Preserving sets and their free transform #17
Description
Hello,
I've noticed that there is no easy way to preserve a set and its free transform if it has one. I'm wondering if you've given this any thought? I've managed to accomplish this but it is fairly awkward looking code in my opinion.
Regards,
Dan H.

What do you mean by "preserve a set", are you exporting/importing using Raphael.JSON?

Yes, using Raphael.JSON. I see in the readme it talks about preserving sets and then also a section about using it in conjunction with Raphael.FreeTransform. However, if i create a set and then FreeTransform that set. I don't see a way to preserve the set and the set's FreeTransform attributes. Only for individual items. So when i try to use FreeTransform on the set again, it is starting from a blank slate instead of from where i may have left it before serializing/deserializing. Hopefully this makes sense.

You need to save the value of
ft.attrswhen serialising and re-apply those attributes after de-serialising. You can useft.offsetto set the initial rotation/scale/translation of the set which will fix the issue you're having. E.g.ft.offset.rotate = 45will place the handles at a 45 degree angle without rotating the set.danhamlin commentedon Jan 23, 2013
Ah, thank you for the info. I'll give it a try.
