Creating area fills
Impress comes with many pre-defined area fills in four categories: colors, gradients, hatching patterns, and bitmaps. If none of the provided fills is satisfactory, you can fully customize them and create new fills. The following sections describe how to create new fills and how to apply them.
On each page of the Area dialog, to modify the characteristics of an existing fill, change those characteristics in the dialog and then click the Modify button. (In some cases, you can also change the name of the fill in the same step.) However, it is recommended to create new fills or modify custom fills, and not change the pre-defined ones.
