Typedef Documentation

◆ hb_ot_var_axis_info_t

typedef struct hb_ot_var_axis_info_t hb_ot_var_axis_info_t

hb_ot_var_axis_info_t: @axis_index: Index of the axis in the variation-axis array @tag: The hb_tag_t tag identifying the design variation of the axis @name_id: The name table Name ID that provides display names for the axis @flags: The hb_ot_var_axis_flags_t flags for the axis @min_value: The minimum value on the variation axis that the font covers @default_value: The position on the variation axis corresponding to the font's defaults @max_value: The maximum value on the variation axis that the font covers

Data type for holding variation-axis values.

The minimum, default, and maximum values are in un-normalized, user scales.

<note>Note: at present, the only flag defined for @flags is HB_OT_VAR_AXIS_FLAG_HIDDEN.</note>

Since: 2.2.0
