How can I programmatically open and save a PowerPoint presentation as HTML/JPEG in C# or Perl?

I am looking for a code snippet that does just this, preferably in C# or even Perl.

I hope this not a big task ;)


The following will open C:\presentation1.ppt and save the slides as C:\Presentation1\slide1.jpg etc.

If you need to get the interop assembly, it is available under 'Tools' in the Office install program, or you can download it from here (office 2003). You should be able to find the links for other versions from there if you have a newer version of office.

using Microsoft.Office.Core;
using PowerPoint = Microsoft.Office.Interop.PowerPoint;

namespace PPInterop
  class Program
    static void Main(string[] args)
        var app = new PowerPoint.Application();

        var pres = app.Presentations;

        var file = pres.Open(@"C:\Presentation1.ppt", MsoTriState.msoTrue, MsoTriState.msoTrue, MsoTriState.msoFalse);

        file.SaveCopyAs(@"C:\presentation1.jpg", Microsoft.Office.Interop.PowerPoint.PpSaveAsFileType.ppSaveAsJPG, MsoTriState.msoTrue);

Edit: Sinan's version using export looks to be a bit better option since you can specify an output resolution. For C#, change the last line above to:

file.Export(@"C:\presentation1.jpg", "JPG", 1024, 768);

As Kev points out, don't use this on a web server. However, the following Perl script is perfectly fine for offline file conversion etc:


use strict;
use warnings;

use Win32::OLE;
use Win32::OLE::Const 'Microsoft PowerPoint';
$Win32::OLE::Warn = 3;

use File::Basename;
use File::Spec::Functions qw( catfile );

my $EXPORT_DIR = catfile $ENV{TEMP}, 'ppt';

my ($ppt) = @ARGV;
defined $ppt or do {
    my $progname = fileparse $0;
    warn "Usage: $progname output_filename\n";
    exit 1;

my $app = get_powerpoint();
$app->{Visible} = 1;

my $presentation = $app->Presentations->Open($ppt);
die "Could not open '$ppt'\n" unless $presentation;

    catfile( $EXPORT_DIR, basename $ppt ),

sub get_powerpoint {
    my $app;
    eval { $app = Win32::OLE->GetActiveObject('PowerPoint.Application') };
    die "$@\n" if $@;

    unless(defined $app) {
        $app = Win32::OLE->new('PowerPoint.Application',
            sub { $_[0]->Quit }
        ) or die sprintf(
            "Cannot start PowerPoint: '%s'\n", Win32::OLE->LastError
    return $app;

How do I use the new SVN merge-tracking?

svn merge merge-tracking

In my existing (Pre-SVN 1.5) merge strategy, we create a copy of the Trunk (called BasePoint) at the moment of branch-creation for referencing later during the merge.
