35\section{\class{wxSVGFileDC}}\label{wxSVGFileDC}
36
37A wxSVGFileDC is a {\it device context} onto which graphics and text can be drawn, and the output
38produced as a vector file, in the SVG format (see http://www.w3.org/TR/2001/REC-SVG-20010904/ ).
39This format can be read by a range of programs, including a Netscape plugin (Adobe), full details at
40http://www.w3.org/Graphics/SVG/SVG-Implementations.htm8 Vector formats may often be smaller
41than raster formats.
42
43The intention behind wxSVGFileDC is that it can be used to produce a file corresponding
44to the screen display context, wxSVGFileDC, by passing the wxSVGFileDC as a parameter instead of a wxSVGFileDC. Thus
45the wxSVGFileDC is a write-only class.
46
47As the wxSVGFileDC is a vector format, raster operations like GetPixel are unlikely to be supported.
48However, the SVG specification allows for PNG format raster files to be embedded in the SVG, and so
49bitmaps, icons and blit operations into the wxSVGFileDC are supported.
50
51A more substantial SVG library (for reading and writing) is available at
52http://www.xs4all.nl/~kholwerd/wxstuff/canvas/htmldocbook/aap.html

161
162Draws an arc of a circle, centred on ({\it xc, yc}), with starting point ({\it x1, y1})
163and ending at ({\it x2, y2}). The current pen is used for the outline
164and the current brush for filling the shape.

ea76a6a5 172Draw a bitmap on the device context at the specified point. If {\it transparent} is true and the bitmap has
164e084a
CE
173a transparency mask, the bitmap will be drawn transparently.
174
175When drawing a mono-bitmap, the current text foreground colour will be used to draw the foreground
176of the bitmap (all bits set to 1), and the current text background colour to draw the background
177(all bits set to 0). See also \helpref{SetTextForeground}{wxdcsettextforeground},

220
221Draws an arc of an ellipse. The current pen is used for drawing the arc and
222the current brush is used for drawing the pie.
223
224{\it x} and {\it y} specify the x and y coordinates of the upper-left corner of the rectangle that contains
225the ellipse.
226
227{\it width} and {\it height} specify the width and height of the rectangle that contains
228the ellipse.
229
230{\it start} and {\it end} specify the start and end of the arc relative to the three-o'clock
231position from the center of the rectangle. Angles are specified
232in degrees (360 is a complete circle). Positive values mean
233counter-clockwise motion. If {\it start} is equal to {\it end}, a
234complete ellipse will be drawn.

253
254\func{void}{DrawLines}{\param{wxList *}{points}, \param{wxCoord}{ xoffset = 0}, \param{wxCoord}{ yoffset = 0}}
255
256Draws lines using an array of {\it points} of size {\it n}, or list of
257pointers to points, adding the optional offset coordinate. The current
258pen is used for drawing the lines. The programmer is responsible for
259deleting the list of points.
260
261\membersection{wxSVGFileDC::DrawPolygon}\label{wxdcdrawpolygon}
262
263\func{void}{DrawPolygon}{\param{int}{ n}, \param{wxPoint}{ points[]}, \param{wxCoord}{ xoffset = 0}, \param{wxCoord}{ yoffset = 0},\\

267 \param{int }{fill\_style = wxODDEVEN\_RULE}}
268
269Draws a filled polygon using an array of {\it points} of size {\it n},
270or list of pointers to points, adding the optional offset coordinate.
271
272The last argument specifies the fill rule: {\bf wxODDEVEN\_RULE} (the
273default) or {\bf wxWINDING\_RULE}.
274
275The current pen is used for drawing the outline, and the current brush
276for filling the shape. Using a transparent brush suppresses filling.
277The programmer is responsible for deleting the list of points.
278
279Note that wxWindows automatically closes the first and last points.

289
290\func{void}{DrawRectangle}{\param{wxCoord}{ x}, \param{wxCoord}{ y}, \param{wxCoord}{ width}, \param{wxCoord}{ height}}
291
292Draws a rectangle with the given top left corner, and with the given
293size. The current pen is used for the outline and the current brush
294for filling the shape.
295
296\membersection{wxSVGFileDC::DrawRotatedText}\label{wxdcdrawrotatedtext}
297
298\func{void}{DrawRotatedText}{\param{const wxString\& }{text}, \param{wxCoord}{ x}, \param{wxCoord}{ y}, \param{double}{ angle}}
299
300Draws the text rotated by {\it angle} degrees.
301
302The wxMSW wxDC and wxSVGFileDC rotate the text around slightly different points, depending on the size of the font
303
304\membersection{wxSVGFileDC::DrawRoundedRectangle}\label{wxdcdrawroundedrectangle}
305
306\func{void}{DrawRoundedRectangle}{\param{wxCoord}{ x}, \param{wxCoord}{ y}, \param{wxCoord}{ width}, \param{wxCoord}{ height}, \param{double}{ radius = 20}}
307
308Draws a rectangle with the given top left corner, and with the given
309size. The corners are quarter-circles using the given radius. The
310current pen is used for the outline and the current brush for filling
311the shape.
312
313If {\it radius} is positive, the value is assumed to be the
314radius of the rounded corner. If {\it radius} is negative,
315the absolute value is assumed to be the {\it proportion} of the smallest
316dimension of the rectangle. This means that the corner can be
317a sensible size relative to the size of the rectangle, and also avoids
318the strange effects X produces when the corners are too big for
319the rectangle.
320
321\membersection{wxSVGFileDC::DrawSpline}\label{wxdcdrawspline}
322
323\func{void}{DrawSpline}{\param{wxList *}{points}}
324
325Draws a spline between all given control points, using the current
326pen. Doesn't delete the wxList and contents. The spline is drawn
327using a series of lines, using an algorithm taken from the X drawing
328program `XFIG'.
329
330\func{void}{DrawSpline}{\param{wxCoord}{ x1}, \param{wxCoord}{ y1}, \param{wxCoord}{ x2}, \param{wxCoord}{ y2}, \param{wxCoord}{ x3}, \param{wxCoord}{ y3}}

337
338Draws a text string at the specified point, using the current text font,
339and the current text foreground and background colours.
340
341The coordinates refer to the top-left corner of the rectangle bounding
342the string. See \helpref{wxSVGFileDC::GetTextExtent}{wxdcgettextextent} for how
343to get the dimensions of a text string, which can be used to position the

635Sets the current brush for the DC.

638context, and the original brush restored, allowing the current brush to
639be destroyed safely.

664\func{void}{SetMapMode}{\param{int}{ int}}
665
666The {\it mapping mode} of the device context defines the unit of
667measurement used to convert logical units to device units. Note that
668in X, text drawing isn't handled consistently with the mapping mode; a
669font is always specified in point size. However, setting the {\it
670user scale} (see \helpref{wxSVGFileDC::SetUserScale}{wxdcsetuserscale}) scales the text appropriately. In
671Windows, scaleable TrueType fonts are always used; in X, results depend
672on availability of fonts, but usually a reasonable match is found.
673
674Note that the coordinate origin should ideally be selectable, but for
675now is always at the top left of the screen/printer.
676
677Drawing to a Windows printer device context under UNIX
678uses the current mapping mode, but mapping mode is currently ignored for
679PostScript output.
680
681The mapping mode can be one of the following:
682
683\begin{twocollist}\itemsep=0pt
684\twocolitem{wxMM\_TWIPS}{Each logical unit is 1/20 of a point, or 1/1440 of
685 an inch.}
686\twocolitem{wxMM\_POINTS}{Each logical unit is a point, or 1/72 of an inch.}
687\twocolitem{wxMM\_METRIC}{Each logical unit is 1 mm.}
688\twocolitem{wxMM\_LOMETRIC}{Each logical unit is 1/10 of a mm.}
