really Ruben I think you should stop this. My objection to the OP's
concern was that it is a distraction from what is clearly intended to
be a technical support list. I have the same objection to your threat
characterizations. There are good places to discuss your concerns but
it isn't here.

Me too. Am I the only one to have read John Callahan's book? I have no
interest in turning a technical support list into a virtue signalling
fest. Do it yourself.

gimp isn't a source and you aren't quoting. Maybe give the version
number? I don't really think it's an issue.

something I don't understand from this is your intended use; as you
point out GIMP has its area of focus, is that a good fit?

this is what I don't see a setting for. I'm using 2.8 and don't
understand where to change opacity. Sorry to be dense; the second layer
makes good sense, thanks!

[Gimp-user] translucent background?

[Dave Stevens]

I want a rectangular text box with a translucent white background. I can
make it transparent but don't see a way to get, say, 30% transparency.
Can someone refer me? will RTFM.

TIA.

[Gimp-user] overlay image in Gimp 2.8.16 ?

[Dave Stevens]

I routinely use the gimp for simple things and now want to use it to add
an image (image 2) to a background. I have modified the new image so
that its background is transparent. I have saved it as both a jpg
and .xcf. I have an existing .jpg image that I want to use as the base
layer with image2 on top. I see conceptually how to do this but am
basically lost in the layers dialogs. 

I want to add image2 to the existing image then export the merged image
as a jpg. The online tutorials I've been able to find are either
outdated or apply to some other platform/version.

I'm using Linux Mint 18.3. Will rtfm if pointed to one or a tutorial
would be useful too.

TIA
