) |
Set the font family or filename, and size on a given text object.
This function allows the font name and size of a text object to be set. The font
string has to follow fontconfig's convention on naming fonts, as it's the underlying library used to query system fonts by Evas (see the fc-list
command's output, on your system, to get an idea). Alternatively, one can use a full path to a font file.

) |
Retrieve the font family and size in use on a given text object.
This function allows the font name and size of a text object to be queried. Be aware that the font name string is still owned by Evas and should not have free() called on it by the caller of the function.
[out] | font | The font family name or filename. |
[out] | size | The font size, in points. |
