\section{\class{wxSVGFileDC}}\label{wxSVGFileDC}
A wxSVGFileDC is a {\it 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.
A more substantial SVG library (for reading and writing) is available at
http://www.xs4all.nl/~kholwerd/wxstuff/canvas/htmldocbook/aap.html

Draws an arc of a circle, centred on ({\it xc, yc}), with starting point ({\it x1, y1})
and ending at ({\it x2, y2}). The current pen is used for the outline
and the current brush for filling the shape.
The arc is drawn in an anticlockwise direction from the start point to the end point.

\func{void}{DrawBitmap}{\param{const wxBitmap\&}{ bitmap}, \param{wxCoord}{ x}, \param{wxCoord}{ y}, \param{bool}{ transparent}}
Draw a bitmap on the device context at the specified point. If {\it transparent} is true and the bitmap has
a transparency mask, the bitmap will be drawn transparently.
When drawing a mono-bitmap, the current text foreground colour will be used to draw the foreground
of the bitmap (all bits set to 1), and the current text background colour to draw the background
(all bits set to 0). See also \helpref{SetTextForeground}{wxdcsettextforeground},

the current brush is used for drawing the pie.
{\it x} and {\it y} specify the x and y coordinates of the upper-left corner of the rectangle that contains
the ellipse.
{\it width} and {\it height} specify the width and height of the rectangle that contains
the ellipse.
{\it start} and {\it end} specify the start and end of the arc relative to the three-o'clock
position from the center of the rectangle. Angles are specified
in degrees (360 is a complete circle). Positive values mean
counter-clockwise motion. If {\it start} is equal to {\it end}, a
complete ellipse will be drawn.
\membersection{wxSVGFileDC::DrawIcon}\label{wxdcdrawicon}
\func{void}{DrawIcon}{\param{const wxIcon\&}{ icon}, \param{wxCoord}{ x}, \param{wxCoord}{ y}}
Draw an icon on the display (does nothing if the device context is PostScript).
This can be the simplest way of drawing bitmaps on a window.
\membersection{wxSVGFileDC::DrawLine}\label{wxdcdrawline}
\func{void}{DrawLine}{\param{wxCoord}{ x1}, \param{wxCoord}{ y1}, \param{wxCoord}{ x2}, \param{wxCoord}{ y2}}
Draws a line from the first point to the second. The current pen is used
for drawing the line.
\membersection{wxSVGFileDC::DrawLines}\label{wxdcdrawlines}
\func{void}{DrawLines}{\param{int}{ n}, \param{wxPoint}{ points[]}, \param{wxCoord}{ xoffset = 0}, \param{wxCoord}{ yoffset = 0}}
\func{void}{DrawLines}{\param{wxList *}{points}, \param{wxCoord}{ xoffset = 0}, \param{wxCoord}{ yoffset = 0}}

pointers to points, adding the optional offset coordinate. The current
pen is used for drawing the lines. The programmer is responsible for
deleting the list of points.
\membersection{wxSVGFileDC::DrawPolygon}\label{wxdcdrawpolygon}
\func{void}{DrawPolygon}{\param{int}{ n}, \param{wxPoint}{ points[]}, \param{wxCoord}{ xoffset = 0}, \param{wxCoord}{ yoffset = 0},\\
\param{int }{fill\_style = wxODDEVEN\_RULE}}
\func{void}{DrawPolygon}{\param{wxList *}{points}, \param{wxCoord}{ xoffset = 0}, \param{wxCoord}{ yoffset = 0},\\
\param{int }{fill\_style = wxODDEVEN\_RULE}}
Draws a filled polygon using an array of {\it points} of size {\it n},
or list of pointers to points, adding the optional offset coordinate.
The last argument specifies the fill rule: {\bf wxODDEVEN\_RULE} (the
default) or {\bf wxWINDING\_RULE}.
The current pen is used for drawing the outline, and the current brush
for filling the shape. Using a transparent brush suppresses filling.
The programmer is responsible for deleting the list of points.
Note that wxWindows automatically closes the first and last points.
\membersection{wxSVGFileDC::DrawPoint}\label{wxdcdrawpoint}
\func{void}{DrawPoint}{\param{wxCoord}{ x}, \param{wxCoord}{ y}}
Draws a point using the current pen.

\func{void}{DrawRotatedText}{\param{const wxString\& }{text}, \param{wxCoord}{ x}, \param{wxCoord}{ y}, \param{double}{ angle}}
Draws the text rotated by {\it angle} degrees.
The wxMSW wxDC and wxSVGFileDC rotate the text around slightly different points, depending on the size of the font
\membersection{wxSVGFileDC::DrawRoundedRectangle}\label{wxdcdrawroundedrectangle}
\func{void}{DrawRoundedRectangle}{\param{wxCoord}{ x}, \param{wxCoord}{ y}, \param{wxCoord}{ width}, \param{wxCoord}{ height}, \param{double}{ radius = 20}}
Draws a rectangle with the given top left corner, and with the given
size. The corners are quarter-circles using the given radius. The
current pen is used for the outline and the current brush for filling
the shape.
If {\it radius} is positive, the value is assumed to be the
radius of the rounded corner. If {\it radius} is negative,
the absolute value is assumed to be the {\it 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.
\membersection{wxSVGFileDC::DrawSpline}\label{wxdcdrawspline}
\func{void}{DrawSpline}{\param{wxList *}{points}}
Draws a spline between all given control points, using the current
pen. Doesn't delete the wxList and contents. The spline is drawn
using a series of lines, using an algorithm taken from the X drawing
program `XFIG'.
\func{void}{DrawSpline}{\param{wxCoord}{ x1}, \param{wxCoord}{ y1}, \param{wxCoord}{ x2}, \param{wxCoord}{ y2}, \param{wxCoord}{ x3}, \param{wxCoord}{ y3}}

\func{void}{DrawText}{\param{const wxString\& }{text}, \param{wxCoord}{ x}, \param{wxCoord}{ y}}
Draws a text string at the specified point, using the current text font,
and the current text foreground and background colours.
The coordinates refer to the top-left corner of the rectangle bounding
the string. See \helpref{wxSVGFileDC::GetTextExtent}{wxdcgettextextent} for how
to get the dimensions of a text string, which can be used to position the
text more precisely.

when drawing into a monochrome bitmap.
\membersection{wxSVGFileDC::SetFont}\label{wxdcsetfont}

\membersection{wxSVGFileDC::SetLogicalFunction}\label{wxdcsetlogicalfunction}
\func{void}{SetLogicalFunction}{\param{int}{ function}}

\membersection{wxSVGFileDC::SetMapMode}\label{wxdcsetmapmode}
\func{void}{SetMapMode}{\param{int}{ int}}
The {\it mapping mode} of the device context defines the unit of
measurement used to convert logical units to device units. 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 {\it
user scale} (see \helpref{wxSVGFileDC::SetUserScale}{wxdcsetuserscale}) 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:
\begin{twocollist}\itemsep=0pt
\twocolitem{wxMM\_TWIPS}{Each logical unit is 1/20 of a point, or 1/1440 of
an inch.}
\twocolitem{wxMM\_POINTS}{Each logical unit is a point, or 1/72 of an inch.}
\twocolitem{wxMM\_METRIC}{Each logical unit is 1 mm.}
\twocolitem{wxMM\_LOMETRIC}{Each logical unit is 1/10 of a mm.}
\twocolitem{wxMM\_TEXT}{Each logical unit is 1 pixel.}
\end{twocollist}
\membersection{wxSVGFileDC::SetPen}\label{wxdcsetpen}
\func{void}{SetPen}{\param{const wxPen\& }{pen}}
Sets the current pen for the DC.
If the argument is wxNullPen, the current pen is selected out of the device
context, and the original pen restored.
See also \helpref{wxMemoryDC}{wxmemorydc} for the interpretation of colours
when drawing into a monochrome bitmap.
\membersection{wxSVGFileDC::SetTextBackground}\label{wxdcsettextbackground}
\func{void}{SetTextBackground}{\param{const wxColour\& }{colour}}
Sets the current text background colour for the DC.
