使用Perl密碼保護的PPT文件

Question

有人能讓我知道如何在Perl中使用下面的Microsoft Presentation Object Properties嗎？

基本上我想用Password屬性來保護演示文稿。

該腳本基於來自angiehope的perlmonks文章，根據上面@FtLie的評論。我已使用Office 2010對此進行了測試。腳本將在與腳本相同的文件中創建一個名爲ppt_test.ppt的文件，並在保存的文檔上設置密碼「secret」。

use strict; 
use warnings; 
use v5.10; 

use Try::Tiny; 
use Data::Dumper; 
use Carp; 

use FindBin qw ($Bin); 

use Win32::OLE qw(in CP_UTF8); 
Win32::OLE->Option(CP => CP_UTF8); 
$Win32::OLE::Warn = 3; 
my $filename = "$Bin/ppt_test.ppt"; 
unlink $filename if (-e $filename); 

print("Starting Powerpoint Object\n"); 
my $power = Win32::OLE->GetActiveObject('Powerpoint.Application') || 
    Win32::OLE->new('Powerpoint.Application', 'Quit'); 

my $ppt = $power->Presentations->Add(); 
# 12 = blank layout 
my $slide = $ppt->Slides->Add(1,12); 
# 1 = text in horizontal direction, the next two numbers describe the position 
# and the last numbers the width and height of the box 
my $new_textbox = $slide->Shapes->AddTextbox(1,30,30,600,200); 
my $text_frame = $new_textbox->TextFrame; 
my $text_range = $text_frame->TextRange; 
$text_range->{Text} = "Please print \x{03B1},\x{03B2},\x{03B3}"; 

# Now set the password 
my $password = 'secret'; 
$ppt->{Password} = $password; 

$ppt->SaveAs($filename); 
$ppt->Close();
