Yes, I request a transparent background for PNG images saved by movie recording.
Like what the `save <filename> format PNG transparentBackground true` command does.
I figure it’s not too much of a stretch for you because `save` and PNG supports this.
 
I am using the PNG images for a web page (see: https://www.thirdlawtx.com)
That is preliminary and I will add attribution.
I want to use `rock` and save a movie made up of a bunch of PNG files and then use the scrolling animation that you see on that web page.   Transparent backgrounds will make it easier to change the background color of the website without having to go back to chimera/X and re-render everything each time we change the background.
 
Chimera/X works great!  Thanks!"	defect	closed	moderate		Input/Output		fixed		Elaine Meng				all	ChimeraX
