|

=head1 DESCRIPTION
|
||||
| a5a81f46 | Moritz Bunkus | This class is a utility for use with the PDF::API2 module from CPAN.
|
||
It can be used to display text data in a table layout within a PDF.
|
||||
The text data must be in a 2D array (such as returned by a DBI statement handle fetchall_arrayref() call).
|
||||
The PDF::Table will automatically add as many new pages as necessary to display all of the data.
|
||||
Various layout properties, such as font, font size, and cell padding and background color can be specified for each column and/or for even/odd rows.
|
||||
Also a (non)repeated header row with different layout properties can be specified.
|
||||
| 42b702a6 | Moritz Bunkus | |||
| ca2ec834 | Sven Schöling | See the L</METHODS> section for complete documentation of every parameter.

| 42b702a6 | Moritz Bunkus | =over
|
||
| ca2ec834 | Sven Schöling | =item Description
|
||
Generates a multi-row, multi-column table into an existing PDF document based on provided data set and settings.
|
||||
=item Parameters
|
||||
$pdf - a PDF::API2 instance representing the document being created
|
||||
$page - a PDF::API2::Page instance representing the current page of the document
|
||||
$data - an ARRAY reference to a 2D data structure that will be used to build the table
|
||||
| a5a81f46 | Moritz Bunkus | %settings - HASH with geometry and formatting parameters.
|
||
| ca2ec834 | Sven Schöling | |||
For full %settings description see section L</Table settings> below.
|
||||
| 42b702a6 | Moritz Bunkus | This method will add more pages to the pdf instance as required based on the formatting options and the amount of data.
|
||
| a5a81f46 | Moritz Bunkus | =item Returns
|
||
| 42b702a6 | Moritz Bunkus | |||
| a5a81f46 | Moritz Bunkus | The return value is a 3 items list where
|
||
| ca2ec834 | Sven Schöling | |||
$final_page - The first item is a PDF::API2::Page instance that the table ends on
|
||||
$number_of_pages - The second item is the count of pages that the table spans on
|
||||
$final_y - The third item is the Y coordinate of the table bottom so that additional content can be added in the same document.

|
||
| 42b702a6 | Moritz Bunkus | |||
If used the parameter 'new_page_func' must be a function reference which when executed will create a new page and will return the object back to the module.
|
||||
For example you can use it to put Page Title, Page Frame, Page Numbers and other staff that you need.
|
||||
Also if you need some different type of paper size and orientation than the default A4-Portrait for example B2-Landscape you can use this function ref to set it up for you. For more info about creating pages refer to PDF::API2 PAGE METHODS Section.
|
||||
| ca2ec834 | Sven Schöling | Don't forget that your function must return a page object created with PDF::API2 page() method.

| a5a81f46 | Moritz Bunkus | =item B<cell_render_hook> - CODE reference to a function called with the current cell coordinates. If used the parameter 'cell_render_hook' must be a function reference. It is most useful for creating a url link inside of a cell. The following example adds a link in the first column of each non-header row:
|

cell_render_hook => sub {
|

my ($page, $first_row, $row, $col, $x, $y, $w, $h) = @_;

# Do nothing except for first column (and not a header row)

return unless ($col == 0);

return if ($first_row);
|

# Create link
|

my $url = "https://${hostname}/app/${value}";

|
||
If the 'header_props' parameter is used, it should be a hashref. Passing an empty HASH will trigger a header row initialised with Default values.
|
||||
There is no 'data' variable for the content, because the module asumes that first table row will become the header row. It will copy this row and put it on every new page if 'repeat' param is set.

|
||
| a5a81f46 | Moritz Bunkus | If the 'column_props' parameter is used, it should be an arrayref of hashrefs,
|
||
with one hashref for each column of the table. The columns are counted from left to right so the hash reference at $col_props[0] will hold properties for the first column from left to right.
|
||||
| ca2ec834 | Sven Schöling | If you DO NOT want to give properties for a column but to give for another just insert and empty hash reference into the array for the column that you want to skip. This will cause the counting to proceed as expected and the properties to be applyed at the right columns.
|

Each hashref can contain any of the keys shown below:
|

| 42b702a6 | Moritz Bunkus | =over
|
||
| ca2ec834 | Sven Schöling | =item B<min_w> - Minimum width of this column. Auto calculation will try its best to honour this param but aplying it is NOT guaranteed.

B<Value:> can be any whole number satisfying 0 < min_w < w
|
||||
B<Default:> Auto calculated
|
||||
=item B<max_w> - Maximum width of this column. Auto calculation will try its best to honour this param but aplying it is NOT guaranteed.
|
||||
B<Value:> can be any whole number satisfying 0 < max_w < w
|
||||
B<Default:> Auto calculated
|
||||
=item B<font> - instance of PDF::API2::Resource::Font defining the fontf to be used in this column
|

B<Value:> can be any PDF::API2::Resource::* type of font

B<Value:> can be any positive number
|

B<Default:> 'font_size' of the table.
|

=item B<font_color> - Font color of this column

B<Value:> Color specifier as 'name' or 'HEX'
|
||||
B<Default:> 'font_color' of the table.
|
||||
| a5a81f46 | Moritz Bunkus | =item B<font_underline> - Font underline of this cell
|
||
B<Value:> 'auto', integer of distance, or arrayref of distance & thickness (more than one pair will provide mlultiple underlines. Negative distance gives strike-through.
|
||||
B<Default:> none
|
||||
| ca2ec834 | Sven Schöling | =item B<background_color> - Background color of this column
|

B<Value:> Color specifier as 'name' or 'HEX'

=item B<justify> - Alignment of text in this column
|

|
||||
{
|

|
||
| ca2ec834 | Sven Schöling | When this happens a warning will be issued with some advises what can be done.

In cases of a conflict between column formatting and odd/even row formatting, 'col_props' will override odd/even.

|
||
| 42b702a6 | Moritz Bunkus | |||
| ca2ec834 | Sven Schöling | Utility method to create a block of text. The block may contain multiple paragraphs.
|
||
| a5a81f46 | Moritz Bunkus | It is mainly used internaly but you can use it from outside for placing formatted text anywhere on the sheet.
|
||
| 42b702a6 | Moritz Bunkus | |||
| ca2ec834 | Sven Schöling | NOTE: This method will NOT add more pages to the pdf instance if the space is not enough to place the string inside the block.
|
||
Leftover text will be returned and has to be handled by the caller - i.e. add a new page and a new block with the leftover.
|
||||
=item Parameters
|
||||
$txt - a PDF::API2::Page::Text instance representing the text tool
|
||||
$data - a string that will be placed inside the block
|
||||
%settings - HASH with geometry and formatting parameters.

| ca2ec834 | Sven Schöling | |||
$width_of_last_line - Width of last line in the block
|
||||
$final_y - The Y coordinate of the block bottom so that additional content can be added after it
|

$left_over_text - Text that was did not fit in the provided box geometry.
