[DataMemberAttribute("PagesZones")] public OcrPagesZones PagesZones {get; set;}
'Declaration <DataMemberAttribute("PagesZones")> Public Property PagesZones As OcrPagesZones
'Usage Dim instance As DocumentConvertOptions Dim value As OcrPagesZones instance.PagesZones = value value = instance.PagesZones
[DataMemberAttribute("PagesZones")] public: property OcrPagesZones^ PagesZones { OcrPagesZones^ get(); void set ( OcrPagesZones^ value); }
When the value of this property is the default of null (Nothing in Visual Basic), the service will perform auto-zoning on each page in the source document.
If you have pre-defined zones, then create an object of type OcrPagesZones and put it in the PagesZones property. Add the zones to the OcrPageZones.Zones list and set the OcrPageZones.PageNumber value to the page associated with this zone in the source document. The service will load the zones for each page from this list and add them directly to the page before recognition and skips the auto-zoning process.
If the OcrPageZones entry for a specific page is null (Nothing in Visual Basic) or does not contains any OcrZone items, then auto-zoning is performed on this page.
