Constructor & Destructor Documentation

SVG::SVG	(	String_Const	base_name,
		double	width,
		double	height,
		double	x_scale,
		double	y_scale,
		String_Const	units
	)

Open an SVG object:

Parameters:

base_name	is the base name of the file name without the .svg.
width	is the width of the SVG.
height	is the height of the SVG.
x_scale	is the amount is scale in X.
y_scale	is the amount to scale in Y.
units	is the units to use.

Returns:: a new *SVG* object.

SVG__open*() will create and return a new *SVG* for writing out scable vector graphics.

Definition at line 117 of file SVG.cpp.

SVG::~SVG ( )

Close SVG object.

Parameters:

svg	object to close

SVG__close*() will close *svg*.

Member Function Documentation

void SVG::cartesian_scale	(	double	x_width,
		double	y_height,
		BoundingBox *	bounding_box
	)

Turns *svg* into a cartesian graphing canvas bounded by bounding_box*.

Parameters:

svg	is the SVG object to modify.
x_width	is the available width graph on.
y_height	is the available height graph on.
bounding_box	specifies the BoundingBox of the values to be graphed.

SVG__cartesian_scale*() will modifiy *svg* so that it can graph lines, rectangles, etc, in an area bounded by *bounding_box*. The available graphing area is *x_width* by *y_height*.

Definition at line 23 of file SVG.cpp.

void SVG::line	(	double	x1,
		double	y1,
		double	x2,
		double	y2,
		String_Const	stroke
	)

Draw a line from (*x1*, *y1*) to (*x2*, *y2*) using *stroke*.

Parameters:

svg	is the SVG object to draw line to.
x1	is X coordinate of first point.
y1	is Y coordinate of first point.
x2	is X coordinate of second point.
y2	is Y coordinate of second point.
stroke	is stroke string.

SVG__line*() will draw a line to *svg* from (*x1*, *y1*) to (*x2*, *y2*) using *stroke*.

Definition at line 91 of file SVG.cpp.

void SVG::rectangle	(	double	x,
		double	y,
		double	width,
		double	height,
		String_Const	stroke_color,
		String_Const	fill_color
	)

Draw a *width* by *height* rectangle at (*x*, *y*).

Parameters:

svg	is the SVG object to draw rectangle to.
x	is the upper left X coordinate.
y	is the uppper left Y coordinate.
width	is the rectangle width.
height	is the rectangle height.
stroke_color	is the exterior line color.
fill_color	is the interior fill color.

SVG__rectangle* will draw a *width* by *height* rectangle at (*x*, *y*) with *stroke_color* and *fill_color* specifying the external line color and internal fill color respectivily.

Definition at line 171 of file SVG.cpp.

void SVG::setOffsets	(	double	x_offset,
		double	y_offset
	)

Definition at line 207 of file SVG.cpp.

void SVG::text	(	String_Const	message,
		double	x,
		double	y,
		String_Const	font_family,
		unsigned int	font_size
	)

draw *message* at (*x*, *y*).

Parameters:

svg	is the SVG object to use.
message	is the message to draw.
x	is the X coordinate to draw text at.
y	is the Y coordinate of draw text at.
font_family	is the font family to use.
font_size	is the font size.

SVG__text*() will draw *message* at (*x*, *y*) with *font_size* font of type *font_family*.
