Creating outlines in Adobe Illustrator is a fundamental technique used to trace existing images, create vector-based designs, and extract specific elements from photographs. It involves converting raster images (made up of pixels) into vector graphics (defined by mathematical curves and points), allowing for crisp and scalable results.
Outlines are valuable in various aspects of graphic design. They provide precise and editable vector paths that can be scaled indefinitely without losing quality, making them suitable for logos, icons, typography, and illustrations. Moreover, outlines enable designers to isolate and manipulate specific elements within an image, allowing for creative recompositions and design explorations.
