|
|
* USER-SELECTABLE CONFIGURATION MACROS
|
|
*
|
|
* This file contains the default configuration macro definitions for
|
|
* a standard build of the FreeType library. There are three ways to
|
|
* use this file to build project-specific versions of the library:
|
|
*
|
|
* - You can modify this file by hand, but this is not recommended in
|
|
* cases where you would like to build several versions of the
|
|
* library from a single source directory.
|
|
*
|
|
* - You can put a copy of this file in your build directory, more
|
|
* precisely in `$BUILD/freetype/config/ftoption.h', where `$BUILD'
|
|
* is the name of a directory that is included _before_ the FreeType
|
|
* include path during compilation.
|
|
*
|
|
* The default FreeType Makefiles and Jamfiles use the build
|
|
* directory `builds/<system>' by default, but you can easily change
|
|
* that for your own projects.
|
|
*
|
|
* - Copy the file <ft2build.h> to `$BUILD/ft2build.h' and modify it
|
|
* slightly to pre-define the macro FT_CONFIG_OPTIONS_H used to
|
|
* locate this file during the build. For example,
|
|
*
|
|
* #define FT_CONFIG_OPTIONS_H <myftoptions.h>
|
|
* #include <freetype/config/ftheader.h>
|
|
*
|
|
* will use `$BUILD/myftoptions.h' instead of this file for macro
|
|
* definitions.
|
|
*
|
|
* Note also that you can similarly pre-define the macro
|
|
* FT_CONFIG_MODULES_H used to locate the file listing of the modules
|
|
* that are statically linked to the library at compile time. By
|
|
* default, this file is <freetype/config/ftmodule.h>.
|
|
*
|
|
* We highly recommend using the third method whenever possible.

|
* subpixel hinting support into the TrueType driver. This modifies the
|
|
* TrueType hinting mechanism when anything but FT_RENDER_MODE_MONO is
|
|
* requested.
|
|
*
|
|
* In particular, it modifies the bytecode interpreter to interpret (or
|
|
* not) instructions in a certain way so that all TrueType fonts look
|
|
* like they do in a Windows ClearType (DirectWrite) environment. See
|
|
* [1] for a technical overview on what this means. See `ttinterp.h'
|
|
* for more details on the LEAN option.
|
|
*
|
|
* There are three options.
|
|
*
|
|
* 1. This option is associated with the `Infinality' moniker.
|
|
* Contributed by an individual nicknamed Infinality with the goal of
|
|
* making TrueType fonts render better than on Windows. A high
|
|
* amount of configurability and flexibility, down to rules for
|
|
* single glyphs in fonts, but also very slow. Its experimental and
|
|
* slow nature and the original developer losing interest meant that
|
|
* this option was never enabled in default builds.
|
|
*
|
|
* 2. The new default mode for the TrueType driver. The Infinality code
|
|
* base was stripped to the bare minimum and all configurability
|
|
* removed in the name of speed and simplicity. The configurability
|
|
* was mainly aimed at legacy fonts like Arial, Times New Roman, or
|
|
* Courier. Legacy fonts are fonts that modify vertical stems to
|
|
* achieve clean black-and-white bitmaps. The new mode focuses on
|
|
* applying a minimal set of rules to all fonts indiscriminately so
|
|
* that modern and web fonts render well while legacy fonts render
|
|
* okay.
|
|
*
|
|
* 3. Compile both.
|
|
*
|
|
* By undefining these, you get rendering behavior like on Windows
|
|
* without ClearType, i.e., Windows XP without ClearType enabled and
|
|
* Win9x (interpreter version v35). Or not, depending on how much
|
|
* hinting blood and testing tears the font designer put into a given
|
|
* font. If you define one or both subpixel hinting options, you can
|
|
* switch between between v35 and the ones you define.
|
|
*
|
|
* This option requires TT_CONFIG_OPTION_BYTECODE_INTERPRETER to be
|
|
* defined.
