Module `Mlpost__Metric`

A high-level interface for Font metrics

type t = Mlpost__.Tfm.t

val char_width : t -> int -> float: char_width t i returns the width of the ith character of the font metric t, 0 is the first character

val char_height : t -> int -> float: same as char_width, but for character height

val char_depth : t -> int -> float: same as char_width, but for character depth

val char_italic : t -> int -> float

same as char_width, but for character depth

same as char_width, but for italic correction of the character

val char_dims : t -> int -> float * float * float: char_dims metric i returns the width, height and depth of the ith char, slightly more efficient than invoking the other functions three times

val slant : t -> float: is the amount of italic slant, which is used to help position accents. For example, slant=.25 means that when you go up one unit, you also go .25 units to the right.

val space : t -> float: is the normal spacing between words in text. Note that character " " in the font need not have anything to do with blank spaces.

val space_stretch : t -> float: is the amount of glue stretching between words.

val space_shrink : t -> float: is the amount of glue shrinking between words.

val x_height : t -> float: is the height of letters for which accents don't have to be raised or lowered.

val quad : t -> float: is the size of one em in the font.

val extra_space : t -> float

is the size of one em in the font.

is the amount added to space at the ends of sentences.
