The QR-code is situated right under the company's name, contains the right contact information and actually encodes the contact data we've provided. # Code to generate a QR code LayoutElement So let's start by declaring that first: # New imports from .image.barcode import Barcode, BarcodeTypeįrom .layout_element import LayoutElement ![]() We also need the coordinates of the QR-code (we'll be adding something special to it later on). ![]() In order to easily present this content side by side, we're going to be using a Table. The next step is adding the QR-code and the contact information. We'll start by adding the title, such as "Your Company": # New imports from .text.paragraph import Paragraphįrom .color import HexColor Now that we have an empty canvas to work from, let's add the basic content. # Future content-rendering-code to be inserted here # Attempt to store PDF with open( "output.pdf", "wb") as pdf_file_handle: Layout: PageLayout = SingleColumnLayout(page) Let's see what that looks like in code: from import Documentįrom .page_layout.multi_column_layout import SingleColumnLayoutįrom .page_layout.page_layout import PageLayout Creating an empty Page and appending it to the Document.We'll be making a flyer like this, to promote a supposed product belonging to a supposed company:īuilding a PDF document in borb typically follows the same couple of steps: It's oftentimes easier to make a sketch, and work towards it, rather than building blind, so feel free to sketch out a flyer on a piece of paper you have lying around, and letting that creativity flow unto the canvas. Installing borbīorb can be downloaded from source on GitHub, or installed via pip: $ pip install borb What We’ll Be Making In this guide, we'll take a look at how to generate a flyer containing custom graphics (represented by PDF operators). It offers both a low-level model (allowing you access to the exact coordinates and layout if you choose to use those) and a high-level model (where you can delegate the precise calculations of margins, positions, etc to a layout manager). ![]() In this guide, we'll be using borb - a Python library dedicated to reading, manipulating and generating PDF documents. In fact, PDF is based on a scripting language - PostScript, which was the first device-independent Page Description Language. To achieve this, PDF was constructed to be interacted with via something more like a programming language, and relies on a series of instructions and operations to achieve a result. It was developed to be platform-agnostic, independent of the underlying operating system and rendering engines. The matplotlib animation examples may have inspiration for this kind of optimization.The Portable Document Format (PDF) is not a WYSIWYG (What You See is What You Get) format. This is only an option if you do similar plots, but if they are very similar, it can speed up things a lot. This is close to twice as fast as the initial example for me. # Now instead of plotting, we update the current line: You can save quite a bit more, by reusing the lines: line = ax.plot(X, Y) # but should interfere with autoscaling see also below about that You can reuse the figure and axes in this example: import matplotlibĪx.clear() # or even better just line.remove() So if your plots are similar you can safe a lot of "setting up" by reusing elements, just like you will find in animation examples for matplotlib. Matplotlib has a lot of overhead for creation of the figure, etc. ![]()
