class TGLFont

 TGLFont

 A wrapper class for FTFont.
 Holds pointer to FTFont object and its description: face size, font file
 and class ID. It  wraps Render and BBox functions.

Function documentation

TGLFont()

 Constructor.

TGLFont(Int_t size, Int_t font, TGLFont::EMode mode, FTFont* f = 0, TGLFontManager* mng = 0)

 Constructor.

TGLFont(const TGLFont& o)

 Assignment operator.

~TGLFont()

Destructor

void CopyAttributes(const TGLFont& o)

 Assignment operator.

Float_t GetAscent() const

 Get font's ascent.

Float_t GetDescent() const

 Get font's descent. The returned value is positive.

Float_t GetLineHeight() const

 Get font's line-height.

void MeasureBaseLineParams(Float_t& ascent, Float_t& descent, Float_t& line_height, const char* txt = "Xj") const

 Measure font's base-line parameters from the passed text.
 Note that the measured parameters are not the same as the ones
 returned by get-functions - those were set by the font designer.

void BBox(const char* txt, Float_t& llx, Float_t& lly, Float_t& llz, Float_t& urx, Float_t& ury, Float_t& urz) const

 Get bounding box.

void Render(const char* txt, Double_t x, Double_t y, Double_t angle, Double_t mgn) const

mgn is simply ignored, because ROOT's TVirtualX TGX11 are complete mess with
painting attributes.

void Render(const TString& txt) const

 Render text.

void PreRender(Bool_t autoLight = kTRUE, Bool_t lightOn = kFALSE) const

 Set-up GL state before FTFont rendering.

void PostRender() const

 Reset GL state after FTFont rendering.

void SetTrashCount(Int_t c) const
