Issue

Batch Instances failing in folder import module with error message “Exception in breaking the input file. Byte array is not a valid JPEG-file” error in the logs

Solution

This issue was resolved in Ephesoft Transact 4.5.0.0.
We have checked the provided files and after analyzing the same we can see that the file has a compression of JPEG. There is a known issue with ITEXT while converting JPEG and JPEG-2000 compression type. 
Figure 1. Details Page
The workaround is to use a TIF file with a size less than 15MB or to change the compression of these images from where they are getting originated. 

Additional Information

The conversion flow is as below:
  • If the file size of TIFF is greater than 15MB first it is converted to PDF file using ITEXT and then further pdf is processed using GhostScript/Recostar and resulting TIFF file is processed using ImageMagick whereas,
  • If the file size of TIFF less than 15MB it is processed directly using ImageMagick.
  • ITEXT is unable to process TIFF files with a compression type of JPEG/JPEG-2000.
