File sizes can be significantly reduced with the right compression algorithms, making them suitable for sharing via email and other simple methods. If your designs depend on adding effects, filters, and other manipulations, then raster graphics are extremely handy because of their versatility and flexibility.Īside from being useful in a variety of use cases, raster images are also easy to compress and can be transferred over the web in a convenient way. Of course, you can do that for vector files as well, but the effect won't be the same and the effort is disproportionately huge. Effects and filters work better with bitmap or raster images because they're more amenable to pixel-level editing.īlurring backgrounds, using shadows for a more natural look, and using aura-like glows for specific objects in the image are only possible when you use raster images. If you plan to make a lot of edits and add tons of effects to an image, a raster is the best way to go. The main advantage of raster graphics in this context is the ability to achieve deeper hues, better color transitions, and a more natural look. HD is usually enough for a background to be clear and crisp. Some examples of this are mountains, beaches, forests, etc.ĭue to the fact that these are used in a fixed-width manner, pixelation is not an issue as long as the correct resolution is used. Web DesignĪlthough vector images are a favorite for web design, the rich textures for the background can only be achieved by using raster images. Authentic snapshots from various angles are the only way to get this done, so raster graphics step in again to save the day. possible in raster graphics allows designers to deliver stunning visuals.ĭigital Commerce: eCommerce portals depend on realistic photos of actual products in the absence of the 'touch and feel' factor that's so important to the buying decision. these can only be properly represented by raster images the sheer richness of color, lighting, etc. Travel: Exotic locations, picturesque views, alluring nightlife. No company wants to use a computerized image of a pizza to get you drooling, so 'enhanced' photographs of food are the only option. Here are some use cases for raster images:įood: Restaurants and packaged food companies typically use highly visual advertising materials to market their brands. As such, raster would be the appropriate image format to use. The retail industry and other consumer-facing segments often depend on photos of people, places, and things to attract customers. If your design consists of photos, the best option is raster because it renders them more truly than vector images.
Knowing When to Deploy Raster Images in your Designs Using Photos This makes them suitable for a variety of purposes, such as logos, which may be used at varying sizes, including printed for large visual displays like banners, posters, and billboards. The most important aspect of vector images is that, since they're made up of lines and curves, they won't pixelate at any level of magnification. If raster graphics are based on pixels and bits, vector graphics are based on curves and lines, or paths hence, the name vector, which means: a quantity having direction as well as magnitude, especially as determining the position of one point in space relative to another. Raster - Understanding the Basic Difference And that brings us to the term 'vector graphics', which we'll explore next.
#Which are used to create a raster image pdf
Other formats, such as PDF and EPS, often use raster as well as vector graphics in a unified format. Additionally, since bitmaps can contain large amounts of color data, the transitions and other effects appear more realistic. They're all pixel-based or color-map-based, which makes them easy to manipulate at a highly granular level. Here are some of the well-known file formats that make up the raster landscape:Īs you can see, these make up the bulk of image formats commonly used by designers, photographers, and other creative professionals. In fact, digital image capture devices such as cameras and scanners typically render images in pixels, which is ideal for the raster format. Raster images are more common than you might expect. Well-known and Commonly-used Raster Image File Formats For instance, if you're printing out a massive billboard, the images - if you're using raster - need to be of extremely high resolutions. It also means that raster graphics need to be used at the correct resolution depending on the output. Enlarging the image, however, magnifies the bits and makes them visible to us. Although a bitmap or a raster image is made up of bits or pixels, at the right resolution, these bits are indiscernible to the naked eye, which 'fools' our brain into thinking that the lines are smooth.
