Detailed Description

Callback functions for AIGradientSuite::IterateGradient().

The specified callbacks are invoked with information for each iteration segment of the gradient.

For example, if you select a gradient object and choose Object>Expand, and specify 10 paths, the plug-in uses this function to create the 10 paths that simulate the gradient. For each of the paths:

The setColor procedure is first called to set the color state.
Then, beginFill is called to let the plug-in know that a new path is about to be created.
Then, moveTo is called to let the plug-in know where the first point is.
Then, a sequence of calls to either lineTo or
curveTo builds up the path.
Finally, endFill is called to let the plug-in know that the path is finished.
