[Bug 188323] New: EXIF photograph information is lost after image transformations

https://bugs.kde.org/show_bug.cgi?id=188323

           Summary: EXIF photograph information is lost after image
                    transformations
           Product: digikam
           Version: 0.9.4
          Platform: Debian stable
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: digikam-devel@...
        ReportedBy: itay4bugsonly@...


Version:           0.9.4 (using KDE 3.5.9)
OS:                Linux
Installed from:    Debian stable Packages


1.
The EXIF photograph information, as well as the makernote information, are lost
after transforming a photo.  (Tested on rotating, resizing, and solarizing.)

2.
In parallel, after starting digikam, my terminal gets cluttered with warning
such as this

<output>
Warning: Size 5291 of Exif.Nikon3.0x0091 exceeds 4096 bytes limit. Not decoded.
</output>

This reminds debian bug report #475489.

3.
Images come from Nikon D300, and were saved as the largest tiff possible by the
camera settings.  Image size ~40Mb

Please let me know what other information is needed.

Thanks,
Itay

The image information in EXIF (Date and Time, Manufacturer, Model) seem to
survive the transformation.

I am trying to install 0.9.5 from source.

Configure bailed:
<output>
checking for X... configure: error: Can't find X includes. Please check your
installation and add the correct paths!
</output>

I am trying to figure out where are those includes.
This is debian stable (lenny)

Ubuntu 9.10 libexiv2 0.18.2
What is strange. I creates png with aid of Batch Raw Converter. And I can see
exif info in tab "Properties" and in tab "Metadata". But after editing (or
after creating png with aid of Editor) exif exist in tab "Properties" but
absent in tab "Metadata".
