PDF::FromHTML(3pm)

Usage

    my $pdf = PDF::FromHTML->new( encoding => 'utf-8' );
    # Loading from a file:
    $pdf->load_file('source.html');
    # Or from a scalar reference:
    # $pdf->load_file(\$input);
    # Perform the actual conversion:
    $pdf->convert(
        # With PDF::API2, font names such as 'traditional' also works
        Font        => 'font.ttf',
        LineHeight  => 10,
        Landscape   => 1,
    );
    # Write to a file:
    $pdf->write_file('target.pdf');
    # Or to a scalar reference:
    # $pdf->write_file(\$output);

Overview

This module transforms HTML into PDF, using an assortment of XML transformations implemented in PDF::FromHTML::Twig.

There is also a command-line utility, html2pdf.pl, that comes with this distribution.

Hints & tips

<img> tags

Add the height and width attributes if you are creating the source HTML, it keeps PDF::FromHTML from having to open and read the source image file to get the real size. Less file I/O means faster processing.

Caveats

Although PDF::FromHTML will work with both HTML and XHTML formats, it is not designed to utilise CSS.

This means any HTML using external or inline CSS for design and layout, including but not limited to: images, backgrounds, colours, fonts etc... will not be converted into the PDF.

To get an idea of the likely resulting PDF, you may wish to use an non-CSS capable browser for testing first.

There is currently no plan to adapt this module to utilise CSS. (Patches welcome, though!)
