I've been looking through SWISH::Filters::Pdf2HTML, and I just realize
more and more all the time that I'm no Perl expert.

I don't see any code that looks like what you have there.  I see code in
sub filter() that sets a title.  Do I monkey around in there?  That
looks, to me, like a good way to break something.


Now, as an alternative, I find that I can actually set a title in my PDF
file, using pdftk.  It's kind of convoluted, but it works okay.

I see that Pdf2HTML mentions that it can store the title, but it doesn't
work by default.  (By which I mean that I have manually set some titles
in my PDF files, run the index, perform a search, and it shows the file
name as the hyperlink, rather than the PDF file's internal title)

---------------------------------
You may pass into SWISH::Filter's new method a tag to use as the html
<title> if found in the PDF info tags:

    my %user_data;
    $user_data{pdf}{title_tag} = 'title';

    $was_filtered = $filter->filter(
        document  => $filename,
        user_data => \%user_data,
    );

Then if a PDF info tag of "title" is found that will be used as the HTML
<title>.
---------------------------------

Does this mean that if I copy the actual code (skipping comments, of
course), from the above quoted section, and place it into the sub new()
function, that I will be adding in the ability to read the titles?  If
so, where do I put it?  Before the return statement obviously (even to
me), but does it go inside of bless(), before it, after it?


Am I even close here?
