Comments
When adding a zone, the application should directly initialize the following members of ZONEDATA structure, since these members will not take their default values:
uStructSize
rcArea
FillMethod
CharFilter
Type
RecogModule
The application should not modify the ID zone member, except for OMR zones using the "filled-in-error" facility.
The Type member of the ZONEDATA structure should be one of the following values:
ZONE_FLOWTEXT
ZONE_TABLE
ZONE_GRAPHIC
The index of the first zone in the zone list is zero (0).
To update only the zone area, call L_DocZone.
