Pycairo

In this course, you will use Python’s Pycairo library to draw complex shapes. So if you have an appetite for virtual reality, or game development, then this course will serve you well.

You will start with basic concepts like: What is the difference between pixel and vector graphics? After that, you will learn to make basic drawings and then you will move on to complex shapes. Throughout, you will cover important concepts like transform and state, working with text, gradients, and a whole lot more.

By the time you finish this course, you will have a powerful new library at your disposal, and you’ll be able to construct beautiful graphics that users will love.

## Storing vector graphics

**Vector images** take a different approach to storing images. Instead of storing the pixels that make up the image, a vector graphics file stores a list of instructions for how to draw the image. Here is an example of a scalable vector graphics (SVG) file. SVG  is a widely-used vector format that is based on XML. It is supported by all the modern web browsers and is the main file format used by the popular open-source vector image editor, Inkscape.

Don’t worry about the details. We will probably never have to edit, or even look at, an SVG file in real life. This is just an illustration, used to give us an idea of what a vector graphics file might look like:
