How can I use FillOrder=Lsb2ToMsb, TIFFTAG_COMPRESSION =
COMPRESSION_CCITTFAX4?

Usually I obtain a black image.
 

My code is :

TIFFSetField(out, TIFFTAG_IMAGEWIDTH, XSIZE);
TIFFSetField(out, TIFFTAG_IMAGELENGTH, YSIZE);
TIFFSetField(out, TIFFTAG_BITSPERSAMPLE, 2);
TIFFSetField(out, TIFFTAG_SAMPLESPERPIXEL, 1);
TIFFSetField(out, TIFFTAG_ROWSPERSTRIP, YSIZE);
TIFFSetField(out, TIFFTAG_SUBFILETYPE, 0);
 
TIFFSetField(out, TIFFTAG_COMPRESSION, COMPRESSION_CCITTFAX4);
TIFFSetField(out, TIFFTAG_GROUP4OPTIONS, 0);
TIFFSetField(out, TIFFTAG_FAXMODE, FAXMODE_CLASSF);
TIFFSetField(out, TIFFTAG_PHOTOMETRIC, PHOTOMETRIC_MINISWHITE);
TIFFSetField(out, TIFFTAG_PLANARCONFIG, PLANARCONFIG_CONTIG);
TIFFSetField(out, TIFFTAG_FILLORDER, FILLORDER_LSB2MSB);
 
TIFFSetField(out, TIFFTAG_ORIENTATION, ORIENTATION_TOPLEFT);
TIFFSetField(out, TIFFTAG_RESOLUTIONUNIT, RESUNIT_INCH);
TIFFSetField(out, TIFFTAG_XRESOLUTION, 204.0);
TIFFSetField(out, TIFFTAG_YRESOLUTION, 196.0);
TIFFSetField(out, TIFFTAG_DATETIME, "2004:12:23 10:17:19");
TIFFSetField(out, TIFFTAG_SOFTWARE, "Jamel");
TIFFSetField(out, TIFFTAG_PAGENUMBER, 0, 1);
 
TIFFWriteEncodedStrip(out, 0, buffer, XSIZE * YSIZE);
TIFFWriteDirectory(out);
