RSI's David Stern pointed out to me and others than IDL has a built
in function (COLOR_QUAN) that allows the display of 24 bit color on
8 bit color displays.

One minor warning: it was a recent addition to IDL.

That means that PV-Wave does not possess it. At least not in the
versions we use--perhaps it has been added?

I try to keep my code portable between IDL and PV-Wave
because I primarally use IDL/PV-Wave as a semi-portable graphics and
image interface among PC's and a variety of Unix boxes, which have
various IDL or PV-Wave versions installed.

Of course, I could always install the free trial version of IDL, but
its limitations (no file output, except stuff like postscript, no
SPAWNs, 7 minute limit) are a nuisance.

For those without that problem, this, along with support for more image
file formats, and the fancy widget stuff, is one of a number of clear
advantages of IDL over PV-Wave for those interested in image work. I
can't figure out why PV-Wave is more expensive. Especially since, if
you exceed the license, IDL reverts to free trial mode, whereas
PV-Wave won't let you in at all. Any thoughts on this?
