L_VecLogicalToPhysical

#include "lvkrn.h"

L_INT EXT_FUNCTION L_VecLogicalToPhysical(pVector, pDst, pSrc)

const pVECTORHANDLE pVector;	/* pointer to a vector handle */
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
pVector	Pointer to a vector handle.
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 OpenGL or DirectX engines.

Example

/* This example will obtain drawing physical extents */

void GetExtents( pVECTORHANDLE pVector, RECT *pExtent )
{
   VECTORPOINT LeftTop, RightBottom;

   /* Get drawing logical extents */
   L_VecGetObjectParallelogram( pVector, NULL, &LeftTop, &RightBottom, 0L );

   /* Convert to physical to get the rect where the drawing will be painted */
   L_VecLogicalToPhysical( pVector, (POINT *) &pExtent->left, &LeftTop );
   L_VecLogicalToPhysical( pVector, (POINT *) &pExtent->right, &RightBottom );
