Hi,
I am finding a bit peculiar that graphics command are bounded to
technologies.
PlPlot has the xyplot while PGPLOT has commands like imag.
The result is that what is suitable to be shown on one is not for
the other as the vectorization acts differently. I think that
missing the ability to show color backgrounds can be a little
outdated.
I am probably missing something.
How could I load a color background on plplot and then write on it?
I am grateful to all developing PDL. I only think that B/W today is
about using the Nokia 6110.

Fabio,
I have heard about a version of PGPLOT that implements rgbi(),
but, as Matt also mentioned, I have never found it either. For
programmatically manipulating images, I found ImageMagick (http://www.imagemagick.org/script/index.php)
and its Perl bindings PerlMagick to be both powerful and
exceptionally simple to use. Due to PDL's reliance upon PGPLOT as
its primary graphics library, I only use it to manipulate
greyscale images. However, I do believe that is all about to
change in PDL 4.10 with the addition of PLPLOT and Prima. However,
I shall let others who are much more familiar with those
extensions describe their utility.
Thanks.

Hi Fabio,
I encountered this problem before, and there's some version
of PGPLOT floating out there that does implement it, but I never
seem to find it again... I *think* Karl Glazebrook got one
version of it working some time ago, but my memory's rusty on
the matter.

Hi,
I get this message trying to display a jpg image.
I found several results on Google about this but I wound
understand the current state of the thing.
I got this using rim. Is there a solution
or a workaround?
