![]() ![]() But with vector images, you're saying, "fill the background with a left-to-right gradient that fades from blue to pink. With raster images, you're basically telling your computer, "this pixel should be blue, the next one should be purple, the one after that should be pink," and so on. If that technical explanation didn't make much sense to you, think of it this way. ![]() Text is one of the most common types of vectors! Objectives: Identify the difference between vector and raster file formats Explain the applications of the two image formats. Difference Between Bitmap and Raster Bitmap noun A set of bits that represents a graphic image, with each bit or group of bits corresponding to a pixel in the image. This formulaic approach allows vector images to be scaled to any size without losing their quality. Vector images, meanwhile, are composed of lines called "paths" and points called "anchors." They dictate how an image should render based on mathematical theory. ![]() Related: How to Use Adobe's Super Resolution to Upscale Images Without Losing Quality This results in an unattractive, blurred image-at least, in most cases. In doing so, you're asking the image editor to add more pixels where there aren't any more. Usually, raster images can't be scaled any larger than their original width and height. Bitmap images tend to have much large file sizes than vector graphics and they are often compressed to reduce their size. Most bitmap images can be converted to other bitmap-based formats very easily. Each pixel contains data that determines its color, such as its hue, saturation, value, transparency, etc. Common bitmap-based formats are JPEG, GIF, TIFF, PNG, PICT, and BMP. Raster images (or bitmaps) are composed of pixels. ![]()
