PangoCairoFontMap* Pango::CairoFontMap::gobj | ( | ) | [inline] |
Provides access to the underlying C GObject.
Reimplemented from Glib::Interface.
const PangoCairoFontMap* Pango::CairoFontMap::gobj | ( | ) | const [inline] |
Provides access to the underlying C GObject.
Reimplemented from Glib::Interface.
void Pango::CairoFontMap::set_default | ( | ) |
Sets a default Pango::CairoFontMap to use with Cairo.
This can be used to change the Cairo font backend that the default fontmap uses for example. The old default font map is unreffed and the new font map referenced.
A value of 0
for fontmap will cause the current default font map to be released and a new default font map to be created on demand, using new().
void Pango::CairoFontMap::set_resolution | ( | double | dpi ) |
Sets the resolution for the fontmap.
This is a scale factor between points specified in a Pango::FontDescription and Cairo units. The default value is 96, meaning that a 10 point font will be 13 units high. (10* 96. / 72. = 13.3).
dpi | The resolution in "dots per inch". (Physical inches aren't actually involved; the terminology is conventional.). |
Glib::RefPtr< Pango::CairoFontMap > wrap | ( | PangoCairoFontMap * | object, |
bool | take_copy = false |
||
) | [related] |
A Glib::wrap() method for this object.
object | The C instance. |
take_copy | False if the result should take ownership of the C instance. True if it should take a new copy or ref. |
