The 'none' image orientation option was temporarily deprecated (in 2022) according to HTML specification with the remark about going to be reused with a different meaning in future as the same semantics as CSS 'none' image-orientation. https://html.spec.whatwg.org/multipage/#dom-imagebitmapoptions-imageorientation-none https://www.w3.org/TR/css-images-3/#valdef-image-orientation-none Official MDN documentation added it back with new meaning (in 2024), but it wasn't added back to HTML specification (still pending). https://developer.mozilla.org/en-US/docs/Web/API/Window/createImageBitmap#none At current moment this option is poor supported on all major browsers, but there are some existed WPT tests (ImageBitmap/WebGL) which are actively use it in createImageBitmap() options. Chromium (supported): - stable: same as 'from-image' (but with deprecation warning) - experimental: ignoring any orientation metadata Firefox (supported as default option): - stable: ignoring any orientation metadata ('from-image' do the same) Testing: Improvements and fails (expects 'from-image' behaviour from 'none' option) in the following tests - html/canvas/element/manual/imagebitmap/createImageBitmap-exif-orientation_none.html - webgl/tests/conformance/textures/misc/exif-orientation.html Fixes (partialy): #34112 Signed-off-by: Andrei Volykhin <andrei.volykhin@gmail.com>
