RCRESULT rectBoundInk Field Is in Client Coordinates

• Microsoft Windows for Pen Computing version 1.0

When an application receives the WM_RCRESULT message, the rectBoundInk field of the RCRESULT structure reports the bounds on the input ink in client coordinates, not in tablet coordinates.

When the Microsoft Recognizer receives the RCRESULT structure returned from the RecognizeInternal function, the Recognizer builds the rectBoundInk rectangle, as well as performing other tasks. The rectBoundInk rectangle is built if the following four conditions are met:

• The RCO_COLDRECOG flag is not set
• The ink width is greater than 0 (zero)
• hpendata is valid (the GetPenDataInfo function returns success)
• The bounding rectangle in the PENDATAHEADER structure is not empty

Also note that the rectBoundInk variable may contain area outside the area specified in the rectBound variable in the RC structure. In other words, while the ink drawn is constrained by rc.rectBound, rcresult.rectBoundInk is based on the data collected from the pen.
