*** Please type your report below this line *** I am not sure this is logged in the right place, it might belong against poppler. I can't see any duplicate bugs, but apologies if so, I don't know what I am doing. So, many PDFs render fine for me, but some produce terribly blocky text. I don't have any examples that I can redistribute, but any journal article downloaded from www.jstor.org seems to exhibit the problem. I have have done some research to try and figure out what is going on. The following bug reports against ubuntu and arch-linux seem to repeat what I see, and suggest it is to do with a conflict between application anti-aliasing and freetype autohinting when pdfs include embedded fonts, and that some packages (poppler derived) don't use fontconfig and so a simple dpkg-reconfigure fontconfig-config is not enough. See: https://bugs.launchpad.net/ubuntu/+source/poppler/+bug/48146 http://groups.google.cl/group/arch-linux/browse_thread/thread/5402873a6e65c151 A patch is suggested in the ubuntu thread (against poppler) that disables freetype autohinting at compile time. I have not tried applying and recompiling for a range of reasons not worth exploring. It is as follows: --- poppler-0.6.4/splash/SplashFTFont.cc.-hinting 2008-01-21 22:59:14.000000000 +0300 +++ poppler-0.6.4/splash/SplashFTFont.cc 2008-12-18 17:21:04.000000000 +0300 @@ -180,7 +180,7 @@ } // if we have the FT2 bytecode interpreter, autohinting won't be used -#ifdef TT_CONFIG_OPTION_BYTECODE_INTERPRETER +#if 0 if (FT_Load_Glyph(ff->face, gid, aa ?
