[ANN] Exif

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

Disclaimer:

This software is provided as is. It is in a very early stage and there 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 up before. I refuse any responsibility for any data lost while using this software.

Thanks. It should work also in Pharo.now.
