(Newbie Question) 95.99 pixels/inch -- 299.99 ppi or dpi

[HenryH]

When i start a new image,  it is  96.00 pixels/inch  , but later  i see it as   95.99 pixels/inch --  

 

------------  i think...  i used to "correct" it  back to  96.00 pixels/inch 

 

                        (i also see  299.99 ppi or dpi)  

 

      All this reminds me of the joke  [How do you keep a dummy (newbie) in suspense?]

Assuming you're saving PNG files, they're not required to have any DPI information at all.

 

Paint.net does add an optional header, but that header is metric and integer, stored as pixels per meter. The closest value to 96 DPI becomes 3778 pixels/meter and converting that back to DPI upon loading that file gets you 95.96.

 

Since DPI is only an informational value for printing etc., it has absolutely no effect on the actual resolution of the image saved or loaded.
