I don't pretend to know what is going on, but as I was bored, here are a couple of things that I did to your code, and I did end up with a functioning PDF:
- use non-interlaced PNG with $image->interlaced(undef); in the PNG sub
- throw in a $hPdf->save; at the end of the PDF sub
- make sure your media box is large enough (at least 800x600 in your case)
Hope this helps!
Update: Versions I used (:
- Perl 5.8.3 as ActiveState build 809 on Win2k
- GD::Graph::bars 1.25
- PDF::API2 0.3r77
It also appears that the stringify is messing things up - either put the save before it or just remove it altogether as it serves no useful purpose (at least in this code fragment).

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>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
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).
