In PyFerret
SET WINDOW /COLOR=BLACK 1
gives a transparent background whereas
SET WINDOW /COLOR=(0,0,0,100)
gives an opaque black background. I assume there is something in the Ferret code to intentionally cause this to happen.
Also,
PLOT /VS /LINE /COLOR=white /THICK=15
gives a thick magenta (purple) line (color 6). But if first
SET MODE LINE 7
then the line is white. (White is now the seventh standard color, but is not part of the standard line bundles by default so it will not be auto-selected.) Again, I assume there is something in the Ferret code to intentionally cause this to happen since thin white used to be pen/color 19.
