A wxSVGFileDC is a @e device context onto which graphics and text can be drawn,
and the output

(see W3C specifications).
This format can be read by a range of programs, including a Netscape plugin

in the SVG Implementation and Resource Directory.
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

bitmaps, icons and blit operations into the wxSVGFileDC are supported.

A more substantial SVG library (for reading and writing) is available at the
