Everything about Raster graphics
Image display as a 2D grid of pixels
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 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 and color depth. They can be displayed on computer displays, printed on paper, or viewed on other media, and are stored in various image file formats. Wikipedia →
