Function Documentation

gp_font_face_lookup()

const gp_font_face * gp_font_face_lookup	(	const char *	family_name,
		uint8_t	style )

Looks up a font face in a family given a family name and style flags.

Parameters

family_name	A family name such as 'gfxprim', 'tiny', etc.
style	A bitmask of enum gp_font_style. If GP_FONT_FALLBACK is passed the function never returns NULL.

Returns

A pointer to a font family or NULL if not found.

gp_font_family_face_lookup()

const gp_font_face * gp_font_family_face_lookup	(	const gp_font_family *	family,
		uint8_t	style )

Looks up a font face in a family given a style flags.

If family pointer is a null default 'gfxprim' family is used instead.

Parameters

family	A pointer to a font family. If NULL is passed default is used.
style	A bitmask of enum gp_font_style. If GP_FONT_FALLBACK is passed the function never returns NULL.

Returns

A pointer to a font or NULL if not found.

gp_font_family_lookup()

const gp_font_family * gp_font_family_lookup

(

const char *

family_name

)

Font family lookup.

Looks up a font family by a family name in the compiled in fonts.

Parameters

family_name

A family name, such as 'gfxprim', 'tiny', etc.

Returns

A pointer to a font family or NULL if not found.

gp_fonts_iter_family()

const gp_font_family * gp_fonts_iter_family	(	gp_fonts_iter *	iter,
		int	wrap,
		enum gp_fonts_iter_dir	dir )

Iterates over all compiled in families.

Parameters

iter	An iterator.
wrap	If non zero makes the iteration circular, i.e. NULL is not returned at the end.
dir	Direction to move to.

Returns

Current font family.

gp_fonts_iter_font()

const gp_font_face * gp_fonts_iter_font	(	gp_fonts_iter *	iter,
		int	wrap,
		enum gp_fonts_iter_dir	dir )

Iterates over all compiled in fonts.

Parameters

iter	An iterator.
wrap	If non zero makes the iteration circular, i.e. NULL is not returned at the end.
dir	Direction to move to.

Returns

A font face.
