11 | ||
12 | A wxSVGFileDC is a device context onto which graphics and text can be | |
13 | drawn, and the output produced as a vector file, in SVG format (see the W3C | |
14 | SVG Specifications <http://www.w3.org/TR/2001/REC-SVG-20010904/>). This | |
15 | format can be read by a range of programs, including a Netscape plugin | |
16 | (Adobe), full details are given in the SVG Implementation and Resource | |
17 | Directory <http://www.svgi.org/>. Vector formats may often be smaller than | |
18 | raster formats. | |
19 | ||
20 | The intention behind wxSVGFileDC is that it can be used to produce a file | |
21 | corresponding to the screen display context, wxSVGFileDC, by passing the | |
22 | wxSVGFileDC as a parameter instead of a wxSVGFileDC. Thus the wxSVGFileDC | |
23 | is a write-only class. | |
24 | ||
25 | As the wxSVGFileDC is a vector format, raster operations like GetPixel() | |
26 | are unlikely to be supported. However, the SVG specification allows for PNG | |
27 | format raster files to be embedded in the SVG, and so bitmaps, icons and | |
28 | blit operations in wxSVGFileDC are supported. | |
29 | ||
30 | A more substantial SVG library (for reading and writing) is available at | |
31 | the wxArt2D website <http://wxart2d.sourceforge.net/>. | |
