PIL: retreive image resolution (dpi)

[Do Re Mi chel La Si Do]

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.
