#How to install pypdf2 on mac pdf

Here is how first page of original (left) and watermarked (right) pdf file looks like: Finally, we close the original pdf file object and the new file object. Firstly we open the new file object and write pdf pages to it using write() method of pdf writer object.

Now, we have to write the pdf pages to a new pdf file.

Then, we add page to pdf writer object using addPage() method of pdf writer class by passing the rotated page object. Now, we rotate the page by rotateClockwise() method of page object class. We get page object by getPage() method of pdf reader class.

Now, we iterate each page of original pdf.

For writing to pdfs, we use object of PdfFileWriter class of PyPDF2 module.

Rotated pages will be written to a new pdf.

For rotation, we first create pdf reader object of the original pdf.

Some important points related to above code: Here you can see how the first page of rotated_example.pdf looks like ( right image) after rotation: PyPDF2 may simply be unable to work with some of your particular PDF files. There isn’t much you can do about this, unfortunately. As such, PyPDF2 might make mistakes when extracting text from a PDF and may even be unable to open some PDFs at all.

Note: While PDF files are great for laying out text in a way that’s easy for people to print and read, they’re not straightforward for software to parse into plaintext.

Page object has function extractText() to extract text from the pdf page.

pdf reader object has function getPage() which takes page number (starting form index 0) as argument and returns the page object.

Now, we create an object of PageObject class of PyPDF2 module.

For example, in our case, it is 20 (see first line of output).

numPages property gives the number of pages in the pdf file.

Here, we create an object of PdfFileReader class of PyPDF2 module and pass the pdf file object & get a pdf reader object.pdfReader = PyPDF2.PdfFileReader(pdfFileObj).We opened the example.pdf in binary mode. and saved the file object as pdfFileObj.

PyPDF2 is a python library built as a PDF toolkit. We will be using a third-party module, PyPDF2. In this article, we will learn, how we can do various operations like: PDFs can contain links and buttons, form fields, audio, video, and business logic. Invented by Adobe, PDF is now an open standard maintained by the International Organization for Standardization (ISO). It is used to present and exchange documents reliably, independent of software, hardware, or operating system. In-fact, they are one of the most important and widely used digital media.
