No multiple threads can use X11 at the same time, i'm not an expert on the poppler glib bindings but instead poppler_page_render_to_pixbuf that seems to render to an X11 pixmap, you should use the glib function that does not use X11 at all (don't know the name but i'd say it exists as as far as i remember evince is multithreaded) Albert > > and, I use poppler 0.10.0. > > Thank you! > > > -- > ,= ,-_-. =. > ( (_/)o o(\_) ) > `-'(. .)`-' > \_/ > _______________________________________________ > poppler mailing list > [email protected] > http://lists.freedesktop.org/mailman/listinfo/poppler _______________________________________________ poppler mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/poppler
