PIL: retreive image resolution (dpi)

Hi, I looked at the PIL Image class but cannot see a posibility to retreive the image resolution dots per inch (or pixels per inch) Could somebody please tell me how to get these metadata infos in PIL? thanks, Alex. -- http://mail.python.org/mailman/listinfo/python-list

Hi ! The size of a image is an element ; but resolution is another. It is the link, between the image and the reality. Size AND resolution can to give the scale. Exemple : when you scan a document, the size (in pixels) is not sufficient, for to reproduce the document. Size + resolution, yes.
