There are few things ate my time:

  • jpeg file format variations
  • jfif vs exif

So, in order to make any changes to EXIF data (APP1 segment) the following solution is applicable:

  • read out the whole file (just map it)
  • find out required section for EXIF
  • do the changes
  • write out all the data back, segment by segment

nor libexif nor libjpeg doesn't provide such thing. also misc information and image data itself are not page size aligned.
