- A wxSVGFileDC is a @e device context onto which graphics and text can be drawn,
- and the output
- produced as a vector file, in the SVG format
- (see W3C specifications).
- This format can be read by a range of programs, including a Netscape plugin
- (Adobe), full details
- in the SVG Implementation and Resource Directory.
- Vector formats may often be smaller than raster formats.
+ 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.
+ corresponding to the screen display context, wxSVGFileDC, by passing the

- 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 into the wxSVGFileDC are supported.
