CGAL::Postscript_file_stream

#include <CGAL/IO/Postscript_file_stream.h>

Definition

Creation

Postscript_file_stream PS;
	creates a postscript file stream. The name of the output file is CGAL_unnamed.ps .
Postscript_file_stream PS ( const char* filename);
	creates a postscript file stream. The name of the output file is filename .
Postscript_file_stream PS ( float w, float h);
	creates a postscript file stream that draws the output to a box of physical size width/40 $$ × height/40 cm. The name of the output file is CGAL_unnamed.ps .
Postscript_file_stream PS ( float w, float h, const char* filename);
	creates a postscript file stream that draws the output to a box of physical size width/40 $$ × height/40 cm. The name of the output file is filename .

Operations

void	PS.init ( double x0, double x1, double y0)
		initializes the part of the object space that is mapped to the physical drawing box to [x0,x1] $$ × [y0,y0 + height$$*width/(x1-x0)], where width and height are the width and the height of the drawing box in cm.

The following functions have been added to give Postscript_file_stream the same interface as Window_stream to allow easily replacement of Window_stream by Postscript_file_stream .

void	PS.display ()	does nothing
void	PS.display ( int x, int y)
		does nothing
int	PS.read_mouse ( double& x, double& y)
		returns 1
leda_color	PS.set_fg_color ( leda_color c)
		like set_color(c).

See the LEDA Manual [MNSU] for further operations on ps_file.

Output Operators

The output operator is defined for all geometric classes in the two-dimensional CGAL kernel.

Postscript_file_stream&
	Postscript_file_stream& PS << Class c
		inserts object c into the stream PS.
Postscript_file_stream&
	Postscript_file_stream& PS << Color c
		changes the foreground color for the next objects that will be inserted into PS.
void	cgalize ( Postscript_file_stream& ps)
		sets a few default values for drawing to ps. In particular, node width is set to 5 and line width to 1.

There are no input operators of course.
