Prevent wrong orientation from EXIF data with Thumbor filters

When I access an image with orientation EXIF data, the output is often automatically rotated to an incorrect orientation. This seems to be a common issue: https://github.com/awslabs/serverless-image-handler/issues/220, https://github.com/awslabs/serverless-image-handler/issues/25

The current solution seems to be to include "rotate": null in the edits list. However, I’d prefer to access images using the Thumbor filters, so directly modifying the edit list isn’t possible. Using a null value in the rotate Thumbor filter also doesn’t look like it’s possible.

A previous solution was to modify the RESPECT_ORIENTATION config value, however this doesn’t look like it’s supported using Sharp.

I saw that Sharp supports a PRESERVE_EXIF_INFO config value. I tried to override this by setting a Lambda environment variable of the same name to True, but this didn’t have any effect. Perhaps this isn’t the right way to set the config value.

Any ideas would be greatly appreciated! It seems like this should just be the default behaviour…

Hello, I still have the bug on my cloudfront… are you sure the bug is fixed ? thanks

@avario I’m trying to experiment withMetadata() but it’s not working properly when I provided rotate value. I’ll update once I find the permanent resolution of this issue.
