Glib::RefPtr<Context> Pango::CairoFontMap::create_context | ( | ) |
Create a Pango::Context for the given fontmap.
- Returns:
- The newly created context; free with Glib::object_unref().
Cairo::FontType Pango::CairoFontMap::get_font_type | ( | ) | const |
Gets the type of Cairo font backend that fontmap uses.
- Returns:
- The cairo_font_type_t cairo font backend type
double Pango::CairoFontMap::get_resolution | ( | ) | const |
Gets the resolution for the fontmap.
See set_resolution()
- Returns:
- The resolution in "dots per inch"

PangoCairoFontMap* Pango::CairoFontMap::gobj | ( | ) | [inline] |
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).
Since: 1.10
- Parameters:
-
dpi The resolution in "dots per inch". (Physical inches aren't actually involved; the terminology is conventional.).
Friends And Related Function Documentation
Glib::RefPtr<Pango::CairoFontMap> wrap | ( | PangoCairoFontMap * | object, | |
bool | take_copy = false | |||
) | [related] |
A Glib::wrap() method for this object.
- Parameters:
-
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.
- Returns:
- A C++ instance that wraps this C instance.
