Subject: Re: extracting images from pdf problem
Date: Sun, 05 Apr 2009 09:06:32 +0200Hi,
There is a lot of difference in how different pdf writers save their files, and sometimes this causes trouble when trying to extract data from them. I could tell you more if you send me the pdf or a link to it so I can see myself what is happening.
