7.3.7 Printing the Graph
------------------------

DDD allows for printing the graph picture on PostScript printers or
into files.  This is useful for documenting program states.

   To print the graph on a PostScript printer, select `File => Print
Graph'.  Enter the printing command in the `Print Command' field.
Click on the `OK' or the `Apply' button to start printing.

   As an alternative, you may also print the graph in a file.  Click on
the `File' button and enter the file name in the `File Name' field.
Click on the `Print' button to create the file.

   When the graph is printed in a file, two formats are available:

   * `PostScript'--suitable for enclosing the graph in another document;

   * `FIG'--suitable for post-processing, using the `xfig' graphic
     editor, or for conversion into other formats (among others, IBMGL,
     TeX, PIC), using the `transfig' or `fig2dev' programs.  

   Please note the following _caveats_ related to printing graphs:

   * If any displays were selected when invoking the `Print' dialog, the
     option `Selected Only' is set.  This makes DDD print only the
     selected displays.

   * The `Color', `Orientation', and `Paper Size' options are
     meaningful for PostScript only.

   These settings are tied to the following resources:

 -- Resource: printCommand (class PrintCommand)
     The command to print a PostScript file.  Usually `lp' or `lpr'.

 -- Resource: paperSize (class PaperSize)
     The paper size used for printing, in format `WIDTH x HEIGHT'.  The
     default is ISO A4 format, or `210mm x 297mm'.
