Expand description

Feature parameter data.

Certain OpenType features may have various ancillary data attached to them. The format of this data varies from feature to feature, so this container wraps the general concept of feature parameter data.

Variants

StylisticSet(uint16, uint16)

The stylistic set features (ss01-ss20) may provide two parameters: a parameter data version, currently set to zero, and a name table ID which is used to display the stylistic set name to the user.

SizeFeature(sizeFeatureParams)

Feature parameter information for the size feature, including the design size, subfamily identifier and name ID, and largest and smallest intended sizes. This has been superseded by the STAT table.

CharacterVariant(cvFeatureParams)

The character variant features (cv01-cv99) provide various name parameters to display information to the user.
