The documentation is found here
Heh. That's sort of a sketch of the docs. That's not the real docs. The real docs do not exist. Most of the time, I end up starting from one of the tests in the Perl module distro, and then slowly mutating it to make sure it still works and is still doing what I want it to do.
On a recent 15-line script (to grab the the timestamps from the EXIF data), I ended up having to stare at the C sources for about an hour, and just "try" things repeatedly. I'm no dummy, and it took me that long. Gah.
I'm not sure what it is about image-manipulation software that makes them all: (a) fragile, (b) underdocumented, and (c) hard to install. It's very consistent.

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).

or How to display code and escape characters
are good places to start.
