get_resolution
Description:
Gets the resolution for font handling on the screen.
The resolution is a scale factor between points specified in a FontDescription and cairo units. The default value is 96.0, meaning that a 10 point font will be 13 units high (10 * 96. / 72. = 13.3).
Clutter will set the resolution using the current backend when initializing; the resolution is also stored in the font_dpi property.
Parameters:
| this |
a Backend |
Returns:
|
the current resolution, or -1 if no resolution has been set. |
