so the result is like I display the lines in the reverse order (from bottom to top, and not from top to bottom)

man TIFFRGBAImageGet says:

"(Note that the raster is assume to be organized such that the pixel at location (x,y) is raster[y*width+x]; with the raster origin in the lower-left hand corner.)"

So TIFFRGBAImageGet will always reorient the image and it does it the "windows bitmap" way.
