Some PDFs are converted improperly using imagemagick

Question

I faced with following problem with using ImageMagic. I have Java EE web application which need to make some thumbnails from uploaded PDFs. 3rd party application uploads PDFs to my application.

My application tryes to convert this PDF (and others) via following command

convert some.pdf  -auto-orient -resize 100x100> some.png

As result of convertation I have this PNG. I'm trying for 3 days but wasn't able to figure out whats wrong with uploaded PDFs. Other PDFs is converted in correct way. What's wrong with this PDFs and how to convert it right?

Note: Imagemagick V6.8.6.6, GhostScript 8.64.

Answer 1

Upgrading your version of GhostScript should fix the problem. Ghostscript is responsible for creating an image from your PDF file. With the latest version (9.10) a correct image is created.
