I've just tested with ghostscript 10.02.1 and found the situation remains as described in 2015, below. Specifically, I checked that: * the four files attached in message #15 all render without issues using evince * tp2A_scilab_N1.pdf renders fine with xpdf, but many warning are emitted on the console S(yntax Warning: Bad bounding box in Type 3 glyph) * ps2pdf 10.02.1 produces a pdf file that again renders fine, but shows the same syntax warnings as noted above * rendering to png (as below) works fine -Steve On Thu, 29 Oct 2015 17:17:50 +0100 (CET) whoami314@free.fr wrote: > Secondly, the pdf viewers available in Jessie are doing a better job > at displaying this test.pdf: > - Evince (or actually the underlying poppler library) is now displaying correctly > this problematic pdf.
