L_VecConvertFromEMF

#include "lvkrn.h"

L_LVKRN_API L_INT L_VecConvertFromEMF(hDC, pVector, hEMF)

L_HDC hDC;	/* handle to a device context */
pVECTORHANDLE pVector;	/* pointer to a vector handle */
L_HENHMETAFILE hEMF;	/* handle to the metafile to be converted */

Converts an enhanced Windows metafile (EMF) into a LEAD Technologies vector handle. When this function is completed, there are two copies of the drawing in memory: the EMF and the original LEAD vector. Freeing one will not affect the other. This function is available in the LEADTOOLS Vector Imaging Pro Toolkit.

Parameter	Description
hDC	Handle to the device context responsible for the conversion.
pVector	Pointer to a vector handle.
hEMF	Handle to the EMF to be converted.

Returns

SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.

Comments

This function updates information in the vector handle and copies the EMF drawing data into the LEAD bitmap.

Example

This example converts an enhanced windows metafile into a DXF file.

L_INT VecConvertFromEMFExample(
   HWND hWnd,
   L_TCHAR* pszFileName,
   HENHMETAFILE hEMF)
{
   L_INT nRet;
   VECTORHANDLE TmpVector;     /* Vector handle for initial conversion */
   HDC hDC;

   /* Convert to LEAD vector */
   hDC = GetDC( hWnd );
   nRet = L_VecConvertFromEMF( hDC, &TmpVector, hEMF );
   if(nRet != SUCCESS)
      return nRet;

   ReleaseDC( hWnd, hDC );

   /* Save as DXF */
   nRet = L_VecSaveFile( pszFileName, &TmpVector, FILE_DXF, NULL );
   if(nRet != SUCCESS)
      return nRet;

   /* Free the vector */
   nRet = L_VecFree( &TmpVector );

   return nRet;
