Python: Add Text or Image Watermarks to PowerPoint
Watermarks serve as subtle overlays placed on the slides, typically in the form of text or images, which can convey messages, copyright information, company logos, or other visual elements. By incorporating watermarks into your PowerPoint presentations, you can enhance professionalism, reinforce branding, and discourage unauthorized use or distribution of your material. In this article, you will learn how to add text or image watermarks to a PowerPoint document in Python using Spire.Presentation for Python.

Add a Text Watermark to PowerPoint in Python
Unlike MS Word, PowerPoint does not have a built-in feature that allows to apply watermarks to each slide. However, you can add a shape with text or an image to mimic the watermark effect. A shape can be added to a slide using the ISlide.Shapes.AppendShape() method, and the text of the shape can be set through the IAutoShape.TextFrame.Text property. To prevent the shape from overlapping the existing content on the slide, you'd better send it to the bottom.
The following are the steps to add a text watermark to a slide using Spire.Presentation for Python.
- Create a Presentation object.
- Load a PowerPoint file using Presentation.LoadFromFile() method.
- Get a specific slide through Prentation.Slides[index] property.
- Add a shape to the slide using ISlide.Shapes.AppendShape() method.
- Add text to the shape through IAutoShape.TextFrame.Text property.
- Send the shape to back using IAutoShape.SetShapeArrange() method.
- Save the presentation to a PowerPoint file using Presentation.SaveToFile() method.
- Python
from spire.presentation.common import * from spire.presentation import * # Create a Presentation object presentation = Presentation() # Load a PowerPoint file presentation.LoadFromFile("C:/Users/Administrator/Desktop/input.pptx") # Define a rectangle left = (presentation.SlideSize.Size.Width - 350.0) / 2 top = (presentation.SlideSize.Size.Height - 110.0) / 2 rect = RectangleF(left, top, 350.0, 110.0) for i in range(0, presentation.Slides.Count): # Add a rectangle shape to shape = presentation.Slides[i].Shapes.AppendShape( ShapeType.Rectangle, rect) # Set the style of the shape shape.Fill.FillType = FillFormatType.none shape.ShapeStyle.LineColor.Color = Color.get_Transparent() shape.Rotation = -35 shape.Locking.SelectionProtection = True shape.Line.FillType = FillFormatType.none # Add text to the shape shape.TextFrame.Text = "CONFIDENTIAL" textRange = shape.TextFrame.TextRange # Set the style of the text range textRange.Fill.FillType = FillFormatType.Solid textRange.Fill.SolidColor.Color = Color.FromArgb(120, Color.get_Black().R, Color.get_HotPink().G, Color.get_HotPink().B) textRange.FontHeight = 45 textRange.LatinFont = TextFont("Times New Roman") # Send the shape to back shape.SetShapeArrange(ShapeArrange.SendToBack) # Save to file presentation.SaveToFile("output/TextWatermark.pptx", FileFormat.Pptx2010) presentation.Dispose()
Add an Image Watermark to PowerPoint in Python
To add an image watermark, you need first to create a rectangle with the same size as an image. Then fill the shape with this image and place the shape at the center of a slide. To prevent the shape from overlapping the existing content on the slide, you need to send it to the bottom as well. The following are the steps to add an image watermark to a slide using Spire.Presentation for Python.
- Create a Presentation object.
- Load a PowerPoint file using Presentation.LoadFromFile() method.
- Get a specific slide through Prentation.Slides[index] property.
- Load an image using Presentation.Images.AppendStream() method.
- Add a shape that has the same size with the image to the slide using ISlide.Shapes.AppendShape() method.
- Fill the shape with the image through IAuotShape.Fill.PictureFill.Picture.EmbedImage property.
- Send the shape to back using IAutoShape.SetShapeArrange() method.
- Save the presentation to a PowerPoint file using Presentation.SaveToFile() method.
- Python
from spire.presentation.common import * from spire.presentation import * # Create a Presentation object presentation = Presentation() # Load a PowerPoint file presentation.LoadFromFile("C:/Users/Administrator/Desktop/input.pptx") # Load an image stream = Stream("C:/Users/Administrator/Desktop/logo.png") image = presentation.Images.AppendStream(stream) stream.Close() # Get width and height of the image width = (float)(image.Width) height = (float)(image.Height) # slideSize = presentation.SlideSize.Size # Loop through the slides in the presentation for i in range(0, presentation.Slides.Count): # Get a specific slide slide = presentation.Slides[i] # Add a shape to slide shape = slide.Shapes.AppendShape(ShapeType.Rectangle, RectangleF((slideSize.Width - width )/2, (slideSize.Height - height)/2, width, height)) # Fill the shape with image shape.Line.FillType = FillFormatType.none shape.Locking.SelectionProtection = True shape.Fill.FillType = FillFormatType.Picture shape.Fill.PictureFill.FillType = PictureFillType.Stretch shape.Fill.PictureFill.Picture.EmbedImage = image # Send the shape to back shape.SetShapeArrange(ShapeArrange.SendToBack) # Save to file presentation.SaveToFile("output/ImageWatermark.pptx", FileFormat.Pptx2013) presentation.Dispose()

Python: Protect or Unprotect PowerPoint Presentations
PowerPoint presentations often contain sensitive information, such as financial data, trade secrets, or personal details. When sharing these files via email or cloud storage, it is important to prevent unauthorized individuals from accessing or viewing them. To protect the content of your PowerPoint presentation, there are various security measures you can employ. For instance, you can implement password protection, or make the presentation as final or read-only. In certain situations, you may find the need to unprotect a password-protected or encrypted PowerPoint presentation. This may be necessary when you need to share the file with the public or when the password is no longer needed. In this article, we will explain how to protect or unprotect a PowerPoint presentation in Python using Spire.Presentation for Python.
