12 Pixel plotter
This chapter covers:
- Plotting and creating images with a GUI
- Creating a Waffle (A square of squares)
- Setting colored pixels
- Deleting and clearing a pixel
Imagine that you are looking at your favorite image on a screen, like a photo of your pet, a funny meme, or a picture of your best friend. If you look really closely at the image, and I mean really close, with your eyeballs nearly touching the screen, then you may just be able to see that it's made up of lots and lots of tiny little dots.
Each one of these tiny dots is called a pixel and can be set to a particular color. The word pixel is a combination of the two words, "picture element," and it became more commonly used in the context of computer graphics and digital images in the mid-20th century. Pixels are the basic building blocks used to create digital images.
WHAT YOU WILL BUILD
Now let us image that you have a large piece of graph paper, the paper with squares that you use in Math. Each square is like a pixel, and you can color it, in the similar way that the pixels on a screen can be colored. By coloring in each square a specific color, you can create a picture. Images made in this fashion are referred to as pixel art, have a look at Figure 12.1 for some examples. So, a pixel is like a tiny colored dot and when you combine lots of pixels of different colors together, you make cool pixel art.
