If the file has one sample per pixel and is of type float (4 bytes per pixel, sampleformat ieeefloat) then you would do something like this:

      buf = _TIFFmalloc(TIFFScanlineSize(Tif));
      for (int row = 0; row < ImageHeight; row++){
        TIFFReadScanline(Tif, buf, row);
        "reading the buff somehow";
        for( int pixel = 0; pixel < ImageWidth; pixel++ ) {
           printf( "value[%d,%d] = %f\n",
                   pixel, row, ((float *) buf)[pixel] );
        }
      }

Thanx,but what due to my inspect the TIFFTAG_SAMPLESPERPIXEL tag sais that my file has 1076232193 samplesperpixel.What does that mean??? Just to be correct:

int samplesperpixel;
TIFFGetField(Tif, TIFFTAG_SAMPLESPERPIXEL, &samplesperpixel);
cout << samplesperpixel << endl;

was the code.
