Adobe Illustrator CS is a vector-based drawing program. This software allows users to compose and edit vector graphics images interactively on the computer screen. These vector graphics are saved in many popular file formats such as EPS, SVG and PDF.etc.
Illustrator CS is a great software tool. Because the interface is similar to Adobe's Photoshop, it is a good choice for someone who is already familiar with Photoshop or who will need to use it often. You can even drag and drop files between the two programs.
