Oops.
Thank you.
I was on Apple Tech Specs page for the iPhone 5 on the Internet (
https://support.apple.com/kb/SP655?locale=en_US ) , looking for screen size and resolution and I found: 4" Retina display ; 1136-by-640-pixel resolution at 326 ppi
Similarly, I looked on other iPhone pages for screen sizes and resolutions and I found:
iPhone 3GS (at this moment, no more present on Apple site) = 3.5" / 480 x 320
iPhone 4 and 4S = 3.5" / 960 x 640
iPhone 5 , 5S and SE = 4" / 1136 x 640
iPhone 6 = 4.7" / 1334 x 750
iPhone 6+ = 5.5" / 1920 x 1080
Now, when I take a screenshot from a running App on my iPhone5, I get a png file with dimensions 1136 x 640, that's the resolution of the screen.
On Apple sites, I haven't found informations about "normalized layout" and "scale factor" ; can you provide a link to a table with such informations ?
Also, using the program
B4i-Resizer, found on this forum, I got some strange resolutions, converting my original 1136x640 screenshots.
The resulting images have this format:
3.5" -> 960 x 600 (note:
600, not 640)
4" -> 1136 x 600 (note:
600, not 640)
4.7" -> 1334 x 750
5.5" -> 2208 x 1242 (expected: 1920 x 1080)
ipad -> 1024 x 768 (not checked on Apple site)
iPadPro -> 2732 x 2048 (not checked on Apple site)
Would you, please, help me to understand what is true and what false ?
Those strange values are driving me mad...
Thank you in advance.
