Freetype
val init : unit -> t
init ()
initializes the Freetype library. The returned library is required to load fonts.
type face_info = {
}
new_face library fontfile n
loads n
-th font stored in the font file fontfile
, and returns its face and face information.
val get_num_glyphs : face -> int
Returns number of glyphs stored in the face. Equivalent to face_info.num_glyphs
val 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)
val 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.
