what does the term "Vector art" mean? It looks good.

First let me explain that in the digital world there are two types of images. There is a bitmap and vector images. Anything you see or print on your computer is one of these.

A bitmap image is an image made up of very small dots of color all squeezed together to make a whole image. When you take a picture with a digital camera the camera records the data and it is displayed in the form of pixels on your screen. The same is true of scanning. Think of it as BITS of color arranged on a MAP to make the whole picture. Lets say you are using a 6 mega pixel camera. The chip in the camera creates 6 million pixels arranged in bitmap form to make your image that you can manipulate and output. With this format there are limitations on size both shrinking and enlarging. shrinking the image may blur it and you will lose detail as the program interpolates the pixels together. Enlarging can cause "pixelation" as the program duplicates pixels and blends them. This is when you start seeing square edges on what should be straight lines in the image. I have said enough about bitmap.

Vector images are most simply put a formula that tells where all the pixels are to be displayed or dots printed on a map that is fully scalable. Lets say you want your logo to be printed on your checks and on a billboard. One vector file should take car of both. In the past vector art meant "line art" and usually still does. Thanks to adobe however vector has become very sophisticated. I have seen vector drawings that were hard to tell that they were not real photos.

Although there are many programs to create and edit bitmap and vector images Adobe is the leader in the industry. Photoshop is mainly used for creating and editing bitmap images however it will handle some vector properties. Illustrator is used to create "vector art" but will also handle bitmap images.

One of the best ways to create really good vector art is to use a bitmap image and draw over it in Illustrator. Illustrator also has something called "live trace" that will convert a bitmap image to a vector image.

This is how we get to "vector art".
Google "vector art" and you will see some amazing stuff.
