Remove Hyperlinks from Word in Python
To delete all hyperlinks in a Word document at once, you'll need to find all the hyperlinks in the document and then create a custom method FlattenHyperlinks() to flatten them. The following are the detailed steps.
- Create a Document object.
- Load a sample Word document using Document.LoadFromFile() method.
- Find all the hyperlinks in the document using custom method FindAllHyperlinks().
- Loop through the hyperlinks and flatten all of them using custom method FlattenHyperlinks().
- Save the result document using Document.SaveToFile() method.
- Python
from spire.doc import *
from spire.doc.common import *
# Find all the hyperlinks in a document
def FindAllHyperlinks(document):
hyperlinks = []
for i in range(document.Sections.Count):
section = document.Sections.get_Item(i)

- Create a PdfDocument object.
- Load a PDF document using PdfDocument.LoadFromFile() method.
- Get a specified page using PdfDocument.Pages[pageIndex] property.
- Get the original rotation angle of the page using PdfPageBase.Rotation.value property.
- Increase the original rotation angle by desired degrees.
- Apply the new rotation angle to the page using PdfPageBase.Rotation property
- Save the result document using PdfDocument.SaveToFile() method.
- Python
from spire.pdf.common import *
from spire.pdf import *
# Create a PdfDocument object
pdf = PdfDocument()
# Load a PDF document
pdf.LoadFromFile("Sample.pdf")
# Get the first page
page = doc.Pages.get_Item(0)
# Get the original rotation angle of the page
rotation = int(page.Rotation.value)
# Rotate the page 180 degrees clockwise based on the original rotation angle
rotation += int(PdfPageRotateAngle.RotateAngle180.value)
page.Rotation = PdfPageRotateAngle(rotation)
# Save the result document
pdf.SaveToFile("RotatePDFPage.pdf")
pdf.Close()
Rotate All Pages in PDF in Python
Spire.PDF for Python also allows you to loop through each page in a PDF file and then rotate them all. The following are the detailed steps.

- Load a PDF document using PdfDocument.LoadFromFile() method.
- Loop through each page in the document.
- Get the original rotation angle of the page using PdfPageBase.Rotation.value property.
- Increase the original rotation angle by desired degrees.
- Apply the new rotation angle to the page using PdfPageBase.Rotation property.
- Save the result document using PdfDocument.SaveToFile() method.
- Python
from spire.pdf.common import *
from spire.pdf import *
# Create a PdfDocument object
pdf = PdfDocument()
# Load a PDF document
pdf.LoadFromFile("Input.pdf")
# Loop through each page in the document
for i in range(pdf.Pages.Count):
page = pdf.Pages.get_Item(i)
# Get the original rotation angle of the page
rotation = int(page.Rotation.value)
# Rotate the page 180 degrees clockwise based on the original rotation angle
rotation += int(PdfPageRotateAngle.RotateAngle180.value)
