SAMPLE: Annotating a Text File with Ink

ID: Q90486

The information in this article applies to:

Microsoft Windows for Pen Computing, version 1.0

SUMMARY

An advantage for pen computers would be the ability to add handwriting to a text file. This process is known as annotation. An application that implements full-scale annotation must address several issues, including movement, saving ink to a file, delayed recognition, and using gestures. One of the most basic issues is movement.

ANNOTATE demonstrates one scrolling algorithm that scrolls the ink and the text file appropriately.

For an application to attach ink to a specified position of a text file, it must scroll and repaint the ink in the appropriate position as the text moves. The ANNOTATE sample application demonstrates one of many possible scrolling algorithms. ANNOTATE also demonstrates dynamically changing ink color and width.

ANNOTATE calls the RedisplayPenData function to redisplay the ink and the DuplicatePenData function to save ink over the life of the application. ANNOTATE can serve as a foundation for other pen-centric annotation applications.
