Remarks
(Document/Medical)This event is triggered for each line found by the LineRemove method. Set the DocCleanSuccess property to SUCCESS_REMOVE to have the line removed. Set the DocCleanSuccess property to SUCCESS_NOREMOVE to leave the line unchanged. Set the DocCleanSuccess property to 0 to abort. If the uFlags parameter of the LineRemove method is set to LINE_IMAGE_UNCHANGED | LINE_SINGLE_REGION, then the value of the DocCleanSuccess property affects only the internal single region that contains all changes.
|
Note: |
hRgnLine is only valid during this event. To use the hRgnLine after the event has terminated, make a copy of it using the SetRgnHandle method. |
