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

We can draw a line between two points, for instance points `(x1, y1)` and `(x2, y2)`, like this:

```
ctx.move_to(x1, y1)
ctx.line_to(x2, y2)
```
Now, we will look at a couple of other examples.

# Drawing a line of given length and angle
In this case, we will see how to draw a line that:
- Starts from the point `(x1, y1),`
- Is at an angle `a` radians from the x-axis,
- And has a length `r`.

Here is how a line is drawn:
