Controlling Powerpoint using Leap motion and Python

问题

I just started up with python.I lately got a project where I have to make a powerpoint slideshow.This has to be done using leap motion sdk and python.So my powerpoint will be gesture based.

1. How do I deploy this on my desktop in such a away that I just need to click on my desktop app or the ppt file itself, I get started with the powerpoint like on windows.
2. I need to detect the finger gestures using python and integrate it to next - previous functionality.

Can I get some guidance on powerpoint with PPT?

I have got the API,Documentation,SDK and I am learning python too.

The pywin32 library has a win32com.client module that lets you use COM API to control PowerPoint.

For example, this code will add a slide with an oval in it:

import win32com.client

Application = win32com.client.Dispatch("PowerPoint.Application")
Presentation = Application.Presentations.Add()
Base = Presentation.Slides.Add(1, 12)
oval = Base.Shapes.AddShape(9, 100, 100, 100, 100)

This IPython notebook has step-by-step examples on how to create a PowerPoint presentation, add objects to it, and make those objects interact in PowerPoint.

While this will allow you to use PowerPoint as an output interface, you need a different mechanism for sending messages back from PowerPoint to Python. One way is to set up a Macro that runs on a click event that interacts with a COM server set up in Python.

The documentation for this is not fantastic. However, using win32com and the PowerPoint API, you should be able to accomplish what you want to do.

The relevant commands are:

import win32com.client
import time

app = win32com.client.Dispatch("PowerPoint.Application")
presentation = app.Presentations.Open(FileName=u'C:\\path\\to\\mypresenation.pptx', ReadOnly=1)

presentation.SlideShowSettings.Run()

time.sleep(1)
presentation.SlideShowWindow.View.Next()
time.sleep(1)
presentation.SlideShowWindow.View.Next()
time.sleep(1)
presentation.SlideShowWindow.View.Previous()
time.sleep(1)

presentation.SlideShowWindow.View.Exit()

app.Quit()

Once you have a reference to the presentation, you can use this inside the code/functions where you handle the gestures.

you can some some pointers on what you want to do from this guy https://github.com/sanand0 look at his https://github.com/sanand0/pptx-git repo you should definitely get some pointers.

Hope this helps
