I think that the problem is in evince. It sets wrong angle for rendering with spectre_render_context_set_rotation() from my point of view. evince rotates to left by setting new angle to "original_angle - 90". If you reverse the value passed by evince to libspectre (360 - angle) then it works as expected. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to evince in Ubuntu. https://bugs.launchpad.net/bugs/1242678 Title: evince cannot render some EPS files Status in Evince document viewer: New Status in GS-GPL - GPL Ghostscript: Unknown Status in libspectre: Confirmed Status in “evince” package in Ubuntu: Confirmed Status in “ghostscript” package in Ubuntu: Invalid Status in “gnuplot” package in Ubuntu: Invalid Status in “libspectre” package in Ubuntu: Triaged Status in “evince” source package in Trusty: Confirmed Status in “ghostscript” source package in Trusty: Invalid Status in “gnuplot” source package in Trusty: Invalid Status in “libspectre” source package in Trusty: Triaged Bug description: I upgraded to Ubuntu Saucy, evince cannot render EPS files generated by gnuplot. (Just show an empty page.) [how to reproduce] 1. Generate an EPS file using gnuplot by executing the following command. $ gnuplot -e "set terminal postscript; set output 'test.eps'; plot x;" 2. Open the file "test.eps" just created. $ evince "test.eps" The following are what evince writes to the terminal. (evince:24176): EvinceDocument-CRITICAL **: ev_document_get_n_pages: assertion 'EV_IS_DOCUMENT (document)' failed (evince:24176): Gtk-WARNING **: drawing failure for widget `EvView': invalid matrix (not invertible) (evince:24176): Gdk-CRITICAL **: gdk_pixbuf_get_from_surface: assertion 'width > 0 && height > 0' failed (evince:24176): Gdk-CRITICAL **: gdk_pixbuf_get_from_surface: assertion 'width > 0 && height > 0' failed 3. Then evince just shows an empty (white) page. === If i rotate 90 or -90 degree by pressing Ctrl+Left or Ctrl+Right key, evince can show this file correctly. === Okular, GIMP, inkscape and gs can show this EPS file.
