TSVG Class Reference

Interface to SVG.

SVG (Scalable Vector Graphics) is a language for describing two-dimensional graphics in XML. SVG allows high quality vector graphics in HTML pages.

To print a ROOT canvas "c1" into an SVG file simply do:

c1->Print("c1.svg");

The result is the ASCII file c1.svg.

It can be open directly using a web browser or included in a html document the following way:

<embed width="95%" height="500" src="c1.svg">

It is best viewed with Internet Explorer and you need the Adobe SVG Viewer

To zoom using the Adobe SVG Viewer, position the mouse over the area you want to zoom and click the right button.

To define the zoom area, use Control+drag to mark the boundaries of the zoom area.

To pan, use Alt+drag. By clicking with the right mouse button on the SVG graphics you will get a pop-up menu giving other ways to interact with the image.

SVG files can be used directly in compressed mode to minimize the time transfer over the network. Compressed SVG files should be created using gzip on a normal ASCII SVG file and should then be renamed using the file extension .svgz.

Constructor & Destructor Documentation

◆ TSVG() [1/2]

TSVG::TSVG ( )

Default SVG constructor.

Definition at line 77 of file TSVG.cxx.

◆ TSVG() [2/2]

TSVG::TSVG ( const char *  fname,
Int_t  wtype = -113 
)

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).

Definition at line 99 of file TSVG.cxx.

◆ ~TSVG()

TSVG::~TSVG ( )
virtual

Default SVG destructor.

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.
