Returns
An L_UINT32 value representing the LEADTOOLS libraries that were loaded successfully. This can be any combination of the constants described above.
Comments
Call this function to load a specific set of the LEADTOOLS library DLLs at run-time. The specified constants will determine which libraries you want to load. If the library is already loaded then this function will not load it again. You can use this function to minimize the memory footprint of your program by loading and unloading the libraries you need when necessary.
Note: if you use LT_DLG in the uLibraries parameter without passing any flag in uSubLibraries, all LEAD dialogs will be loaded by default.
Required DLLs and Libraries

Example
The following code will load the LEADTOOLS library for the TWAIN scanner
driver (assuming that ltkrnXXn.dll is already loaded), and scan an image
to a bitmap:
L_INT LBase__LoadLibrariesExample()
{
LTwain MyTWAIN;
LBitmapBase MyBitmap;
if(LBase::LoadLibraries(LT_TWN)& LT_TWN)
{
MyTWAIN.SetBitmap(&MyBitmap);
MyTWAIN.Acquire ((LBitmap*)NULL,0,0,NULL);
LBase::UnloadLibraries(LT_TWN);
}
return SUCCESS;
}
