Slice background

I create and save a Slice in Engrave Mode. When I retrieve it to put into a Graphics frame, the background is either transparent (the paper color) or white, I can’t predict which. How can I know and control which it will be?

Are you setting the slice as Color or Mono. IIRC, setting the slice to color allows for a transparent background in some formats (like PNG).

That’s exactly what I need. Thank you!
