+SL::ReportGenerator.pm: the kivitendo way of getting data in shape
=head1 SYNOPSIS
$report->add_data($row1, $row2, @more_rows);
$report->generate_with_headers();
-This creates a report object, sets a few columns, adds some data and generates a standard report.
+This creates a report object, sets a few columns, adds some data and generates a standard report.
Sorting of columns will be alphabetic, and options will be set to their defaults.
The report will be printed including table headers, html headers and http headers.
Then it lacks usability. You want it to be able to sort the data. You add code for that.
Then there are too many results, you need pagination, you want to print or export that data..... and so on.
-The ReportGenerator class was designed because this exact scenario happened about half a dozen times in Lx-Office.
-It's purpose is to manage all those formating, culling, sorting, and templating.
-Which makes it almost as complicated to use as doing the work for yourself.

=head1 FUNCTIONS
=item set_sort_indicator $column,$direction
-Sets sorting ot the table by specifying a column and a direction, where the direction will be evaluated to ascending if true.
-Note that this is only for displaying. The data has to be presented already sorted.
+Sets sorting of the table by specifying a column and a direction, where the direction will be evaluated to ascending if true.
+Note that this is only for displaying. The data has to have already been sorted when it was added.
=item add_data \@data
=item add_data \%data
-Adds data to the report. A given hash_ref is interpreted as a single line of data, every array_ref as a collection of lines.
-Every line will be expected to be in a kay => value format. Note that the rows have to be already sorted.
-ReportGenerator does only colum sorting on its own, and provides links to sorting and visual cue as to which column was sorted by.

+
+The ReportGenerator is only able to display pre-sorted data and to indicate by
+which column and in which direction the data has been sorted via visual clues
+in the column headers. It also provides links to invert the sort direction.
=item add_separator
=item add_control \%data
Adds a control element to the data. Control elements are an experimental feature to add functionality to a report the regular data cannot.
-Every control element needs to set IS_CONTROL_DATA, in order to be recongnized by the template.
+Every control element needs to set IS_CONTROL_DATA, in order to be recognized by the template.
Currently the only control element is a colspan element, which can be used as a mini header further down the report.

=item prepare_html_content $column,$name,@column_headers
-Parses the data, and sets internal data needed for certain output format. Must be called once before the template is invoked.

+Parses the data, and sets internal data needed for certain output format. Must be called once before the template is invoked.

+
=item generate_html_content
The html generation function. Is invoked by generate_with_headers.
=item generate_pdf_content
-The PDF generation function. It is invoked by generate_with_headers, tests whether or not the Perl module PDF::API2 is installed and calls render_pdf_with_pdf_api2 if it is and render_pdf_with_html2ps otherwise.
-
-=item generate_csv_content
+The PDF generation function. It is invoked by generate_with_headers and renders the PDF with the PDF::API2 library.
-The CSV generation function. Uses XS_CSV to parse the information into csv.
+If the param want_binary_pdf is set, the binary pdf stream will be returned.
+If $pdfopts->{print} && $pdfopts->{printer_id} are set, the pdf will be printed (output is directed to print command).
-=item render_pdf_with_pdf_api2
+Otherwise and the default a html form with a downloadable file is returned.
-PDF render function using the Perl module PDF::API2.
-
-=item render_pdf_with_html2ps
+=item generate_csv_content
-PDF render function using the external application html2ps.
+The CSV generation function. Uses XS_CSV to parse the information into csv.
=back
=item allow_pdf_export
-Used to determine if a button for PDF export should be displayed. Default is yes. The PDF button is hidden if neither the Perl module PDF::API2 nor the external applications html2ps and Ghostscript are available regardless of this parameter's value.
+Used to determine if a button for PDF export should be displayed. Default is yes.
=item allow_csv_export
The template to be used for HTML reports. Default is 'report_generator/html_report'.
+=item controller_class
+
+If this is used from a C<SL::Controller::Base> based controller class, pass the
+class name here and make sure C<SL::Controller::Helper::ReportGenerator> is
+used in the controller. That way the exports stay functional.
+
=back
=head2 PDF Options
Landscape or portrait. Default is landscape.
-=item font_name
+=item font_name
Default is Verdana. Supported font names are Courier, Georgia, Helvetica, Times and Verdana. This option only affects the rendering with PDF::API2.
Include headers? Default is yes.
+=item encoding
+
+Character encoding. Default is UTF-8.
