Content transformers choice, fallback or default settings

deajan — Mon, 14 Jan 2013 23:47:29 GMT

Hello,I've setup a test VM of Alfresco 4.2c community edition.I adapted a tiff2pdf content transformer xml file for ABBYY Finereader OCR, which works, but gets somehow overrided by ImageMagick's own tiff2pdf transformer.When i launch Alfresco server, the transformer i made works, checked via the pag

Well i have a 'ugly' solution to disable ImageMagick (or simply reinstall and not choosing ImageMagick) but it works:


# mv /opt/alfresco-4.2.c/common/bin/.convert.bin /opt/alfresco-4.2.c/common/bin/.convert.old
‍‍‍

This completly disables Imagemagick, including the tiff2pdf transformer which alfresco seems to have a preference for.
It works but this is a really ugly solution.

Anyone could help me find something nicer please ?

Thanks.

Hi Deajan

Let me ask you this question please as I am trying to get the same, a tiff to OCR PDF transformation with ABBYY OCR CLI for linux.

We have an Alfresco 4.2.f CE instance and ABBYY OCR4Linux CLI 9 installed in our ubuntu machine. We have checked that ABBYY OCR works fine, but we are not able to run the transformation in Alfresco.

First of all we have included in our web-client-config-custom.xml


 <!– Add the tiff mime type to the list of supported transformations –>

    <config evaluator="string-compare" condition="Action Wizards">

        <transformers>

            <transformer name="image/tiff"/>

        </transformers>

    </config>

‍‍‍‍‍‍‍‍‍‍‍‍‍‍

and declared our transformation in tomcat/shared/classes/alfresco/extension

Also in the http://localhost:8080/alfresco/service/mimetypes?mimetype=image/tiff#image/tiff we obtain the right transformation details


image/tiff - tiff
Extractors: org.alfresco.repo.content.metadata.TikaAutoMetadataExtracter
Transformable To:

    application/eps = Proxy via: com.sun.proxy.$Proxy15(Version: ImageMagick 6.8.6-6 2013-07-24 Q16 http://www.imagemagick.org Copyright: Copyright (C) 1999-2013 ImageMagick Studio LLC Features: DPC Modules Delegates: freetype jng jpeg png ps tiff wmf zlib)
    application/pdf = Proxy via: org.alfresco.repo.content.transform.RuntimeExecutableContentTransformerWorker(ABBYY FineReader Engine 9.0 Sample © ABBYY. 2010.
‍‍‍‍‍‍‍‍

However when we launch this transformation, we are able to get a PDF, but including the TIFF image with no OCR obtained… which makes me think that Alfresco is not calling our transformation to create this PDF.

I have followed also your suggestion to disable ImageMagic…. but if I do so I get this error message

Could you please point me which steps exactly did you follow to get your transofrmation with ABBYY OCR CLI working??

Thanks a lot
