I seem to be having a problem with Image::Magick in Mason. The following code works great at a CGI script:

#!/usr/bin/perl

use strict;
use Image::Magick;

$| = 1;

my $image = Image::Magick->new;
$image->Set (size => '500x750');
$image->Read ('xc:black');

print "Content-Type: image/png\n\n";
binmode STDOUT;
$image->Write ('png:-');
exit 0;

Notice that I'm turning off buffering ($| = 1) and using the Write() routine to go to STDOUT.

Now, when I do this in Mason:

<%perl>
use Image::Magick;

$| = 1;

my $image = Image::Magick->new;
$image->Set (size => '500 x 750');
$image->Read ('xc:black');

$m->clear_buffer;
$r->content_type ('image/png');
$image->Write ('png:-');
$m->abort;
</%perl>

[download]

I get nothing sent to the browser but the header. I'm assuming that the Write() that Image::Magick is using is somehow bypassing the Mason mechanisms here. I've tried sprinkling $m->flush_buffer around too, but to no effect.

How is Mason handling STDOUT and how is Image::Magick? I'd like to see if I could get Mason working with it. Otherwise, I should be able to create a temporary .PNG and then feed it out to STDOUT manually (although I've yet to be successful creating a .PNG from Mason using Image::Magick either). But I assume that's some sort of file security problem.

THANKS for any and all hints and tips that you can provide. I know we're all very busy so it's TRULY appreciated!
