virtual L_INT LVectorBase::ConvertFromEMF(hDC, hEMF)
HDC hDC; |
/* handle to a device context */ |
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.
