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

In this lesson, we will look at a slightly more complex polygon: a useful arrow shape. This example will illustrate a few techniques that can be used to design polygons.

# A simple arrow
Here, we will see how to draw an arrow, as shown in the picture below. We need the following parameters to make an arrow: position of the shape on the canvas (`x` and `y` coordinates), size of the shape (`height` and `width`), length of the tail (`a`), and inset (`b`). Here is a pictorial representation of these parameters:
