Illustrator is a popular Adobe application for creating vector graphics. Unlike bitmap images, vector graphics are mathematically generated and retain detail when resized. Because of this precision, vector processes are often used to create business images, such as logos and banners. You can vectorize existing images using Illustrator’s Live Trace function. Click the “Tracing presets and options” menu arrow icon located next to the “Live Trace” button on the control panel. Willa Dunn has been writing since 1970.
