Architecture of the Pen API
Note the version change in this paragraph from the "Windows" section.
In version 1.x of Pen Windows, the application was required to call RegisterPenApp in order to tell the system to convert all edit controls to handwriting edit
(hedit) controls. With Pen API version 2.0, however, this is not necessary; all
edit controls in applications are automatically converted. If the application
is version-stamped as a Windows 95-based application, the conversion is
automatic; otherwise, applications version-stamped as Windows 3.1-based applications
require the call to RegisterPenApp that was required for Pen Windows, version 1.x.
- Information about handwriting recognizers has been added to this paragraph in
the "Recognizer" section.
Although many recognizers may be available to an application, only one serves
as the system default recognizer. This is the recognizer that Windows
automatically installs and calls by default. To use other recognizers, an application
must first specifically install them. (For information about how to install
multiple recognizers, see Chapter 5, "The Recognition Process.") The Microsoft
Handwriting Recognizer (GRECO.DLL in US, RODAN.DLL in Japan) is provided as the
default system recognizer on most OEM tablet installations of Microsoft pen
services. GRECO.DLL recognizes all European letters, numerals, and punctuation, with
emphasis on English, French, and German. RODAN.DLL recognizes Kanji, Kana, and
other Japanese characters. An application can set up a different system
recognizer by identifying the new file in the Windows registry. Appendix A explains how
to set up a new default recognizer.
- The following section was added at the end of the "Recognizer" section.
