Typedef Documentation

hb_face_t

typedef struct hb_face_t hb_face_t

hb_face_t:

Data type for holding font faces.

Definition at line 56 of file hb-face.h.

hb_get_table_tags_func_t

typedef unsigned int(* hb_get_table_tags_func_t) (const hb_face_t *face, unsigned int start_offset, unsigned int *table_count, hb_tag_t *table_tags, void *user_data)

hb_get_table_tags_func_t: @face: A face object @start_offset: The index of first table tag to retrieve @table_count: (inout): Input = the maximum number of table tags to return; Output = the actual number of table tags returned (may be zero) @table_tags: (out) (array length=table_count): The array of table tags found @user_data: User data pointer passed by the caller

Callback function for hb_face_get_table_tags().

Return value: Total number of tables, or zero if it is not possible to list

Since: 10.0.0

Definition at line 154 of file hb-face.h.

hb_reference_table_func_t

typedef hb_blob_t *(* hb_reference_table_func_t) (hb_face_t *face, hb_tag_t tag, void *user_data)

hb_reference_table_func_t: @face: an hb_face_t to reference table for @tag: the tag of the table to reference @user_data: User data pointer passed by the caller

Callback function for hb_face_create_for_tables().

Return value: (transfer full): A pointer to the @tag table within @face

Since: 0.9.2

Definition at line 75 of file hb-face.h.
