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");
return c1
Definition legend1.C:41

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">
include TDocParser_001 C image html pict1_TDocParser_001 png width

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.

◆ 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).
