    In This Topic
    Gets or sets a BilevelBitmap that can be used to monitor changes in the target bitmap. Its pixels are used as boolean flags indicating changes in the target. When a pixel in the target bitmap is changed, the corresponding pixel in this bitmap is set to 1 (true). The BilevelBitmap must have the same pixel size as the target bitmap. It is user's responsibility to clear this bitmap (fill it with zeros) before any drawing on the target occurs.
