It is used to present and exchange documents reliably, independent of software, hardware, or operating system.Invented by Adobe, PDF is now an open standard maintained by the International Organization for Standardization (ISO). PDF stands for Portable Document Format. In-fact, they are one of the most important and widely used digital media.

Python Example Code Code And PDF

All the code and PDF files used in this tutorial/article are available here.1.1WhatisPython?.1.2Installationanddocumentation.Let us try to understand the above code in chunks: Merging multiple pages into a single pageTo install PyPDF2, run following command from command line:This module name is case sensitive, so make sure the y is lowercase and everything else is uppercase. Extracting document information (title, author, вЂ¦)

Python Example Code Pdf File Object

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)

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. PyPDF2 may simply be unable to work with some of your particular PDF files.Here you can see how the first page of rotated_example.pdf looks like ( right image) after rotation:Some important points related to above code: There isnвЂ™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.

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.

page object is converted to watermarked page object using add_watermark() function. Only difference is:WmpageObj = add_watermark(mywatermark, pdfReader.getPage(page)) All the process is same as the page rotation example. Finally, we close the original pdf file object and the new file object.Here is how first page of original (left) and watermarked (right) pdf file looks like:

This will overlay the watermark over the passed page object.And here we reach the end of this long tutorial on working with PDF files in python.Now, you can easily create your own PDF manager!This article is contributed by Nikhil Kumar. To the passed page object, we use mergePage() function and pass the page object of first page of watermark pdf reader object. First of all, we create a pdf reader object of watermark.pdf.
