I am working with mobile screen resolutions (dpi).
at 320dpi = 640 pixels
at 250dpi = 500 pixels
If I wanted to use the above pattern, how would I calculate to change the dpi value to make it x dpi = 480 pixel ?
Please ask if I am being vague and I will try and explain it further.
I am looking for a formula that finds the difference of how much to divide on each side I suppose.
