Size of written JPEG file differs #7

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago

When the JPEG writer parses an Exif file and writes it again to disk
without changes, the sizes of the two files differ.
If Exif rewriting is disabled, the file grows 2 bytes in size. If it is
enabled, it shrinks 8823 bytes.
There does not seem to be a problem with the parsing of the file by image
viewers or Exiftool.

The test image is included.

The two bytes have been found, see issue 31.
The rest is probably due to a missing thumbnail, and possibly a different 
coding of
data in the Exif structure.
