SMOOTH_SINGLE_REGION:

For each bump or nick found by the Smooth method, if the DocCleanSuccess property is set to SUCCESS_REMOVE in the Smooth event, the removed bump or nick is added to an internal single region. If the DocCleanSuccess property is set to SUCCESS_NOREMOVE, the bump or nick is not added to the single region. When the Smooth method returns, either the DocCleanBitmap property or the hDocCleanRgn property will reference a region that contains all the removed bumps or nicks. If SMOOTH_LEAD_REGION is also set, the DocCleanBitmap will be updated with a bitmap that has a LEAD region that contains all the removed bumps or nicks. If SMOOTH_LEAD_REGION is not set, the hDocCleanRgn property is set to a Windows region that contains all the removed nicks or bumps. When the region (either LEAD or Windows) is no longer needed, it must be destroyed.

SMOOTH_LEAD_REGION

When the Smooth method returns, the DocCleanBitmap property is updated with a copy of the bitmap that also contains a region with all the removed bumps or nicks. This flag must be used in conjunction with SMOOTH_SINGLE_REGION. To use this flag set uFlags to SMOOTH_SINGLE_REGION | SMOOTH_LEAD_REGION. The DocCleanBitmap property will be updated when the Smooth method returns.
