nZoneIndex	Specifies the index of the zone to be updated. This is a zero-based index.
pZoneData	Pointer to the ZONEDATA structure that contains information used to update the zone.

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.
