In PGPLOT, color index 0 is background and 1 is foreground. To change
the two you'd use the PGPLOT function pgscr():
use PGPLOT;
use PDL::Graphics::PGPLOT
dev 'file.png/png';
pgscr(0, 1, 1, 1); # set bg to white
pgscr(1, 0, 0, 0); # set fg to black

I am new to PDL & PGPLOT. Yesterday I just installed this for Windows.
I have figured out how to create and plot my own data into a
dev=("/PNG") *.png file.
However, when this file gets created the background is Black and the
type and plot axis is White.
This consumes a great amount of ink when printed on my printer.
Ive executed: pdldoc PDL::Graphics::PGPLOT::Window
To read the online help about PGPLOT's Window options, but I cant seem
to find the information I need here...
If someone can please provide a brief code fragment, t his would be very
helpful to me.
Thanks in advance...
