Remarks
(Document/Medical)This event is triggered once for each area of inverted text that is detected. Set the DocCleanSuccess property to SUCCESS_REMOVE to have the area inverted. Set the DocCleanSuccess property to SUCCESS_NOREMOVE to leave the area unchanged. Set the DocCleanSuccess property to 0 to abort. If the uFlags parameter of the InvertedText methodis set to INVERTEDTEXT_IMAGE_UNCHANGED | INVERTEDTEXT _SINGLE_REGION, then the value of the DocCleanSuccess property affects only the internal single region that contains all the changes.
|
Note: |
hTextRgn is only valid during this event. To use the hTextRgn after the event has terminated, make a copy of it using the SetRgnHandle method. |
