Using a Background Image in VFB+

Recently, I received the following request from a user:

I noticed you have the option of a custom background color. Is it possible to have a custom background image?

To which I instinctively replied:

That sounds like a great idea, I’ll add it to my to-do list.

Only when starting to implement this feature, did I realize that it already existed. All you have to do in order to use a custom background image in VFB+ is:

  1. Load your custom background as a regular image.
  2. Set A/B mode to composite A over B
  3. Use your foreground as A and background as B.
