DPtoTP

Converts an array of points in display coordinates to tablet coordinates.

BOOL DPtoTP( LPPOINT lppt, int cPnt )

Parameters
lppt

Address of an array of POINT structures to convert to tablet coordinates. This parameter cannot be NULL.

cPnt

Number of POINT structures to convert.

Return Value
Returns TRUE if the conversion was successful; otherwise, returns FALSE.

Comments
Because of possible rounding errors, the DPtoTP and TPtoDP functions are not guaranteed to be perfect inverses of each other.

The calling application must avoid overflow by passing in points that are within the limits of the current physical display.
