    uint32 lSize;
    int buffer[100];

  TIFFSetField(image,TIFFTAG_BITSPERSAMPLE, 8);

  TIFFWriteEncodedStrip(image,0,buffer,100);

Zhou,

Your fundamental mistake is using a 32 bit integer buffer 'buffer', when actually writing an 8bit per sample image. Try declaring buffer as "unsigned char buffer[100]" instead. I haven't tried your code so there may be other problems as well.

Best regards,
