# importing the required modules import PyPDF2 def PDFrotate(origFileName, newFileName, rotation): # creating a pdf File object of original pdf pdfFileObj = open(origFileName, 'rb') # creating a pdf Reader object pdfReader = PyPDF2.PdfFileReader(pdfFileObj) # creating a pdf writer object for new pdf pdfWriter = PyPDF2.PdfFileWriter() # rotating each page for page in range(pdfReader.numPages): # creating rotated page object pageObj = pdfReader.getPage(page) pageObj.rotateClockwise(rotation) # adding rotated page object to pdf writer pdfWriter.addPage(pageObj) # new pdf file object newFile = open(newFileName, 'wb') # writing rotated pages to new file pdfWriter.write(newFile) # closing the original pdf file object pdfFileObj.close() # closing the new pdf file object newFile.close() def main(): # original pdf file name origFileName = 'fancy.pdf' # new pdf file name newFileName = 'rotated_example.pdf' # rotation angle rotation = 270 # calling the PDFrotate function PDFrotate(origFileName, newFileName, rotation) if __name__ == "__main__": # calling the main function main() |
Now if you execute this python script app.py by running this command like below
python app.py
You can see the result like this
