+SL::Helper::CreatePDF - A helper for creating PDFs from template files
+
+=head1 SYNOPSIS

+  # it:
+  my $order               = SL::DB::Order->new(id => …)->load;

+  $print_form->{format}   = 'pdf',
+  $print_form->{media}    = 'file';
+
+  $order->flatten_to_form($print_form, format_amounts => 1);
+  $print_form->prepare_for_printing;

+  my $pdf = SL::Helper::CreatePDF->create_pdf(

+  );
+
+=head1 FUNCTIONS
+
+=over 4
+
+=item C<create_pdf %params>
+
+Parses a LaTeX template file, creates a PDF for it and returns either
+its content or its file name. The recognized parameters are the same
+as the ones for L</create_parsed_file> with C<format> and
+C<template_type> being pre-set.
+
+=item C<create_parsed_file %params>
+
+Parses a template file and returns either its content or its file
+name. The recognized parameters are:
+
+=over 2
+
+=item * C<template> – mandatory. The template file name relative to
+the users' templates directory. Must be an existing file name,
+e.g. one retrieved by L</find_template>.
+
+=item * C<variables> – optional hash reference containing variables
+available to the template.
+
+=item * C<return> – optional scalar containing either C<content> (the
+default) or C<file_name>. If it is set to C<file_name> then the file
+name of the temporary file containing the PDF is returned, and the
+caller is responsible for deleting it. Otherwise a scalar containing
+the PDF itself is returned and all temporary files have already been
+deleted by L</create_pdf>.
+
+=item * C<format> – optional, defaults to C<pdf> and determines the
+output format. Can be set to C<html> for HTML output if
+C<template_type> is set to C<HTML> as well.
+
+=item * C<template_type> – optional, defaults to C<LaTeX> and
+determines the template's format. Can be set to C<HTML> for HTML
+output if C<format> is set to C<html> as well.
+
+=back
+
+=item C<find_template %params>
+
+Searches the user's templates directory for a template file name to
+use. The file names considered depend on the parameters; they can
+contain a template base name and suffixes for email, language and
+printers. As a fallback the name C<default.$extension> is also
+considered.
+
+The return value depends on the context. In scalar context the
+template file name that matches the given parameters is returned. It's
+a file name relative to the user's templates directory. If no template
+file is found then C<undef> is returned.
+
+In list context the first element is the same value as in scalar
+context. Additionally a list of considered template file names is
+returned.
+
+The recognized parameters are:
+
+=over 2
+
+=item * C<name> – mandatory. The template's file name basis
+without any additional suffix or extension, e.g. C<sales_quotation>.
+
+=item * C<extension> – optional file name extension to use without the
+dot. Defaults to C<tex>.
+
+=item * C<email> – optional flag indicating whether or not the
+template is to be sent via email. If set to true then template file
+names containing C<_email> are considered as well.
+
+=item * C<language> and C<language_id> – optional parameters
+indicating the language to be used. C<language> can be either a string
+containing the language code to use or an instance of
+C<SL::DB::Language>. C<language_id> can contain the ID of the
+C<SL::DB:Language> instance to load and use. If given template file
+names containing C<_language_template_code> are considered as well.
+
+=item * C<printer> and C<printer_id> – optional parameters indicating
+the printer to be used. C<printer> can be either a string containing
+the printer code to use or an instance of
+C<SL::DB::Printer>. C<printer_id> can contain the ID of the
+C<SL::DB:Printer> instance to load and use. If given template file
+names containing C<_printer_template_code> are considered as well.
+
+=back
+
+=item C<merge_pdfs %params>
+
+Merges two or more PDFs into a single PDF by using the external
+application ghostscript.
+
+The recognized parameters are:
+
+=over 2
+
+=item * C<file_names> – mandatory array reference containing the file
+names to merge.
+
+=back
+
+Note that this function relies on the presence of the external
+application ghostscript. The executable to use is configured via
+kivitendo's configuration file setting C<application.ghostscript>.
