(The shaded text is the Gradient Stop List.)

Gradient Fills consist of three elements: a list of gradient stops, a shading specification, as well as some attributes.

Two attributes

are available on gradient fills.

A gradient stop list is a list of locations and colors that make up the gradient fill. Positions are specified as percentages.

The shading specification specifies the two possible kinds of gradient fills: linear, or path based. A linear fill follows a straight-line direction as specified by the angle of the line. A path-based fill follows the contours of a well-defined path (such as a shape, circle, or rectangle).
