title: Scaling ratio of two different resolutions
body: <p>I have two different resolutions, the original one is 567x756 (wXh), the one which I want to display is 768x1024 (wXh). How to find out the scaling ratio for these two resolutions? For example if the font size used in 567x756 resolution is 7 pts then what's the values I should multiply with the font size (7 pts) to display the text in 768x1024 resolution.</p>
