Description

please download a pdf from http://www.fujixeroxprinters.com.au/downloads/uploaded/DocuPrint%20Mono%20205%20Series_8c68.pdf (now attached to this issue)

and Try converting it to images using below command through command prompt :-
java -jar pdfbox-app-1.6.0.jar PDFToImage abc123.pdf

It generated images for me but images generated are of very poor quality and I can see exceptions also in command prompt.
Below is the error I get on console :-
