Hi
i am a new user of pdl ,i have tried to run the color code listed in
http://search.cpan.org/~chm/PDL-2.4.7/Graphics/Graphics2D.pm
and i have posted recently a message to perlmonk, finally i have found that i
need the file imag2d.pdl, i can't find the file in my perl folder nor in the
PDL-2.4.7.tar.gz source , but i found it in the PDL-2.4.6.tar.gz source, i have
downloaded a newer file from
http://sourceforge.net/tracker/?func=detail&atid=300612&aid=2925007&group_id=612
is it planned to include the file in a future package ?.
this is my last successfull code to display the color code found in
Graphics2D.pm
its image like a redish dusk sky over a green ground (an art painting)

this is working well on ms windows if putting the file imag2d.pdl in the same
folder of the code
use PDL;
use PGPLOT;
use PDL::Graphics2D; #imports imag2d() and twiddle()
use PDL::AutoLoader;
our @PDLLIB;
push @PDLLIB, '.';
#my $winopt = {Device => '/GW', WindowWidth => 7, Aspect => 1};
#my $w = PDL::Graphics2D->new('PGPLOT');
$a = sequence(64,48,3); # make test RGB image
$a = $a->mv(2,0); # color must be dim(0) with size [0..4]
$a /= $a->max; # pixel values in [0.0,1.0]
$a = sin(10*$a);
imag2d($a);
on ms windows this code working well, on linux mint i get error :
Your vendor has not defined OpenGL macro GLUT_ACTION_ON_WINDOW_CLOSE, used at
(eval 36) line 415. what is this meaning . on linux i have'nt plplot installed
yet.
also in the synopsis of the PDL::Graphics2D there is:
$win = PDL::Graphics2D->new(<Interface>, <Options>);
i have commented it above because if i uncomment it i will get two windows the
first for the plot and the second an empty window covering with persistence the
plot window, so how to use exactly
$win = PDL::Graphics2D->new(<Interface>, <Options>);
to display the plot to the screen,
at last thanks very much for the wonderfull PDL module, especially the 3D
features with PDL::Graphics::TriD
best wishes
