dRoundedRectangle (Function)

In french: dRectangleArrondi

Draws a rounded rectangle:

in an Image control,
in an Image variable.
This type of variable is not available.

Caution: A specific configuration is required to use this function in Linux. See The drawings for more details.

Example

// 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)

Versions 24 and later

// Draw a rounded rectangle whose background is light yellow
// and whose border is light blue
dRoundedRectangle(IMG_Drawing, 10, 10, 50, 50, 3, LightYellow, LightBlue)

New in version 24

// Draw a rounded rectangle whose background is light yellow
// and whose border is light blue
dRoundedRectangle(IMG_Drawing, 10, 10, 50, 50, 3, LightYellow, LightBlue)

Remarks

Coordinates

The coordinates are specified in relation to the top left corner of Image control (coordinates set to (0,0)).

Using the drawing functions

The drawing functions can be used according to 2 methods:

Method 1: Using dDrawing
- dStartDrawing must be called before any other drawing function. dStartDrawing is used to define the element (Image control or Image variable) onto 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
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.
New in version 24
