public int EnumerateSegments(
MrcEnumerateSegmentsInfo callback
)
callback
Callback method that will be called to enumerate the segments.
This method enumerates all the segments using the MrcSegmenter method. This method is valid with all of the segmentation processes. For more information, refer to Programming with LEADTOOLS MRC.
