About Geometric Styles

A style is a group of stylistic variations applied to a shape. QuickDraw GX provides two major categories of stylistic variations: geometric variations, which include pen width, dashes, patterns, and so on, and typographic variations, which include font, font size, type style, and so on.

Both types of stylistic variation are encapsulated in a style object. Like a shape object, a style object is a data structure. Each style object has a group of properties, and each style property represents a different stylistic variation.
