The Type 1 and CID drivers


It is possible to control the behaviour of FreeType's Type 1 and Type 1 CID drivers with FT_Property_Set and FT_Property_Get.

Behind the scenes, both drivers use the Adobe CFF engine for hinting; however, the used properties must be specified separately.

The Type 1 driver's module name is ‘type1’; the CID driver's module name is ‘t1cid’.

Available properties are hinting-engine, no-stem-darkening, darkening-parameters, and random-seed, as documented in the ‘Driver properties’ section.

Please see the ‘The CFF driver’ section for more details on the new hinting engine.
