Is your feature request related to a problem? Please describe.
I need to display images that have separate rotation information, but there doesn't seem to be a way to set a rotation before an image is viewed.
E. g. I have an image that needs to be displayed with a 90° rotation.

Describe the solution you'd like
Allow setting the rotation in the view handler.

Describe alternatives you've considered
Allow configuring a rotation with the image.

How about this solution?

new Viewer(image, {
  // ...
  viewed: function () {
    this.viewer.rotate(90);
  },
});

Thanks for your time.

Your example will show the image, then rotate it. I'm looking for a solution that will show the image as if it is not rotated.

Maybe it is not supported.
