DESCRIPTION

Catalyst::View::Wkhtmltopdf is a Catalyst View handler that converts HTML data to PDF using wkhtmltopdf (which must be installed on your system). It can also handle direct conversion of TT templates (via the Catalyst::View::TT manpage).


CONFIG VARIABLES

stash_key

The stash key which contains data and optional runtime configuration to pass to the view. Default is wkhtmltopdf.

tmpdir

Name of URI parameter to specify JSON callback function name. Defaults to callback. Only effective when allow_callback is turned on.

command

The full path and filename to the wkhtmltopdf command. Defaults to /usr/bin/wkhtmltopdf.

allows

An arrayref of allowed paths where wkhtmltopdf can find images and other linked content. The temporary directory is added by default. See wkhtmltopdf documentation for more information.

disposition

The content-disposition to set when sending the PDF file to the client. Can be either inline or (default) attachment.

filename

The filename to send to the client. Default is output.pdf.

page_size

Page size option (default: a4). See wkhtmltopdf documentation for more information.


PARAMETERS

Parameters are passed fvia the stash:

    $c->stash->{wkhtmltopdf} = {
        html    => $web_page,
    };

You can pass the following configuration options here, which will override the global configuration: disposition, filename, page_size.

Other options currently supported are:

page-width, page-height

Width and height of the page, overrides page_size.

margin-top, margin-right, margin-bottom, margin-left

Margins, specified as 3mm, 0.7in, ...

Have a look at wkhtmltopdf documentation for more information regarding these options.


CHARACTER ENCODING

At present time this library just uses UTF-8, which means it should work in most circumstances. Patches are welcome for support of different character sets.


REQUIREMENTS

wkhtmltopdf command should be available on your system.


TODO

More configuration options (all the ones which wkhtmltopdf supports, likely) should be added. Also, we'll wanto to allow to override them all at runtime.

We might want to use pipes (the IPC::Open2 manpage) instead of relying on temp files.

And yes... we need to write tests!
