The 15.4-inch Retina Display has a native resolution of 2880 x 1800, that’s 2880 pixels across and 1800 pixels down for a total area of 5,184,000 pixels. It’s a bit complicated and confusing so let me try my best to explain what’s going on here in a practical sense. These elements will receive the same linearly interpolated upscale I mentioned above. Bitmapped images are scaled up using linear interpolation, but if higher resolution assets are provided OS X can simply swap and use those on a Retina Display.Īpplications that render vector graphics, text and other elements to their own backing store will need hand tuning to look good on the Retina Display. should all look “normal” sized and just be ridiculously sharp on the Retina Display. Unmodified dialog boxes, toolbars, menus, etc. All vector based graphics and text using Apple’s APIs are automatically scaled up. This aspect of OS X is key to enabling good behavior in applications as you’ll soon see.Īpple does a lot of the display handling for you so you don’t have to think about any of this. The backing scale factor isn’t a global value, it can be set on a per element basis, allowing controls to to be legible while you get the benefits of a higher resolution for additional screen real estate. In the case of the former you get 1:1 point to pixel mapping, while in the latter each point is backed by four pixels. The backing scale factor can either be set to 1.0 or 2.0. How pixels map to points is determined by the backing scale factor. Images are the same size, but made of 4x the number of pixels on Screen 1 compared to Screen 0 Points in OS X are now floating point values, as a single point can be represented by multiple pixels on a high density display. Traditional OS/display combinations had a 1:1 mapping between points and pixels. OS X, similar to iOS, uses points to represent display coordinates. The Software Side of Retina: Making it All Work
