Methods

AddCoreFontMetrics()

Add a Core PDF Font

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

AddFontByTTFFile()

  • Signature: public function AddFontByTTFFile($family,$style,$ttf_file)
  • Parameters:
  • $family
  • $style
  • $ttf_file

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.

  • Signature: public function AddPage($orientation)
  • Parameters:
    • string $orientation
      Page orientation. Possible values are (case insensitive):
      • P or Portrait

      The default value is the one passed to the constructor. @since 1.0 @see TCPDF(), Header(), Footer(), SetMargins()
      • Default Value:

Cell()

Row has to be numeric sequential starting at 0. Column does not

  • Signature: public function MakeTable($text_table_data,$border,$max_table_width,$align_data,$header,$align_header,$ln)
  • Parameters:
  • $text_table_data
    • mixed $border
      Indicates if borders must be drawn around the cell block. The value can be:
      • 0: no border (default)
      • 1: frame
      • Default Value: 0
    • numeric $max_table_width
      the maximum table width -- 0 fill the table to the right margin, null use the value as it is already set, non null > 0 is the maximum table width
      • Default Value: 0

  • Signature: public function SetAutoTableWidthStyle($style)
  • Parameters:
    • string $style
      Valid values are 'All', 'Header', and 'Explicit'

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.

  • Signature: public function SetFont($family,$style,$size)
  • Parameters:
    • string $family
      Family font. It can be either a name defined by AddFont() or one of the standard families (case insensitive):

      • Times (serif)
      • 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:
    • float $size
      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 @since 1.0 @see AddFont(), SetFontSize(), Cell(), MultiCell(), Write()
