Rather than having a bit in the file for each bit of line drawing we use commands which describe series of points to be connected.ĪS a result a much smaller file is obtained. In vector graphics, the file is created and saved as a sequence of vector statements. In physics: A vector is something which has a magnitude and direction. As a result vector graphics print crisply even when they are enlarged. Vector graphics are best for printing since it is composed of a series of mathematical curves. Making use of sequential commands or mathematical statements or programs which place lines or shapes in a 2-D or 3-D environment is referred to as Vector Graphics. Hence for images which need to scaled to different sizes, we use vector graphics. Scaling down these images is easy but enlarging a bitmap makes it pixelated or simply blurred. Image formats like jpeg and gif are common compressed image formats. We use algorithms which compress images to help reduce these file sizes. As an example, a 640 x 480 image requires information to be stored for 307,200 pixels, while a 3072 x 2048 image (from a 6.3 Megapixel digital camera) needs to store information for a whopping 6,291,456 pixels. Learn more about how they work, what theyre used for, and their pros and cons. The larger the image, the more disk space the image file will take up. Raster image files use pixels to display high-quality photos and graphics. This means a large file needs a large bitmap. Raster images use bit maps to store information.

There are two main types of digital image file raster and vector.Digital photos and detailed graphics both come in raster form. For example, a photograph of a house is made up of a series of pixels colorized to represent the appearance of a house. How to include graphics.h in CodeBlocks? Raster images consist of a rectangular grid of small squares or dots known as pixels.
