![]() BMP, TIFF, GIF and JPEG are some of the raster image file formats available. Fortunately, there are already image compression techniques and algorithms that have been made to address that problem. Since raster graphics store much information, they require large file sizes and they can be a bit of a hassle to work with. Each point just stores the value at that location, although it can point to a look. ![]() Vector graphics are better suited for typesetting and graphic design. The corner coordinates and grid spacing define the x and y coordinates for every point in the grid, which can be calculated as needed rather than stored (computer computation may be cheaper than storage and file access). Vector graphics, on the other hand, is able to scale up to any resolution because of it uses geometry and mathematical equations to define images rather than directly mapping pixels in a grid. The image will look blocky and pixelated. It can be scaled down with no changes in quality, but when the resolution is scaled up, quality loss is unavoidable. The main disadvantage of raster graphics is that it is dependent on resolution. The word raster was borrowed from the term ‘raster scan,’ which was how old CRT monitors displayed images, by magnetically steering a concentrated electron beam line by line to form an image. This means that an image with a 1280×720 resolution will contain 921,600 pixels while a full HD 1920×1080 image will have 2,073,600 pixels, which will obviously give it a bigger file size when compared to the former. Selecting a region changes the language and/or content on file size of a raster image depends also on the size of the image, which is determined by the number of pixels being used in the image. “Since vectors are based around formulas, a vector image can scale at high resolution to virtually unlimited sizes.” Many printing processes can only work with vector file input. ![]() If you have a business logo saved in a vector format, it can be resized to fit on a billboard with no problems or reduced to be printed on a ballpoint pen or business card. Since vectors are based around formulas, a vector image can scale at high resolution to virtually unlimited sizes. “The key difference between vector and raster files comes down to utility.” In other words, don’t print an image from Instagram at poster size and expect it to look as crisp as it did onscreen. ![]() Because of this set number, if a raster file is printed at a larger dimension than what it was designed for, it will appear visibly grainy and pixelated because the dots that compose the image are forced to grow larger as the medium they’re printed on grows. Raster files are composed of a set number of pixels. The key difference between vector and raster files comes down to utility. svg: The Scalable Vector Graphics format is based in XML (a markup language used widely across the Internet that's readable by both machines and humans). It’s useful for the web, where it can be indexed, searched, and scripted. pdf: The Portable Document Format is built for the exchange of documents across platforms and is editable in Adobe Acrobat. eps: Encapsulated PostScript is an older type of vector graphics file.eps files don’t support transparency in the way more modern file formats like. ai: Short for Adobe Illustrator, this file is commonly used in print media and digital graphics, such as logos. The most common types of vector files are: Because they can infinitely adjust in size without losing resolution, vector files are more versatile for certain types of tasks than raster files. Raster files are composed of the colored blocks commonly referred to as pixels. Vector files are images that are built by mathematical formulas that establish points on a grid. It’s important to understand when to use each image type and the best file extension for particular situations. Both image types may be saved with several different file extensions. When you’re working digitally, there are two kinds of image file types: raster and vector.
