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.

## Font size
The `set_font_size` function sets the size of the font and, therefore, the size of any text we create with that font. But, what exactly does the size value mean?

Font size is measured in user units —the same units we use when setting the line width. The font size indicates the height of the text, from the top of the tallest alphabetic character, such as a capital “A”, right down to the bottom of the tail of an alphabetic character, such as “g”. Here is an example of this:
