Methods

AddCoreFontMetrics()

Add a Core PDF Font

• Signature: protected function AddCoreFontMetrics($family,$style)

Parameters:

• string $family

AddPage()

Adds a new page to the document. If a page is already present, the Footer() method is called first to output the footer. Then the page is added, the current position set to the top-left corner according to the left and top margins, and Header() is called to display the header. The font which was set before calling is automatically restored. There is no need to call SetFont() again if you want to continue with the same font. The same is true for colors and line width. The origin of the coordinate system is at the top-left corner and increasing ordinates go downwards. @since 1.0 @see TCPDF(), Header(), Footer(), SetMargins()

Row has to be numeric sequential starting at 0. Column does not is already set, non null > 0 is the maximum table width

• 0: no border (default)
• 1: frame

Possible values are:

• 0: to the right
• 1: to the beginning of the next line [DEFAULT]
• 2: below

• Signature: public function MakeTable($text_table_data,$border,$max_table_width,$align_data,$header,$align_header,$ln)

Parameters:

SetAutoTableWidthStyle()

Set the alogorithm used to determine column widths

• Signature: public function SetAutoTableWidthStyle($style)

Parameters:

SetFont()

Sets the font used to print character strings. It is mandatory to call this method at least once before printing text or the resulting document would not be valid. The font can be either a standard one or a font added via the AddFont() method. Standard fonts use Windows encoding cp1252 (Western Europe). The method can be called before the first page is created and the font is retained from page to page. If you just wish to change the current font size, it is simpler to call SetFontSize().

Note: for the standard fonts, the font metric files must be accessible. There are three possibilities for this:

• They are in the current directory (the one where the running script lies)
• They are in one of the directories defined by the include_path parameter
• They are in the directory defined by the FPDF_FONTPATH constant

Example for the last case (note the trailing slash):

define('FPDF_FONTPATH','/home/www/font/');
require('tcpdf.php');

//Times regular 12
$pdf->SetFont('Times');
//Arial bold 14
$pdf->SetFont('Arial','B',14);
//Removes bold
$pdf->SetFont('');
//Times bold, italic and underlined 14
$pdf->SetFont('Times','BIU');

If the file corresponding to the requested font is not found, the error "Could not include font metric file" is generated. @since 1.0 @see AddFont(), SetFontSize(), Cell(), MultiCell(), Write()

• Signature: public function SetFont($family,$style,$size)

  • Symbol (symbolic)
  • ZapfDingbats (symbolic)
  It is also possible to pass an empty string. In that case, the current family is retained.
• string $style
  Font style. Possible values are (case insensitive):
  • empty string: regular
  • B: bold
  • I: italic
  • U: underline
  or any combination. The default value is regular. Bold and italic styles do not apply to Symbol and ZapfDingbats
  • Default Value:
