1\section{\class{wxSVGFileDC}}\label{wxsvgfiledc}
2
3A wxSVGFileDC is a {\it device context} onto which graphics and text can be drawn, and the output
4produced as a vector file, in the SVG format (see http://www.w3.org/TR/2001/REC-SVG-20010904/ ).
5This format can be read by a range of programs, including a Netscape plugin (Adobe), full details at
6http://www.w3.org/Graphics/SVG/SVG-Implementations.htm8 Vector formats may often be smaller
7than raster formats.
8
9The intention behind wxSVGFileDC is that it can be used to produce a file corresponding
10to the screen display context, wxSVGFileDC, by passing the wxSVGFileDC as a parameter instead of a wxSVGFileDC. Thus
11the wxSVGFileDC is a write-only class.
12
13As the wxSVGFileDC is a vector format, raster operations like GetPixel are unlikely to be supported.
14However, the SVG specification allows for PNG format raster files to be embedded in the SVG, and so
15bitmaps, icons and blit operations into the wxSVGFileDC are supported.
16
17A more substantial SVG library (for reading and writing) is available at
18http://wxart2d.sourceforge.net/

133
134Draws an arc of a circle, centred on ({\it xc, yc}), with starting point ({\it x1, y1})
135and ending at ({\it x2, y2}). The current pen is used for the outline

145a transparency mask, the bitmap will be drawn transparently.
146

227
228Draws lines using an array of {\it points} of size {\it n}, or list of
229pointers to points, adding the optional offset coordinate. The current
230pen is used for drawing the lines. The programmer is responsible for
231deleting the list of points.
232
233\membersection{wxSVGFileDC::DrawPolygon}\label{wxsvgfiledcdrawpolygon}
234
235\func{void}{DrawPolygon}{\param{int}{ n}, \param{wxPoint}{ points[]}, \param{wxCoord}{ xoffset = 0}, \param{wxCoord}{ yoffset = 0},\\

239 \param{int }{fill\_style = wxODDEVEN\_RULE}}
240
241Draws a filled polygon using an array of {\it points} of size {\it n},
242or list of pointers to points, adding the optional offset coordinate.
243
244The last argument specifies the fill rule: {\bf wxODDEVEN\_RULE} (the
245default) or {\bf wxWINDING\_RULE}.
246
247The current pen is used for drawing the outline, and the current brush
248for filling the shape. Using a transparent brush suppresses filling.
249The programmer is responsible for deleting the list of points.
250
251Note that wxWindows automatically closes the first and last points.

263
264Draws a rectangle with the given top left corner, and with the given
265size. The current pen is used for the outline and the current brush
266for filling the shape.
267
268\membersection{wxSVGFileDC::DrawRotatedText}\label{wxsvgfiledcdrawrotatedtext}
269
270\func{void}{DrawRotatedText}{\param{const wxString\& }{text}, \param{wxCoord}{ x}, \param{wxCoord}{ y}, \param{double}{ angle}}
271
272Draws the text rotated by {\it angle} degrees.
273
274The wxMSW wxDC and wxSVGFileDC rotate the text around slightly different points, depending on the size of the font
275
276\membersection{wxSVGFileDC::DrawRoundedRectangle}\label{wxsvgfiledcdrawroundedrectangle}
277
278\func{void}{DrawRoundedRectangle}{\param{wxCoord}{ x}, \param{wxCoord}{ y}, \param{wxCoord}{ width}, \param{wxCoord}{ height}, \param{double}{ radius = 20}}
279
280Draws a rectangle with the given top left corner, and with the given
281size. The corners are quarter-circles using the given radius. The
282current pen is used for the outline and the current brush for filling
283the shape.
284
285If {\it radius} is positive, the value is assumed to be the
286radius of the rounded corner. If {\it radius} is negative,
287the absolute value is assumed to be the {\it proportion} of the smallest
288dimension of the rectangle. This means that the corner can be
289a sensible size relative to the size of the rectangle, and also avoids
290the strange effects X produces when the corners are too big for
291the rectangle.

293\membersection{wxSVGFileDC::DrawSpline}\label{wxsvgfiledcdrawspline}
294
295\func{void}{DrawSpline}{\param{wxList *}{points}}
296
297Draws a spline between all given control points, using the current
298pen. Doesn't delete the wxList and contents. The spline is drawn
299using a series of lines, using an algorithm taken from the X drawing
300program `XFIG'.
301
302\func{void}{DrawSpline}{\param{wxCoord}{ x1}, \param{wxCoord}{ y1}, \param{wxCoord}{ x2}, \param{wxCoord}{ y2}, \param{wxCoord}{ x3}, \param{wxCoord}{ y3}}

308\func{void}{DrawText}{\param{const wxString\& }{text}, \param{wxCoord}{ x}, \param{wxCoord}{ y}}
309
310Draws a text string at the specified point, using the current text font,
311and the current text foreground and background colours.
312
313The coordinates refer to the top-left corner of the rectangle bounding
314the string. See \helpref{wxSVGFileDC::GetTextExtent}{wxdcgettextextent} for how
315to get the dimensions of a text string, which can be used to position the

444\rtfsp{\it string} is the text string to measure, {\it w} and {\it h} are

449
450The optional parameter {\it font} specifies an alternative
451to the currently selected font: but note that this does not
452yet work under Windows, so you need to set a font for

548
549Sets the x and y axis orientation (i.e., the direction from lowest to
550highest values on the axis). The default orientation is the natural
551orientation, e.g. x axis from left to right and y axis from bottom up.
552

555\docparam{xLeftRight}{True to set the x axis orientation to the natural

564
565Sets the device origin (i.e., the origin in pixels after scaling has been
566applied).

606
607Sets the current brush for the DC.
608
609If the argument is wxNullBrush, the current brush is selected out of the device
610context, and the original brush restored, allowing the current brush to
611be destroyed safely.

635
636\func{void}{SetMapMode}{\param{int}{ int}}
637
638The {\it mapping mode} of the device context defines the unit of
639measurement used to convert logical units to device units. Note that
640in X, text drawing isn't handled consistently with the mapping mode; a
641font is always specified in point size. However, setting the {\it
642user scale} (see \helpref{wxSVGFileDC::SetUserScale}{wxdcsetuserscale}) scales the text appropriately. In
643Windows, scaleable TrueType fonts are always used; in X, results depend
644on availability of fonts, but usually a reasonable match is found.
645
646Note that the coordinate origin should ideally be selectable, but for
647now is always at the top left of the screen/printer.
648
649Drawing to a Windows printer device context under UNIX
650uses the current mapping mode, but mapping mode is currently ignored for
651PostScript output.
652
653The mapping mode can be one of the following:
654
655\begin{twocollist}\itemsep=0pt
656\twocolitem{wxMM\_TWIPS}{Each logical unit is 1/20 of a point, or 1/1440 of
657 an inch.}
658\twocolitem{wxMM\_POINTS}{Each logical unit is a point, or 1/72 of an inch.}
659\twocolitem{wxMM\_METRIC}{Each logical unit is 1 mm.}
660\twocolitem{wxMM\_LOMETRIC}{Each logical unit is 1/10 of a mm.}
661\twocolitem{wxMM\_TEXT}{Each logical unit is 1 pixel.}
