Pixel

In digital imaging, a pixel (or picture element^[7]) is a single

point in a raster image. Pixels are normally arranged in a

regular 2-dimensional grid, and are often represented using

dots or squares. Each pixel is a sample of an original image,

where more samples typically provide a more accurate

representation of the original. The intensity of each pixel is

variable; in color systems, each pixel has typically three or

four components such as red, green, and blue, or cyan,

magenta, yellow, and black.
