PowerPoint 2007 SP2，PowerShell 中的 ExportAsFixedFormat? [英] PowerPoint 2007 SP2, ExportAsFixedFormat in PowerShell?

问题描述

昨天我试图将一组 PPT 批量转换为一个朋友的 PDF，我决定看看 PowerShell，因为它已经在我的 HD 上放置了一段时间.

Yesterday I was trying to batch convert a group of PPTs into PDFs for a friend, and I decided to have a look at PowerShell, since it's been sitting on my HD for a while.

这是我想出的代码.

$p = new-object -comobject powerpoint.application

# I actually don't know why I have to set the window to visible, 
# but it doesn't work otherwise, anyway, it's not the real problem I have
$p.visible = 1 

$f = $p.presentations.open('somefile.ppt')

$f.ExportAsFixedFormat('some
ewfile.pdf', 2) 

2 用于 PDF

由于蛮力"方法不起作用(类型不匹配")，我尝试使用

Since the "brute force" method didn't work ("type mismatch") I tried to import the enum type with

$pptypepdf= [Microsoft.Office.Interop.PowerPoint.PpFixedFormatType]::PpFixedFormatTypePDF
$f.ExportAsFixedFormat('some
ewfile.pdf', $pptypepdf) 

这里奇怪的是，它仍然抛出类型不匹配"的错误......

The strange thing here is that it still throws a "type mismatch" error...

另外，SaveAs 也适用于

Also, SaveAs works fine with

$f.SaveAs('some
ewfile.pdf', 32) # 32 is for PDF

我做错了什么?

更新

• PpFixedFormatType 枚举
• ExportAsFixedFormat 方法

这是完整的错误信息

$pptypepdf= [Microsoft.Office.Interop.PowerPoint.PpFixedFormatType]::PpFixedFormatTypePDF
$f.ExportAsFixedFormat($filepath, $pptypepdf)

Exception calling "ExportAsFixedFormat" with "2" argument(s): "Type mismatch. (Exception from HRESULT: 0x80020005 (DISP_E_TYPEMISMATCH))"

推荐答案

我在 Python 中遇到了同样的问题.尝试按照 Stefan Schukat 的解决方案中所述指定 PrintRange 参数:

I've come across the same problem in Python. Try specifying PrintRange argument as said in solution by Stefan Schukat:

这是 Powerpoint 中的一个错误.它定义了[在，可选的，defaultvalue(0)] PrintRange* PrintRange" 导致生成python包装器中的PrintRange = 0".因此你会得到调用方法时出错.所以makepy没有问题.解决方法使用 PrintRange=None 调用该方法，因为 None 是一个 vali COM 对象.例如.演示文稿.ExportAsFixedFormat(pptFile+'.pdf',win32com.client.constants.ppFixedFormatTypePDF,win32com.client.constants.ppFixedFormatIntentScreen，PrintRange=None)应该可以.

This is a bug in Powerpoint. It defines "[in, optional, defaultvalue(0)] PrintRange* PrintRange" which leads to the generation of "PrintRange=0" in the python wrapper. Therefore you'll get the error when calling the method. So no problem of makepy. Workaround call the method with PrintRange=None since None is a vali COM object. E.g. presentation.ExportAsFixedFormat(pptFile+'.pdf', win32com.client.constants.ppFixedFormatTypePDF, win32com.client.constants.ppFixedFormatIntentScreen, PrintRange=None) should work.

来源:使用PowerPoint 2007的导出功能时类型不匹配

我一点也不了解 PowerShell，但我想出了一个可行的例子:

I don't know PowerShell at all but have worked out a working example:

$p.ActivePresentation.PrintOptions.Ranges.Add(1,1)
$r = $p.ActivePresentation.PrintOptions.Ranges.Item(1)
$document.ExportAsFixedFormat('D:\ps.pdf', 2, 1, 0, 1, 1, 0, $r)

这不是一个完整的解决方案，但已完成导出.它以某种方式导出完整的演示文稿，而不仅仅是幻灯片.1，和我想的一样.附言哦.这是相同的解决方案

This isn't a full solution, but exporting is done. It somehow exports full presentation, not only slide no. 1, as I thought. P.S. Oh. Here's the same solution
