Here is a tk script which will continually grab an image from a webcam URL, you could modify it to save the current image with a button press.
#!/usr/bin/perl -w
use strict;
use Tk;
use LWP::UserAgent;
use Tk::JPEG;
use MIME::Base64;
my $ua = LWP::UserAgent->new(
timeout => 30,
keep_alive => 1
);
sub get_photo {
my $r = $ua->get('http://localhost/~zentara/images/webcam.jpg');
return $r->content if $r->is_success;
}
my $mw = new MainWindow;
my $l = $mw->Label(
-text => 'Zcam',
-foreground => 'blue',
-font => [qw/-size 100 -slant italic/]
);
$l->pack();
my $time = localtime;
my $datelabel = $mw->Label(-text => $time )->pack(-expand => 1, -fill
+=> 'both');
$mw->Button(-text => 'Quit', -command => [destroy => $mw])->pack;
$mw->repeat(
#10000 = 10 second update
10000 => sub {
$l->configure(
-image => $mw->Photo(
-data => encode_base64( get_photo() ),
-format => "jpeg"
)
);
my $time = localtime;
$datelabel->configure(
-text => $time
);
}
);
MainLoop;
