Re: [NTG-context] about \startMPanimation

[Jeong Dal]

Dear Hans,

Thank you for the clear explanation.
I thought “” is appeared because of the font problem in my system.

I did something wrong when I run the sample code, which didn’t work.

Yes, it is working well in my code now.
It makes the procedure of creating animation simpler.

Thank you and thanks Wolfgang!

Best regards,

Dalyoung

In the code, there are many “”.(\MPanimationvariables#1, 
{\??mpgraphic animation:#1})

I wonder it is correct or not.

Would you please check it?

these ??  etc indicate (protected) namespaces so it's correct

Dear Wolfgang,
