__construct() public method

It allows to set up the page format, the orientation and the units of measurement used in all the methods (except for the font sizes). Example:


$pdf = new Horde_Pdf_Writer(array('orientation' => 'P',
                                  'unit'   => 'mm',
                                  'format' => 'A4'));

public __construct ( array $params = [] )
$params	array	A hash with parameters for the created PDF object. Possible parameters are: - orientation - Default page orientation. Possible values are (case insensitive): - P or Portrait (default) - L or Landscape - unit - User measure units. Possible values values are: - pt: point - mm: millimeter (default) - cm: centimeter - in: inch A point equals 1/72 of inch, that is to say about 0.35 mm (an inch being 2.54 cm). This is a very common unit in typography; font sizes are expressed in that unit. - format - The format used for pages. It can be either one of the following values (case insensitive): - A3 - A4 (default) - A5 - Letter - Legal or a custom format in the form of a two-element array containing the width and the height (expressed in the unit given by the unit parameter).
