[digiKam-users] More on changing image resolution

[Northern Colorado Event Photograph]

Yes, I understand that ". . . a digital image doesn't have an intrinsic
size in inches, only a size in pixels."

And I also understand that "Resolution plays a role when printing . . . ."

But that is my point.

Suppose you are processing (for example) a low res JPG image out of a smart
phone,  And you have a request for a print (4 x 6 or 5 x 7).

To provide a satisfactory print, it may make sense to increase the
resolution of this image.  Yes, I understand that this is not usually a
good idea and can potentially result in a number of issues with the final
product.

Nevertheless, it is worth a try, if for no other reason that to make the
requestor (customer/client) happy.

Now 300 ppi doesn't make sense in this case, but 120 or 150 might.

Unfortunately, if I correctly understand the messages in this thread, there
is no way in digiKam to make this change independent of changing the
dimensions (resizing) of the image.

BTW, FWIW, here a number of links to articles that can help both amateurs
and professionals obtain a better understanding of this topic:
