如何在 C# 或 Perl 中以编程方式打开 PowerPoint 演示文稿并将其保存为 HTML/JPEG?

发布于 2024-07-25 07:04:01 字数 72 浏览 9 评论 0原文

我正在寻找一个可以实现此目的的代码片段,最好是用 C# 甚至 Perl 编写。

我希望这不是一项艰巨的任务;)

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

I hope this not a big task ;)

以下将打开 C:\presentation1.ppt 并将幻灯片保存为 C:\Presentation1\slide1.jpg 等。

如果您需要获取互操作程序集,则为您可以在 Office 安装程序的“工具”下找到它,也可以从 此处 (office 2003)。 如果您有较新版本的 Office,您应该能够从那里找到其他版本的链接。

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);
    }
  }
}

编辑:
Sinan 使用导出的版本 看起来是一个更好的选择,因为您可以指定输出分辨率。 对于 C#,将上面的最后一行更改为:

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

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);

作为 Kev 指出,不要在网络服务器上使用它。 然而,以下 Perl 脚本非常适合离线文件转换等:

#!/usr/bin/perl

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;

$presentation->Export(
    catfile( $EXPORT_DIR, basename $ppt ),
    'JPG',
    1024,
    768,
);

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;
}

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:

#!/usr/bin/perl

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;

$presentation->Export(
    catfile( $EXPORT_DIR, basename $ppt ),
    'JPG',
    1024,
    768,
);

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;
}
