Module `Freetype`Source

Sourcetype t

type for Freetype library

Sourceval init : unit -> t

init () initializes the Freetype library. The returned library is required to load fonts.

Sourcetype face

Type for face

Sourcetype face_info = {

num_faces : int;
num_glyphs : int;
family_name : string;
style_name : string;
has_horizontal : bool;
has_vertical : bool;
has_kerning : bool;
is_scalable : bool;
is_sfnt : bool;
is_fixed_width : bool;
has_fixed_sizes : bool;
has_fast_glyphs : bool;
has_glyph_names : bool;
has_multiple_masters : bool;

}

Sourceval new_face : t -> string -> int -> face * face_info

new_face library fontfile n loads n-th font stored in the font file fontfile, and returns its face and face information.

Sourceval get_num_glyphs : face -> int

Returns number of glyphs stored in the face. Equivalent to face_info.num_glyphs

Sourceval set_char_size : face -> float -> float -> int -> int -> unit

set_char_size face charw charh resh resv sets the character size of face. charw and charh are the points of the characters in width and height. resh and resv are the horizontal and vertical resolution (in dpi)

Sourceval set_pixel_sizes : face -> int -> int -> unit

set_pixel_sizes face pixw pixh also sets the character size of face. pixw and pixh are standard width and height of characters in pixels.

Sourcetype charmap = {

platform_id : int;
encoding_id : int;

}

Sourcetype char_index

Sourceval int_of_char_index : char_index -> int

Sourceval char_index_of_int : int -> char_index
