Description
Indicates the number of times the canvas has been locked to prevent interference caused by other threads.
Read LockCount to determine whether the canvas is locked. Whenever the Lock method is called to block other threads from interfering with the canvas, LockCount increases. Whenever the Unlock method is called at the end of a critical section, LockCount decreases. When LockCount is 0, other threads may draw on the canvas.
