Editing the inside (fill) of an object
The OpenOffice.org term for the inside of an object is Area fill. The area fill of an object can be a uniform color, a gradient, a hatching, or a pattern from an image. It can be made partly or wholly transparent and can throw a shadow.
In most cases, you will choose one of the standard fill options, which are all available from the Line and Filling toolbar. You can also define your own area fills; see Chapter 4 of the Draw Guide for details.
