Thanks,

return value of TIFFWriteEncodedStrip is 3725568

XSIZE 1728
YSIZE 2156

I usually obtain a black image. (?????????????????)

(I work on Windows XP)

Thank you for help

My code is:

HBITMAP hImage = (HBITMAP)LoadImage(NULL, "C:\\test001.bmp", IMAGE_BITMAP, 
      0, 0, LR_LOADFROMFILE|LR_DEFAULTSIZE|LR_CREATEDIBSECTION); 

CBitmap* m_Bitmap = CBitmap::FromHandle(hImage); 
BYTE* buffer=(BYTE*)GlobalAlloc(GPTR, XSIZE * YSIZE); 
DWORD ret = m_Bitmap->GetBitmapBits(XSIZE * YSIZE , buffer); 

out = TIFFOpen("C:\\out.tif", "w"); 
 if (!out)  return; 


TIFFSetField(out, TIFFTAG_IMAGEWIDTH, XSIZE); TIFFSetField(out,
TIFFTAG_IMAGELENGTH, YSIZE); TIFFSetField(out, TIFFTAG_BITSPERSAMPLE, 1);
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); 

uint32 ret = TIFFWriteEncodedStrip(out, 0, buffer, XSIZE * YSIZE); 

 TIFFClose(out); 
GlobalFree(buffer);
