Glad I got assigned!

JPEG Header Viewer W3 documentation about JPEG (?)

How I see the next stage:

  1. Read JPEG the way we do it in stage 1 (put raw pixel data into canvas),
  2. Re-encode new JPEG into memory (we need some particular jpeg encoder settings for it to be easier, mainly: not progressive and using Baseline DCT),
  3. Read JPEG, find SOS - (Start of scan header) and edit it acording to our needs,
  4. Present edited file to the user.
