A few examples of use-cases for `createImageBitmap`: - Crop images on-device - Resize images on-device before uploading to a server - For example a photo from `<input type="file" capture="environment">`. - On-device image resize has long been problematic, with the main workaround being the Canvas element, but every implementation I've seen has been buggy or hard to use, for example due to iOS canvas memory limits. - Take snapshots from a video feed - Extract sprites from a sprite sheet - Take non-rotated image pixels with an associated EXIF tag and output rotated pixels (without any EXIF), or put differently strip EXIF and apply rotation to image data. - This is useful since many server-side systems prefer to handle all images without accompanying exif rotation data.
