wxSVGFileDC
A wxSVGFileDC is a device context onto which graphics and text can be drawn, and the output produced as a vector file, in the SVG format (see
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 at
http://www.w3.org/Graphics/SVG/SVG-Implementations.htm8 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 into the wxSVGFileDC are supported.

If radius is positive, the value is assumed to be the radius of the rounded corner. If radius is negative, the absolute value is assumed to be the proportion of the smallest dimension of the rectangle. This means that the corner can be a sensible size relative to the size of the rectangle, and also avoids the strange effects X produces when the corners are too big for the rectangle. xSVGFileDC::DrawRoundedRectangle xdcdrawroundedrectangle b rowse00030 K wxSVGFileDC DrawRoundedRectangle E nableButton(\"Up\");ChangeButtonBinding(\"Up\K DrawRoundedRectangle w w $#+K! wxSVGFileDC::DrawSpline void DrawSpline(wxList *points)K Draws a spline between all given control points, using the current pen.

Note that in X, text drawing isn't handled consistently with the mapping mode; a font is always specified in point size. However, setting the user scale (see wxSVGFileDC::SetUserScale) scales the text appropriately. In Windows, scaleable TrueType fonts are always used; in X, results depend on availability of fonts, but usually a reasonable match is found. Note that the coordinate origin should ideally be selectable, but for now is always at the top left of the screen/printer. Drawing to a Windows printer device context under UNIX uses the current mapping mode, but mapping mode is currently ignored for PostScript output. The mapping mode can be one of the following: wxMM_TWIPS Each logical unit is 1/20 of a point, or 1/1440 of an inch. wxMM_POINTS wxMM_METRIC Each logical unit is a point, or 1/72 of an inch. Each logical unit is 1 mm. wxMM_LOMETRIC Each logical unit is 1/10 of a mm. wxMM_TEXT Each logical unit is 1 pixel. xSVGFileDC::SetMapMode xdcsetmapmode b rowse00072 K wxSVGFileDC SetMapMode E nableButton(\"Up\");ChangeButtonBinding(\"Up\K SetMapMode w w $#+K! wxSVGFileDC::SetPen void SetPen(const wxPen& pen)K Sets the current pen for the DC.
