Provides access to the underlying C instance. | |
const PangoCoverage* | gobj () const |
Provides access to the underlying C instance. | |
PangoCoverage* | gobj_copy () const |
Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs. | |
CoverageLevel | get (int index) const |
Determine whether a particular index is covered by coverage. | |
void | set (int index, CoverageLevel level) |
Modify a particular index within coverage. | |
void | max (const Glib::RefPtr< Coverage >& other) const |
Set the coverage for each index in coverage to be the max (better) value of the current coverage for the index and the coverage for the corresponding index in other. | |
Glib::ArrayHandle< unsigned char > | to_bytes () const |
Convert the coverage map into a flat binary format. | |

Glib::RefPtr< Pango::Coverage > | wrap (PangoCoverage* object, bool take_copy=false) |
A Glib::wrap() method for this object. |
It is often necessary in pango to determine if a particular font can represent a particular character, and also how well it can represent that character. Pango::Coverage holds this information.
