By default these zone images are not available from script to optimize memory consumption during document processing. If you activate the property SaveXDocImages of the Advanced Zone Locator in the BeforeExtract event you can access the registered coordinates, the original coordinates, and the preprocessed image for each defined zone. This information is only accessible after extraction and is not saved to disk, you can access this information as shown in the AfterExtract event. You have to add an additional reference, by selecting References from the Edit menu, for the Advanced Zone Locator (Kofax Cascade Advanced Zone Locator 4.0) to the script sheet where you insert the following script code.

' Class Script
Private Sub Document_BeforeExtract(pXDoc As CASCADELib.CscXDocument)

   Dim oClass As CscClass 
   Dim oLocDef As CscLocatorDef 
   Dim oAdvZoneLoc As CscAdvZoneLocator 

   Set oClass = Project.ClassByName("MyClassName") 
   Set oLocDef = oClass.Locators.ItemByName("MyAdvancedZoneLocator") 
   Set oAdvZoneLoc = oLocDef.LocatorMethod 
   oAdvZoneLoc.SaveXDocImages = True 

End Sub 

Private Sub Document_AfterExtract(pXDoc As CASCADELib.CscXDocument) 

   Dim oRep As CscXDocRepresentation 
   Dim oXDocImg As CscXDocImage 
   Dim oImg As CscImage 

   Set oRep = pXDoc.Representations.ItemByName("AdvZoneLoc")    ' this is the image of the 0. defined (first) zone in the advanced zone locator
   Set oXDocImg = oRep.Images(0)  
   Set oImg = oXDocImg.Image 

   oImg.Save("C:\xyz.tif") 

End Sub
