LVectorBase::LogicalToPhysical

#include "ltwrappr.h"

virtual L_INT LVectorBase::LogicalToPhysical(pDst, pSrc)

POINT L_FAR *pDst;	/* 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.

Example

L_VOID Example15(HWND hWnd)
{
   //This example will obtains drawing physical extents
   VECTORPOINT LeftTop, RightBottom;
   POINT LeftTop2D, RightBottom2D;
   LVectorBase Vector;

   Vector.Load(TEXT("s:\\temp\\images\\dxf\\test.dxf"));

   // Get drawing logical extents
   Vector.GetObjectParallelogram(NULL, FALSE, &LeftTop, &RightBottom );

   // Convert to physical to get the rect where the drawing will be painted
   Vector.LogicalToPhysical(&LeftTop2D, &LeftTop );
