OpenSeadragon: Check if Image is Rotated
OpenSeadragon is a powerful JavaScript library that allows you to display high-resolution images in a web browser. It's especially popular for applications in digital museums, art galleries, and any use case that requires detailed views of images. One common challenge users may encounter is determining whether an image has been rotated. In this blog post, we’ll explore how to check if an image displayed in OpenSeadragon is rotated. When working with images, particularly those captured by smartphones or digital cameras, it's essential to understand that they may store orientation information within their metadata. This means that even if an image appears upright in a viewer, it could be technically rotated based on its metadata. OpenSeadragon doesn't automatically adjust the orientation of images based on their metadata, so you’ll need to handle this manually.
