@class wxSVGFileDC
|
|
|
|
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/>.
