<center><h2>TPostScript: Graphics interface to PostScript</h2></center>
This code was initially developed in the context of HIGZ and PAW
by Olivier Couet and Pierre Juillot. It has been converted to a C++ class by
Rene Brun.

<P>To generate a Postscript (or encapsulated ps) file corresponding to
a single image in a canvas, you can:

<UL>
<LI>Select the <B>Print PostScript</B> item in the canvas <B>File</B> menu.
By default, a Postscript file with the name of the canvas.ps is generated.

<br>
<LI>Click in the canvas area, near the edges, with the right mouse button
and select the <B>Print</B> item. You can select the name of the Postscript
file. If the file name is xxx.ps, you will generate a Postscript file named
xxx.ps. If the file name is xxx.eps, you generate an encapsulated Postscript
file instead.
<br>

<LI>In your program (or macro), you can type:

<P><TT><B>
c1-&gt;Print(&quot;xxx.ps&quot;)</B> or <B>c1-&gt;Print(&quot;xxx.eps&quot;)
</B></TT>

<P>This will generate a file corresponding to the picture in the canvas
pointed by <tt><B>c1</B></tt>.

<P><TT><B>pad1-&gt;Print(&quot;xxx.ps&quot;)</B></TT>

<P>prints only the picture in the pad pointed by <tt><B>pad1</B></tt>. The size
of the Postscript picture, by default, is computed to keep the aspect ratio
of the picture on the screen, where the size along x is always 20cm. You
can set the size of the PostScript picture before generating the picture
with a command such as:

<PRE>
   TPostScript myps(&quot;myfile.ps&quot;,111)
   myps.Range(xsize,ysize);
   object-&gt;Draw();
   myps.Close();
</PRE>

<P>You can set the default paper size with:
<PRE>
   gStyle-&gt;SetPaperSize(xsize,ysize);
</PRE>
<P>You can resume writing again in this file with <tt><B>myps.Open();</B></tt>.
Note that you may have several Postscript files opened simultaneously.
</UL>

<H2>Output type</H2>

The output type allows to define how the PostScript output will looks like.
It allows to define the page format (A4, Legal etc..), the orientation
(Portrait, Landscape) and the number of images (zones) per page.
The output type has the following form:
<pre>
                        [Format][Nx][Ny][Type]
</pre>
Where:
<ul>
   <li> Format : Is an integer between 0 and 99 defining the page format.
        Example:
   <br> Format = 3 the paper is in the standard A3 format.
   <br> Format = n (1<n<98) is an An format.
   <br> Format = 4 and Format=0 are the same and define an A4 page.
   <br> The A0 format is selected by Format=99.
   <br> The US format Letter is selected by Format = 100.
   <br> The US format Legal is selected by Format = 200.
   <br> The US format Ledger is selected by Format = 300.

   <li> Nx, Ny : Specify respectively the number of zones on the x and y axis.
   Nx and Ny are integers between 1 and 9.

   <li> Type : Can be equal to:
   <ul>
   <li> 1 : Portrait mode with a small margin at the bottom of the page.
   <li> 2 : Landscape mode with a small margin at the bottom of the page.
   <li> 4 : Portrait mode with a large margin at the bottom of the page.
   <li> 5 : Landscape mode with a large margin at the bottom of the page.
            The large margin is useful for some PostScript printers (very often
            for the colour printers) as they need more space to grip the paper
            for mechanical reasons. Note that some PostScript colour printers
            can also use the so called special A4 format permitting the full
            usage of the A4 area; in this case larger margins are not necessary
            and Type=1 or 2 can be used.
   <li> 3 : Encapsulated PostScript. This Type permits the generation of files
            which can be included in other documents, for example in LaTeX
            files.
   </ul>
</ul>

<H2>Making several pictures in the same Postscript file: case 1</H2>
<P>The following macro is an example illustrating how to open a Postscript
file and draw several pictures. The generation of a new Postscript page
is automatic when <tt><B>TCanvas::Clear</B></tt> is called by
<tt><b>object-&gt;Draw()</b></tt>.
<PRE>
{
   TFile f(&quot;hsimple.root&quot;);
   TCanvas c1(&quot;c1&quot;,&quot;canvas&quot;,800,600);

   <b>// select postscript output type</b>
   <b>// type = 111   portrait  ps</b>
   <b>// type = 112   landscape ps</b>
   <b>// type = 113   eps</b>
   Int_t type = 111;

   <b>// create a postscript file and set the paper size</b>
   TPostScript ps(&quot;test.ps&quot;,type);
   ps.Range(16,24);  //set x,y of printed page

   <b>// draw 3 histograms from file hsimple.root on separate pages</b>
   hpx-&gt;Draw();
   c1.Update();      //force drawing in a macro
   hprof-&gt;Draw();
   c1.Update();
   hpx-&gt;Draw(&quot;lego1&quot;);
   c1.Update();
   ps.Close();
}
</PRE>

<H2>Making several pictures in the same Postscript file: case 2</H2>
<P>This example shows 2 pages. The canvas is divided.
<tt><B>TPostScript::NewPage</B></tt> must be called before starting a new
picture.<tt><b>object-&gt;Draw</b></tt> does not clear the canvas in this case
because we clear only the pads and not the main canvas.
Note that <tt><b>c1-&gt;Update</b></tt> must be called at the end of the first
picture.
<PRE>
{
   TFile *f1 = new TFile("hsimple.root");
   TCanvas *c1 = new TCanvas("c1");
   TPostScript *ps = new TPostScript("file.ps",112);
   c1-&gt;Divide(2,1);
<b>// picture 1</b>
   ps-&gt;NewPage();
   c1-&gt;cd(1);
   hpx-&gt;Draw();
   c1-&gt;cd(2);
   hprof-&gt;Draw();
   c1-&gt;Update();

<b>// picture 2</b>
   ps-&gt;NewPage();
   c1-&gt;cd(1);
   hpxpy-&gt;Draw();
   c1-&gt;cd(2);
   ntuple-&gt;Draw("px");
   c1-&gt;Update();
   ps-&gt;Close();

<b>// invoke Postscript viewer</b>
   gSystem-&gt;Exec("gs file.ps");
}
</PRE>

<H2>Making several pictures in the same Postscript file: case 3</H2>
<b>This is the recommended way</b>. If the Postscript file name finishes with
"(", the file remains opened (it is not closed). If the Postscript file name
finishes with ")" and the file has been opened with "(", the file is closed.
<P>Example:
<PRE>
{
   TCanvas c1("c1");
   h1.Draw();
   c1.Print("c1.ps(");  // write canvas and keep the ps file open
   h2.Draw();
   c1.Print("c1.ps");   // canvas is added to "c1.ps"
   h3.Draw();
   c1.Print("c1.ps)");  // canvas is added to "c1.ps" and ps file is closed
}
</PRE>
The <tt>TCanvas::Print("file.ps(")</tt> mechanism is very useful, but it can
be a little inconvenient to have the action of opening/closing a file being
atomic with printing a page. Particularly if pages are being generated in some
loop one needs to detect the special cases of first and last page and then
munge the argument to Print() accordingly.
<BR>The "[" and "]" can be used instead of "(" and ")" as shown below.
<P>Example:
<PRE>
   c1.Print("file.ps[");        // No actual print, just open file.ps

   for (int i=0; i<10; ++i) {
      // fill canvas for context i
      // ...

      c1.Print("file.ps");      // Actually print canvas to the file
   }

   c1.Print("file.ps]");        // No actual print, just close the file
</PRE>

<H2>Color Model</H2>
TPostScript support two color model RGB and CMYK. CMY and CMYK models are
subtractive color models unlike RGB which is an additive. They are mainly
used for printing purposes. CMY means Cyan Magenta Yellow to convert RGB
to CMY it is enough to do: C=1-R, M=1-G and Y=1-B. CMYK has one more
component K (black). The conversion from RGB to CMYK is:
<PRE>
 Double_t Black   = TMath::Min(TMath::Min(1-Red,1-Green),1-Blue);
 Double_t Cyan    = (1-Red-Black)/(1-Black);
 Double_t Magenta = (1-Green-Black)/(1-Black);
 Double_t Yellow  = (1-Blue-Black)/(1-Black);
</PRE>
CMYK add the black component which allows to have a better quality for black
printing. PostScript support the CMYK model.
<br>
To change the color model use gStyle->SetColorModelPS(c).
<ul>
<li> c = 0 means TPostScript will use RGB color model (default)
<li> c = 1 means TPostScript will use CMYK color model
</ul>
