Class Description

 Graphics interface to SVG.                                           

 Default SVG constructor
TSVG(const char *fname, Int_t wtype)
 Initialize the SVG interface

  fname : SVG file name
  wtype : SVG workstation type. Not used in the SVG driver. But as TSVG
          inherits from TVirtualPS it should be kept. Anyway it is not
          necessary to specify this parameter at creation time because it
          has a default value (which is ignore in the SVG case).
void Open(const char *fname, Int_t wtype)
 Open a SVG file
 Default SVG destructor
void Close(Option_t *)
 Close a SVG file
void On()
 Activate an already open SVG file
void Off()
 Deactivate an already open SVG file
void DrawBox(Double_t x1, Double_t y1, Double_t x2, Double_t y2)
 Draw a Box
void DrawFrame(Double_t xl, Double_t yl, Double_t xt, Double_t yt, Int_t mode, Int_t border, Int_t dark, Int_t light)
 Draw a Frame around a box

 mode = -1  the box looks as it is behind the screen
 mode =  1  the box looks as it is in front of the screen
 border is the border size in already pre-computed SVG units dark is the
 color for the dark part of the frame light is the color for the light
 part of the frame
void DrawPolyLine(Int_t nn, TPoints *xy)
 Draw a PolyLine

  Draw a polyline through  the points  xy.
  If NN=1 moves only to point x,y.
  If NN=0 the x,y are  written  in the SVG        file
     according to the current transformation.
  If NN>0 the line is clipped as a line.
  If NN<0 the line is clipped as a fill area.
void DrawPolyLineNDC(Int_t nn, TPoints *xy)
 Draw a PolyLine in NDC space

  Draw a polyline through  the points  xy.
  If NN=1 moves only to point x,y.
  If NN=0 the x,y are  written  in the SVG        file
     according to the current transformation.
  If NN>0 the line is clipped as a line.
  If NN<0 the line is clipped as a fill area.
void DrawPolyMarker(Int_t n, Float_t *xw, Float_t *yw)
 Paint PolyMarker
void DrawPolyMarker(Int_t n, Double_t *xw, Double_t *yw)
 Paint PolyMarker
void DrawPS(Int_t nn, Double_t *xw, Double_t *yw)
 This function defines a path with xw and yw and draw it according the
 value of nn:

  If nn>0 a line is drawn.
  If nn<0 a closed polygon is drawn.
void Initialize()
 Initialize the SVG file. The main task of the function is to ouput the
 SVG header file which consist in <title>, <desc> and <defs>. The
 HeaderPS provided by the user program is written in the <defs> part.
void MovePS(Int_t ix, Int_t iy)
 Move to a new position (ix, iy). The move is done in relative coordinates
 which allows to have short numbers which decrease the size of the file.
 This function use the full power of the SVG's paths by using the
 horizontal and vertical move whenever it is possible.
void NewPage()
 Start the SVG page. This function initialize the pad conversion
 coefficients and ouput the <svg> directive which is close later in the
 the function Close.
void Range(Float_t xsize, Float_t ysize)
 Set the range for the paper in centimetres
void SetFillColor( Color_t cindex )
 Set color index for fill areas
void SetLineColor( Color_t cindex )
 Set color index for lines
void SetLineStyle(Style_t linestyle)
 Change the line style

 linestyle = 2 dashed
           = 3 dotted
           = 4 dash-dotted
           = else solid (1 in is used most of the time)
void SetLineWidth(Width_t linewidth)
 Set the lines width.
void SetMarkerColor( Color_t cindex )
 Set color index for markers.
void SetColor(Int_t color)
 Set color with its color index
void SetColor(Float_t r, Float_t g, Float_t b)
 Set color with its R G B components

  r: % of red in [0,1]
  g: % of green in [0,1]
  b: % of blue in [0,1]
void SetTextColor( Color_t cindex )
 Set color index for text
void Text(Double_t xx, Double_t yy, const char *chars)
 Draw text

 xx: x position of the text
 yy: y position of the text
 chars: text to be drawn
void TextNDC(Double_t u, Double_t v, const char *chars)
 Write a string of characters in NDC
Int_t UtoSVG(Double_t u)
 Convert U from NDC coordinate to SVG
Int_t VtoSVG(Double_t v)
 Convert V from NDC coordinate to SVG
Int_t XtoSVG(Double_t x)
 Convert X from world coordinate to SVG
Int_t YtoSVG(Double_t y)
 Convert Y from world coordinate to SVG
void CellArrayBegin(Int_t, Int_t, Double_t, Double_t, Double_t, Double_t)
 Begin the Cell Array painting
void CellArrayFill(Int_t, Int_t, Int_t)
 Paint the Cell Array
void CellArrayEnd()
 End the Cell Array painting
void DrawPS(Int_t, Float_t *, Float_t *)
 Not needed in SVG case
Int_t CMtoSVG(Double_t u)
{return Int_t(0.5 + 72*u/2.54);}
void SetLineScale(Float_t =3)
{ }
