About Shape Objects
This section describes the contents of the shape object and summarizes some of the main tasks you can perform with shapes.QuickDraw GX identifies an individual shape object through a shape reference. To obtain information about a shape object, you must send its reference as a parameter to a QuickDraw GX function (except that you can determine if two references identify the same shape object simply by comparing them for equality, and you can examine a reference to see if it is
nil).Shapes are device-independent. Their location, resolution, color, and other properties are not constrained by the characteristics of the display device to which they are drawn.
