Dear All,

I am faced with a Problem related perl GD. I am generating random colors and using it to draws lines and polygons in a loop. What I observed was after certain number of cycles, the line color allocated is not changing. I tried to print the output of RGB which appears to be all different. I was wondering whether there is any limit in size in using the colorAllocate method (if so how can I handle the issue)or is there any thing wrong in the way I am implicating it. The following code would reproduce the problem. Thanks for your attention. Please note that I am new to GD. Nagesh 

#!/usr/local/bin/perl
use GD;
$im = new GD::Image(1000,20);
$ctr =0;
$x=0;
$y=10;
while ($ctr <1000)
{    
    $randomRed=int(rand(256))+0;
    $randomGreen=int(rand(256))+0;
    $randomBlue=int(rand(256))+0;
    $getColor=$im->colorAllocate($randomRed,$randomGreen,$randomBlue);
    $im->line($x,$y+5,$x,$y-5,$getColor);
    $x++;
    $ctr++
}
print $im->png;
