When I use PumaPage, sometimes error:
The liberary dipapi.dll could not be found.
Recognition engine halted with code: 7012364 or 7733267

I don't konw the reason.

Dim OCRResults As String
OCRResults = ""
For i As Integer = 0 To fileList.Items.Count - 1
Dim OCRPage As PumaPage
OCRPage = New PumaPage()
OCRPage.LoadImage(CStr(fileList.Items(i)))
OCRPage.AutoRotateImage = True
OCRPage.FileFormat = PumaFileFormat.TxtAnsi
OCRPage.EnableSpeller = False
OCRPage.Language = PumaLanguage.English
OCRResults = OCRPage.RecognizeToString()
Log.Info("File Name:" & ".... " & CStr(fileList.Items(i)))
OCRPage.Dispose()
Next
