When we collapse a group getting error

If you could provide a minimal complete sample that demostrates the problem, that would be most helpful.

Can you please create a group with a node . Node image is in svg format with height * width is 2 * 14.
Can you please check if group collapse issue is there or not?

Could you please post the content of the SVG file you are using?

Please read GoJS Pictures -- Northwoods Software

Here is a sample SVG file in Base64 format

Ah, thank you – we now have enough to be able to reproduce the problem. We’ll investigate this today.

Thanks for reporting this. This has been fixed and will be out with the next release, probably within a week.

We have just released 2.0.15, which fixes this bug.

Thanks again for reporting.

Thanks a lot.
