So I'm building a perl/dancer app and I want to serve an image at a url like this:
mysite.com/image.png (which will be generated at runtime)
I did this:
get '/image' => sub {
# create a new image
my $im = new GD::Image(100,100);
# allocate some colors
my $white = $im->colorAllocate(255,255,255);
my $black = $im->colorAllocate(0,0,0);
my $red = $im->colorAllocate(255,0,0);
my $blue = $im->colorAllocate(0,0,255);
# make the background transparent and interlaced
$im->transparent($white);
$im->interlaced('true');
# Put a black frame around the picture
$im->rectangle(0,0,99,99,$black);
# Draw a blue oval
$im->arc(50,50,95,75,0,360,$blue);
# And fill it with red
$im->fill(50,50,$red);
content_type 'image/png';
binmode STDOUT;#don't think this makes a diff.
send_file($im->png);
};
But, I end up getting a broken image and 400 BAD request in the network log. Any ideas?
I tried putting it all in a eval, no errors there.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>

Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
