Draws a border:
  • in an Image control,
  • in an Image variable.
Example
// Dessine un rectangle avec bords bleus, fond vert et coins arrondis
// dans un champ Image
 
// Initialise le dessin dans le champ Image
dStartDrawing(IMG_Dessin)

Syntax
dBorder([<Image>, ] <Border> [, <Border style> [, <Background style>]])
<Image>: Optional control name or optional Image variable
Versions 24 and later
Image to use. This image can correspond to:
  • the name of an Image control.
  • on behalf of an Variable of type Image.
If this parameter is not specified, it is necessary to define the drawing destination with dStartDrawing.

Image to use. This image can correspond to:
  • the name of an Image control.
  • on behalf of an Variable of type Image.
If this parameter is not specified, it is necessary to define the drawing destination with dStartDrawing.
<Border>: Rectangle variable
Name of the Rectangle variable that specifies the limits of the border to draw.
<Border style>: Optional Border variable
Name of the Border variable that describes the border style.
If this parameter is not specified or if the Color, Thickness and Feature properties of the Variable of type Border are undefined, the information of the current style (defined by the dPen function) is used. If the dPen function has not been used:
  • Border color: corresponds to the background color of the rectangle.
  • Thickness: 1
  • Line: corresponds to the LineSolid constant.
<Background style>: Optional Background variable
Name of the Background variable that describes the background style.
If this parameter is not specified, the information of the current brush is used.
Remarks

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.
  • Versions 24 and later
    iPhone/iPadUser code (UMC) 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. The dStartDrawing function becomes unnecessary. This function must be deleted.
