> Does anyone not use JPEG because they think the internals of JPEG binary format are a bit complicated? Yes! There are lots of examples like this. • Plenty of small tools write BMP or Targa instead of JPEG or PNG, because these formats are dead simple to reinvent. • JPEG as we know it is JFIF, which has clearly won over alternative JPEG data containers, such as more complicated TIFF (mode 6). BTW JPEG, for what it does, is brilliantly simple. • MNG never took off, but dumber APNG did. Formats that are intended for interoperability need multiple implementations, and it does happen that authors say "no, fuck that" and choose a different format instead.
