Basically there are two types of computer graphics, bitmaps and vectors. Bitmap files such as jpegs or gifs contain information on each and every individual pixel while a vector file is object orientated and mathematically contains information on individual objects as to there shape, position, color, etc. Well, there are a number of advantages to using vector graphics the most important being quality. You may have noticed that when you resize a bitmap image upward the quality degrades, vector objects can be resized with virtually no loss of image quality. As well you can deform a vector object and retain it's integrity.
Size is also a factor, vector files tend to be smaller than bitmaps.
There are some limitations on vector graphics. For one, you can't create photographic type images, for that bitmaps are necessary but, for crisp high quality graphics, vectors are the way to go. Vector graphics are particularly suited to rendering cartoons and clipart. With that in mind I'll walk you through the creation of a 'toon cat and along the way introduce you to some of the basic PSP7 vector tools and procedures. First of all you'll need to familiarize yourself with the basic vector tools on the tool bar, don't worry there are only four of them.
