Dont know how to do this in CCP4MG or POVRAY but you can do it in GIMP
with the following

Layer>Transparency>Add Alpha Chanel
Select>By color (Select the background with your mouse)
Edit>Cut (to remove the background)

Subject: [ccp4bb] ccp4mg povray rendering

Hi all,

I am generating images using ccp4mg (which is wonderful by the way), but I
can not figure out how to generate a povray input file that will yield an
image with a transparent background. Getting a transparent background using
the screen snapshot works fine, but I would like to have a rendered image.
I have tried adding the +UA tag (which I believe should render the alpha
channel as transparent) as a povray command line option so that my input
looks like such:

povray +A +J0 +Q9 +UA +H2400 +W2400 input_file.pov

Yet this still does not give me a transparent background. When generating
povray input files, does ccp4mg output the background as the alpha channel
or do I need to go about this a different way?

Thanks,

Ray
