[chimerax-users] Reproduce exact view

[Alexis Rohou]

Hi Christophe,

I prepare my figures using ChimeraX command (.cxc) scripts and I believe I
have a workflow that lets me reproduce exact views. I know it's not 100%
robust, but it's reliable enough for me. It basically relies on a sequence
of close; windowsize; view matrix; zoom; clip; save.

Here is a pseudo script. To work out the values you need for the matrices,
just move your point of view and your models until you are happy, then do
"view matrix".  I have not worked out a good way to get the distances for
the clip planes. So I just play with them on the command line until I get
the look I want, then save the values in my cxc file.

Hope this helps & that more experienced users can chime in with
improvements.

Cheers,
Alexis
