Unable to convert .tif (multipages .tif file) to pdf using pdfsandwich on Ubuntu

[DEEPAK-KESWANI]

Hi,

I have tried with OCR Action as well as the same command I tried on the Ubuntu terminal but with no luck.

I'm getting below error when I use OCR Action & when I execute below command directly from Terminal on Ubuntu for .tif (Multipages tif file) to .pdf file.

Can you please help on this?

$ /usr/bin/pdfsandwich -verbose -lang spa+eng+fra Sample_3_Multi_page.tif -o Sample_3_Multi_page.pdf

Try using OCRmyPDF instead, it works better with TIFF files.

Hi Angel,

I have installed OCRmyPDF tool and through command line it works perfect but through addon, it throws below error:

What could be the issue?

If you are using Alfresco installer, probably you should create a shell script to isolate environment execution.

Some samples are available at FAQ.
