This page shows text rendering with various types of lcd filtering parameters. The pango-view util from Pango was used to generate the images. Cairo is patched with the lcd filtering patch (https://bugs.freedesktop.org/show_bug.cgi?id=10301) and a modification to read lcd filtering parameters from fontconfig.

You must have a LCD screen with RGB pixel order, otherwise the images won't make sense. First part of the page is done with the bytecode interpreter turned on and the second part with the autohinter.
