error in animation

error in animation

[Jeong Dal]

After updating ConTeXt standalone, \startanimation … \stopanimation is not working.
Here is a sample code and its log file. I tried another animation and have the same error message at \stopanimation line.

What is wrong in this code?

Thank you.

Best regards,

Dalyoung

It’s a bug with the \fontchar command which is used for the navigation symbols. A minimal example is shown below.

\starttext
\fontchar{A}
\stoptext

Hi Jeong,

in your code you need to add braces after each external figure command:

{\externalfigure[dummy][]}{}

Works fine with ConTeXt  ver: 2014.09.26 11:42 MKIV beta

Dear Wolfgang,

I am using animation feature frequently for the class materials.
It is very convenient to use \startanimation … \stopaimation.
It reduces many steps which I have to define.
Thank you for a nice module.

I’d like to ask you to add caption feature like \startcombination.

When I show the figures one by one, it is better to put a caption sometimes.
If you think that it is not too bad, would you please concern to add the feature?

I am sorry to ask too much.

Thank you again.

Best regards,

Dalyoung

I added {} at the end, but I still got the same error.

The previous bata version may be OK, but the latest version has a problem as Akira said.

Thank you for testing.
