OCR mail attachment

In your opinion, what's the best/cleanest way to OCR mail-attachments (TIF files from MFC device) that are imported through an external mail source. So, just an e-mail with a tif-file that need to be indexed.

While the External File Import source has the option to OCR the files that are being imported, the mail connector does not have such thing.

We can use a workflow action to OCR, but this seems to have an unpredictable result where OCR isn't performed as it should, it only creates a PDF, but not a searchable one.

I want to prevent that we have to create a solution where mail source imports have to be downloaded/extreacted by an event handler to a file system folder to be imported again in a regular external file import job, it's a bit cumbersome.

    Hi Joonas,

    1:

    Basically the OCR is working, however sometimes I get eventlog errors regarding a timeout in the OCR Action Script when OCR'ing somewhat larger tif files (4MB+).

    Vault.ObjectFileOperations.PerformOCROperation ObjVer, file.FileVer, opts, MFOCRZoneRecognitionModeNoZoneRecognition, Nothing, True


    Is there some tuning possible, because these aren't excessive file sizes.

    2:

    the script sometimes crashes on PDF files that have a digital origin, like a tekst document that was printed to PDF format.

    How would one check if a pdf file is image only, image+text (already OCR'ed), or only digital text ?
