The Irrlicht FIGDriver is a superfont (metafont?), that is an IGUIFont which is composed of other IGUIFonts. It allows the user to load FIGlet fonts from JavE, the ASCII equivalent of Photoshop:
To load a font you simply do something like this:
// First use the Irrlicht font tool to generate a fixed-width font,
// use the one provided, or the Console device's built-in font.
IGUIFont* font = guienv->getFont("fixed.xml");
// create an instance of a figlet font
CGUIFIGletFont* figFont = new CGUIFIGletFont(font);
// open a FIGlet file for reading
io::IReadFile* file
= device->getFileSystem()->createAndOpenFile("figlets/big.flf");
// load the font data
figFont->load(file);
// set the font to the skin's default font
guienv->getSkin()->setFont(figFont);
// remember to drop the things you created!
file->drop();
figFont->drop();
// all done!
