My texlive seem to produce a PostScript file that displays okay, but somehow the convert step sets the canvas size to 1020x1320 Adding a -trim parameter to will work around the problem, such as: convert -trim -density 120 a.ps a.png I'll look for a mention of this behavior for Imagemagick shortly (need food) (Sorry for messing up the thread, I guess..) ----- For reference: The files I produced: http://www.mediafire.com/file/6qv8tty0pn1nyz0/formula_test2.tar.bz debug output of convert-step: http://pastebin.com/FdJPEYwr convert -version Version: ImageMagick 6.7.5-6 2012-03-06 Q16 http://www.imagemagick.org Copyright: Copyright (C) 1999-2012 ImageMagick Studio LLC Features: OpenMP latex --version pdfTeX using libpoppler 3.141592-1.40.3-2.2 (Web2C 7.5.6) kpathsea version 3.5.6 Compiled with libpng 1.5.8; using libpng 1.5.10 Compiled with zlib 1.2.5; using zlib 1.2.5 Compiled with libpoppler dvips --version dvips(k) 5.96.1 kpathsea version 3.5.6 ----- _______________________________________________ users mailing list email@example.com http://lists.xwiki.org/mailman/listinfo/users
