// Initializes the drawing in the Image control
dStartDrawing(IMG_Drawing)

Rect is Rectangle
Rect.X = 10
Rect.Y = 15
Rect.Width = 100
Rect.Height = 150
BorderStyle is Border
BorderStyle.Color = LightBlue
BorderStyle.Round = 30
BorderStyle.Thickness = 1
BackgroundStyle is Background
BackgroundStyle.Color = LightGreen
dBorder(Rect, BorderStyle, BackgroundStyle)

// Draw a rectangle with blue borders, green background and rounded corners

dBorder(IMG_Drawing ,Rect, BorderStyle, BackgroundStyle)

Syntax

dBorder([<Image>, ] <Borders> [, <Border style> [, <Background style>]])

<Image>: Optional control name or optional Image variable

Image to use. The image can correspond to:
the name of an Image control.
the name of a variable of type Image.
This type of variable is not available.
If this parameter is not specified, it is necessary to define the drawing destination with dStartDrawing.
This parameter is not available.

<Borders>: Rectangle variable

Name of the Rectangle variable that specifies the limits of the border to draw.

<Border style>: Optional Border variable

Name of the Borders variable that describes the border style.
If this parameter is not specified or if the Color, Thickness and Line properties of the Borders variable are not defined, the current style information (defined by dPen) is used. If dPen 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.
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.

Drawing in Browser code

Some drawing functions are available in Browser code. The drawing functions in Browser code are based on the HTML 5 standard. More specifically, these functions are based on the "canvas" tag of HTML 5.

The drawing features in browser code are available for the recent browsers only (supporting the HTML 5 standard). To find out whether the drawing features are proposed by your browser, use DrawingAvailable.

Caution: To use the drawing functions with Internet Explorer 9, the project must include the reference to the DTD file. To do so, the HTML mode must be "HTML 4.01 Transitional + DTD". This option is available in the "Advanced" tab of the description window of project.
Reminder: To open the project description window, go to the "Project" tab, "Project" group and click "Description".

Special case: Drawing in the browser of an Android phone: The browser drawing functions are only available starting with version 3 of Android.
