## Detailed Description

A wxSVGFileDC is a device context onto which graphics and text can be drawn, and the output produced as a vector file, in SVG format (see the W3C SVG Specifications <http://www.w3.org/TR/2001/REC-SVG-20010904/>).

This format can be read by a range of programs, including a Netscape plugin (Adobe), full details are given in the SVG Implementation and Resource Directory <http://www.svgi.org/>. Vector formats may often be smaller than raster formats.

The intention behind wxSVGFileDC is that it can be used to produce a file corresponding to the screen display context, wxSVGFileDC, by passing the wxSVGFileDC as a parameter instead of a wxSVGFileDC. Thus the wxSVGFileDC is a write-only class.

As the wxSVGFileDC is a vector format, raster operations like GetPixel() are unlikely to be supported. However, the SVG specification allows for PNG format raster files to be embedded in the SVG, and so bitmaps, icons and blit operations in wxSVGFileDC are supported.

A more substantial SVG library (for reading and writing) is available at the wxArt2D website <http://wxart2d.sourceforge.net/>.
