Dear Frank,
Thanks a lot for your reply. As to the image I deal with, the other tag informaiton is:
************
TIFFTAG_SAMPLESPERPIXEL: 3
TIFFTAG_BITSPERSAMPLE:8
TIFFTAG_PLANARCONFIG: PLANARCONFIG_CONTIG
*************
And I read the tile as the following:
*************
# define uint8_T unsigned int
TIFFGetFieldDefaulted(IN_tif, TIFFTAG_SAMPLESPERPIXEL, &spp);
TIFFGetFieldDefaulted(IN_tif, TIFFTAG_BITSPERSAMPLE, &bps);
col=0;
row=0;
if(config==PLANARCONFIG_CONTIG) {
/* Chunky mode - RGBRGBRGB... */
if (bps==8) {
buf_8 = (uint8_T *) malloc(tileSize*sizeof(uint8_T));
if (TIFFReadRGBATile(IN_tif, buf_8,col,row,0,0 )==-1){
exit;}
for (x=0;x<tileLength;x++)
{ position=0;
bufscanline_8= (uint8_T *) malloc(tileWidth*spp*sizeof(uint8_T));
for (y=0;y<tileWidth;y++)
{
bufscanline_8[position]=buf_8[((x+y*tileWidth)*3]);
bufscanline_8[position+1]=buf_8[(x+y*tileWidth)*3+1]);
bufscanline_8[position+2]=buf_8([(x+y*tileWidth)*3+2]);
// printf(" %d \n",bufscanline_8[position]);
position=position+3;
}
TIFFWriteScanline(OUT_tif,bufscanline_8, x, 0);
free(bufscanline_8);
}
free(buf_8);
}
}

Would you please tell me what's wrong with the above code?
Waiting for you kind suggestions eagerly!
