Class BrainWave.PostScript

java.lang.Object
   |
   +----BrainWave.PostScript
public class PostScript
extends Object
A static class that produces Strings of PostScript interpretable text.
Version:
0.9.1
This revision fixes a bug for encapsulated PostScript AND changes EPS so that there is no "scaling" to an A4 page.

0.9
Provides a system for generating PostScript from java.awt.Graphics style methods. Calling these static methods returns a String containing the PostScript required to display that graphics primitive. By concatenating a series of these strings for different graphics routines, objects drawn on the screen may be converted to PostScript.

                               int sl)
Pre-amble information for a minimally conforming PostScript document. Specifies type of PostScript (encapsulated or note) and orientation (landscape or not).
o preAmble 
 public static String preAmble(boolean encap,
                               boolean landscape)
Provided for compatibility with previous versions - no paper size is selected.
o preAmble 
 public static String preAmble(boolean encap)
Provided for compatibility with previous versions - orienation is assumed to be portrait.
o postAmble 
 public static String postAmble(boolean encap)
Trailing information to complete a PostScript document.
o drawString 
 public static String drawString(String str,
                                 int x,
                                 int y)
write the String str to the PostScript page. Precondition: str contains no newlines.
o drawString 
 public static String drawString(String str,
                                 String x,
                                 String y)
write String str to PostScript page. Precondition: str contains no newlines, and x and y are PostScript commands that evaluate to a single numeric value
o whichFont 
 public static String whichFont(Font fnt)
Return a PostScript font name for fnt. If fnt is TimesRoman, Courier, Helvetica, or Symbol, this is the corresponding font. Any other font is returned as Courier.
