L_VecConvertFromWMF

#include "ltvkrn.h"

L_LVKRN_API L_INT L_VecConvertFromWMF(hDC, pVector, hWMF)

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 Pro Toolkit.

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

Comments

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