Is there someone who can give me a complete sample

using TIFFTAG_COMPRESSION = COMPRESSION_CCITTFAX4
And TIFFTAG_FAXMODE = FAXMODE_CLASSF
And TIFFTAG_FILLORDER = FILLORDER_LSB2MSB

The source file is bmp or tiff

The output file should be like this:

SubFileType (1 Long): Zero
ImageWidth (1 Short): 1728
ImageLength (1 Short): 2156
BitsPerSample (1 Short): 1
Compression (1 Short): Group 4 Fax (aka CCITT FAX4)
Photometric (1 Short): MinIsWhite
FillOrder (1 Short): Lsb2Msb
StripOffsets (1 Long): 324
Orientation (1 Short): TopLeft
SamplesPerPixel (1 Short): 1
RowsPerStrip (1 Short): 2156
StripByteCounts (1 Long): 45832
XResolution (1 Rational): 204
YResolution (1 Rational): 196
PlanarConfig (1 Short): Contig
Group3Options (1 Long): 0
Group4Options (1 Long): 0
ResolutionUnit (1 Short): Inch
PageNumber (2 Short): 0, 1
Software (22 ASCII): AAAAA
DateTime (20 ASCII): 2004:12:23 10:17:19

I use this code but I usually obtain a black image with nothing else, where is the error?

(If I use FILLORDER_MSB2LSB I obtain a correct image but usually inversed Even with PHOTOMETRIC_MINISBLACK or PHOTOMETRIC_MINISWHITE)
