Data Within an HPENDATA Object

Figure 4.1 illustrates the internal structure of an HPENDATA object.

Windows stores the pen data in memory in a simple hierarchy. Data points are grouped by strokes in the order in which they are entered. The HPENDATA block of memory begins with a descriptive header area. The following sections describe the data points, the stroke headers, and the main header that make up an HPENDATA object.

Note that the drawing in Figure 4.1 is not to scale. The data points generally represent a much larger proportion of the memory block than the header components.
