Images looks blurry in iPad when Pinch + zoom #380

Closed kothinti closed 12 years ago

kothinti commented 12 years ago

Hello,

I am using nearly 1350 x 1750 px images. Everything works well except the image clarity (blurry) in iPad when zoomed in (pinch + zoom)... anyone had this kind of issues? and any solution for this?

The something is working fine on Desktop, Nexus 7, G-SIII.

Progressive JPEG images look good on iPad too.

Hi,

This is a known issue with Apple iOS 5 (and older), which due to old resource limits will reduce the size of JPEG images more than 2 megapixels in size. iOS is not able to reduce the size of progressive (interlaced) JPEGs, which is why they still look good on the iPad. In iOS 6 the subsampling threshold will be increased to 5 megapixels, except for on iPhone 3GS and iPod Touch (4th gen). iOS 6 will hopefully be released later this month.

Not a PhotoSwipe issue - closed.
