## ◆ info()

bool CRM64Pro::FontMgr::info | ( | Sint32 | iMode = 0 | ) |
| override

Request Font Manager information.

  true on success, or false on failure.

## ◆ create()

Sint32 CRM64Pro::FontMgr::create | ( | const string & | sName,
|  | Uint32 | iVersion = 10 )
| override

Create a new font.

This method will create an empty font (no image assigned), use Font::assignImage() method for assigning the image.

Returns
  Greater than 0 on success (the Font id) or a negative error code on failure.

| override
