Hi Helder, thanks for your links, although it is not my case, it helped me to name my problem at least. I've met there keyword Exif orientation. It seems to me that this info is not read from the image (like in IrfanView and other tools) so I am getting not rotated output. Is this Exif info supported? Are even older versions of this specification supported? Image was taken by 5 years old Canon Ixus V3.
Thanks in advance for any feedback.
