Interface to PostScript.

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

Select the Print PostScript item in the canvas File menu. By default, a Postscript file with the name of the canvas.ps is generated.
Click in the canvas area, near the edges, with the right mouse button and select the Print 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.
In your program (or macro), you can type:
c1->Print("xxx.ps");

c1
return c1
Definition legend1.C:41

or:
c1->Print("xxx.eps");

This will generate a file corresponding to the picture in the canvas pointed by c1.
pad1->Print("xxx.ps");

prints only the picture in the pad pointed by pad1.

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:

TPostScript myps("myfile.ps",111)
myps.Range(xsize,ysize);
object->Draw();
myps.Close();

You can set the default paper size with:

gStyle->SetPaperSize(xsize,ysize);

gStyle

R__EXTERN TStyle * gStyle

Definition TStyle.h:433

TStyle::SetPaperSize

void SetPaperSize(EPaperSize size)

Set paper size for PostScript output.

Definition TStyle.cxx:1700

You can resume writing again in this file with myps.Open();. Note that you may have several Postscript files opened simultaneously.

Output type

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:

[Format][Nx][Ny][Type]

Format

static char * Format(const char *format, va_list ap)

Format a string in a circular formatting buffer (using a printf style format descriptor).

Definition TString.cxx:2420

Where:

Format : Is an integer between 0 and 99 defining the page format:
Format = 3 the paper is in the standard A3 format.

Format = n (1<n<98) is an An format.

Format = 4 and Format=0 are the same and define an A4 page.

The A0 format is selected by Format=99.

The US format Letter is selected by Format = 100.

The US format Legal is selected by Format = 200.

The US format Ledger is selected by Format = 300.

n
const Int_t n
Definition legend1.C:16
Nx, Ny : Specify respectively the number of zones on the x and y axis. Nx and Ny are integers between 1 and 9.
Type : Can be equal to:
- 1 : Portrait mode with a small margin at the bottom of the page.
- 2 : Landscape mode with a small margin at the bottom of the page.
- 4 : Portrait mode with a large margin at the bottom of the page.
- 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.
- 3 : Encapsulated PostScript. This Type permits the generation of files which can be included in other documents, for example in LaTeX files.

Making several pictures in the same Postscript file: case 1

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 TCanvas::Clear is called by object->Draw().

{
   TFile f("hsimple.root");
   TCanvas c1("c1","canvas",800,600);
 
   // select postscript output type
   // type = 111   portrait  ps
   // type = 112   landscape ps
   // type = 113   eps
   Int_t type = 111;
 
   // create a postscript file and set the paper size
   TPostScript ps("test.ps",type);
   ps.Range(16,24);  //set x,y of printed page
 
   // draw 3 histograms from file hsimple.root on separate pages
   hpx->Draw();
   c1.Update();      //force drawing in a macro
   hprof->Draw();
   c1.Update();
   hpx->Draw("lego1");
   c1.Update();
   ps.Close();
}

Making several pictures in the same Postscript file: case 2

This example shows 2 pages. The canvas is divided. TPostScript::NewPage must be called before starting a new picture.object->Draw does not clear the canvas in this case because we clear only the pads and not the main canvas. Note that c1->Update must be called at the end of the first picture.

{
   TFile *f1 = new TFile("hsimple.root");
   TCanvas *c1 = new TCanvas("c1");
   TPostScript *ps = new TPostScript("file.ps",112);
   c1->Divide(2,1);
   // picture 1
   ps->NewPage();
   c1->cd(1);
   hpx->Draw();
   c1->cd(2);
   hprof->Draw();
   c1->Update();
 
   // picture 2
   ps->NewPage();
   c1->cd(1);
   hpxpy->Draw();
   c1->cd(2);
   ntuple->Draw("px");
   c1->Update();
   ps->Close();
 
   // invoke Postscript viewer
   gSystem->Exec("gs file.ps");
}

Making several pictures in the same Postscript file: case 3

This is the recommended way. 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.

Example:

{
   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
}

The TCanvas::Print("file.ps(") 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. The "[" and "]" can be used instead of "(" and ")" as shown below.

Example:

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

Color Model

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:

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);

CMYK add the black component which allows to have a better quality for black printing. PostScript support the CMYK model.

To change the color model use gStyle->SetColorModelPS(c).

c = 0 means TPostScript will use RGB color model (default)
c = 1 means TPostScript will use CMYK color model

		Int_t	H,
		Double_t	x1,
		Double_t	x2,
		Double_t	y1,
		Double_t	y2
	)

overridevirtual

Draw a Cell Array.

Drawing a PostScript Cell Array is in fact done thanks to three procedures: CellArrayBegin, CellArrayFill, and CellArrayEnd.

CellArrayBegin: Initiate the Cell Array by writing the necessary PostScript procedures and the initial values of the required parameters. The input parameters are:
- W: number of boxes along the width.
- H: number of boxes along the height
- x1,x2,y1,y2: First box coordinates.
CellArrayFill: Is called for each box of the Cell Array. The first box is the top left one and the last box is the bottom right one. The input parameters are the Red, Green, and Blue components of the box colour. These Levels are between 0 and 255.
CellArrayEnd: Finishes the Cell Array.

PostScript cannot handle arrays larger than 65535. So the Cell Array is drawn in several pieces.

Patterns definition.

Define the pattern ipat in the current PS file. ipat can vary from 1 to 25. Together with the pattern, the color (color) in which the pattern has to be drawn is also required. A pattern is defined in the current PS file only the first time it is used. Some level 2 Postscript functions are used, so on level 1 printers, patterns will not work. This is not a big problem because patterns are defined only if they are used, so if they are not used a PS level 1 file will not be polluted by level 2 features, and in any case the old patterns used a lot of memory which made them almost unusable on old level 1 printers. Finally we should say that level 1 devices are becoming very rare. The official PostScript is now level 3 !
