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

thank you, i know why :)

now, how can I use libtiff to display it correctly? i've tried several things, without success

I meant that this is normal if you use the TIFFRGBA API. You must either reverse the data yourself or get your display toolkit to do it.

You could use a lower level libtiff API but then you'll have to handle the orientation tags yourself so you won't be much better off if you hit a TIFF which is not "top left".
