Proper presentation of a PDF document is critical for maintaining its accuracy and professionalism. By checking the orientation and rotation of each PDF page, you can confirm that all elements, including diagrams and images, are displayed correctly as intended on the viewing device or platform, thus avoiding confusion or misinterpretation of content. In this article, you will learn how to detect the orientation and rotation angle of a PDF page in Python using Spire.PDF for Python.
Install Spire.PDF for Python
This scenario requires Spire.PDF for Python. It can be easily installed in your Windows through the following pip command.
pip install Spire.PDF

Detect PDF Page Orientation in Python
Page orientation is determined by the relationship between page width and height. Using Spire.PDF for Python, you can compare these two values to detect whether a page is landscape (width greater than height) or portrait (width less than height). The following are the detailed steps.
- Create 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.
- Compare the values of page width and height to detect the page orientation.
- Print out the result.
- Python
from spire.pdf.common import *
from spire.pdf import *
# Create a PdfDocument object
pdf = PdfDocument()
# Load a PDF file from disk
pdf.LoadFromFile("SamplePDF.pdf")
# Get the first page
page = pdf.Pages[0]
# Get the width and height of the page
Width = page.Size.Width
Height = page.Size.Height
# Compare the values of page width and height
if Width > Height:
print("The page orientation is Landscape.")
else:
print("The page orientation is Portrait.")
Detect PDF Page Rotation Angle in Python
PDF pages can be rotated by a certain angle. To detect the rotation angle of a PDF page, you can use the PdfPageBase.Rotation property. The following are the detailed steps.
- Create a PdfDocument instance.
- Load a PDF file using PdfDocument.LoadFromFile() method.
- Get a specified page using PdfDocument.Pages[] property.
- Get the rotation angle of the page using PdfPageBase.Rotation property, and then convert it to text string.
- Print out the result.
- Python
from spire.pdf.common import *
from spire.pdf import *
# Create a PdfDocument object
pdf = PdfDocument()
# Load a PDF file from disk
pdf.LoadFromFile("Sample.pdf")
# Get the first page
page = pdf.Pages[0]
# Get the rotation angle of the current page
rotationAngle = page.Rotation
rotation = str(rotationAngle)
# Print out the result
print("The rotation angle is: " + rotation)
