Sheet dimensions are expressed in points, not pixels, with one point equaling 1/72 inch. Height and width correspond to standard A4 measurements, which is used by default when creating a canvas. That said, it is essential to know what the measurements of each sheet are when generating the document. This inversion of the Y axis can be a bit confusing at first, but it does not present any additional difficulty, just remember these issues when positioning the objects. That means the Y-position increases as you go up the screen, and the X-position increases as you scroll to the right. Unlike most popular desktop application development libraries, in ReportLab the origin of the coordinates (that is, the (0, 0) position) is at the bottom left. Now when you open the hello-world.pdf file you will find our little message in the bottom left corner of the page.Īs you may have guessed, the first two arguments passed to drawString() indicate the (x, y) position at which the text will appear. The most basic code that we can find using ReportLab is the one that generates an empty PDF document, which is the following.Ĭ. However, you can find the official documentation for the package in its entirety at this link. For the rest of the cases, the low-level API that we will describe in this article will suffice. Generally, the second option is usually more convenient for those who must make exhaustive use of the capabilities of the library when generating documents. ReportLab includes a low-level API for generating PDF documents directly from Python, and a higher-level template language-similar to HTML and the template systems used in web development-called RML. The source code is hosted on this Mercurial repository.
The library is simply installed via pip: pip install reportlab In this post we will be approaching to its general features and main functions to create this type of documents. It is a very extensive library with many features, from small texts and geometric figures to large graphics and illustrations, all of which can be included in a PDF. ReportLab is an open source toolkit for creating PDF documents from Python.
