Remarks
This property is most commonly used with nonintegrated tablet devices—the buffer gives users a margin of error when writing on a device that may not map 1 to 1 with the display screen.
The margin is specified in screen coordinates. A positive margin extends outside the context, a negative margin extends inside the context, and a value of zero produces no margin. Ink is collected if the stroke starts within the margin. This behavior does not clip the ink. The context of the object or control is either the window input rectangle from the GetWindowInputRectangle method or the client rectangle for the window.
The margin is effective only within the application's window. If the pen is applied outside the application's window, then the application loses focus and cannot collect ink.
Note: The InkCollector object, the InkOverlay object, or the InkPicture control must be disabled before setting this property. To disable the InkCollector or InkOverlay object, set the Enabled property to FALSE. To disable inking in the InkOverlay control, set the InkEnabled property to FALSE. You can then set the MarginX property, and re-enable the object or control by setting the Enabled property (or InkEnabled property) to TRUE.
