As an alternative or companion to a keyboard, you can employ a handwriting pad IM in your application for processing user-drawn numbers, letters, characters, and symbols. The Windows CE handwriting recognition engine currently recognizes all 94 characters of the ASCII character set. In addition, the engine recognizes all of the available glyph characters, known as ideographs, for Chinese, Japanese, and Korean, and produces their corresponding Unicode output.
This section describes the implementation of the Hwx (pronounced wix) functions for processing handwritten characters that are entered by a user on the input panel.
