Vector programs can take an existing raster image and convert it into a vector image with a slight loss of quality. The conversion technology from raster to vector is also rocketing forward. In short vector images are becoming the new standard. Many printers are starting to require vector image files from their clientele. Vector images have just recently been recognized by web browsers and are just starting to look more lifelike. Think of raster images as the record and vector images as the CD or MP3. This technology is rapidly improving and I believe will make raster images obsolete in the foreseeable future. In my opinion vector images are the wave of the future. The programs that create vector images, like Adobe Illustrator, still cannot produce the same effects that raster image programs, such as Adobe Photoshop, can. Vectors are great for cartoons and logos, but generally have not had been good to use for more realistic images and graphics. The disadvantage is that this technology is somewhat newer and is not quite up to the quality of raster images. You can use the same file to make a stamp or a billboard and the quality will remain the same. The advantage of vector images is that the file size is usually smaller than raster images and they look the same no matter what size you scale them too. A vector image is like a set of blueprints that tells your software program what to display on your monitor. The disadvantage is that if the files can take up a lot of memory and the images become pixelated, or fuzzy, if they are blown up too large.Ī vector image uses code, or mathematical equations, to create a picture. This technology has been around since the beginning of the camera so it very popular. Raster images are popular for the internet and print. A raster image is similar to a puzzle with each piece being a different color. In some cases, however, such files may be converted so as to enable use.What the heck is a vector image anyway? And how do you tell if an image is a raster? When should you use a vector image and which type of image should you be asking your artist for? Sit back and relax because I’ll be answering all these questions and more!Ī raster image uses pixels, or tiny squares, to create a picture. bmp is Bitmap Image File – a raster graphics image file format used to store bitmap digital images, independently of the display device.Īlthough word processors, spreadsheet programs and presentation applications (such as the Microsoft Office suite) may be suitable for creating files for office or Internet use, they are not recommended for creating digital art for print. gif is Graphics Interchange Format – Raster image format best for simple images made up of solid colors with no gradients. A proprietary file that allows the user to work with the images’ individual layers even after the file has been saved. psd is Photoshop Document – is a layered image file used in Adobe PhotoShop. png is Portable Networks Graphics – Raster image format best for displaying simple images and supports transparency tif – Raster image format best for high-resolution photos. tiff is Tagged Image File Format – Sometimes displayed as. jpeg – this raster image format is best for displaying photographic images on web browsers. jpg is Joint Photographic Experts Group – Sometimes displayed as. Raster graphics are rendered images on a pixel-by-pixel basis and they are fantastic when handling shading and gradients. Raster graphics are wonderful for rich, full-color images such as photographs. This is a raster graphic or bitmap graphic. If you put a different color in each square and then, you back away from the grid, the individual squares blend together to make up a picture. In order to understand what a raster graphic is, imagine a large grid that is made up of many squares (pixels) of all the same size. The CDR file format is recognized by the majority of image editing programs.Ī raster graphic or image is made up of pixels. The.ai filename extension is used by Adobe Illustrator.ĬorelDraw (.cdr) is a file format which was developed by the Corel Corporation and is used mainly for vector graphic images and drawings. Adobe Illustrator (.ai) is a proprietary file format developed by Adobe Systems for representing single-page vector-based drawings in either.
