![]() ![]() Enlarging a raster image beyond its 100% size will result in pixelation: that blocky, fuzzy look. While the thousands of pixels in raster images makes them highly detailed, it’s also constraining. They’re used for highly-detailed images, like photographs - images with complex and subtle variations in color, light, and line. In fact, the few examples I’ve seen of such work resulted in a vector file as large as its raster counterpart would have been. It’s difficult to create photorealistic images, like a natural-looking face with all its shades and contours, using vector art. If the Simpsons were drawn on computer (I don’t know if it is or not), Homer would be a vector file. Maps, icons, cartoon-style drawings - they’re all usually in vector format. Vector art is suitable for any image that uses flat swaths of color. Any art that needs to be easily resized should be vector. Where do I use raster art and when do I use vector art?Īs seen in the example above, logos, because they are used so often in so many different environments, should always be vector format. Everything in a vector file remains editable, even text (unless you purposely turn it into outlines), whereas any non-native raster file (JPEG, GIF, PNG, TIFF, BMP) will never contain editable text. A vector file might be 100k in size, while a raster file might be 100Mb. Vector images also result in very small files, while raster images are much, much larger. Because raster images are defined not pixel by pixel, but in mathematical terms, a vector logo that’s two inches tall on your monitor can be printed on a billboard with no loss in quality. The most important difference to remember is that vector graphics are infinitely scalable, while raster graphics are not. What are the implications of these differences? Not knowing the ramifications of each type of image could result in ugly, pixelated art and costly reprints. A vector and raster image, up closeĭepending on what you are designing and how your design is going to be used, you need at some point to decide whether to use art that’s in vector or raster format. *Illustrator EPS files are vector, while Photoshop EPS files are raster. Raster file types include: JPEG, GIF, PNG, TIFF, BMP, PSD and sometimes EPS. Images acquired from a scanner or digital camera are also raster. ![]() Each coordinate has a color value assigned to it. Raster images are formed of pixels that comprise a grid, each defined by an x and y coordinate. Vector file types include: SVG, AI, and sometimes EPS.* A vector file is like a set of instructions describing how the points are connected. Vector images are mathematically-based on the relations between one point and another. ![]()
