AI overview
Raster graphics are images made up of a grid of tiny colored dots called pixels, which together create the picture you see on a screen or printed page. They matter because this simple dot-based approach is how most digital photos and display devices work, making it a fundamental way we create and view images in everyday life.

The smiley face in the top left corner is a raster image. When enlarged, individual pixels appear as squares. Enlarging further, each pixel can be analyzed, with their colors constructed through combination of the values for red, green and blue.
In computer graphics and digital photography, a raster graphic, raster image, or simply raster is a digital image made up of a rectangular grid of tiny colored (usually square) so-called pixels. Unlike vector graphics which use mathematical formulas to describe shapes and lines, raster images store the exact color of each pixel, making them ideal for photographs and images with complex colors and details. Raster images are characterized by their dimensions (width and height in pixels) and color depth (the number of bits per pixel). They can be displayed on computer displays, printed on paper, or viewed on other media, and are stored in various image file formats.
