of the Border variable that defines the characteristics of the rectangle. Only the following properties are taken into account: - Round: if the property corresponds to the RoundingUndefined constant, no rounding is performed.
- Color: if the property is set to ColorUndefined, the color defined in 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 is set to ThicknessUndefined, the thickness defined in the last call to dPen is used. If this function has not been used, the thickness will be set to 1.
- Line: if the property is set to LineUndefined, the type of line defined in the last call to dPen is used. If this function has not been used, the line will be solid.
<Background>: Integer, constant or Background variable (optional) - Background color of rectangle. This color can be:
- Background characteristics:
- 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.

<Image>: Optional control name or optional Image, WDPic or picLayer variable
<Rectangle>: Rectangle variable Name of the Rectangle variable that defines the coordinates of the rectangle to draw. <Corner diameter>: Integer Diameter of rectangle corners. <Background>: Integer, constant or Background variable (optional) - Background color of rectangle. This color can be:
- Background characteristics:
- 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:If this parameter is not specified: - color specified in the last call to dPen.
- color identical to the color used for the background if dPen has not been used.
Drawing a rounded rectangle via a Rectangle variable and a Border variable Hide the details
dRoundedRectangle([<Image>, ] <Rectangle> , <Border> [, <Background>])
<Image>: Optional control name or optional Image, WDPic or picLayer variable
<Rectangle>: Rectangle variable Name of the Rectangle variable that defines the coordinates of the rectangle to draw. <Border>: Border variable Name of the Border variable that defines the characteristics of the rectangle. Only the following properties are taken into account: - Round: if the property corresponds to the RoundingUndefined constant, no rounding is performed.
- Color: if the property corresponds to the ColorUndefined constant, the color specified 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 specified during the last call to dPen is 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 specified during the last call to dPen is used. If this function has not been used, the line will be solid.
<Background>: Integer, constant or Background variable (optional) - Background color of rectangle. This color can be:
- Background characteristics:
- 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.
Remarks Coordinates Coordinates are specified with respect to the upper-left corner of the image or Image control (coordinates: (0,0)). Using the drawing functions The drawing functions can be used according to 2 methods: - Method 1: Using dStartDrawing
- dStartDrawing must be called before any other drawing function. dStartDrawing is used to define the element (Image control or variable) to which the drawing functions will be applied.
- When drawing on an Image control:
- The drawing functions operate on a copy ("bitmap") of the image. You can use the drawing functions of Windows (via API or CallDLL32) but these functions must use the DC (Device Context) returned by dStartDrawing.
- dEndDrawing and dStartDrawing must not be called in the same process.
The drawing will not be displayed if dEndDrawing and dStartDrawing are called in the same process: it will be automatically erased.
  Method 2: indicating the drawing target directly in the syntax (via a parameter)
The <Image> parameter is used to specify directly the target of the drawing. dStartDrawing becomes useless. This function must be deleted.
