pg has asked for the wisdom of the Perl Monks concerning the following question:

I bought a Kodak digital camera recently, but the editing software came with it has some bugs.

For example, one problem is that, whenever I crop a picture, the date on the picture is gone.

So I am thinking of do something myself. I am not interested in the "image", but I am really interested in the header info, which contains the date, etc.

Does any one know whether there is a Perl module for this? Or maybe you even tried one?

If not, maybe you can point me to some document, and I can do something from scrach. If I get the format, I can do whatever I want.
