Dear monks,
How do you think I can optimize this code:
my @allpixels = split( /,/ , $pixellist );
my @rgbvals;

foreach my $pixel (@allpixels) {
  push @rgbvals, ($pixel >> 16 & 255, $pixel >> 8 & 255, $pixel & 255)
+;
}

my $newblob = pack "C*", @rgbvals;

In this example my first list is:
(9347248,9347248,9413041)
and second list is:
(142,160,176,142,160,176,143,161,177) which represents:
(R,G,B,R,G,B,R,G,B)
I was thinking of using unpack() instead of  $pixel >> 16 & 255, $pixel >> 8 & 255, $pixel & 255
Do you think that unpack will perform better?
