LVectorBase::LogicalToPhysical
#include "ltwrappr.h"
virtual L_INT LVectorBase::LogicalToPhysical(pDst, pSrc)
/* pointer to a POINT structure */ | |
const pVECTORPOINT pSrc; |
/* pointer to a VECTORPOINT structure */ |
Converts a 3D VECTORPOINT into a Windows 2D POINT.
Parameter |
Description |
pDst |
Pointer to a POINT structure to be updated with the physical 2 dimensional point converted from the 3 dimensional vector point in pSrc. |
pSrc |
Pointer to a VECTRPOINT structure that contains a 3 dimensional point to be converted into a 2 dimensional point. |
Returns
SUCCESS |
The function was successful. |
< 1 |
An error occurred. Refer to Return Codes. |
Comments
Converts a given logical point in the vector drawing (with X, Y, Z coordinates), into a physical 2D point.
Conversion will be based on the current view port and camera set in the VECTORHANDLE.
Not supported in DirectX.
