Description

jpayne@68:

The font options specify how fonts should be rendered. Most of the jpayne@68: time the font options implied by a surface are just right and do not jpayne@68: need any changes, but for pixel-based targets tweaking font options jpayne@68: may result in superior output on a particular display.

cairo_font_options_create ()

jpayne@68: 
cairo_font_options_t *
jpayne@68: cairo_font_options_create (void);
jpayne@68:

Allocates a new font options object with all options initialized jpayne@68: to default values.

jpayne@68:
jpayne@68:

Returns

jpayne@68:

a newly allocated cairo_font_options_t. Free with jpayne@68: cairo_font_options_destroy(). This function always returns a jpayne@68: valid pointer; if memory cannot be allocated, then a special jpayne@68: error object is returned where all operations on the object do nothing. jpayne@68: You can check for this with cairo_font_options_status().

void
jpayne@68: cairo_font_options_set_variations (cairo_font_options_t *options,
jpayne@68:                                    const char *variations);
jpayne@68:

Sets the OpenType font variations for the font options object. jpayne@68: Font variations are specified as a string with a format that jpayne@68: is similar to the CSS font-variation-settings. The string contains jpayne@68: a comma-separated list of axis assignments, which each assignment jpayne@68: consists of a 4-character axis name and a value, separated by jpayne@68: whitespace and optional equals sign.

cairo_font_options_t

jpayne@68: 
typedef struct _cairo_font_options cairo_font_options_t;
jpayne@68:
jpayne@68:

An opaque structure holding all options that are used when jpayne@68: rendering fonts.

jpayne@68:

Individual features of a cairo_font_options_t can be set or jpayne@68: accessed using functions named jpayne@68: cairo_font_options_set_feature_name() and jpayne@68: cairo_font_options_get_feature_name(), like jpayne@68: cairo_font_options_set_antialias() and jpayne@68: cairo_font_options_get_antialias().

jpayne@68:

New features may be added to a cairo_font_options_t in the jpayne@68: future. For this reason, cairo_font_options_copy(), jpayne@68: cairo_font_options_equal(), cairo_font_options_merge(), and jpayne@68: cairo_font_options_hash() should be used to copy, check jpayne@68: for equality, merge, or compute a hash value of jpayne@68: cairo_font_options_t objects.

enum cairo_hint_style_t

jpayne@68:

Specifies the type of hinting to do on font outlines. Hinting jpayne@68: is the process of fitting outlines to the pixel grid in order jpayne@68: to improve the appearance of the result. Since hinting outlines jpayne@68: involves distorting them, it also reduces the faithfulness jpayne@68: to the original outline shapes. Not all of the outline hinting jpayne@68: styles are supported by all font backends.

jpayne@68:

New entries may be added in future versions.

enum cairo_hint_metrics_t

jpayne@68:

Specifies whether to hint font metrics; hinting font metrics jpayne@68: means quantizing them so that they are integer values in jpayne@68: device space. Doing this improves the consistency of jpayne@68: letter and line spacing, however it also means that text jpayne@68: will be laid out differently at different zoom factors.
