Raster images are stored in pixels. Vector images are
stored as shapes. All sorts of editing operations can be conducted on Vector
images with ease. This makes it important to stored web images in Vector form
rather than Raster form.
In order to understand why
web images need to be converted from the raster to the vector format the two
types of formats must be known. It is also important to know what are the pros
and cons of storing images in each of the format. Images that are stored in the
raster format stores images in the form of pixels. Raster format images can be
edited with the help of a bitmap editor. If a Raster image has to be edited then a change has to be made to all
the pixels that comprise the image. It is a mammoth and tedious task. Vector
images are those images, which are stored in the form of shapes. This format is
easier to handle and enables the functionality of shaping, sizing, orienting
and moving an image with much aplomb.
