public:

TTF
Interface to the freetype 2 library.
~TTF()
Cleanup TTF environment.
void Init()
Initialise the TrueType fonts interface.
void Cleanup()
Cleanup. Is called by the gCleanupTTF destructor.
Short_t CharToUnicode(UInt_t code)
Map char to unicode. Returns 0 in case no mapping exists.
void GetTextExtent(UInt_t &w, UInt_t &h, char *text)
Get width (w) and height (h) when text is horizontal.
void LayoutGlyphs()
Compute the glyps positions, fgAscent and fgWidth (needed for alignment).
Perform the Glyphs transformation.
Compute the string control box.
If required take the "kerning" into account.
SetRotation and PrepareString should have been called before.
void PrepareString(const char *string)
Put the characters in "string" in the "glyphs" array.
void SetHinting(Bool_t state)
Set hinting flag.
void SetKerning(Bool_t state)
Set kerning flag.
void SetRotationMatrix(Float_t angle)
Set the rotation matrix used to rotate the font outlines.
void SetSmoothing(Bool_t state)
Set smoothing (anti-aliasing) flag.
Int_t SetTextFont(const char *fontname)
Set text font to specified name.
font : font name
Set text font to specified name. This function returns 0 if
the specified font is found, 1 if not.
void SetTextFont(Font_t fontnumber)
Set specified font.
