![]() ![]() Generally, raster images are better suited for photographs or “true-to-life” graphics. The end result, however, defines which image type is more suitable for a particular purpose. So when are raster or vector images suitable to use? Truth be told, both types of images can be used for any purpose. When Should You Use Raster Or Vector Images? Raster images, on the other hand, can contain complex shaded gradients. For a vector image to contain gradients it must be rasterized and therefore cannot be considered a true vector graphic. These block colors will typically be encased by lines. True vector images will ONLY contain block colors. For example, what size would a 3” by 2” raster image be if it had a PPI of 8? It would be 24px x 16px (3×8 + 2×8) and would contain 384 pixels in total. The size of raster images is defined in resolution and pixels. Vector images may have a defined size in inches or cm, but this size can be changed easily. Raster images as mentioned are formed using individual pixels. Vector images are formed using paths and formulas. The formulation is another major difference between bitmap vs vector images. Vector images are known as resolution-independent. This is because the mathematical formulas would simply be changed. It would retain its quality regardless of size. If you had a vector image containing a square you could increase the size of that square indefinitely. For example, if you increased the size of an 800×600 raster to 1024×768 it would still contain the same number of pixels that it did at the original size. Instead, it simply explodes the size of the pixels within the image. Scaling a raster image does not increase the PPI. If you scale a raster image up, it will lose quality. Raster images have a limited quality vector images do not. Quality is a key difference of raster vs vector. There are several main areas to consider – quality, formulation, and content. Here we look at the difference between raster and vector images. What Is The Primary Difference Between Raster And Vector? Thus, if a vector image contains a gradient, it has been partially rasterized. It is not possible to create a gradient using mathematical formulas. Moreover, true vector images cannot contain color gradients. Vector images do not lose quality when scalingĭue to the complex mathematical formulas involved, vector images generally have a larger file size.Vector images are suitable for any size of print media.Vector images can be scaled up and down indefinitely.Examples of vector images include SVG, EPS and PDF.Quality is generally not measured as the images have a limitless scale.Created using paths and mathematical formulas.We have listed some of the main pointers of vector images below: If you had a person’s face for example there could be a mathematical shape for the eyes, mouth, and nose. A vector image does the same with shapes. Each piece of glass represents a part of the image. A stained glass window is composed of shaped blocks of solid color glass. Vector images are comparable to a stained glass window or block line painting. A vector square, for example, would have four paths – one for each side of the shape. These formulas explain to the path how it should be formed. The paths within a vector image contain mathematical formulas. True form vector images are created solely using line art and solid colors. So what is a vector image? Vector images are built using paths and mathematical formulas. The following are some popular programs used to create raster images: you will visibly see the individual pixels the image will look blocky as a result. If you try to increase the size of a raster image, it will lose quality. The last point is particularly important. Raster web images are typically saved at 72 or 96PPI.300PPI or more is desirable for print media.A higher PPI results in a higher-quality raster image.Examples of raster images include JPEG, PNG, GIF, and BMP.Quality is measured in PPI (Pixels Per Inch, not Personal Protection Insurance!).We have listed some of the main pointers of raster images below: If you view thousands of colored pixels together, however, they form a coherent raster image. If you viewed one single pixel, it wouldn’t mean anything. If you look at the whole mosaic, however, you can see an image. ![]() If you look at an individual tile – it is just that – a tile. Think of a tiled mosaic – a mosaic is made up of hundreds of colored tiles. What is a raster image?
