Module Vg.Font

module Font: sig .. end

Font handling in Vg happens in renderers and text layout and text to glyph translations are expected to be carried out by an external library. Values of type Vg.font just represent a font specification to be resolved by the concrete renderer.


type weight = [ `W100 | `W200 | `W300 | `W400 | `W500 | `W600 | `W700 | `W800 | `W900 ] 
The type for font weights. Usually `W400 denotes a normal weight and `W700, a bold weight.
type slant = [ `Italic | `Normal | `Oblique ] 
The type for font slants.
type t = {
   name : string;
   slant : slant;
   weight : weight;
   size : float;
The type for fonts. The size is expressed in Vg's coordinate space, the em unit of the font is scaled to that size.

Predicates and comparisons

val equal : t -> t -> bool
equal font font' is font = font'.
val equal_f : (float -> float -> bool) -> t -> t -> bool
equal_f eq font font' is like Vg.Font.equal but uses eq to test floating point values.
val compare : t -> t -> int
compare font font' is font font'
val compare_f : (float -> float -> int) -> t -> t -> int
compare_f cmp font font' is like but uses cmp to compare floating point values.


val to_string : t -> string
to_string font is a textual representation of font.
val pp : Format.formatter -> t -> unit
pp ppf font is a textual representation of font on ppf.
