What Are Vector Images?
Vector images are images described by shapes such as circles and squares, as opposed to bitmap images that are described by pixels – squares of color arranged in a grid. The shapes are precise mathematical descriptions of the image and can be scaled without becoming blurry or “pixelated” (that blocky look that bitmap/raster images so often get when scaled up). Some examples of Vector Images are EPS, AI, PDF, and SVG.
What Are Bitmap Images?
Bitmap images are images that are described by pixels – squares of color arranged in a grid. Bitmap images are also known as raster images. Some Examples of bitmapped images are JPG, GIF, PNG, TIF, and BMP.
Why Use Vector Images?
Vector images are used in most aspects of graphic design and are the preferred format for printing, both on paper and on clothes. The reason for this is that while a bitmap image can look great on the screen, it will normally have to be scaled or color separated when printed. Vector images can handle this type of manipulation without losing quality.
Logos for businesses should always be created as a vector file for maximum usage. With vector-based logos, the image will scale to any size and any application.
What Is Vector Conversion?
There is no easy way to convert a bitmapped file into vector format. You can’t export or resave a bitmapped file and have a true vector file. Vector Conversion is the process of converting a bitmap image to a vector image by means of hand-tracing in a computer program such as Adobe Illustrator.
