LVectorBase::ConvertFromWMF

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 Pro Toolkit.

Syntax

virtual L_INT LVectorBase::ConvertFromWMF(hdc, hWMF)

Parameters

HDC hdc

Handle to the device context responsible for the conversion.

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.
