I have a large number of images. I want to organize them in powerpoint files by automatically insert each picture to a new powerpoint slide and control it’s position and size. I came across a nice Python library – python-pptx at https://python-pptx.readthedocs.io/en/latest/. It provides functions to automate generating PowerPoint slides. Below are some information from the website. I keep the information for future use.
python-pptx is a Python library for creating and updating PowerPoint (.pptx) files.
A typical use would be generating a customized PowerPoint presentation from database content, downloadable by clicking a link in a web application. Several developers have used it to automate production of presentation-ready engineering status reports based on information held in their work management system. It could also be used for making bulk updates to a library of presentations or simply to automate the production of a slide or two that would be tedious to get right by hand.
Chris Moffitt wrote a nice article to explain how to use the above library at http://pbpython.com/creating-powerpoint.html. He specifically talked about how to use PowerPoint templates to generate new slides.
