What is a the difference between a Vector and a Raster Image?
A vector image stores image information as mathematical data. A vector image can store more colors and shapes in less space while resizing smoothly. The lines, curves, and fills are all recalculated during scaling to create a more precise image. Vector images are easily converted to raster images. The raster image stores pixel data and has to save information about the color of every pixel in the image. A high resolution raster image is usually large and when you resize a raster image, the data doesn’t scale well; if you shrink it, you lose pixel data as larger areas merge into smaller ones. If you enlarge it, you end up with a jagged image as single-pixel data has to fill a multiple pixels area via interpolation. Raster images can rarely be perfectly converted to vector images.
