Editing Ray opaque background

== Overview ==
This setting changes how PyMol treats the background.  If this option is ON then the background is whatever you specify -- like black or white; however, if the setting is OFF, then the background will be treated as a transparent alpha channel.

== Settings ==
Note: turning this setting '''off''' creates the transparent backgrounds.

<source lang="python">
# turn on transparent alpha channel
set ray_opaque_background, off
</source>

== Examples ==
<gallery>
Image:Rob0.png|ray_opaque_background set to 0.  The image from PyMOL is shown over a checkerboard.
Image:Rob1.png|ray_opaque_background set to 1.  The image from PyMOL is shown over a checkerboard, however because the background is opaque, the checkerboard underneath does not show through.
