High-resolution, high-quality clip art is often developed and sold as vector images as well. Keeping a nice library of vector images can save you time because of the ability to resize on the fly.

These files are saved and are used as the basis for raster copies that get used in print and web publishing. Most companies create all of their logos and insignia as vector images. Only illustrations that are made to look like photographs can be created in a vector workspace. You may only need a web logo now, but image how great it would be to have that image ready to use on a banner or merchandise later without having to create it all over again? Photos Because of the way images are created and saved, you will have more flexibility with making changes and be able to use your image at a variety of sizes. 1 option when designing or creating a logo or illustration. Vector images are often saved as native files from the program used to create the image, such as Adobe Illustrator, which may not be available to everyone you need to work with (though widely compatible formats do exist). The most common problem with using vector images is compatibility. Vector images, therefore, are often easy to transmit from one computer to another and over the Internet. Because the files are only identified by mathematical descriptions and not individual pixels, files are often much smaller than those of the raster counterparts. No matter how much you increase a font’s size, for example, its look never changes.Īnother advantage to using vector images is file-size efficiency.

Text is one of the most common types of vector image. You can identify a vector image by looking at its edges - a vector image will always appear smooth no matter how large you make it or how close you zoom in. Because of this defined, formulaic approach to drawing, each image can be sized and scaled repeatedly and limitlessly without losing resolution or beginning to look cloudy or pixelated. Any of the lines and curves in the image can be assigned a color value.

Vector graphics must be created in computer software that is designed to create this intricate wireframe-type image and each line includes defined node positions, node locations, line lengths and curves. Vector images, which are made of thin lines and curves known as paths, are rooted in mathematical theory. Most images on the web are raster files.Vector images, which are made of thin lines and curves known as paths, are rooted in mathematical theory. Raster files saved as vector file formats will still be raster files. However, raster images lose detail and become increasingly blurry when enlarged.Īlthough a vector image can be saved as a raster image, it is not possible to convert a raster image into a vector image. Raster images are best for complex images like photographs, and are more likely to be a widely compatible file format (such as JPG). EMF - Microsoft Office-based vector format.Vector format is an excellent choice for digital illustrations such as logos.Ī vector file can be converted to a raster file, but it will permanently lose the advantages of the vector format.Ĭommon vector file extensions: SVG, EPS, and EMF Vector files are most useful when a graphic needs to be able to handle resizing, as they retain crisp detail when scaled to any size. Each format has advantages and disadvantages in different situations, so knowing the properties of each can help determine which format is the best choice for any project. All digital image files fall into one of two categories: vector or raster.
