Hi, Rendering of file http://home.zcu.cz/~jklement/spolehlivost.pdf is very slow using poppler with splash backend. (current version from CVS). It takes about 6 seconds to render one page. I've profiled poppler using valgrind and kcallgrind to find out what takes so long. You can get profile file here: http://home.zcu.cz/~jklement/callgrind.out.3146.tar.bz2.
It seems that poppler first convert Type3 fonts to bitmaps and then print them to the screen. But bounding box for fonts in this file is 1000x1000 which makes drawing font bitmaps very slow. KCallGrind shows that poppler spends 95% of time in Splash::fillGlyph2. Why don't poppler prints Type3 fonts directly? Another suspicious thing is number of calls of SplashClip::test. Only partialy clipped characters should call SplashClip::test, but it seem that they're incorrectly detected. I think rect of glyph in glyph space is compared with SplashClip in world space. Poppler spends 25% of time in method SplashClip::test. -- Jiri Klement _______________________________________________ poppler mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/poppler
