Drawing functions, zoom and automatic scrollbars

The "Automatic scrollbars and zoom" option, available for Image controls, is not compatible with dStartDrawing. If this option is used on the Image control, dStartDrawing freezes the image in the control. The zoom is also fixed. The standard behavior is restored during the call to dEndDrawing.

The same effect can be noticed with dPixelColor and dRotation.
