Remarks

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 when dEndDrawing is called.

You can get the same effect with dPixelColor and dRotation.

Limitation

This property applies only to:

Image controls with the "Automatic scrollbars and zoom" option.
Map controls.
