- READ TIFF
- Load the TIFF data from the file into memory. Return
- a pointer to a valid DIB (or NULL for errors).
- Uses the TIFFRGBA interface to libtiff.lib to convert
- most file formats to a useable form. We just keep the 32 bit
- form of the data to display, rather than optimizing for the
- display.
-
- Main entry points:
-
- int ChkTIFF ( LPCTSTR lpszPath )
- PVOID ReadTIFF ( LPCTSTR lpszPath )
-
- RETURN
- A valid DIB pointer for success; NULL for failure.
