Create and Apply Slide Masters in PowerPoint Presentations
Every PowerPoint presentation in PowerPoint, regardless of whether it is newly created or not, will have at least one slide master. Developers can modify the default master or create new ones and apply them to slides with Spire.Presentation for Python to achieve a consistent style and content layout across the presentation.
The detailed steps for creating new slide masters and applying them to the slides in a presentation file are as follows:
- Create an object of Presentation class and load a PowerPoint presentation using Presentation.LoadFromFile() method.
- Create slide masters using Presentation.Masters.AppendSlide() method.
- Use the methods under IMasterSlide class to set the backgrounds, customize color schemes, insert images, shapes, and text, etc.
- Apply the slide masters to specific slides through ISlide.Layout property.
- Save the presentation using Presentation.SaveToFile() method.
- Python
from spire.presentation.common import *
from spire.presentation import *
# Create an instance of Presentation class
pres = Presentation()
# Load a Presentation file
pres.LoadFromFile("Sample.pptx")
# Add a cover slide master and a body slide master
master1 = pres.Masters.AppendSlide(pres.Masters.get_Item(0))
coverMaster = pres.Masters.get_Item(master1)
master2 = pres.Masters.AppendSlide(pres.Masters.get_Item(0))
bodyMaster = pres.Masters.get_Item(master2)
# Set background images for the two slide masters
pic1 = "Background1.jpg"
pic2 = "Background2.jpg"
rect = RectangleF.FromLTRB (0, 0, pres.SlideSize.Size.Width, pres.SlideSize.Size.Height)
coverMaster.SlideBackground.Fill.FillType = FillFormatType.Picture
image1 = coverMaster.Shapes.AppendEmbedImageByPath (ShapeType.Rectangle, pic1, rect)
coverMaster.SlideBackground.Fill.PictureFill.Picture.EmbedImage = image1.PictureFill.Picture.EmbedImage
bodyMaster.SlideBackground.Fill.FillType = FillFormatType.Picture
image2 = bodyMaster.Shapes.AppendEmbedImageByPath (ShapeType.Rectangle, pic2, rect)
bodyMaster.SlideBackground.Fill.PictureFill.Picture.EmbedImage = image2.PictureFill.Picture.EmbedImage
# Insert a logo to the body slide master
logo = "Logo.png"
bodyMaster.Shapes.AppendEmbedImageByPath(ShapeType.Rectangle, logo, RectangleF.FromLTRB(pres.SlideSize.Size.Width - 110, 10, pres.SlideSize.Size.Width - 10, 110))
# Insert text to the body slide master
shape = bodyMaster.Shapes.AppendShape(ShapeType.Rectangle, RectangleF.FromLTRB(pres.SlideSize.Size.Width - 210, 110, pres.SlideSize.Size.Width - 10, 150))
shape.Fill.FillType = FillFormatType.none
shape.Line.FillType = FillFormatType.none
shape.TextFrame.Text = "Spire.Presentation"
# Set the color scheme for the two slide masters
coverMaster.Theme.ColorScheme.Accent1.Color = Color.get_Red()
coverMaster.Theme.ColorScheme.Accent2.Color = Color.get_Blue()
bodyMaster.Theme.ColorScheme.Accent1.Color = Color.get_Brown()
coverMaster.Theme.ColorScheme.Accent2.Color = Color.get_Green()
# Apply the first master with layout to the first slide
pres.Slides.get_Item(0).Layout = coverMaster.Layouts.GetByType(SlideLayoutType.Title)
# Apply the second master with layout to other slides
for i in range(1, pres.Slides.Count):
pres.Slides.get_Item(i).Layout = bodyMaster.Layouts.GetByType(SlideLayoutType.TitleAndObject)
# Save the document
pres.SaveToFile("output/CreateAndApplySlideMaster.pptx", FileFormat.Pptx2016)
pres.Dispose()
Modify Slide Masters in PowerPoint Presentations
A presentation can have multiple slide masters, which can be applied to different slides to achieve a unified style application and modification for different types of slides.
The Presentation.Masters.get_Item() method in Spire.Presentation for Python allows developers to retrieve the specified slide master in the presentation by index and modify the master. The following step-by-step example demonstrates how to retrieve a slide master and modify its background, color scheme, and embedded images:
- Create an object of Presentation class and load a PowerPoint presentation using Presentation.LoadFromFile() method.
- Get a slide master through Presentation.Masters property.
- Use the methods under IMasterSlide class to change the background, set the color scheme, delete and insert text and images, etc.
- Save the presentation using Presentation.SaveToFile() method.
- Python
from spire.presentation.common import *
from spire.presentation import *
# Create an object of Presentation
pres = Presentation()
# Load a PowerPoint presentation
pres.LoadFromFile("output/CreateAndApplySlideMaster.pptx")
# Get the third slide master
master = pres.Masters[2]
# Change the background
master.SlideBackground.Type = BackgroundType.Custom
master.SlideBackground.Fill.FillType = FillFormatType.Solid
master.SlideBackground.Fill.SolidColor.Color = Color.get_LightBlue()
# Change the color sheme
master.Theme.ColorScheme.Accent1.Color = Color.get_Red()
master.Theme.ColorScheme.Accent2.Color = Color.get_Green()
# Remove the pictures in the slide master
pictures = [shape for shape in master.Shapes if isinstance(shape, SlidePicture)]
for picture in pictures:
master.Shapes.Remove(picture)
# Change the text in the slide master
texts = [shape for shape in master.Shapes if isinstance(shape, IAutoShape)]
for text in texts:
if len(text.TextFrame.Text) != 0:
text.TextFrame.Text = "Spire.Presentation for Python"
# Save the presentation
pres.SaveToFile("output/ModifySlideMaster.pptx", FileFormat.Pptx2016)
pres.Dispose()
Copy Slide Masters Between PowerPoint Presentations
Applying the slide style of a presentation to another presentation can be achieved by copying the slide master between presentations and applying the master style to the specified slides. The following are the steps to copy the slide master between presentations and apply it to the specified slides:
- Create two objects of Presentation class and load two presentation documents using Presentation.LoadFromFile() method.
- Get the slide master of the second presentation using Presentation.Masters.get_Item() method.
- Add the slide master to the first presentation using Presentation.Masters.AppendSlide() method.
- Apply the slide master to the slides in the second presentation through ISlide.Layout property.
- Save the first presentation using Presentation.SaveToFile() method.
- Python
from spire.presentation import *
from spire.presentation.common import *
# Create two objects of Presentation
pres1 = Presentation()
pres2 = Presentation()
# Load two PowerPoint documents
pres1.LoadFromFile("Sample.pptx")
pres2.LoadFromFile("Template.pptx")
# Get the slide master of the second presentation
master = pres2.Masters.get_Item(0)
# Add the slide master to the first presentation
index = pres1.Masters.AppendSlide(master)
# Apply the slide master to the first presentation
pres1.Slides.get_Item(0).Layout = pres1.Masters.get_Item(index).Layouts.GetByType(SlideLayoutType.Title)
for i in range(1, pres1.Slides.Count):
pres1.Slides.get_Item(i).Layout = pres1.Masters.get_Item(index).Layouts.GetByType(SlideLayoutType.TitleAndObject)
# Save the first presentation
pres1.SaveToFile("output/CopySlideMaster.pptx", FileFormat.Pptx2013)
pres1.Dispose()
pres2.Dispose()

TIFF is a popular image format used in scanning and archiving due to its high quality and support for a wide range of color spaces. On the other hand, PDFs are widely used for document exchange because they preserve the layout and formatting of a document while compressing the file size. Conversion between these formats can be useful for various purposes such as archival, editing, or sharing documents.
In this article, you will learn how to convert PDF to TIFF and TIFF to PDF using the Spire.PDF for Python and Pillow libraries.
Install Spire.PDF for Python
This situation relies on the combination of Spire.PDF for Python and Pillow (PIL). Spire.PDF is used to read, create and convert PDF documents, while the PIL library is used for handling TIFF files and accessing their frames.
The libraries can be easily installed on your device through the following pip command.
pip install Spire.PDF pip install pillow
Convert PDF to TIFF in Python
To complete the PDF to TIFF conversion, you first need to load the PDF document and convert the individual pages into image streams using Spire.PDF. Subsequently, these image streams are then merged together using the functionality of the PIL library, resulting in a consolidated TIFF image.
The following are the steps to convert PDF to TIFF using Python.
- Create a PdfDocument object.
- Load a PDF document from a specified file path.
- Iterate through the pages in the document.
- Convert each page into an image stream using PdfDocument.SaveAsImage() method.
- Convert the image stream into a PIL image.
- Combine these PIL images into a single TIFF image.
- Python
from spire.pdf.common import *
from spire.pdf import *
from PIL import Image
from io import BytesIO
# Create a PdfDocument object
doc = PdfDocument()
# Load a PDF document
doc.LoadFromFile("C:\\Users\\Administrator\\Desktop\\Input.pdf")
# Create an empty list to store PIL Images
images = []
# Iterate through all pages in the document
for i in range(doc.Pages.Count):
# Convert a specific page to an image stream
with doc.SaveAsImage(i) as imageData:
# Open the image stream as a PIL image
img = Image.open(BytesIO(imageData.ToArray()))
# Append the PIL image to list
images.append(img)
# Save the PIL Images as a multi-page TIFF file
images[0].save("Output/ToTIFF.tiff", save_all=True, append_images=images[1:])
# Dispose resources
doc.Dispose()
Convert TIFF to PDF in Python
With the assistance of the PIL library, you can load a TIFF file and transform each frame into distinct PNG files. Afterwards, you can utilize Spire.PDF to draw these PNG files onto pages within a PDF document.
To convert a TIFF image to a PDF document using Python, follow these steps.
- Create a PdfDocument object.
- Load a TIFF image.
- Iterate though the frames in the TIFF image.
- Get a specific frame, and save it as a PNG file.
- Add a page to the PDF document.
- Draw the image on the page at the specified location using PdfPageBase.Canvas.DrawImage() method.
- Save the document to a PDF file.
- Python
from spire.pdf.common import *
from spire.pdf import *
from PIL import Image
import io
# Create a PdfDocument object
doc = PdfDocument()
# Set the page margins to 0
doc.PageSettings.SetMargins(0.0)
# Load a TIFF image
tiff_image = Image.open("C:\\Users\\Administrator\\Desktop\\TIFF.tiff")
# Go to the current frame
tiff_image.seek(i)
# Extract the image of the current frame
frame_image = tiff_image.copy()
# Save the image to a PNG file
frame_image.save(f"temp/output_frame_{i}.png")
# Load the image file to PdfImage
image = PdfImage.FromFile(f"temp/output_frame_{i}.png")
# Get image width and height
width = image.PhysicalDimension.Width
height = image.PhysicalDimension.Height
# Add a page to the document
page = doc.Pages.Add(SizeF(width, height))
# Draw image at (0, 0) of the page
page.Canvas.DrawImage(image, 0.0, 0.0, width, height)
# Save the document to a PDF file
doc.SaveToFile("Output/TiffToPdf.pdf",FileFormat.PDF)
# Dispose resources
doc.Dispose()

// Load document content from file
doc.loadFromFile("Sample1.docx");
// Get the body of the document
Body body = doc.getSections().get(0).getBody();
// Create lists for paragraphs and tables
List<Paragraph> paragraphs = new ArrayList<>();
List<Table> tables = new ArrayList<>();
for (int i = 0; i < body.getChildObjects().getCount(); i++) {
// Get the document object
DocumentObject documentObject = body.getChildObjects().get(i);
// If it is a StructureDocumentTag object
if (documentObject instanceof StructureDocumentTag) {
StructureDocumentTag structureDocumentTag = (StructureDocumentTag) documentObject;
// If the tag is "c1" or the alias is "c1"
if (structureDocumentTag.getSDTProperties().getTag().equals("c1") || structureDocumentTag.getSDTProperties().getAlias().equals("c1")) {
for (int j = 0; j < structureDocumentTag.getChildObjects().getCount(); j++) {
// If it is a paragraph object
if (structureDocumentTag.getChildObjects().get(j) instanceof Paragraph) {
Paragraph paragraph = (Paragraph) structureDocumentTag.getChildObjects().get(j);
paragraphs.add(paragraph);
}
// If it is a table object
if (structureDocumentTag.getChildObjects().get(j) instanceof Table) {
Table table = (Table) structureDocumentTag.getChildObjects().get(j);
tables.add(table);
