When you use "import" for a screenshot, it requires a filename to write to. This can be a hassle sometimes. Here is a trick I came across to capture the screenshot to memory. I still need to use backticks to run import, and if anyone knows how to do this from PerlMagick, your input would be appreciated. 
#!/usr/bin/perl
use warnings;
use strict;
use Image::Magick;

my $blob = `import jpg:-`;
#my $blob = `import -`;  #postscript produced 
#print "$blob\n"; 
                              
# now $blob is in memory and you can do what you 
# want with it. 
                              
my $output = Image::Magick->new(magick=>'jpg');
$output->BlobToImage( $blob );
#$output->Resize(geometry=>'160x120'); 
$output->Write(time.'.jpg');
