Translations:HiDPI support/62/en

To solve the issue, Apple introduced "HiDPI", that is scaling all the UI elements according to the font size. Font sizes are specified in points, while their pixel value is calculated using DPI and device pixel ratio which is a scale factor specified by a user in OS settings. At the same time, raster images are rendered at their true pixel size, so individual pixels are less noticeable. It means that raster images are provided at higher resolution to make up for their size on a screen. Vector graphics (UI elements) are rendered accordingly, at higher resolution.
