The main difference between vector and raster images is that rasters are pixel-based, while vectors are created using mathematical formulas for lines, points, and curves. This composition combines a photograph with hand-drawn elements added in Procreate to create one combined raster image. Examples of Raster ImagesĪ mixed-media raster image of a cactus and hand-drawn cartoon elements.

Because they are made up of tiny pixels, rasters are also better suited to display subtle color gradations and blends.

Raster images are also commonly used for web graphics, as they are generally available in more accessible and shareable file formats. Generally, a raster must have a resolution of 300 DPI (dots per inch, which is approximately the same as pixels per inch) for printing. Rasters can also be used for printed projects, but they must meet certain specifications. Instead, photographs are best displayed in a raster format. Because vectors are made up of mathematical lines and curves, they don’t accurately display photographic images. Raster images are used in digital photography. However, as you zoom in, you will increasingly be able to see the individual pixels, which can make the edges of the image look blurry or jagged.Ĭommon raster file types include. When viewed from far away, the pixels form a complete picture. The more pixels, the higher the image resolution, and the larger it can be resized. A raster image is a compilation of many individual colored pixels.
