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

Increase the Margins of a PDF Document in Python

In Spire.PDF for Python, there isn't a direct method to modify the margins of an existing PDF document. However, you can increase the margins by creating a new PDF document with a page size equal to the original document's page size plus the increased margin values. Then, copy and paste (draw) each page of the original document into the appropriate place on the new document page.

The following are the steps to increase the margins of a PDF document using Python.

1. Create a PdfDocument object called "originalPdf" and load the original PDF document.
2. Create another PdfDocument object called "newPdf" for creating a new PDF document.
3. Specify the desired increase values for the top, bottom, left, and right margins.
4. Calculate the new page size by adding the margin increase values to the original page dimensions.
5. Create a template based on the original PDF page using PdfPageBase.CreateTemplate() method.
6. Add a new page to the "newPdf" document with the calculated page size using PdfDocument.Pages.Add() method.
7. Draw the template onto the new page at the appropriate location to using PdfTemplate.Draw() method.
8. Repeat steps 5-7 for each page in the original PDF document.
9. Save the "newPdf" object to a PDF file.

from spire.pdf.common import *
from spire.pdf import *

# Create a PdfDocument object
originalPdf = PdfDocument()

# Load a PDF file
originalPdf.LoadFromFile("C:\\Users\\Administrator\\Desktop\\Input.pdf")

# Get the first page
firstPage = originalPdf.Pages[0]

# Create another PdfDocument object for creating new document
newPdf = PdfDocument()

# Set the increase values of the margins
marginsToAdd = newPdf.PageSettings.Margins
marginsToAdd.Top = 40
marginsToAdd.Bottom = 40
marginsToAdd.Left = 40
marginsToAdd.Right = 40

# Calculate the new page size
sizeF = SizeF(firstPage.Size.Width + marginsToAdd.Left + marginsToAdd.Right, firstPage.Size.Height + marginsToAdd.Top + marginsToAdd.Bottom)

# Iterate through the pages in the original document
for i in range(originalPdf.Pages.Count):

    # Create a template based on a specific page
    pdfTemplate = originalPdf.Pages[i].CreateTemplate()

    # Add a page to the new PDF
    page = newPdf.Pages.Add(sizeF)

    # Draw template on the page
    pdfTemplate.Draw(page, 0.0, 0.0)

# Save the new document
newPdf.SaveToFile("Output/IncreaseMargins.pdf", FileFormat.PDF)

# Dispose resources
originalPdf.Dispose()
newPdf.Dispose()

Reduce the Margins of a PDF Document in Python

Similarly, you can reduce the margins by creating a new PDF document with a page size equal to the page size of the original document minus the margin value to be reduced. Then, copy and paste (draw) each page of the original document into the appropriate place on the new document page.

To reduce the margins of a PDF document using Python, follow these steps:

1. Create a PdfDocument object called "originalPdf" and load the original PDF document.
2. Create another PdfDocument object called "newPdf" for creating a new PDF document.
3. Specify the desired reduction values for the top, bottom, left, and right margins.
4. Calculate the new page size by subtracting the margin value to be reduced from the original page size.
5. Create a template based on the original PDF page using PdfPageBase.CreateTemplate() method.
6. Add a new page to the "newPdf" document with the calculated page size using PdfDocument.Pages.Add() method.
7. Draw the template onto the new page at the appropriate location using PdfTemplate.Draw() method.
8. Repeat steps 5-7 for each page in the original PDF document.
9. Save the "newPdf" object to a PDF file.

from spire.pdf.common import *
from spire.pdf import *

# Create a PdfDocument object
originalPdf = PdfDocument()

# Load a PDF file
originalPdf.LoadFromFile("C:\\Users\\Administrator\\Desktop\\Input.pdf")

# Get the first page
firstPage = originalPdf.Pages[0]

# Create another PdfDocument object
newPdf = PdfDocument()

# Set the reduction value of the margins
topToReduce = 20.0
bottomToReduce = 20.0
leftToReduce = 20.0
rightToReduce = 20.0

# Calculate the new page size
sizeF = SizeF(firstPage.Size.Width - leftToReduce - rightToReduce, firstPage.Size.Height - topToReduce - bottomToReduce)

# Iterate through the pages in the original document
for i in range(originalPdf.Pages.Count):

    # Create a template based on a specific page
    pdfTemplate = originalPdf.Pages[i].CreateTemplate()

    # Add a page to the new PDF
    page = newPdf.Pages.Add(sizeF, PdfMargins(0.0))

    # Draw template on the page
    pdfTemplate.Draw(page, -leftToReduce, -topToReduce)

# Save the new document
newPdf.SaveToFile("Output/ReduceMargins.pdf", FileFormat.PDF)

# Dispose resources
originalPdf.Dispose()
newPdf.Dispose()

Modifying PDF documents to suit various usage scenarios is a common task for PDF document creators and managers. Among these operations, splitting and merging PDF pages can assist in reorganizing PDF content for printing, typesetting, etc. By using Python programs, developers can easily split one page from a PDF document to several pages or merge multiple PDF pages into a single page. This article will demonstrate how to use Spire.PDF for Python for splitting and merging PDF pages in Python programs.

• Split One PDF Page into Several PDF Pages with Python
• Merge Multiple PDF Pages into a Single Page with Python

Install Spire.PDF for Python

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

pip install Spire.PDF

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

Split One PDF Page into Several PDF Pages with Python

With Spire.PDF for Python, developers draw a PDF page on a new PDF page using the PdfPageBase.CreateTemplate().Draw(newPage PdfPageBase, PointF) method. When drawing, if the current new page cannot fully accommodate the content of the original page, a new page is automatically created, and the remaining content is drawn on it. Therefore, we can create a new PDF document and control the drawing result by specifying the page size to achieve specified division of PDF pages horizontally or vertically.

Here are the steps to vertically split a PDF page into two separate PDF pages:

• Create an object of PdfDocument class and load a PDF document using PdfDocument.LoadFromFile() method.
• Get the first page of the document using PdfDocument.Pages.get_Item() method.
• Create a new PDF document by creating an object of PdfDocument class.
• Set the margins of the new document to 0 through PdfDocument.PageSettings.Margins.All property.
• Get the width and height of the retrieved page through PdfPageBase.Size.Width property and PdfPageBase.Size.Height property.
• Set the width of the new PDF document to the same as the retrieved page through PdfDocument.PageSettings.Width property and its height to half of the retrieved page's height through PdfDocument.PageSettings.Height property.
• Add a new page in the new document using PdfDocument.Pages.Add() method.
• Draw the content of the retrieved page onto the new page using PdfPageBase.CreateTemplate().Draw() method.
• Save the new document using PdfDocument.SaveToFile() method.

from spire.pdf import *
from spire.pdf.common import *

# Create an object of PdfDocument class and load a PDF document
pdf = PdfDocument()
pdf.LoadFromFile("Sample.pdf")

# Get the first page of the document
page = pdf.Pages.get_Item(0)

# Create a new PDF document
newPdf = PdfDocument()

# Set the margins of the new PDF document to 0
newPdf.PageSettings.Margins.All = 0.0

# Get the width and height of the retrieved page
width = page.Size.Width
height = page.Size.Height

# Set the width of the new PDF document to the same as the retrieved page and its height to half of the retrieved page's height
newPdf.PageSettings.Width = width
newPdf.PageSettings.Height = height / 2

# Add a new page to the new PDF document
newPage = newPdf.Pages.Add()

# Draw the content of the retrieved page onto the new page
page.CreateTemplate().Draw(newPage, PointF(0.0, 0.0))

# Save the new PDF document
newPdf.SaveToFile("output/SplitPDFPage.pdf")
pdf.Close()
newPdf.Close()

Merge Multiple PDF Pages into a Single Page with Python

Similarly, developers can merge PDF pages by drawing different pages on the same PDF page. It should be noted that the pages to be merged are preferably in the same width or height, otherwise it is necessary to take the maximum value to ensure correct drawing.

The detailed steps for merging two PDF pages into a single PDF page are as follows:

• Create an object of PdfDocument class and load a PDF document using PdfDocument.LoadFromFile() method.
• Get the first and second pages of the document using PdfDocument.Pages.get_Item() method.
• Create a new PDF document by creating an object of PdfDocument class.
• Set the margins of the new document to 0 through PdfDocument.PageSettings.Margins.All property.
• Get the width and height of the two retrieved pages through PdfPageBase.Size.Width property and PdfPageBase.Size.Height property.
• Set the width of the new PDF document to the same as the retrieved pages through PdfDocument.PageSettings.Width property and its height to the sum of the two retrieved pages' heights through PdfDocument.PageSettings.Height property.
• Draw the content of the two retrieved pages onto the new page using PdfPageBase.CreateTemplate().Draw() method.
• Save the new document using PdfDocument.SaveToFile() method.

from spire.pdf import *
from spire.pdf.common import *

# Create an object of PdfDocument class and load a PDF document
pdf = PdfDocument()
pdf.LoadFromFile("Sample1.pdf")

# Get the first page and the second page of the document
page = pdf.Pages.get_Item(0)
page1 = pdf.Pages.get_Item(0)

# Create a new PDF document
newPdf = PdfDocument()

# Set the margins of the new PDF document to 0
newPdf.PageSettings.Margins.All = 0.0

# Set the page width of the new document to the same as the retrieved page
newPdf.PageSettings.Width = page.Size.Width

# Set the page height of the new document to the sum of the heights of the two retrieved pages
newPdf.PageSettings.Height = page.Size.Height + page1.Size.Height

# Add a new page to the new PDF document
newPage = newPdf.Pages.Add()

# Draw the content of the retrieved pages onto the new page
page.CreateTemplate().Draw(newPage, PointF(0.0, 0.0))
page1.CreateTemplate().Draw(newPage, PointF(0.0, page.Size.Height))

# Save the new document
newPdf.SaveToFile("output/MergePDFPages.pdf")
pdf.Close()
newPdf.Close()

# Create a new PDF document
newPdf = PdfDocument()

# Create a PdfUnitConvertor instance
unitCvtr = PdfUnitConvertor()

# Convert the custom size in inches to points
width = unitCvtr.ConvertUnits(12.0, PdfGraphicsUnit.Inch, PdfGraphicsUnit.Point)
height = unitCvtr.ConvertUnits(15.5, PdfGraphicsUnit.Inch, PdfGraphicsUnit.Point)

#Create a new SizeF instance from the custom size, then it will be used as the page size of the new PDF
size = SizeF(width, height)

# Loop through the pages in the original PDF
for i in range(originalPdf.Pages.Count):
    page = originalPdf.Pages.get_Item(i)

    # Add pages of the custom size (12.0*15.5 inches) to the new PDF
    newPage = newPdf.Pages.Add(size, PdfMargins(0.0))

    # Create a PdfTextLayout instance
    layout = PdfTextLayout()

    # Set text layout as one page (if not set the content will not scale to fit page size)

Get PDF Page Size with Python

Spire.PDF for Python offers the PdfPageBase.Size.Width and PdfPageBase.Size.Height properties to get the width and height of a PDF page in points. If you want to convert the default unit of measure to other units, you can use the PdfUnitConvertor class.

The following are the steps to get the PDF page size:

• Initialize a PdfDocument instance.
• Load a PDF file using PdfDocument.LoadFromFile() method.
• Get a specified page using PdfDocument.Pages[] property.
• Get the width and height of the PDF page using PdfPageBase.Size.Width and PdfPageBase.Size.Height properties.
• Initialize a PdfUnitConvertor instance, and then convert the size units from points to other units of measure using PdfUnitConvertor.ConvertUnits() method.
• Add the size information to a StringBuilder instance, and then save the result to a TXT file.

from spire.pdf.common import *
from spire.pdf import *

def AppendAllText(fname: str, text: List[str]):
    fp = open(fname, "w")
    for s in text:
        fp.write(s + "\n")
    fp.close()

inputFile = "Sample1.pdf"
outputFile = "GetPageSize.txt"

# Create a PdfDocument instance
pdf = PdfDocument()

# Load a sample PDF from disk
pdf.LoadFromFile(inputFile)

# Get the first page of the file
page = pdf.Pages[0]

# Get the width and height of page based on "point"
pointWidth = page.Size.Width
pointHeight = page.Size.Height

# Create PdfUnitConvertor to convert the unit
unitCvtr = PdfUnitConvertor()

# Convert size units from points to pixels
pixelWidth = unitCvtr.ConvertUnits(pointWidth, PdfGraphicsUnit.Point, PdfGraphicsUnit.Pixel)
pixelHeight = unitCvtr.ConvertUnits(pointHeight, PdfGraphicsUnit.Point, PdfGraphicsUnit.Pixel)

# Convert size units from points to inches
inchWidth = unitCvtr.ConvertUnits(pointWidth, PdfGraphicsUnit.Point, PdfGraphicsUnit.Inch)
inchHeight = unitCvtr.ConvertUnits(pointHeight, PdfGraphicsUnit.Point, PdfGraphicsUnit.Inch)

# Convert size units from points to centimeters
centimeterWidth = unitCvtr.ConvertUnits(pointWidth, PdfGraphicsUnit.Point, PdfGraphicsUnit.Centimeter)
centimeterHeight = unitCvtr.ConvertUnits(pointHeight, PdfGraphicsUnit.Point, PdfGraphicsUnit.Centimeter)

# Add the size information to a StringBuilder instance
content = []
content.append("The page size of the file in points is (width: " +
               str(pointWidth) + "pt, height: " + str(pointHeight) + "pt).")
content.append("The page size of the file in pixels is (width: " +
               str(pixelWidth) + "pixel, height: " + str(pixelHeight) + "pixel).")
content.append("The page size of the file in inches is (width: " +
               str(inchWidth) + "inch, height: " + str(inchHeight) + "inch).")
content.append("The page size of the file in centimeters is (width: " +
               str(centimeterWidth) + "cm, height: " + str(centimeterHeight) + "cm.)")

# Save to a txt file
AppendAllText(outputFile, content)
pdf.Close()
