43\brief Interface to SVG
44
45[SVG](http://www.w3.org/Graphics/SVG/Overview.htm8)
46(Scalable Vector Graphics) is a language for describing
47two-dimensional graphics in XML. SVG allows high quality vector graphics in
48HTML pages.
49
50To print a ROOT canvas "c1" into an SVG file simply do:
51~~~ {.cpp}
52 c1->Print("c1.svg");
53~~~
54The result is the ASCII file `c1.svg`.
55
56It can be open directly using a web browser or included in a html document
57the following way:
58~~~ {.cpp}
59<embed width="95%" height="500" src="c1.svg">
60~~~
61It is best viewed with Internet Explorer and you need the
62[Adobe SVG Viewer](http://www.adobe.com/svg/viewer/install/main.html)
63
64To zoom using the Adobe SVG Viewer, position the mouse over
65the area you want to zoom and click the right button.
66
67To define the zoom area,
68use Control+drag to mark the boundaries of the zoom area.
69
70To pan, use Alt+drag.
71By clicking with the right mouse button on the SVG graphics you will get
72a pop-up menu giving other ways to interact with the image.
73
74SVG files can be used directly in compressed mode to minimize the time
75transfer over the network. Compressed SVG files should be created using
76`gzip` on a normal ASCII SVG file and should then be renamed
77using the file extension `.svgz`.
