LAnnEncrypt::GetSecondaryMetafile
#include "ltwrappr.h"
virtual L_INT LAnnEncrypt::GetSecondaryMetafile(phMetafile)
HMETAFILE * phMetafile; |
/* pointer to a variable to be updated with the handle to a metafile */ |
Retrieves the metafile handle associated with an encryptor object when it is in the decryptor state. This function is available in the Document/Medical Toolkits.
Parameter |
Description |
phMetafile |
Pointer to a variable to be updated with the handle to a metafile. |
Returns
SUCCESS |
The function was successful. |
< 1 |
An error occurred. Refer to Return Codes. |
Comments
The encrypt object has two states:
Encryptor
Decryptor
Each state is displayed with its own metafile.
Use this function to retrieve the current metafile for an encrypt object in a decryptor state. The default image is shown in the figure below:
If this function is successful, the address pointed to by phMetafile will be updated with the metafile handle.
Use the LAnnEncrypt::GetMetafile function to retrieve the current metafile for an encrypt object in an encryptor state.
