EXIF Properties, .Net and Digital Image Library

[gdgass]

Hi,

I'm in the process of developing an app to scan and archive photos
based upon the EXIF/Photo Keyword property. One of the requirements
is
that the Photo's keywords be editable via Digital Image Suite 2006
Library . Then the app will look for a specific keyword, change the
keyword to indicate the photo has been scanned and move a copy to the
archive area.


Here's the problem. I can successfully load a jpeg into an image
object, copy it to another image object, change the properties, save
the copy to a temp file, delete the original and rename the temp file
to the original file name, preserving the image and the keyword
changes.


Using the Explorer File Properties dialog I can verify the keyword
property has been changed, but Digital Image Suite doesn't recognize
the change. In the File Properties Dialog I can change any property,
'Apply' the changes and Digital Image Suite recognizes the changes.


So.....


The app under development can see changes made with either Digital
Image Suite or the File Properties Dialog.


The File Properties Dialog can see the changes made with either
Digital Image Suite or my app.


Digital Image Suite can ONLY see changes made with the File
Properties
Dialog.


Does anyone know what's going on with Digital Image Suite and why it
can't see the changes?


Any help or information on this subject would be greatly appreciated.


Thanks,


Gary

Perhaps it (DIS) is reading only the IPTC data, but writing both IPTC and
EXIF data? If you open the before and after files in a text editor, it
should be quite easy to see what has been changed.
