Converting a postscript (.ps) to a .pdf file

I overlooked the fact that the print-to-file feature of Maple produces a postscript file, rather than a .pdf file.  If your home computer can print postscript files, then you can disregard this note.  Otherwise, you can convert a postscript file to a .pdf one in Unix as follows:
  • Launch a Unix Terminal.
  • Click on the KDE icon at the bottom left corner of your KDE work environment.  A pop-up menu appears.  Click on Utilities.  A side menu pops out.  Click on Terminal.  A Unix X terminal appears (a window with a command prompt).
  • At the command prompt, type  ls <ENTER>.
  • This lists the files in the current directory.  You should see the Maple worksheet in postscript format (<filename>.ps) ; this is the output you should have just printed-to-file from Maple.
  • To convert this to  .pdf  format, simply type at the command prompt the following command:
 ps2pdf  <filename>.ps
  • The output of the above command is a .pdf file, with file name  <filename>.pdf.   You may use the  ls  command to list files again to confirm that the .pdf file is now indeed there.  E-mail this .pdf file to yourself for printing at home.


Printing Maple worksheets while working at home

The easiest way to do it should be:
  • Print your Maple worksheet to a pdf file.
  • Click on File in the top menu bar.  The Print pop-up window appears.
  • Check the Print to File box.  Click on Print.
  • Enter a name for your Maple worksheet.  Choose the directory you want it saved to.  Click OK.
  • E-mail that resulting pdf file to yourself as an e-mail attachment.
  • Click on the icon with the globe and an evelope in the bottom menu bar of your KDE work environment.  It should be self-explanatory from there.
  • Open your e-mail and retrieve the attached pdf copy of Maple worksheet.  View it and print it locally using any standard software.


Setting up remote access to your math account on your personal computer.

PC (Windows) Users:
  • Download NX Client for Windows from the following website:
http://www.nomachine.com/download-client-windows.php
  • Install NX Client for Windows.  Launch it.
  • In the NX Client Pop-up, for host, enter math.utexas.edu
  • For port, enter 22.
  • Then, enter your login name and password of your mathematics account.
  • Click on the Login button.
  • A simulated Unix window should appear.

Mac OS X Users:
  • Download NX Client for Mac OS X from the following website:
http://www.nomachine.com/download-client-macosx.php

http://www.apple.com/downloads/macosx/apple/macosx_updates/x11formacosx.html#
  • If you use Mac OS X 10.4 or higher, locate X11 Version 1.1 on your OS X Tiger Installation CD or DVD.
  • Install both X11 and NX Client for Mac OS X.  Launch NX Client.  (NX Client will in turn lauch X11 automatically.)
