This image has EXIF
"Orientation":{"val":"Top-left","type":3}
, we know its EXIF is obvious wrong, but it should rotate and lay down.
I use newest ImageMagick running:
Code: Select all
convert auto-orient-bug.jpg -auto-orient output.jpg
the output image is same as the origin.
My question is how ImageMagick dectect this and keep the image standing.

I can confirm this is a bug in ImageMagick and it will be fixed in 6.8.8-2.

The image will be rotated 90 degrees with -auto-orient in the latest beta.
