Overview |
Refer to Creating and Using a Bitmap Region. |
Remarks
Enables automatic creation of a bitmap region, based on MouseDown, MouseMove, and MouseUp events.
This method supports creation of a rectangle, rounded rectangle, ellipse, or freehand region. It automatically handles scaling differences between the displayed image and the bitmap. On the MouseDown event, it begins outlining where the region will appear on the screen. It updates the outline on each MouseMove event. Then, on the MouseUp event, it deletes the displayed outline and creates the bitmap region. To make an outline of the region visible at that point, you must set the RgnFrameType property.
