Inheritance diagram for wxSVGFileDC:

Detailed Description

A wxSVGFileDC is a device context onto which graphics and text can be drawn, and the output produced as a vector file, in SVG format (see the W3C SVG Specifications <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 are given in the SVG Implementation and Resource Directory <http://www.svgi.org/>. 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 in wxSVGFileDC are supported.

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

		wxCoord	x2,
		wxCoord	y2
	)

Reimplemented from wxDC.

void wxSVGFileDC::DrawLines	(	int	n,
		wxPoint	points[],
		wxCoord	xoffset = `0`,
		wxCoord	yoffset = `0`
	)

	)

		wxCoord	xoffset = `0`,
		wxCoord	yoffset = `0`,
		int	fill_style = `wxODDEVEN_RULE`
	)

Draws a filled polygon using an array of points of size n, or list of pointers to points, adding the optional offset coordinate. wxWidgets automatically closes the first and last points.

The last argument specifies the fill rule: wxODDEVEN_RULE (the default) or 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.

Reimplemented from wxDC.

void wxSVGFileDC::DrawPolygon	(	wxList *	points,
		wxCoord	xoffset = `0`,
		wxCoord	yoffset = `0`,
		int	fill_style = `wxODDEVEN_RULE`
	)

Draws a filled polygon using an array of points of size n, or list of pointers to points, adding the optional offset coordinate. wxWidgets automatically closes the first and last points.

The last argument specifies the fill rule: wxODDEVEN_RULE (the default) or 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.

void wxSVGFileDC::DrawRectangle	(	wxCoord	x,
		wxCoord	y,
		wxCoord	width,
		wxCoord	height
	)

Reimplemented from wxDC.

void wxSVGFileDC::DrawRotatedText	(	const wxString &	text,
		wxCoord	x,
		wxCoord	y,
		double	angle
	)

Draws the text rotated by angle degrees.

The wxMSW wxDC and wxSVGFileDC rotate the text around slightly different points, depending on the size of the font.

Reimplemented from wxDC.

void wxSVGFileDC::DrawRoundedRectangle	(	wxCoord	x,
		wxCoord	y,
		wxCoord	width,
		wxCoord	height,
		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 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.

Reimplemented from wxDC.

void wxSVGFileDC::DrawSpline ( const wxPointList * points )

See also:: wxFont

Reimplemented from wxDC.

void wxSVGFileDC::SetLogicalFunction ( int function )

Does the same as wxDC::SetLogicalFunction(), except that only wxCOPY is avalaible. Trying to set one of the othe values will fail.

Reimplemented from wxDC.

void wxSVGFileDC::SetMapMode ( int mode )

The 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 user scale scales the text appropriately. In Windows, scalable 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 - Each logical unit is a point, or 1/72 of an inch.
wxMM_METRIC - 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.
