Scrolling a very large image on iOS

Hi Gerry,

It’s not a memory problem; it’s a size {as in pixels} problem.
All livecode objects have a 32k pixel size limit.
If an object {especially the groups} exceeds this limit, scrolling gets totally erratic.

You can test it by temporarily resizing your image to 30k pixel.
It’ll work without a problem.
Increase its width back to 34k {for example}, then scrolling will get crazy again ;-)

Solution?
There isn’t an easy one, 
but you can try different workarounds after pinpointing the source of problem.



Best,
