|
---|
| 9 | * opaque handle that is translated to an internal representation when used by
|
---|
| 10 | * other managers. The internal representation used for a given Font handle is
|
---|
| 11 | * implementation-specific (i.e. if an exact match for the font handle is not registered
|
---|
| 12 | * with the manager, the alternative selected is undefined).
|
---|
| 13 | *
|
---|
| 14 | * TTF font files can be registered with the manager to increase the range of internal
|
---|
| 15 | * fonts available, and a collection of handles to all of the fonts the manager supports
|
---|
| 16 | * can be requested.
