Ephesoft错误，学习从PDF转换的TIFF文档

Question

I am using the Ephesoft Community edition on a windows server 2003 on AWS instance. I am having issues with ephesoft reading certain tiff documents. I have about 100 different tiff documents and about 70% of them work. These tiff documents were originally PDF's that we have converted using the lastest version of ghostscript and cleaned up using imagemagick from ephesoft. We are using the following commands with ghostscript

-dNOPAUSE -r300 -sDEVICE=tiffg4 -dBATCH

with imagemagick we are doing the following command

-compress group4

When learning one of the tiff files that isn't working we are getting the following error in the log files

Drop Box Link to Stack Trace

And this is one of the Tiff document we are trying to have ephesoft learn

Drop Box Link to Tiff Document

Is there something that I can do with ghostscript, imagemagick or any other software to fix this; or do I need to modify ephesoft in some way?

Answer 1

I found the solution by doing some more research.

The problem didn't involve Ghostscript or Imagmagick. It involved Tesseract and creating the HOCR file. When Tesseract is creating the hocr file it is resolving the value of Texas as Te>. The community edition of Ephesoft cannot handle the special xml character like that and would throw the error as a result.

The solution was to set a Tesseract property of blacklisting the <> symbols so that Tesseract would not include those or resolve to those. My PDF's seem to be working correctly now and I am able to process them.
