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.
