Use python to create PowerPoint slides automatically

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.

Automate PowerPoint Slide Creation

One time I have to generate a lot of graphs on fly and insert them to PowerPoint slides to create a nice presentation. The situation is that I have to repeat this process again and again every week or days. The graphs generated on fly are a fixed set. Nobody want to do this boring work again and again. So I developed a VBA script in PowerPoint. I can use it to automate the process. Here are some pieces that are relevant to the auntomatic process.
First of all, we need insert new slide.

' create a new blank slide
ActiveWindow.View.GotoSlide Index:=ActivePresentation.Slides.Add(Index:=1, Layout:=ppLayoutTitle).SlideIndex
ActiveWindow.Selection.SlideRange.Layout = ppLayoutBlank 

Second, we insert pictures to each slide and put them in fixed position precisely.

ActiveWindow.Selection.SlideRange.Shapes.AddPicture(FileName:="picture1.jpg", LinkToFile:=msoFalse, SaveWithDocument:=msoTrue, left:=12, top:=12, Width:=770, Height:=690).Select
' set size of picture
With ActiveWindow.Selection.ShapeRange
.Fill.Transparency = 0#
.Height = 262.38
.Width = 293#
.left = 100#
.top = 50#
End With 

Third, you may need insert textboxes to the slide. Here is sample code.

ActiveWindow.Selection.SlideRange.Shapes.AddTextbox(msoTextOrientationVerticalFarEast, 29.875, 84, 36.125, 348).Select
ActiveWindow.Selection.ShapeRange.TextFrame.WordWrap = msoTrue
With ActiveWindow.Selection.TextRange.ParagraphFormat
.LineRuleWithin = msoTrue
.SpaceWithin = 1
.LineRuleBefore = msoTrue
.SpaceBefore = 0.5
.LineRuleAfter = msoTrue
.SpaceAfter = 0
End With
ActiveWindow.Selection.ShapeRange.ScaleHeight 0.93, msoFalse, msoScaleFromBottomRight
ActiveWindow.Selection.TextRange.ParagraphFormat.Alignment = ppAlignCenter
ActiveWindow.Selection.ShapeRange.TextFrame.TextRange.Characters(Start:=1, Length:=0).Select
With ActiveWindow.Selection.TextRange
.Text = "Sample graphes"
With .Font
.NameAscii = "Arial"
.Size = 18
.Bold = msoFalse
.Italic = msoFalse
.Underline = msoFalse
.Shadow = msoFalse
.Emboss = msoFalse
.BaselineOffset = 0
.AutoRotateNumbers = msoFalse
.Color.SchemeColor = ppForeground
End With
End With
ActiveWindow.Selection.ShapeRange.TextFrame.TextRange.Font.Bold = msoTrue
ActiveWindow.Selection.Unselect 

If you need move to slide to slide, the following code can do that.

ActiveWindow.View.GotoSlide (i) 

In the second step, when we position graphs, we need pixel units instead of inches PowerPoint uses. To convert inches in PowerPoint slide to pixels, the following formula can be used:

number in inches / 2.54 * 72 

By using this formula, you can precisely position your graphs to slides.
