Graphics Definitions Pixel A pixel is the most basic component of any computer graphic. Pixel stands for picture element. It corresponds to the smallest thing that can be drawn on a computer screen.
Every computer graphic is made up of a grid of pixels.
When these pixels are painted onto the screen, they form an image. Every time it comes to a 0 it draws a white pixel. When it comes to a 1 it draws a black pixel. Sometimes you need more than 1 bit per pixel. This depends on the bit depth of an image.
