PIL question: keeping metadata

[Ivan Herman]

A question on using the PIL library. If I take a jpg file then, say, resize it and save it
somewhere else, all metadata that is part of the jpg file is lost. This is a pity: digital
cameras routinely add metainformation, so does, for example, Photoshop.

Is there any way of keeping this info in PIL? Alternatively, is there a simple image
processing package that does it?

I don't think so... when I investigated in the past, I think I
discovered that the PIL can't write EXIF data (I might be wrong,
though, or my information might be outdated).

processing package that does it?

Try jpegtran:

There is this:

It would be nice to have general EXIF module, the one that is able to
read and write image metadata. Consider such case: you want to rotate
some image from digital camera, but don't want to remove completely the
whole EXIF metadata -- modifying one field would be sufficient.
