iPad Image Viewing Problem...

Marky · 28 Mar 2012 at 23:09

Hey all,

I've been using the iPad for a little while, getting used to its bits and bobs

One thing I've found is viewing images on the thing...

For example...

I was trying to view this image courtesy of Reddit. As you can see (as long as you're viewing on a computer) you can view the text quite clearly.

However, on the iPad it looked like this. The text is unreadable on the iPad... It's the same on my iPhone - it must be a resolution thing :/

Any ideas?

Marky

PS - I do know about AlienBlue, and have it on my iPhone but haven't got round to checking it out on the iPad just yet

What Internet connection are you using? I know when I use the mobile Internet from O2, it uses image compression on all images, which degrades the quality like so.

At the time I was using wifi so I don't think it could have been a connection problem - I'll try it again tonight but I'll try it right close to the router to ensure a good connection...

New iPad? maybe something to do with the higher resolution screen and low res images?

Does the same thing on my iPhone 4 on a JANET wifi connection, something the iOS Safari browser does perhaps?

Yes this is what I suspect, but I was wondering if there was any way around it

I can view it fine on a normal computer, but not on the iPad.

Hmm maybe...

Just tested it on an original iPad and the text is still the same on the image, so it's not retina related.

Just an iOS quirk it seems?

Ahh right... I guess so

Thanks a lot for checking and putting my mind to rest

Mobile Safari will downsize a jpg that is over 2.09MP (actually 2x1024x1024 pixels = 2097152). See here

Note that the image is 1046x2760 in Safari, but in your screenshot Mobile Safari has scaled it down to 523x1380.

Aaahhhh! You've cracked it ol' bean

Okay... so this is a bug I assume? Or at the very least a limit which is too tight really

Do you know if there is a jailbreak fix? (I know there isn't a jailbreak out for the new iPad at the moment, but it'd be nice to fix this on my iPhone also!

)

Since this interferes with the full use of the Retina display and Apple’s own published WebKit iOS resource limits state that the maximum size for canvas elements is 5 megapixels on devices with 256MB or more of RAM, I can’t imagine what we’re seeing is anything except an oops that fell through the cracks.

So, chances are that the Mobile Safari (nee Webkit) team weren't told about the new retina display iPads until we were, so it's just an old limit that is now a bit "too tight"

I wouldn't think that a jailbreak solution would be needed, chances are the Mobile Safari guys are working on it right now. Thing is, it'll have to wait for the next point release of iOS as Mobile Safari is baked into the OS. Wouldn't surprise me if an iOS 5.1.1 dropped in the next few weeks.
