Detailed Description

The pattern style record defines a pattern instance, or an application of a pattern to an art object.

The instance includes a reference to the pattern to use in the fill or stroke and information about how it is transformed, such as scale value.

When a pattern is applied to an object, the pattern's defining art is tiled to paint that object. The pattern fill is tiled from the ruler origin rather than relative to the object. Before the tiling is done, the transformations in the AIPatternStyle record are applied to the pattern art.
