Re: Background color



Here's one way, and it allows you to use other colors as well
besides black with a white pen. It'll work in any of Ferret's
plotting modes.

You can set a viewport covering the entire window and fill that with
black (or any other color) and then make your plot in an identically-
sized viewport which will appear on top of the first one. Setting the
foreground pen to white does work in gif mode.

! Define a viewport with the /AXES qualifier so there are no margins

DEFINE VIEWPORT/X=0:1/Y=0:1/AXES full2
SET VIEW full2
SHADE/I=1:2/J=1:2/PALETTE=black i+j

! Now set to the pre-defined viewport FULL
! Set the main pen color to white (as in the script black.jnl)

SET VIEW full
PPL COLOR 1 100 100 100
GO ptest ! a test plot

This gives us a lot more flexibility with colors. Try this:

DEFINE VIEWPORT/X=0:1/Y=0:1/AXES full2
SET VIEW full2
SHADE/I=1:2/J=1:2/PALETTE=yellow i+j

SET VIEW full
PPL COLOR 1 100 0 0
GO ptest

Dear ferreters:


How can I keep the background color?

To make a better slideshow, I tried to change
background color by using "go black".

It works in displaying a picture in computer monitor.

But the background is still white when it is
transferred into a postscript file.

Fprint -l cps -o file.ps -R metafile.plt
