Function Documentation

◆ ft_char_index()

int ft_char_index	(	void *	face,
		int	cid )

◆ ft_error_string()

const char * ft_error_string ( int err )

map an FT error number to a static string.

err: The error number to lookup.

Returns a pointer to a static textual representation of a freetype error.

◆ ft_name_index()

int ft_name_index	(	void *	face,
		const char *	name )

◆ fz_advance_glyph()

float fz_advance_glyph	(	fz_context *	ctx,
		fz_font *	font,
		int	glyph,
		int	wmode )

Return the advance for a given glyph.

font: The font to look for the glyph in.

glyph: The glyph to find the advance for.

wmode: 1 for vertical mode, 0 for horizontal.

Returns the advance for the glyph.

◆ fz_bound_glyph()

fz_rect fz_bound_glyph	(	fz_context *	ctx,
		fz_font *	font,
		int	gid,

gid: The glyph to bound.

trm: The matrix to apply to the glyph before bounding.

Returns rectangle by value containing the bounds of the given glyph.

◆ fz_calculate_font_ascender_descender()

void fz_calculate_font_ascender_descender	(	fz_context *	ctx,
		fz_font *	font )

Ensure that a font has its ascender/descender values calculated from the actual bbox of the glyphs.

Note, that we combine the declared values from the font (or the default values if those are not present) with the actual bbox to get the final result. So this can only cause ascender/descender to move further apart!

◆ fz_decouple_type3_font()

void fz_decouple_type3_font	(	fz_context *	ctx,
		fz_font *	font,
		void *	t3doc )

◆ fz_drop_font()

Returns the glyph id for the given unicode value, or 0 if unknown.

◆ fz_encode_character_by_glyph_name()

int fz_encode_character_by_glyph_name	(	fz_context *	ctx,
		fz_font *	font,
		const char *	glyphname )

Encode character.

Either by direct lookup of glyphname within a font, or, failing that, by mapping glyphname to unicode and thence to the glyph index within the given font.

Returns zero for type3 fonts.

◆ fz_encode_character_sc()

int fz_encode_character_sc	(	fz_context *	ctx,
		fz_font *	font,

int fz_encode_character_with_fallback	(	fz_context *	ctx,
		fz_font *	font,

Find the glyph id for a given unicode character within a font, falling back to an alternative if not found.

font: The font to look for the unicode character in.

unicode: The unicode character to encode.

script: The script in use.

language: The language in use.

out_font: The font handle in which the given glyph represents the requested unicode character. The caller does not own the reference it is passed, so should call fz_keep_font if it is not simply to be used immediately.

Returns the glyph id for the given unicode value in the supplied font (and sets *out_font to font) if it is present. Otherwise an alternative fallback font (based on script/language) is searched for. If the glyph is found therein, *out_font is set to this reference, and the glyph reference is returned. If it cannot be found anywhere, the function returns 0.
