| 1 | | This version of Freetype has made some changes in the support of subpixel hinting, which results in a compile error if the book's sed command to uncomment the SUBPIXEL defines is used as-is. The TT_CONFIG_OPTION_SUBPIXEL_HINTING define is now expected to be followed by a number, either "1", "2", or "3", for different ways of performing subpixel hinting. The default is to define option "2". Personally, I don't know enough about font rendering to understand the difference between those options, so for my own build scripts I just don't edit the SUBPIXEL_HINTING option and accept the default. Here's the relevant portion of ftoption.h: |
