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

# CTM
Under the hood, Pycairo uses a matrix to calculate the transformations. This is called the **current transform matrix (CTM)** and forms part of the `Context` object.

Initially, the CTM is set to a unit matrix that corresponds to a one-to-one mapping. The `translate`, `scale`, and `rotate` operations update the CTM. The effect is cumulative so, for example, if you apply a `translate` followed by a `rotate`, the value of the CTM will reflect the combined operation.

The diagram below shows how this process works:
