          Issue ID: 127971
        Issue Type: DEFECT
           Summary: Image Sizing Issues with Adobe PSE 15 and EXIF
           Product: Writer
           Version: 4.1.6
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P5 (lowest)

  Target Milestone: ---

This is perhaps similar to a very OLD issue, 54930
(https://bz.apache.org/ooo/show_bug.cgi?id=54930), which probably no longer
applies since the version is very old.  However, this issue is detailed here:
https://forum.openoffice.org/en/forum/viewtopic.php?f=7&t=96203

Problem:
Writer seems to be using the old JFIF standard which Adobe says is obsolete and
not compatible with EXIF. Adobe uses the EXIF standard only. Using exiftool to
extract the metadata in groups shows that the files which are correctly sized
by Writer include a JFIF group containing resolution data. The files from
Photoshop Elements don't have the JFIF group.

If I use exiftool to change the JFIF resolution but not the EXIF resolution for
a .jpg that is displayed with the correct size, then Writer uses the new JFIF
resolution and the image size changes. If I completely remove the JFIF settings
then Writer uses 96ppi on my system and again the image size changes. In both
cases, Writer ignores the EXIF resolution settings stored in the file.
