The Inking Process
This chapter introduces the inking process, in which an application collects
and manipulates ink data written by the user. The inking process is a logical
next step from the writing process, described in the preceding chapter. In the
writing process, the application provides the means for the user to enter ink. In
the inking process, the application assembles the ink data, optionally
modifies it, and applies it to some task.
The inking process pertains to ink data collected for its own sake rather than
immediately passed on to a recognizer for interpretation. Although an
application can later submit gathered data to a recognizer, the inking process deals
with ink that "stays ink" rather than serving as transitory symbols immediately
converted into recognized characters.
The HPENDATA data object serves as the major instrument in the inking process. The first
part of this chapter describes HPENDATA and the various application programming interface (API) functions that serve
it. Example code fragments throughout illustrate how to store and manage ink
data with the HPENDATA services.
An application can refer to the data in an HPENDATA object by stroke and point indices, or time intervals. For viewing and
manipulating ink data that falls within specified time intervals, the Pen API
provides the HINKSET object. The last section of this chapter, "The HINKSET Object," examines HINKSET and its corresponding API functions.
