However, vectors should be used at radical scale or for clarity of defined edges in simple shapes, such as logos and illustrations. If something requires more detail at an adequate scale, raster images are optimum. But don’t sweat it: Because you can convert vector to raster. /rebates/&.com252flearning-portal252fraster-vs-vector. Similarly, if the image is too small, it can become indistinct. If you scale up a raster image too far, it becomes grainy and pixelated. A PNG is a raster that is, pixel-based image format. Vector and raster data both have their advantages and disadvantages. Perhaps the most fundamental difference between PNG and SVG is that one is a raster file type and the other is vector. In the vector world, we have points, lines, and polygons that consist of vertices and paths. Raster images should be used for photos while vectors should be used for logos and illustrations. In the raster world, we have grid cells representing real-world features. Because the scaling versatility, vectors are excellent for logos, illustrations, sign writing and embroidery. SVG, EPS, PDF and AI are common file formats for vector graphics. Often containing less detail than a raster image, a vector will retain appearance regardless of size and can be scaled infinitely.Īlthough you can include gradients and shadows in a vector, a true vector graphic is comprised of line art that is filled with colour. Vector images are made up of points, lines, and curves that are based upon mathematical equations, rather than pixels. For digital deliverables a 72dpi is sufficient whereas print requires a minimum of 300dpi. T hey cannot be scaled without sacrificing quality. The key Difference between Raster and Vector Graphics is that Raster graphics are made up of pixels, while vector graphics are created using mathematical. Comparison Table of Raster vs Vector Raster, Vector Raster images are also known as Bitmap images and are made up of small dots known as pixels. The greater the dpi and dimensions, the higher the quality, and often the file size. Quality of a raster image is often dictated by the dpi (dots per inch) and the overall dimensions of the image. JPG, GIF and PNG are all examples of different types of raster files. This means raster images are capable of rendering complex, multi-coloured visuals, such as photographs. Paths consists of complex mathematics that tells your monitor and printer how to draw an image. The path is mainly a line which is stroked with color. Here it also means the same thing, a line with direction. In physics you might have heard the term vectors which means magnitude with direction. This makes vector files incredibly versatile. Unlike raster image, vector image is made of path. But, what do they actually mean and how are they different? Raster imagesĪ raster image (also known as bitmap) is made up of individual pixels and each of those pixels contributes to the overall image. The main practical difference in the two types is that vector graphics can be scaled without any loss of quality. So, raster vs vector? You may have heard of them and just nod politely when they are mentioned.
