object of type 'int' has no len()

I got the image from docker but when I try to run the example I get the following error:

root@30d50900394b:/opt/ocr# python /opt/ocr/tesseractserver.py -p 1688 -b /root/local/lib -d /root/local/share/tesseract-ocr

I can take a shot at fixing it if you can provide some hints on where I should begin.

Hi,

Thanks for reporting this!
I checked the code and it seems to have something wrong while processing GIF format, I just add a commit to revise it, and it should work now.

Please check this commit:

Thanks for a quick turn around on this. That seems to fix the error. I'm able to run the service now, however, the results are very gibberish

I'll try to play around with it and send merge request if I'm able to produce better results.

Hi,

That would be appreciated if you can help investigate this, as I remembered, this wired output didn't happen before. Anyway, this issue is closed and please share with me if you have any findings, thanks.
