iPad 3 , OSX FM11A v4

 

Yes existing layouts are rendered quite well, but optimising for iPad is unavoidable. To this end:

 

Exploring basic file setup and layouts for iPad 3

Using a simple script to evaulate screen parameters and dispaly on layout as a $$var (with a flush) as below

The layout has a bounding rectangle (2048 x 1,536 px) to visually identify the margins.

On the iMac all is normal as per the intial paramater values

The same file native on or shared to the iPad 3 returns very diferent values

 

 

iMac27:

System platform: 1

System version: 10.6.8

 

Screen width: 2560

Screen height: 1440

 

Window desktop width: 2560

Window desktop height: 1418

 

Window width: 2063

Window height: 1418

 

Window content width: 2048

Window content height: 1298

 

Window zoom: 100

 

 

 

iPad 3, same layout values:

System platform: 3

System version: 5.1

 

Screen width: 320

Screen height: 480

 

Window desktop width: 320

Window desktop height: 480

 

Window width: 320

Window height: 480

 

Window content width: 480

Window content height: 286

 

Window zoom: 100

 

 

the iPad 3 display is specified as 2048-by-1536-pixel resolution at 264 pixels per inch (ppi)

I expected some finessing re allowing for top and bottom 'bars', and obviously the usable screen content WxH is reduced by the black border... But I can't find anything to suggested why the results are so far of the expected.

 

I am obviously missing something fundamental. But what?
