Is there a way to script the generation of images?

[hartzell]

Is there a way to script the generation of image files like the example-usage.png image?

I'd like to generate a series of static (yawn) images so that I could stuff them into non-browser presentation software.

I've seen comments in the issues about doing screengrabs.

I also found a suggestion in an issue comment to use a "jsfiddle", e.g. http://jsfiddle.net/fracz/q76vj8ow/, from which I could save the image.

I'd like to have a series of files that I could version control and an automate-able way to generate a stack of images from them.

Is there a reasonable way to do this?

Thanks!
