Hi everyone
again
I have an issue with the OSD. I updated to the new 2.0 version but no luck.
On the website I am using legacyimage pyramid as I said
We uploaded some big jpg-s for zoom view
it works fine everywhere (android devises (galaxy s 5) ) and desktop browsers.
It doesn't work however on iphone 6
OSD launches, no errors in the console
nothing
and it is blank
I can see the boundaries I run the debug mode.
I tried with older and smaller images and it was working there
So I concluded that this has something to do with the image size. Here is what my tests lead to.
235 016 bytes image -> yes
235 823 bytes image -> yes
235 857 bytes image -> no
235 993 bytes image -> no
Any ideas why it stops working on Iphone 6 at this point on?

It has nothing to do with size actually but with the number of the pixels :(

@pgpetrov Yes, unfortunately. Here is more discussion: openseadragon/openseadragon#381
Can you break your largest images into tiles?
