pointer to a vector handle |
L_HMETAFILE hWMF; |
handle to the WMF to be converted |
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.
Parameter |
Description |
hDC |
Handle to the device context responsible for the conversion. |
pVector |
Pointer to the vector handle to be updated with the converted file. |
hWMF |
Handle to the WMF to be converted. |
SUCCESS |
The function was successful. |
< 1 |
An error occurred. Refer to Return Codes. |
This function updates information in the vector handle and copies the WMF drawing data into the LEAD bitmap.
