在Powerpoint上是否有任何有关Python win32com操作的文档？

Question

I have gat some samples about how to open a presentation and access the slides and shapes. But I want to do some more other operations(eg generate a thumbnail from a specified slide). What methods can I use? Is there any document illustrating all the functionalities?

Answer 1

Not to discourage you, but my experience using COM from Python is that you won't find many examples.

I would be shocked (but happy to see) if anybody posted a big tutorial or reference using PowerPoint in Python. Probably the best you'll find, which you've probably already found, is this article

However, if you follow along through that article and some of the other Python+COM code around, you start to see the patterns of how VB and C# code converts to Python code using the same interfaces.

Once you understand that, your best source of information is probably the PowerPoint API reference on MSDN.

Answer 2

From looking at the samples Jeremiah pointed to, it looks like you'd start there then do something like this, assuming you wanted to export slide #42:

Slide = Presentation.Slides(42)
Slide.Export FileName, "PNG", 1024, 768

Substitute the full path\\filename.ext to the file you want to export to for Filename; string. Use PNG, JPG, GIF, WMF, EMF, TIF (not always a good idea from PowerPoint), etc; string The next two numbers are the width and height (in pixels) at which to export the image; VBLong (signed 32-bit (4-byte) numbers ranging in value from -2,147,483,648 to 2,147,483,647)

I've petted pythons but never coded in them; this is my best guess as to syntax. Shouldn't be too much of a stretch to fix any errors.
