![]() A higher resolution raster graphic will have smaller pixels that result in a more detailed image. ![]() The resolution or degree of sharpness present in an image is calculated by determining the number of pixels per inch (PPI) or dots per inch ( DPI). The size of an image might be described as 640 x 480 meaning that there are 640 pixels in a row and 480 pixels in a column. Since raster graphics are represented in a grid structure, the width and height are usually indicated by the number of rows and columns rather than a particular unit of measurement. Raster graphics are composed of tiny squares that work together to create a recognizable picture. Typical file formats for raster graphics include. Raster graphics with a greater number of colors and pixels will require more bits and take up more memory. Every pixel in a bitmap is stored as one or more bits in computer memory. Each pixel or dot displays a unique color and together all of these colored dots create an image. ![]() Raster graphics are digital images represented by a matrix or grid of pixels commonly called a bitmap. ![]()
