After some conversion (the decoder will always produce 16 bit signed output, but 8 bit unsigned image data is needed), a raw image
If you followed my works, you know that I like compact, single-file implementations of decoders for various media formats, and where such a thing doesn’t exist, I tend to write or at least port one myself. Now I’d like to add the third format to that list: Baseline JPEG images. There are already two decoders on the web that go by the name »Tiny JPEG Decoder«: One of them actually isn’t tiny at all
