Cairo.Font_face.t
represents a particular font at a particular weight, slant, and other characteristic but no size, transformation, or size.
A Cairo.Font_face.t
specifies all aspects of a font other than the size or font matrix (a font matrix is used to distort a font by sheering it or scaling it unequally in the two directions). A font face can be set on a Cairo.context
by using Cairo.Font_face.set
; the size and font matrix are set with Cairo.set_font_size
and Cairo.set_font_matrix
.
Font faces are created using font-backend-specific constructors, or implicitly using the toy text API by way of Cairo.select_font_face
.
There are various types of font faces, depending on the font backend they use. The type of a font face can be queried using Cairo.Font_face.get_type
.
Replaces the current Cairo.Font_face.t
object in the Cairo.context
with font_face.
Gets the current font face for a Cairo.context
.
This function returns the type of the backend used to create a font face. See Cairo.font_type
for available types. If 'a
contains a single variant, it will be the returned value.
create family slant weight
creates a font face from a triplet of family, slant, and weight. These font faces are used in implementation of the the cairo "toy" font API.
If family is not given or is the zero-length string "", the platform-specific default family is assumed. The default family then can be queried using Cairo.Font_face.get_family
.
The Cairo.select_font_face
function uses this to create font faces. See that function for limitations of toy font faces.
val get_family : [ `Toy ] t -> string
Gets the familly name of a toy font.
