Copy-protected PDF File

April 23, 2006 on 4:15 pm | In 電腦應用 | No Comments

Sometimes one may want to extract text from a pdf file for further editing. This cannot be done if the pdf file is protected against copying/extracting. There are, however, 2 ways to bypass this restriction :

(1) send the pdf file as an attachment to one’s Gmail account – Gmail provides an option to view the file as HTML and text can be extracted from there (I learn this trick from here);

<meta content="OpenOffice.org 2.0 (Linux)" name="GENERATOR" /><meta content="chan" name="AUTHOR" /><meta content="20060520;9561300" name="CREATED" /><meta content="16010101;0" name="CHANGED" /><br /> <style type="text/css">  </style> <p>(2) open the pdf file with <a href="http://www.gnome.org/projects/evince">Evince</a> which is a document viewer running on Linux.</p> <p>The above work for pdf files containing Chinese text. Print-protected restriction can also be bypassed this way. But this will not work for those pdf files which need a password to open.</p> <p><em><font color="magenta">Updated on 20 May 2006<br /> </font></em></p> <div class="feedback"></div>  </div> <h2
