What does the pass through option mean in the cut settings on light burn?

Question

In the cut settings editor there is a toggle button labeled pass through.  What is it for?

Answer 1

Light burn normally processes images that you import for engraving to match the dpi and size you tell it and to dither it.  If you dither or otherwise process the image outside of light burn you don't want light burn changing anything. Pass through tells it to just use the image as is.
