If you roll in the hay anything about the unexampled iPad , it ’s believably that the third - multiplication model of Apple ’s pill will sport a so - calledRetina display — a screen with pixel concentration so high that the human eye ca n’t pick out the single dots in normal manipulation . Old iPad apps will look fine on the newfangled iPad , but only apps that update with Retina - calibre imagination can fully tap the updated screen . Apple already update almost all of its own apps , and now it ’s updating its website with Retina - ready nontextual matter , too .
AppleInsiderreported Tuesday on some JavaScript slickness you may use to preview a interlingual rendition ofApple ’s websitewith the company ’s Retina imagery . ( Of course , if you ’re using an actual third - contemporaries iPad to visit Apple ’s site , you ’ll see the Retina - friendly alternative automatically . )

The JavaScript code provided by AppleInsider just replaces all the range of a function on Apple ’s website with alternative Retina picture instead . Apple ’s higher - timber images offer a clear exposure of precisely what ’s involved in readying Retina - quick images .
At this writing , Apple ’s home page sport the faux word “ Resolutionary”—text rendered in graphic form — along with an image of a paw touch the new iPad . Before you black market AppleInsider ’s computer code , the nonremittal webpage expend a 471 by 93 pixel for the Resolutionary image , which weighs in at about 7 kb . After you start the codification , Apple fill in a variation of the image that doubles its breadth and height , yielding a 942 by 186 pixel image that count in at about 18 kb .
The heavy iPad graphic starts out much prominent , so its Retina interlingual rendition is , honestly , enormous . The original ikon criterion 1454 by 605 pixel and 113 K ; the Retina version is a banging 2908 by 1210 pel and 360 kb . The Resolutionary image is about 2.5 times orotund in its Retina version , and the handwriting and iPad image is more than 3 time orotund . It ’s those Retina - friendly increased ikon sizing that make me vex about the impending iPad storehouse outer space crush , but in this case the WWW paradigm would n’t bolt up your iPad ’s remaining place . Those images could , however , gobble up plenty of extra bandwidth — which could be quite pregnant if you ’re using your new iPad ’s cellular connection .
The original image is shown at the left; the one on the right shows a section of the doubly large Retina version.

When Apple ’s website load those larger Retina effigy , it still twinge them into the quad adopt by the smaller versions . That is , the 2908 pixel extensive iPad image is only display by default on the iPad as 1454 pixels wide . The doubling of the mental image empower the Retina display to exercise its optic magic .
