Comments

When adding a zone, the application should directly initialize the following members of ZONEDATA2 structure, since these members do not take default values:

uStructSize   
rcArea   
FillMethod   
CharFilter   
Type   
RecogModule 

The Type member of the ZONEDATA2 structure should be one of the following values:

DOC2_ZONE_FLOWTEXT

DOC2_ZONE_TABLE

DOC2_ZONE_GRAPHIC

The index of the first zone in the zone list is zero (0).

To update only the zone area, call the L_Doc2Zone function.

For OCR zones (zones that detected by calling the L_Doc2FindZones function), the following members cannot be changed:

ZONEDATA2.rcArea, ZONEDATA2.Type, ZONEDATA2.pfnCallback.

But, you can update all ZONEDATA2 members for user zones.
