Hi All,
I want to change the resolution of the image from 72 to 25 dpi using PHP?
is it possible?

A:
It's not possible (at least with PHP/GD, not sure about ImageMagik), sorry.
However you can try mimicking it, lets say you want to create a 400x300 25 dpi image, here is the math:
WIDTH
72 -------- 400
25 -------- w = (25 * 400) / 72 (=) w ~= 139 pixels
HEIGHT
72 -------- 300
25 -------- h = (25 * 300) / 72 (=) h ~= 104 pixels
You create a new 139x104 72 dpi image, work with it and after you're done resize it to 400x300 pixels.
