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.

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.

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()

Hiding and showing slides are two practical features in PowerPoint that allow you to control the visibility of slides during a slideshow. Hiding slides is useful when you want to skip certain slides or temporarily remove them from the presentation without deleting them. Whereas showing slides is helpful when you want to re-display the hidden slides. In this article, we will demonstrate how to hide and show slides in a PowerPoint presentation in Python using Spire.Presentation for Python.

• Hide a Specific Slide in PowerPoint in Python
• Show a Hidden Slide in PowerPoint in Python
• Show All Hidden Slides in PowerPoint in Python

Install Spire.Presentation for Python

This scenario requires Spire.Presentation for Python and plum-dispatch v1.7.4. They can be easily installed in your Windows through the following pip command.

pip install Spire.Presentation

If you are unsure how to install, please refer to this tutorial: How to Install Spire.Presentation for Python on Windows

Hide a Specific Slide in PowerPoint in Python

Spire.Presentation for Python provides the ISlide.Hidden property to control the visibility of a slide during a slideshow. If you don’t want a certain slide to be shown, you can hide this slide by setting the ISlide.Hidden property as True. The detailed steps are as follows.

• Create an object of the Presentation class.
• Load a PowerPoint presentation using Presentation.LoadFromFile() method.
• Get a specific slide using Presentation.Slides[index] property.
• Hide the slide by setting the ISlide.Hidden property as True.
• Save the resulting presentation using Presentation.SaveToFile() method.

from spire.presentation.common import *
from spire.presentation import *

# Create an object of the Presentation class
ppt = Presentation()
# Load a PowerPoint presentation
ppt.LoadFromFile("Sample.pptx")

# Get the second slide and hide it
slide = ppt.Slides[1]
slide.Hidden = True

# Save the resulting presentation to a new .pptx file
ppt.SaveToFile("HideSlide.pptx", FileFormat.Pptx2016)
ppt.Dispose()

Show a Hidden Slide in PowerPoint in Python

To show a hidden slide, you can set the ISlide.Hidden property as False. The detailed steps are as follows.

• Create an object of the Presentation class.
• Load a PowerPoint presentation using Presentation.LoadFromFile() method.
• Get a specific slide using Presentation.Slides[index] property.
• Unhide the slide by setting the ISlide.Hidden property as False.
• Save the resulting presentation using Presentation.SaveToFile() method.

from spire.presentation.common import *
from spire.presentation import *

# Create an object of the Presentation class
ppt = Presentation()
# Load a PowerPoint presentation
ppt.LoadFromFile("HideSlide.pptx")

# Get the second slide and unhide it
slide = ppt.Slides[1]
slide.Hidden = False

# Save the resulting presentation to a new .pptx file
ppt.SaveToFile("ShowSlide.pptx", FileFormat.Pptx2016)
ppt.Dispose()

Show All Hidden Slides in PowerPoint in Python

To show all hidden slides in a PowerPoint presentation, you need to loop through all the slides in the presentation, then find the hidden slides and unhide them by setting the ISlide.Hidden property as False. The detailed steps are as follows.

• Create an object of the Presentation class.
• Load a PowerPoint presentation using Presentation.LoadFromFile() method.
• Loop through the slides in the presentation.
• Check whether the current slide is hidden or not using ISlide.Hidden property. If the result is true, unhide the slide by setting the ISlide.Hidden property as False.
• Save the resulting presentation using Presentation.SaveToFile() method.

from spire.presentation.common import *
from spire.presentation import *

# Create an object of the Presentation class
ppt = Presentation()
# Load a PowerPoint presentation
ppt.LoadFromFile("Sample2.pptx")

# Loop through each slide in the presentation
for i in range(ppt.Slides.Count):
    slide = ppt.Slides[i]
    # Check if the slide is hidden
    if(slide.Hidden):
        # Unhide the slide
        slide.Hidden = False

# Save the resulting presentation to a new .pptx file
ppt.SaveToFile("ShowAllHidenSlides.pptx", FileFormat.Pptx2016)
ppt.Dispose()
