4451 * The method can be called before the first page is created and the font is retained from page to page.
4452 * If you just wish to change the current font size, it is simpler to call SetFontSize().
4453 * Note: for the standard fonts, the font metric files must be accessible. There are three possibilities for this:<ul><li>They are in the current directory (the one where the running script lies)</li><li>They are in one of the directories defined by the include_path parameter</li><li>They are in the directory defined by the K_PATH_FONTS constant</li></ul><br />
4454 * @param $family (string) Family font. It can be either a name defined by AddFont() or one of the standard Type1 families (case insensitive):<ul><li>times (Times-Roman)</li><li>timesb (Times-Bold)</li><li>timesi (Times-Italic)</li><li>timesbi (Times-BoldItalic)</li><li>helvetica (Helvetica)</li><li>helveticab (Helvetica-Bold)</li><li>helveticai (Helvetica-Oblique)</li><li>helveticabi (Helvetica-BoldOblique)</li><li>courier (Courier)</li><li>courierb (Courier-Bold)</li><li>courieri (Courier-Oblique)</li><li>courierbi (Courier-BoldOblique)</li><li>symbol (Symbol)</li><li>zapfdingbats (ZapfDingbats)</li></ul> It is also possible to pass an empty string. In that case, the current family is retained.
4455 * @param $style (string) Font style. Possible values are (case insensitive):<ul><li>empty string: regular</li><li>B: bold</li><li>I: italic</li><li>U: underline</li><li>D: line through</li><li>O: overline</li></ul> or any combination. The default value is regular. Bold and italic styles do not apply to Symbol and ZapfDingbats basic fonts or other fonts when not defined.
4456 * @param $size (float) Font size in points. The default value is the current size. If no size has been specified since the beginning of the document, the value taken is 12
4457 * @param $fontfile (string) The font definition file. By default, the name is built from the family and style, in lower case with no spaces.
4458 * @param $subset (mixed) if true embedd only a subset of the font (stores only the information related to the used characters); if false embedd full font; if 'default' uses the default value set using setFontSubsetting(). This option is valid only for TrueTypeUnicode fonts. If you want to enable users to change the document, set this parameter to false. If you subset the font, the person who receives your PDF would need to have your same font in order to make changes to your PDF. The file size of the PDF would also be smaller because you are embedding only part of a font.
4459 * @param $out (boolean) if true output the font size command, otherwise only set the font properties.

5765 * This method allows printing text with line breaks.
5766 * They can be automatic (as soon as the text reaches the right border of the cell) or explicit (via the \n character). As many cells as necessary are output, one below the other.<br />
5767 * Text can be aligned, centered or justified. The cell block can be framed and the background painted.
5768 * @param $w (float) Width of cells. If 0, they extend up to the right margin of the page.
5769 * @param $h (float) Cell minimum height. The cell extends automatically if needed.
5770 * @param $txt (string) String to print
5771 * @param $border (mixed) Indicates if borders must be drawn around the cell. The value can be a number:<ul><li>0: no border (default)</li><li>1: frame</li></ul> or a string containing some or all of the following characters (in any order):<ul><li>L: left</li><li>T: top</li><li>R: right</li><li>B: bottom</li></ul> or an array of line styles for each border group - for example: array('LTRB' => array('width' => 2, 'cap' => 'butt', 'join' => 'miter', 'dash' => 0, 'color' => array(0, 0, 0)))
5772 * @param $align (string) Allows to center or align the text. Possible values are:<ul><li>L or empty string: left align</li><li>C: center</li><li>R: right align</li><li>J: justification (default value when $ishtml=false)</li></ul>
5773 * @param $fill (boolean) Indicates if the cell background must be painted (true) or transparent (false).
5774 * @param $ln (int) Indicates where the current position should go after the call. Possible values are:<ul><li>0: to the right</li><li>1: to the beginning of the next line [DEFAULT]</li><li>2: below</li></ul>
5775 * @param $x (float) x position in user units
5776 * @param $y (float) y position in user units
5777 * @param $reseth (boolean) if true reset the last cell height (default true).
5778 * @param $stretch (int) font stretch mode: <ul><li>0 = disabled</li><li>1 = horizontal scaling only if text is larger than cell width</li><li>2 = forced horizontal scaling to fit cell width</li><li>3 = character spacing only if text is larger than cell width</li><li>4 = forced character spacing to fit cell width</li></ul> General font stretching and scaling values will be preserved when possible.
5779 * @param $ishtml (boolean) INTERNAL USE ONLY -- set to true if $txt is HTML content (default = false). Never set this parameter to true, use instead writeHTMLCell() or writeHTML() methods.
5780 * @param $autopadding (boolean) if true, uses internal padding and automatically adjust it to account for line width.
5781 * @param $maxh (float) maximum height. It should be >= $h and less then remaining space to the bottom of the page, or 0 for disable this feature. This feature works only when $ishtml=false.
5782 * @param $valign (string) Vertical alignment of text (requires $maxh = $h > 0). Possible values are:<ul><li>T: TOP</li><li>M: middle</li><li>B: bottom</li></ul>. This feature works only when $ishtml=false and the cell must fit in a single page.
5783 * @param $fitcell (boolean) if true attempt to fit all the text within the cell by reducing the font size (do not work in HTML mode). $maxh must be greater than 0 and wqual to $h.
5784 * @return int Return the number of cells or 1 for html mode.
5785 * @public
5786 * @since 1.3

22873 * NOTE: SVG standard is not yet fully implemented, use the setRasterizeVectorImages() method to enable/disable rasterization of vector images using ImageMagick library.
22874 * @param $file (string) Name of the SVG file or a '@' character followed by the SVG data string.
22875 * @param $x (float) Abscissa of the upper-left corner.
22876 * @param $y (float) Ordinate of the upper-left corner.
22877 * @param $w (float) Width of the image in the page. If not specified or equal to zero, it is automatically calculated.
22878 * @param $h (float) Height of the image in the page. If not specified or equal to zero, it is automatically calculated.
22879 * @param $link (mixed) URL or identifier returned by AddLink().
22880 * @param $align (string) Indicates the alignment of the pointer next to image insertion relative to image height. The value can be:<ul><li>T: top-right for LTR or top-left for RTL</li><li>M: middle-right for LTR or middle-left for RTL</li><li>B: bottom-right for LTR or bottom-left for RTL</li><li>N: next line</li></ul> If the alignment is an empty string, then the pointer will be restored on the starting SVG position.
22881 * @param $palign (string) Allows to center or align the image on the current line. Possible values are:<ul><li>L : left align</li><li>C : center</li><li>R : right align</li><li>'' : empty string : left for LTR or right for RTL</li></ul>
22882 * @param $border (mixed) Indicates if borders must be drawn around the cell. The value can be a number:<ul><li>0: no border (default)</li><li>1: frame</li></ul> or a string containing some or all of the following characters (in any order):<ul><li>L: left</li><li>T: top</li><li>R: right</li><li>B: bottom</li></ul> or an array of line styles for each border group - for example: array('LTRB' => array('width' => 2, 'cap' => 'butt', 'join' => 'miter', 'dash' => 0, 'color' => array(0, 0, 0)))

23887 * Sets the opening SVG element handler function for the XML parser. (*** TO BE COMPLETED ***)
23888 * @param $parser (resource) The first parameter, parser, is a reference to the XML parser calling the handler.
23889 * @param $name (string) The second parameter, name, contains the name of the element for which this handler is called. If case-folding is in effect for this parser, the element name will be in uppercase letters.
23890 * @param $attribs (array) The third parameter, attribs, contains an associative array with the element's attributes (if any). The keys of this array are the attribute names, the values are the attribute values. Attribute names are case-folded on the same criteria as element names. Attribute values are not case-folded. The original order of the attributes can be retrieved by walking through attribs the normal way, using each(). The first key in the array was the first attribute, and so on.
23891 * @param $ctm (array) tranformation matrix for clipping mode (starting transformation matrix).
