Hmm, with auto-hinting active it is rather *expected* to get bad B/W hinting, so this is the wrong route. Attached is a script which builds FreeType with and without subpixel hinting in development mode (from the git repositories), then taking snapshots in B/W mode. While testing the script, I've used Windows 7's arial.ttf (version 5.10), but the results are the same as before. You need `xdotool' and ImageMagick, BTW. Werner
#!/bin/sh # # Using X11, make two snapshots from `ftview' in B/W mode, with and without # compile-time macro TT_CONFIG_OPTION_SUBPIXEL_HINTING. # # This script uses the FreeType git repositories, compiling the programs # with development options in a temporary directory (`fttest.XXX'). # # You need the `xdotool' program to send X11 keyboard events and to get # Window IDs (note that some versions of `xdotool' are buggy, not correctly # understanding the `--pid' option; it is thus assumed that there is no # ftview window opened when running this script) # # Images are created with ImageMagick's `import' tool; after the script has # finished, you can find them in the top level of the temporary directory. # Adjust to your setup.
