Hi!

I just uploaded a first hack of an Exif package to squeaksource.

http://www.squeaksource.com/Exif.html

MIT License. Any contributions are welcome (see current limitations).
Haven't tested it on Pharo yet. But there shouldn't be anything special
about it.

Have fun,
 Alex

>From the project description:

This provides code to extract/modify the Exif (Exchangeable image file
format) information from/inside media files.

   - Current limitations:
   - Works only for TIFF-, JPEG-files
      - Can't write Exif information
      - Can't read/write GPS information
      - Can't read/write Interoperability information
      - Can't read/write any vendor specific MakerNote
      - Can't read/write UserComments
      - Most methods for cooked information (like dateTime) are missing

   - Examples:
   "Dump all Exif information from a JPEG-file to the Transcript"
   Transcript show: (Exif readFromJPEGNamed: 'p2.jpg') printAll; cr.

   "Get *raw* Exif content for DateTime (a String)"
   (Exif readFromJPEGNamed: 'p2.jpg') atTagName: #DateTime. "#('2010:11:10
   16:56:33')"

   "Get *cooked* Exif content for DateTime (a DateAndTime object)"
   (Exif readFromJPEGNamed: 'p2.jpg') dateTime. "2010-11-10T16:56:33+01:00"

   - Specs:
   Exif and TIFF <http://www.exif.org/specifications.html>

   are no guaranties that the software will work as expected or advertised.
   Be sure to use only image files with this software that you have backed
