The exact unit of measure for raster images is known as ppi (points per square inch) or dpi (dots per square inch). For instance, an image may be five thousand pixels high by thirty-five hundred pixels wide. The quality of these images is often determined entirely by how many pixels are present in the design. Each point in the painting, just like each pixel in a digital image, is important for the whole picture to turn out right, but taken out of context means very little. The concept of raster images is very similar to pointillist paintings.
