Constructor & Destructor Documentation

EpsDrawer	(	std::ostream &	os,
		int	x,
		int	y
	)

The generated file is put to os.

x and y determine the upper right corner of the bounding box. The lower left corner is (0,0).

EpsDrawer	(	std::ostream &	os,
		int	x1,
		int	y1,
		int	x2,
		int	y2
	)

The generated file is put to os.

(x1,y1) and (x2,y2) determine the lower left and the upper right corners of the bounding box, respectively.

EpsDrawer	(	std::ostream &	os,
		dim2::Point< double >	s
	)

The generated file is put to os.

s determines the upper right corner of the bounding box. The lower left corner is (0,0).

EpsDrawer	(	std::ostream &	os,
		dim2::Point< double >	a,
		dim2::Point< double >	b
	)

The generated file is put to os.

a and b determine the lower left and the upper right corners of the bounding box, respectively.

EpsDrawer	(	const std::string &	name,
		int	x,
		int	y
	)

The generated picture is put to the file name.

x and y determine the upper right corner of the bounding box. The lower left corner is (0,0).

EpsDrawer	(	const std::string &	name,
		int	x1,
		int	y1,
		int	x2,
		int	y2
	)

The generated picture is put to the file name.

(x1,y1) and (x2,y2) determine the lower left and the upper right corners of the bounding box, respectively.

EpsDrawer	(	const std::string &	name,
		dim2::Point< double >	s
	)

The generated picture is put to the file name.

s determines the upper right corner of the bounding box. The lower left corner is (0,0).

EpsDrawer	(	const std::string &	name,
		dim2::Point< double >	a,
		dim2::Point< double >	b
	)

The generated picture is put to the file name.

a and b determine the lower left and the upper right corners of the bounding box, respectively.

Member Function Documentation

EpsDrawer & save

(

)

This function saves the current coordinate system, and the parameters set by color(), lineWidth() etc. The can be restore()d later.

The save() - restore() pairs can be nested.

EpsDrawer & centerMode

(

bool

m

)

Sets whether text output is centerized of not.

Warning:

save() doesn't save this setting.

EpsDrawer & collect

(

)

If you call this function, then the drawing operations like line(), lineTo(), moveTo() will not take place immediately, but istead they are collected. These operations form a path. Then you can stroke(), fill(), eoFill(), clip() or eoClip() it. When drawing, you can also use closePath() to - surprise - close the current path.

This example draws a red filled diamond.

         EpsDraw ed("diamond.eps",-1,-1,1,1);
         ed.color(1,0,0,).collect().line(0,-1,1,0).lineTo(0,1)
           .lineTo(-1,0).closePath().fill();

EpsDrawer & stroke

(

)

Stroke (draw) a path.

See also:

collect()

EpsDrawer & fill

(

)

Fill a path.

See also:

collect()

EpsDrawer & eoFill

(

)

Even-odd fill a path.

See also:

collect()

EpsDrawer & clip

(

)

This function sets a clipping area. After that, the drawing operations will affect only this area.

See also:

collect()

EpsDrawer & eoClip

(

)

This function sets a clipping area using even-odd rule. After that, the drawing operations will affect only this area.

It can be 0, 1 or 2

EpsDrawer & lineJoin

(

int
