Working with PDF files in Python
Add watermarks to PDFs
All of you must be familiar with what PDFs are. In-fact, they are one of the most important and widely used digital media. It uses. It is used to present and exchange documents reliably, independent of software, hardware, or operating system. PDFs can contain links and buttons, form fields, audio, video, and business logic. It is capable of:. This module name is case sensitive, so make sure the y is lowercase and everything else is uppercase. We opened the example. For example, in our case, it is 20 see first line of output. Rotated pages will be written to a new pdf. We get page object by getPage method of pdf reader class. Now, we rotate the page by rotateClockwise method of page object class. Then, we add page to pdf writer object using addPage method of pdf writer class by passing the rotated page object. Firstly we open the new file object and write pdf pages to it using write method of pdf writer object. Finally, we close the original pdf file object and the new file object. Merging PDF files. Here, we create an object pdfMerger of pdf merger class for pdf in pdfs: with open pdf, 'rb' as f: pdfMerger. Splitting PDF file. Output will be three new PDF files with split 1 page 0,1split 2 page 2,3split 3 page 4-end. No new function or class has been used in above python program. Using simple logic and iterations, we created the splits of passed pdf according to the passed list splits. Here is how first page of original left and watermarked right pdf file looks like:. To the passed page object, we use mergePage function and pass the page object of first page of watermark pdf reader object. 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.

It has become one of the most commonly used data formats ever. Up to PDF version 1. Unfortunately, the features from the newer PDF revisions, such as forms, are tricky to implement, and still require further work to be fully functional in the tools. Using various Python libraries you can create your own application in an comparable easy way. This article is part two of a little series on PDFs with Python. In part one we already gave you an introduction into reading PDF documents using Python, and started with a summary of the various Python libraries. An introduction followed that showed how to manipulate existing PDFs, and how to read and extract the content - both the text and images. Furthermore, we showed you how to split documents into its single pages. In this article you will learn how add images to your PDF in the form of watermarks, stamps, and barcodes. For example this is quite helpful in order to stamp or mark documents that are intended to be read by a specific audience, only, or have a draft quality, or to simply add a barcode for identification purposes. In order for this to work you need to have a background image available that comes with the word "DRAFT" on a transparent layer, which you can apply to an existing single-page PDF as follows:. The pdftk tool takes in the PDF file input. Figure 1 shows the output of this action. For more complex actions, like stamping a document with different stamps per page, have a look at the description at the PDF Labs project page. We also show the stamping use-case in this article below, although our example uses the library pdfrw instead of pdftk. In the example below we start with reading the first page of the original PDF document and the watermark. To read the file we use the PdfFileReader class. As a second step we merge the two pages by using the mergepage method. Finally, we will write the output to the output file. This is done in three steps - creating an object based on the PdfFileWriter class, adding the merged page to this object using the addPage method, and writing the new content to the output page using the write method.
