Hi, I'm comparing the features of xpdf-poppler (the package provided by OpenSuse 12.1, which uses libpoppler 0.18.0) and Adobe Reader 9.5.1 (provided by the same distribution). The most important thing I need to compare is the compatibility of both document readers regarding the PDF document versioning. The Wikipedia page for PDF [1] shows this list with the relations between Acrobat Reader versions and versions of PDF: <ul><li>1993 – PDF 1.0 / Acrobat 1.0</li><li>1994 – PDF 1.1 / Acrobat 2.0</li><li>1996 – PDF 1.2 / Acrobat 3.0</li><li>2000 – PDF 1.3 / Acrobat 4.0</li><li>2001 – PDF 1.4 / Acrobat 5.0</li><li>2003 – PDF 1.5 / Acrobat 6.0</li> <li>2005 – PDF 1.6 / Acrobat 7.0</li><li>2006 – PDF 1.7 / Acrobat 8.0</li><li>2006 – PDF 1.7 / Acrobat 8.2</li><li>2008 – PDF 1.7, Adobe Extension Level 3 / Acrobat 9.0</li><li>2009 – PDF 1.7, Adobe Extension Level 5 / Acrobat 9.1</li> </ul> Is there any way to obtain a similar list for poppler (at least of the latest versions).
