Exif Orientation Info in Pngs Isn't Used for Image-Orientation: From-Image

Regulars are buzzing about a bug report revealing that EXIF orientation info in PNGs is ignored for image orientation, sparking a lively debate about image processing and metadata standards. Commenters riff on the inconsistencies between image formats, with some pointing out that PNGs don't actually support EXIF data, while others argue that many image viewers and editors still interpret it. As the discussion unfolds, a surprising insight emerges: despite the spec, many tools have converged on supporting EXIF-like metadata in PNGs, blurring the lines between formats. The thread feels relevant right now because it highlights the messy, evolving landscape of image processing and the challenges of maintaining compatibility across different formats and implementations.
