Thanks again Nicolas. I don't have answer nor fixes for all the issues you mention. But in any case the goal is rather to get a fair idea of the troubles we can face with the different pdf embedding solutions. And you are providing very useful efforts towards this purpose.  <div>
<br></div><div>I would add one moderation to that assessment: unless I'm mistaken, some pdf that you tested are not representative of what we expect in IPOL. Beyond that, it would more relevant to test pdf for which we know how they were generated. In fact, it's only useful to test pdfs that are generated with latex, and in particular with the IPOL latex template we are creating. <div>
<br></div><div>Meanwhile, here are few of my guesses or fixes about the issues you reported:</div><div><br></div><div>"""</div><div><meta http-equiv="content-type" content="text/html; charset=utf-8"><a href="http://dev.ipol.im/~simonl/php/pdfInHtml/pdfjs/viewer.html?file=../upload/2010_Van_Gorp_Grefen_-_Supporting_the_internet-based_evaluation_of_research_software_with_cloud_infrastructure.pdf" target="_blank">http://dev.ipol.im/~simonl/php/pdfInHtml/pdfjs/viewer.html?file=../upload/2010_Van_Gorp_Grefen_-_Supporting_the_internet-based_evaluation_of_research_software_with_cloud_infrastructure.pdf</a><br>
