Export Image in Slices (File Menu)

This exports the selected objects as several sections (or "slices"). This has two main uses:

When exporting bars as each button needs to be a separate graphic

For large, complex graphics for web pages. You can export areas of flat color as, for example, 2-color GIFs and highly detailed areas as JPEGs or 256 color GIFs. This can reduce the amount of data the viewer has to download.

Before you can slice an image, you must name the objects you want to use for slicing. Use either the Name Gallery or New name on the Selector Tool Infobar.
