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

This is how we set an RGB color in Pycairo:
```
ctx.set_source_rgb(r, g, b)
```
Here, `ctx` is the context and `r`, `g`, and `b` control the amount of red, green, and blue in the color. Each color value is a float between `0.0` and `1.0`, where `0.0` represents none of that particular color and `1.0` represents the maximum amount of that color. Every possible color in Pycairo is represented by some combination of red, green, and blue.



# Primary colors
The primary colors are formed when only one of the RGB colors is present. In other words, pure primary colors are shown with one color at `1.0` and the other two colors have a value of `0.0`. 

This diagram shows the three primary colors set at various intensities:
