While working with PDF files programmatically, you may need to rotate the pages in a PDF. This is required to change the orientation of the PDF pages from portrait to landscape or vice versa. To accomplish that, this article provides you with the easiest solution of how to rotate PDF files in Python. The step-by-step guide and code sample will demonstrate how to switch the orientation of the pages in a PDF file.
Python Library to Rotate PDF Files
To rotate PDF files, we will use Aspose.PDF for Python. It is a powerful library to seamlessly create, process, and convert PDF files. You can use the following pip command to install the library from PyPI.
pip install aspose-pdf
Rotate a PDF File in Python
You can rotate the pages in a PDF and change their orientation to landscape or portrait. In both cases, you only need to swap the values of page’s height and width and set the angle at which the content of the page will be rotated. This will automatically change the orientation from portrait to landscape and landscape to portrait.
The following are the steps to rotate a PDF file in Python.
- First, create an instance of the Document class and initialize it with the input PDF file’s path.
- Then, start a loop to access each page of the PDF using Document.pages collection.
- In each iteration, update the height and width of the page and set rotation angle.
- Finally, call Document.save() method to save the updated PDF file.
The following code sample shows how to rotate the pages in a PDF in Python.
The above code sample rotates all the pages in the PDF file. However, you can modify it to rotate a single page or certain pages only. In addition, we have rotated each page’s content to 90 degrees. You can also use other angles available in aspose.pdf.Rotation enum. The other values of aspose.pdf.Rotation enum include ON180, ON270, and NONE.
