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()
