ok so each jpeg file now has to have a set of coordinates that are relative to the image to determine how the image should be shown as a thumbnail neat idea but I want to know how to get it in the latest jpeg spec

exif data actually does let you define a thumbnail + its rotation, if the thumbnail generator uses that data

Absolutely gently caress all software seems to support thumbnails, so  echinopsis posted:can you rotate a jpeg safely In 90° increments, yes.

i presume you decide it to some bit planes, do a few nested for loops and move the pixels around, and re-encode cool thing GIMP used to let you do was let you encode jpegs at arbitrarily low quality. adobe photoshop usually enforces a free-limiting minimum limit to the quality which frankly we didn’t ask for

So basically decoding a couple of layers but not the entire image. Or, just use one of the bajillion apps and libraries that implement it already: http://jpegclub.org/losslessapps.html There's a lot of interesting stuff that can be done in the frequency domain without a full decode, https://arxiv.org/ftp/arxiv/papers/1907/1907.11503.pdf

JPEG already has everything in the standard but nobody knows its there and no software bothers to support it.
