LVectorBase::ConvertFromEMF

Summary

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 Toolkit.

Syntax

virtual L_INT LVectorBase::ConvertFromEMF(hdc, hEMF)

Parameters

HDC hdc

Handle to the device context responsible for the conversion.

HENHMETAFILE hEMF

Handle to the EMF to be converted.
