| * @description: |
| * Thanks to Adobe, which contributed a new hinting (and parsing) |
| * engine, an application can select between `freetype' and `adobe' if |
| * compiled with T1_CONFIG_OPTION_OLD_ENGINE. If this configuration |
| * macro isn't defined, `hinting-engine' does nothing. |
| * |
| * The default engine is `freetype' if T1_CONFIG_OPTION_OLD_ENGINE is |
| * defined, and `adobe' otherwise. |
| * |
| * The following example code demonstrates how to select Adobe's hinting |
| * engine (omitting the error handling). |
| * |
| * { |
| * FT_Library library; |
| * FT_UInt hinting_engine = FT_T1_HINTING_ADOBE; |
| * |
| * |
| * FT_Init_FreeType( &library ); |
| * |
| * FT_Property_Set( library, "type1", |
| * "hinting-engine", &hinting_engine ); |
| * } |
| * |
| * @note: |
| * This property can be used with @FT_Property_Get also. |
| * |
| * This property can be set via the `FREETYPE_PROPERTIES' environment |
| * variable (using values `adobe' or `freetype'). |
