![]() ![]() Each pixel is assigned a color value and packing many dots into a small area creates the illusion of a crisp image. A raster image is created by a series of pixels or dots. The most common raster image is a photograph, though with a graphics program like Adobe Photoshop artists can create raster images other than photographs. Vector graphics are the best choice for business identity print work, logos, promotional posters, and major illustrations.Ĭommon vector formats include EPS (Encapsulated PostScript), WMF (Windows Metafile), AI (Adobe Illustrator), CDR (CorelDraw), DXF (AutoCAD), SVG (Scalable Vector Graphics) and PLT (Hewlett Packard Graphics Language Plot File) Raster Images.When you are designing something for large scale like banners, signage, vehicle wraps and other large format items.Vector files simply do not handle photographic imagery as well as raster files.You can make them larger or smaller without a loss of image quality. Vector Graphics are resolution independent.It is easy to convert a vector graphic to raster if needed.Vector graphic files sizes are usually much smaller than raster files making them easier to store and share.In this example we have enlarged a vector version of our logo.Īs you can see, the enlarged version retains the crisp edges of the original. By combining paths that are straight or curved and various colors and shading very detailed illustrations can be created.īecause the image is created using mathematical precision using programs like Adobe Illustrator or CorelDraw, the resulting files can easily be resized larger or smaller without any loss in image quality. Vector images are constructed of lines (also called paths) and are created by software programs that use mathematical calculation to determine size, shape and color of each line. ![]() Each of the graphic types have their own particular strengths and limitations and understanding these differences is essential to achieving the best results. When it comes to creating graphics, designers must choose to express their creativity using either vector or raster graphics. ![]()
