3a7fb603 | 11 | A wxSVGFileDC is a device context onto which graphics and text can be |
e844dc64 VZ |
12 | drawn, and the output produced as a vector file, in SVG format. |
13 | ||
14 | This format can be read by a range of programs, including a Netscape plugin | |
15 | (Adobe) and the open source Inkscape program (http://inkscape.org/). Full | |
16 | details are given in the W3C SVG recommendation (http://www.w3.org/TR/SVG/). | |
7c913512 | 17 | |
23324ae1 | 18 | The intention behind wxSVGFileDC is that it can be used to produce a file |
3a7fb603 | 19 | corresponding to the screen display context, wxSVGFileDC, by passing the |
e844dc64 | 20 | wxSVGFileDC as a parameter instead of a wxDC. Thus the wxSVGFileDC |
3a7fb603 | 21 | is a write-only class. |

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

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