Writing a Recognizer
A recognizer is a dynamic-link library (DLL) that interprets lines of ink as
characters and symbols. Version 2.0 of the Pen API allows a pen-based
application to install multiple recognizers and use them selectively. Each recognizer
should specialize in recognizing a particular set of symbols instead of trying to
handle many different types. Besides keeping the recognizer code manageable,
this approach lets an application choose among several available recognizers to
fulfill its current recognition needs.
The recognizer developer must know both sides of the interface between
application and recognizer. The foregoing chapters, particularly Chapter 5, "The
Recognition Process," should be read before venturing into this one.
Such a developer should also have some familiarity with the coding
requirements of a DLL. For information about how to write a DLL, see the Guide to Programming manual in the Microsoft Windows Software Development Kit. In addition, the
"Writing a Dynamic-Link Library for Windows" chapter in the MASM version 6.1 Programmer's Guide offers valuable information about DLL coding requirements.
This chapter describes the framework of a recognizer DLL and the functions it
must export. The final section presents a sample recognizer called SREC. The
source file for SREC resides in the SAMPLES\PEN\SREC subdirectory.

Nostalgia .Net |
|
.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
