I have a multipage tiff, using the c++ classlib lead tools and attempting to save like so:

string sFilePath = "c:\\temp.tif";
LBitmapbase* mybmp = remote->GetLBitmap(); // GetLBitmap returns a valid Bitmapbase ptr

L_INT LRet = mybmp->Save(const_cast<L_TCHAR*>(sFilePath.c_str()),FILE_TIF,0,0,2,-1);

LRet returns as -1002 every time.  I'm at a loss as to what could be causing my problems.  Does it matter what the input file's format was that was used to create the LBitmapBase?  Is there something else going on here?  I'm using Lead Tools 14....

Error number -1002 means invalid parameter(s) passed (please refer to the "Return Codes" topic in the LEADTOOLS C++ Class Library documentation). If you checked the LBitmapBase::Save method in the documentation, you will notice that the save function takes the following parameters:
>> BitmapBase.Save(pszFile, nFormat, nBitsPerPixel, nQFactor, nPageNumber, uFlags, pSaveOptions)
Now, you are trying to save TIFF files as follows:
>> mybmp->Save(const_cast<L_TCHAR*>(sFilePath.c_str()),FILE_TIF,0,0,2,-1);
pszFile = const_cast<L_TCHAR*>(sFilePath.c_str())
nFormat= FILE_TIF
nBitsPerPixel = 0
nQFactor = 0
nPageNumber = 2
uFlags = 2 (SAVE_REPLACE)
pSaveOptions = -1 (this is wrong. You can't pass -1 to the pSaveOptions parameter).

To resolve the problem, try to pass NULL to the pSaveOptions parameter and retry this issue.
