L_VecConvertFromWMF

Summary

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

Syntax

#include "ltvkrn.h"

L_LVKRN_API L_INT L_VecConvertFromWMF(hDC, pVector, hWMF)

Parameters

L_HDC hDC

Handle to the device context responsible for the conversion.

pVECTORHANDLE pVector

Pointer to the vector handle to be updated with the converted file.

L_HMETAFILE hWMF

Handle to the WMF to be converted.

Returns

Value	Meaning
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 WMF drawing data into the LEAD bitmap.

Example

This example converts a windows metafile into a DXF file.

L_INT VecConvertFromWMFExample( 
   HWND hWnd, 
   L_TCHAR* pszFileName, 
   HMETAFILE hWMF) 
{ 
   L_INT nRet; 
   VECTORHANDLE TmpVector;     /* Vector handle for initial conversion */ 
   HDC hDC; 
 
   /* Convert to LEAD vector */ 
   hDC = GetDC( hWnd ); 
   nRet = L_VecConvertFromWMF(hDC, &TmpVector, hWMF ); 
   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;
