You can snapshot any object singly even if other controls overlap or lay under it. Another advantge is that the object does not need to be visible when getting a snapshot. It can even be on a different card.

Richmond's right about groups, I forgot about that. The object export is handy there too if there are images or controls in the group you don't want to capture; you can single out one control inside the group and snapshot that without worrying about the other controls underneath or a background color set on the group.

If I were playing with this image and wanted to save the result without the button I can export only the image object. I did this from another card in the stack. The yellow border is an effect applied to the group.

I don't see it working here. Either that, or your interpretation of what should be in the final export isn't what I'm interpreting should be there.

Relevant config:
LC 9.6.2 RC2
Ubuntu 20.04.2 LTS (stock, w/ Gnome Shell)

Relevant button properties:
ink: blendDst
dropShadow["opacity"]: 101
innerGlow["opacity"]: 178

Using this: ...on this: ...gives me this: Import that attached exported image into LC or a graphics program to see the PNG alpha channel working, e.g.:

I see. Thank you all for the explanation, apparently my interpretation is off, oh well.
