Draws a rounded rectangle:
  • in an Image control,
  • in a variable of type Image.
  • WINDEV in a variable of type WDPic (on the background layer),
  • WINDEV in a variable of type picLayer.
Note: To draw custom rectangles, use the dBorder function..
Linux Caution: In Linux, this function requires a specific configuration. For more details, see Drawing in WINDEV, WEBDEV and WINDEV Mobile.
Example
// Initialise le dessin dans un champ Image
dStartDrawing(IMG_Dessin)

// Dessin d'un rectangle arrondi dont le fond est jaune clair
// et le bord bleu clair
dRoundedRectangle(10, 10, 50, 50, 3, LightYellow, LightBlue)
WINDEVUser code (UMC) 
// Dessin d'un rectangle arrondi dont le fond est jaune clair

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 the dDrawingStartfunction
    • 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.
        If function dEndDrawing is called in the same process as function dStartDrawing, the drawing will not appear: it will be automatically deleted.
  • WindowsLinuxUser code (UMC) Method 2: specify design destination directly in syntax (via parameter)
    The <Image> parameter is used to specify directly the target of the drawing. dStartDrawing becomes useless. This function must be deleted.
