Expected behaviour

The meta data should report the new dimensions from the rotated image.
(415px x 620px)

Actual behaviour

The meta data reports the dimensions of the image BEFORE it was rotated
(620px x 415px)
When I remove "meta" the image is correctly fitted in and turned correctly. EXIF Information is also correct.

Your thumbor.conf

RESPECT_ORIENTATION=True

Is it my fault? or a bug?

Thank you so much for writing thumbor!

It is a bug, but I'm not sure when I can go and fix it. Any chance you can help with a PR?

[pscheit]

mhh. I'm a real python noob and got no infrastructure to code and test python projects. I would think I would break everything if I'll fix it :D
But the bug isn't affecting my production right now, so let's see who will got time to fix it first.
thanks!

@heynemann do you think you can spend some time on this?

Would you agree, that the meta data for the original of the image (with an exif-Orientation Tag != 1) would still be the physical size of the original image (e.g. not rotated)

And the meta data for a thumbnailed/resized/whatever changed (and exif stripped) image is then rotated, when RESPECT_ORIENTATION=True ?

@pscheit Can you try my solution to see if it solves your problem?

LGTM
