Problem during ocr #25

Closed tap90 closed 7 years ago

tap90 commented 7 years ago

When I put some pdf files in the alfresco folder configured with the rule (ocr-extraction) Alfresco creates a new version of the file without perform ocr correctly.

When this happens It writes this in the alfresco.log: `Version: ImageMagick 6.9.1-10 Q16 x86_64 2015-08-12 http://www.imagemagick.org Copyright: Copyright (C) 1999-2015 ImageMagick Studio LLC License: http://www.imagemagick.org/script/license.php Features: Cipher DPC Modules Delegates (built-in): freetype jng jpeg ltdl png tiff wmf

I have noticed this error:

Can it generate this problem? How can I fix this?

Thanks in advance

Maybe you can try the instruction by command line to debut the problem, as input file is still stored on your filesystem.

tap90 commented 7 years ago

Sorry for the ignorance Which command should I try?

angelborroy-ks commented 7 years ago

pdfsandwich /opt/alfresco-community/tomcat/temp/Alfresco/OCRTransformWorker_source_6425226260248108572.pdf -o /opt/alfresco-community/tomcat/temp/Alfresco/OCRTransformWorker_source_6425226260248108572_ocr.pdf -verbose -lang spa+eng+fra

This is the output:

I think the problem start with this line when pdfsandwich try to use gs -v command gs: symbol lookup error: /lib64/libgs.so.9: undefined symbol: cmsCreateContext

I have try to use this command and the output is the same

angelborroy-ks commented 7 years ago

Ok, so you have to fix your local gs (GhostScript) installation before trying to run this Alfresco addon.

tap90 commented 7 years ago

Yes, the problem is that ghostscript is installed as dependency of ImageMagick so I don't understand because it doesn't work

angelborroy-ks commented 7 years ago

Different problems can be the cause, however, by executing gs -v you'd receive exactly the same error.

Maybe isolating the problem will help to solve it.

tap90 commented 7 years ago

I have try to remove and install ghostscript now the command gs -v work correctly but when I execute pdfsandwich a new error is generated by ghostscript

Now I'm trying to install the latest version of pdfsandwich I let you know

tap90 commented 7 years ago

With pdfsandwich works correctly It use pdfunite so you need to install this new dependency but It works
