Dynamically Suppress Orientation Detection for Full Page OCR

Question / Problem:

Dynamically Suppress Orientation Detection for Full Page OCR

Answer / Solution:

The Automatic Rotation option for Full Page OCR applies to the entire project. It is not possible to switch off orientation for single classes.

The following script shows a workaround, which allows you to switch off orientation detection for OCR. The use of the script requires that you can classify the document without OCR, e.g. layout classifier.

Private Sub Document_AfterClassifyXDoc(pXDoc As CASCADELib.CscXDocument)
Dim i As Long
If pXDoc.ExtractionClass = "MyClass" Then
change orientation for all pages from unknown to NoRotation
this will prevent the OCR from doing orientation detection
For i = 0 To pXDoc.CDoc.Pages.Count - 1
pXDoc.CDoc.Pages(i).Rotation = Csc_RT_NoRotation
Next i
End If
End Sub
