Summary

Pull request #31829 added the autorotate operation as first operation sent to imaginary. For svg images, this will fail with the following error messages:

  • using the official h2non/imaginary docker image: Error while processing the image: VIPS cannot save to "svg"
  • using imaginary docker image from the nextcloud aio package: Error while processing the image: Unsupported image output type

As soon as the autorotate operation is removed from the imaginary pipeline, the svg image is correctly resized (fit) and converted to an jpeg image.

This PR skips the autorotate operation if the mime type of the image is:

  • image/svg+xml
    or
  • image/svg

Additional notes

The imaginary pipeline API operation has an option ignore_failure for each operation. If this option is enabled for an operation, that operation should fail silently and the pipeline would continue with the next operation without failing.

Unfortunately that did not work for me.

IMO, this workaround seems a bit hacky. However, SVGs don't have exif metadata so the autorotate step is obsolete anyway.

LGTM!
