Hi Andrew,
thanks for your help. Actually, I did not want to trigger a download,
but rather just serve an image generated dynamically.
One way to solve the original problem that worked for me was writing
down a file to a public location and redirecting the client to that
location.
You however answered my question: printing through $m->print as you
suggested did the trick. I was attempting:
my $bin = File::Slurp::read_file( $file, binmode => ':raw' ) ;
$m->res->body( $bin );
but this resulted in a corrupted image on the client side. (Why?)
Thank you very much,
=BO
PS: Why is it that there is no need for
CLASS->no_wrap;
in the file?
PPS: In HTML::Mason, $r->sendfile was available;
Is there any direct equivalent?
