void LPtoDP( LPPOINT lpPoints, int nCount = 1 ) const;
void LPtoDP( LPRECT lpRect ) const;
lpPoints
Points to an array of points. Each point in the array is a POINT structure or a CPoint object.
nCount
Specifies the number of points in the array.
lpRect
Points to a RECT structure or a CRect object. This parameter is used for the common case of mapping a rectangle from logical to device units.
Converts logical points into device points. The function maps the coordinates of each point from GDI's logical coordinate system into a device coordinate system. The conversion depends on the current mapping mode.
