Magic Folder to Convert DOC and OpenOffice to PDF

Most of the information in this post is derived from http://www.tech-faq.com/convert-word-to-pdf.html. The code’s reposted here as a service, because the code there needs some editing.

Also, a useful thread about executing OOo macros is at http://www.oooforum.org/forum/viewtopic.phtml?t=2619.

Here’s the code to automate the opening and saving of a file as PDF, using Open Office. Paste this into your standard macros.

Sub ConvertWordToPDF(cFile) 
	cURL = ConvertToURL(cFile) 
	' Open the document. 
	' Just blindly assume that the document is of a type that OOo will 
	' correctly recognize and open — without specifying an import filter. 
	oDoc = StarDesktop.loadComponentFromURL(cURL, "_blank", 0, Array(MakePropertyValue("Hidden", True), )) 
	cFile = Left(cFile, Len(cFile) - 4) + ".pdf" 
	cURL = ConvertToURL(cFile) 
	' Save the document using a filter. 
	oDoc.storeToURL(cURL, Array(MakePropertyValue("FilterName", "writer_pdf_Export"), )) 
	oDoc.close(True) 
End Sub 

Function MakePropertyValue( Optional cName As String, Optional uValue ) As com.sun.star.beans.PropertyValue 
	Dim oPropertyValue As New com.sun.star.beans.PropertyValue 
	If Not IsMissing( cName ) Then 
		oPropertyValue.Name = cName 
	EndIf 
	If Not IsMissing( uValue ) Then 
		oPropertyValue.Value = uValue 
	EndIf 
	MakePropertyValue()   = oPropertyValue 
End Function 

sub test()
	ConvertWordToPDF("file:///home/johnk/Desktop/cooking websites article.odt")
end sub	

To use this macro, you should execute it from the command line. Here’s a shell script that helps.

#!/bin/sh 
DIR=$(pwd) 
DOC=$DIR/$1 
/user/bin/oowriter-invisible "macro://Standard.Module1.ConvertWordToPDF($DOC)" 

And last but not least, my addition – a script that watches a folder called pdeffer and converts DOC files to PDF. The only problem is that only simple, textual files with graphics will work. More complex layouts will fail.

To use it, execute it in the background or start it in a “screen” session. It’s not a full-fledged service (and won’t be).

#! /usr/bin/perl

chdir '/home/johnk/pdeffer';

use Cwd;

%docs = ();
%pdfs = ();

sub main() {
  print "checking\n";
  opendir DH,'.';
  while( $file = readdir(DH) ) {
    if ($file =~ /.doc$/) {
      $docs{$file} = 1;
    }
    if ($file =~ /.pdf$/) {
      $pdfs{$file} = 1;
    }
  }
  closedir DH;

  foreach $d (keys(%docs))  {
    print "$d\n";
    $p = $d;
    $p =~ s/.doc/.pdf/;
    next if ($pdfs{$p});

    $filename = getcwd().'/'.$d;
    print "$filename\n";

    system('oowriter -invisible "macro:///Standard.Module1.ConvertWordToPDF('.$filename.')"');
  }
}

for(;;) {
  &main();
  sleep 10;
}
