|

|
| - * *Experimental* *only*
|
| - *
|
| - * The auto-hinter provides various script modules to hint glyphs.
|
| - * Examples of supported scripts are Latin or CJK. Before a glyph is
|
| - * auto-hinted, the Unicode character map of the font gets examined, and
|
| - * the script is then determined based on Unicode character ranges, see
|
| - * below.
|
| - *
|
| - * OpenType fonts, however, often provide much more glyphs than
|
| - * character codes (small caps, superscripts, ligatures, swashes, etc.),
|
| - * to be controlled by so-called `features'. Handling OpenType features
|
| - * can be quite complicated and thus needs a separate library on top of
|
| - * FreeType.
|
| - *
|
| - * The mapping between glyph indices and scripts (in the auto-hinter
|
| - * sense, see the @FT_AUTOHINTER_SCRIPT_XXX values) is stored as an
|
| - * array with `num_glyphs' elements, as found in the font's @FT_Face
|
| - * structure. The `glyph-to-script-map' property returns a pointer to
|
| - * this array, which can be modified as needed. Note that the
|
| - * modification should happen before the first glyph gets processed by
|
| - * the auto-hinter so that the global analysis of the font shapes
|
| - * actually uses the modified mapping.
|
| - *
|
| - * The following example code demonstrates how to access it (omitting
|
| - * the error handling).
|
| - *
|
| - * {
|
| - * FT_Library library;
|
