Bitmap image is a less versatile image type than a vector image. Bitmap contains parts of image in each of the pixels, however, vector give more information regarding an image vis-a-vis, shapes, colors and where they should appear. Thereby creating a detailed map about the image that can be used in the vector. Vector graphic is more detailed hence it looks good in any size, colors come out precise. So even when images are taken way large in size than the normal one, image will look as good as the one in original size.
Converting bitmap into vector graphic is changing its pixel form into a mathematical equation which describes the image or gives instructions as to where each component of the image should be provided. This conversion of bitmap graphic to vector graphic can prove to be tedious and time consuming task. You could also experience inaccuracies. There are many software available for converting a bitmap or raster into a vector graphic.
The vector graphic covers color shades, shapes, proportion and placement to most accuracy, so whether you want to put your picture on billboard or on the logo, it will come out looking exactly the way it has been originally designed. Plus, vector graphics allows editing to be done on the image and video editing platforms with ease. There are many software for graphics design, however, number of programs available in Corel software alone for purpose of design and drawing is unparalleled. Using Corel to convert from bitmap to vector graphic and ability of integrating that vector graphic in wherever you require is quite a boon.
