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. - Tim ---------- Forwarded message ---------- From: Matthew Kenworthy <[email protected]> To: [email protected] Cc: "[email protected]" <[email protected]> Date: Sun, 22 Jan 2012 21:07:06 +0100 Subject: Re: [Perldl] PGPLOT rgbi called, but RGB support is not present. Using grayscale instead. 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.

Using grayscale instead. 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?
