		 * This is the class constructor.

		 * @since 1.0
		 * @param string $orientation page orientation. Possible values are (case insensitive):<ul><li>P or Portrait (default)</li><li>L or Landscape</li></ul>
		 * @param string $unit User measure unit. Possible values are:<ul><li>pt: point</li><li>mm: millimeter (default)</li><li>cm: centimeter</li><li>in: inch</li></ul><br />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.
		 * @param mixed $format The format used for pages. It can be either one of the following values (case insensitive) or a custom format in the form of a two-element array containing the width and the height (expressed in the unit given by unit).<ul><li>4A0</li><li>2A0</li><li>A0</li><li>A1</li><li>A2</li><li>A3</li><li>A4 (default)</li><li>A5</li><li>A6</li><li>A7</li><li>A8</li><li>A9</li><li>A10</li><li>B0</li><li>B1</li><li>B2</li><li>B3</li><li>B4</li><li>B5</li><li>B6</li><li>B7</li><li>B8</li><li>B9</li><li>B10</li><li>C0</li><li>C1</li><li>C2</li><li>C3</li><li>C4</li><li>C5</li><li>C6</li><li>C7</li><li>C8</li><li>C9</li><li>C10</li><li>RA0</li><li>RA1</li><li>RA2</li><li>RA3</li><li>RA4</li><li>SRA0</li><li>SRA1</li><li>SRA2</li><li>SRA3</li><li>SRA4</li><li>LETTER</li><li>LEGAL</li><li>EXECUTIVE</li><li>FOLIO</li></ul>
