Free Vector Airplane Images

Vector images like these Free Vector Airplane Images use lines to create images, photographs can't normally be turned into a vector image. A bitmap or raster file uses dots, they are not created in the same manner. In a Vector images file everything is a separate item. If you have an apple with a worm in it you can change the apple to green at anytime and the worm can become a tiger if you so choose without altering or affecting the other object. Vector images like these Free Vector Airplane Images must have been created as a vector file. You cannot take a raster file created in Photoshop (for example) and save it with an.eps,.ai., or.cdr extension and have it magically become a vector file. Once a bitmap always a bitmap unless recreated or traced.
