I am using the 2.3.18 development version of gimp on a SPARC Solaris
system, but I also see this with the 2.2.15 version as well.
I have a 4MB jpeg file created with my Minolta 7D camera. I load it into
Gimp and then immediately save it. The resulting file is now only 482kB
in size! When I use exiftool to examine the exif data, I see the following
unexpected changes:
Original Version Saved Version
--------------------- ---------------------
File Size: 4 MB 482kB
X Resolution: 72 300
Y Resolution: 72 300
Minolta Image Size: Large Medium
Focus Mode: Manual Single-Shot AF
ISO Setting: Auto 800
Free Mem. Card Images: 300 1
Rotation: Horizontal (normal) Unknown (0)
Image Number: 3 4
Image Number 2: 5523 3
The saved version also reports:
Warning : [minor] Possibly incorrect maker notes offsets (fix by -94?)
It appears that the development version of gimp is messing up the exif header
in a number of ways. But why is the file being truncated to such a degree?
Is there something I have set incorrectly that is causing this? Is there
a preference setting for a default level of jpeg compression? In both
cases the image size is being reported as 3008x2000 but note the difference
in the DPI resolution. I feel as though I must be missing something
obvious. Thanks for any pointers you can offer.
Regards,
