41\brief Interface to SVG
42
43[SVG](http://www.w3.org/Graphics/SVG/Overview.htm8)
44(Scalable Vector Graphics) is a language for describing
45two-dimensional graphics in XML. SVG allows high quality vector graphics in
46HTML pages.
47
48To print a ROOT canvas "c1" into an SVG file simply do:
49~~~ {.cpp}
50 c1->Print("c1.svg");
51~~~
52The result is the ASCII file `c1.svg`.
53
54It can be open directly using a web browser or included in a html document
55the following way:
56~~~ {.cpp}
57<embed width="95%" height="500" src="c1.svg">
58~~~
59It is best viewed with Internet Explorer and you need the
60[Adobe SVG Viewer](http://www.adobe.com/svg/viewer/install/main.html)
61
62To zoom using the Adobe SVG Viewer, position the mouse over
63the area you want to zoom and click the right button.
64
65To define the zoom area,
66use Control+drag to mark the boundaries of the zoom area.
67
68To pan, use Alt+drag.
69By clicking with the right mouse button on the SVG graphics you will get
70a pop-up menu giving other ways to interact with the image.
71
72SVG files can be used directly in compressed mode to minimize the time
73transfer over the network. Compressed SVG files should be created using
74`gzip` on a normal ASCII SVG file and should then be renamed
75using the file extension `.svgz`.
