TouchPanelCalibrateAPoint (Windows CE 5.0)
This function converts noncalibrated points to calibrated points.
VOID TouchPanelCalibrateAPoint(INT32 UncalX,INT32 UncalY,INT32* pCalX,INT32* pCalY);
Parameters
- UncalX
[in] Noncalibrated x-coordinate. - UncalY
[in] Noncalibrated y-coordinate. - pCalX
[out] Pointer to the returned calibrated x-coordinate. - pCalY
[out] Pointer to the returned calibrated y-coordinate.
Return Values
None.
Remarks
A factor of four is hidden in the calculations of x and y. This provides sub-pixel accuracy to GWES. This improves accuracy for handwriting recognition support. No header file declares this value, so it agrees with the divisor used by GWES in Touch.cpp.
The transform coefficients are already in vCalcParam.
Requirements
OS Versions: Windows CE 1.0 and later.
Header: Tchddi.h.
Link Library: Tchmain.lib.
