Adobe Illustrator is used to create vector graphics. Vector graphics are mathematically drawn by a computer allowing users to change the size of a drawing without losing quality. Raster graphics, such as those used in Photoshop, are created using static individual pixels, making them unable to be changed.
Illustrator initially puts an object in a bounding box once it is selected. Multiple bounding boxes appear if multiple objects are selected allowing users to move and change them together. Effects are used in Illustrator to manipulate artwork so that users may apply a change live without damaging the original object. Fonts are difficult to share in Illustrator, as the AI file is not able to be viewed if uncommon fonts are used.
