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.

Computer Graphics in Python and Pycairo

## Simple image with Pycairo
Every image is divided into two parts: 
- Surface (canvas)
- Drawing

Let’s first look at the following slideshow to see how it works. First, we will make a 600 by 400 pixel surface. Then, we will make a red rectangle with a length of 240 pixels and a width of 100 pixels. We want this rectangle to start at 150 pixels from the x-axis, and 100 pixels from the y-axis.

In this lesson, we will practice making our first 2D image using Pycairo.
