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.

## Resizing pixel images
It is *possible* to change the pixel size of an image, but there are certain costs and limitations attached to the process.

We can make a pixel image smaller. For example, we could take a 3000 by 2000 pixel image from a camera, and shrink it down to 600 by 400 pixels to fit on a website, or even to a 150 by 100 thumbnail image. Image editing programs, such as Gimp and Photoshop, will let us resize our image. The smaller image will look perfectly good. Some details will be lost, because of the fewer number of pixels. However, it won’t be any worse than an image that was created at that size in the first place. Here is an example:
