Encoding Images: Bitmaps
All pictures on a computer are stored as 1s and 0s.
The simplest way is as a BITMAP image by turning your picture into pixels.
A pixel is a single block of colour that makes up a picture. It is a bit like a tile in a mosaic.
By creating a grid of pixels we can create a picture using pixels.
The colour of each pixel is stored using binary. The more colours we use, the more bits per pixel are needed.
Simple Bitmap Images
Create a simple 8px by 8px black and white bitmap image
Colour Bitmaps Images
Create a simple 8px by 8px four colour bitmap image
Using Hexadecimal
Create a simple 16px by 16px sixteen colour bitmap image
