Syntax
dDisplay()
Remarks

Operating mode

In browser code, transferring the drawing into the image can be quite long (several drawing functions will be used).
To optimize the drawing in the image, the drawing can be displayed once the drawing functions have been used. To do so, you must:
  1. Start drawing with dStartDrawing by using the dForceDisplay constant.
  2. Use the drawing functions to create the drawing.
  3. Use dDisplay to display the drawing in the image.
