Hi,
When I am taking picture using a Canon 80D face down, most of the image converted by libraw (current master branch as Sep/26/2016) look kind of scattered and messed up. If I take picture while taking camera horizontally, all the images are OK. I have attached a converted one by libraw. Please let me know how I can send you the raw file since it has the right image in it.

Thanks for the quick reply.
Thanks for the quick reply. dcraw_emu converts the image properly. Now I can see where the problem is. The image has been rotated by camera but I am processing it as if it's in landscape position.
Same result: tested with up
Same result: tested with up-to-date libraw's dcraw_emu without problem.
Do you use your own code with LibRaw or use libraw samples to test?

I wonder is there any way
I wonder is there any way that I can get the rotation information using the API?
imgdata.sizes.flip contains
imgdata.sizes.flip contains rotation information got from file
imgdata.params.user_flip - rotation, forced by user
Both are in same format: 0=none, 3=180, 5=90CCW, 6=90CW
libraw_processed_image_t (result from ..mem_image() calls) contains height/with of (rotated) image.
