AddFont(string family [, string style [, string file]])

Ex. $pdf->AddFont('Comic','I','comici.php');
family : font family ex times new roman, comic, etc.
style : Bold, Italic, Underline
file : Name of file for font.

AddPage([string orientation])

orientation : Page orientation. Possible values are (case insensitive):

· P or Portrait

· L or Landscape
The default value is the one passed to the constructor

Cell(float w [, float h [, string txt [, mixed border [, int ln [, string align [, int fill [, mixed link]]]]]]])

w Cell width. If 0, the cell extends up to the right margin.

h Cell height. Default value: 0.

txt String to print. Default value: empty string.

Border Indicates if borders must be drawn around the cell. The value can be either a number:

· 0: no border

· 1: frame

or a string containing some or all of the following characters (in any order):

· L: left

· T: top

· R: right

· B: bottom

Default value: 0.

ln Indicates where the current position should go after the call. Possible values are:

· 0: to the right

· 1: to the beginning of the next line

· 2: below

Putting 1 is equivalent to putting 0 and calling Ln() just after. Default value: 0.

Align Allows to center or align the text. Possible values are:

· L or empty string: left align (default value)

· C: center

· R: right align

Fill Indicates if the cell background must be painted (1) or transparent (0). Default value: 0.

Link URL or identifier returned by AddLink().

Ex. $pdf->Cell(20,10,'Title',1,1,'C');

Close()

Close pdf document

AliasNbPages([string alias])

Defines an alias for the total number of pages. It will be substituted as the document is closed.

alias The alias. Default value: {nb}.

class PDF extends FPDF{

function Footer(){

//Go to 1.5 cm from bottom

$this->SetY(-15);

//Select Arial italic 8

$this->SetFont('Arial','I',8);

//Print current and total page numbers

$this->Cell(0,10,'Page '.$this->PageNo().'/{nb}',0,0,'C');

}

$pdf=new PDF();

$pdf->AliasNbPages();

Footer()

To set the footer

Ex. See above example

Header()

This method is used to render the page header. It is automatically called by AddPage() and should not be called directly by the application. The implementation in FPDF is empty, so you have to subclass it and override the method if you want a specific processing.

  class PDF extends FPDF{
      function Header(){
          //Select Arial bold 15
          $this->SetFont('Arial','B',15);
          //Move to the right
          $this->Cell(80);
          //Framed title
          $this->Cell(30,10,'Title',1,0,'C');
          //Line break
          $this->Ln(20);
      }
  }

Error(string msg)

This method is automatically called in case of fatal error; it simply outputs the message and halts the execution. An inherited class may override it to customize the error handling but should always halt the script, or the resulting document would probably be invalid.

FPDF([string orientation [, string unit [, mixed format]]])

This is the class constructor.It allows to set up the page format, the orientation and the measure unit used in all the methods (except for the font sizes).

  orientation   Default page orientation. Possible values are (case insensitive):
          ·         P or Portrait - Default
          ·         L or Landscape
  unit User measure unit. Possible 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
          ·         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 unit).

float GetStringWidth(string s)
  Returns the length of a string in user unit. A font must be selected.
  s    The string whose length is to be computed.

float GetX()
  Returns the abscissa of the current position.

float GetY()
  Returns the ordinate of the current position.

SetX(float x)

Defines the abscissa of the current position. If the passed value is negative, it is relative to the right of the page.

x The value of the abscissa.

SetY(float y)

Moves the current abscissa back to the left margin and sets the ordinate. If the passed value is negative, it is relative to the bottom of the page.

y The value of the ordinate.

SetXY(float x, float y)

Defines the abscissa and ordinate of the current position. If the passed values are negative, they are relative respectively to the right and bottom of the page.

Image(string file, float x, float y [, float w [, float h [, string type [, mixed link]]]])
  Puts an image in the page. The upper-left corner must be given. The dimensions can be specified in different ways:
  ·         explicit width and height (expressed in user unit)
  ·         one explicit dimension, the other being calculated automatically in order to keep the original proportions
  ·         no explicit dimension, in which case the image is put at 72 dpi
  Supported formats are JPEG and PNG.
  For JPEG, all flavors are allowed:
  ·         gray scales
  ·         true colors (24 bits)
  ·         CMYK (32 bits)
  For PNG, are allowed:
  ·         gray scales on at most 8 bits (256 levels)
  ·         indexed colors
  ·         true colors (24 bits)
  but are not supported:
   ·         Interlacing
  ·         Alpha channel

If a transparent color is defined, it will be taken into account (but will be only interpreted by Acrobat 4 and above). The format can be specified explicitly or inferred from the file extension. It is possible to put a link on the image.

Remark: if an image is used several times, only one copy will be embedded in the file.

  File Name of the file containing the image.
  x   Abscissa of the upper-left corner.
  y   Ordinate of the upper-left corner.
  w   Width of the image in the page. If not specified or equal to zero, it is automatically calculated.
  h   Height of the image in the page. If not specified or equal to zero, it is automatically calculated.
  Type Image format. Possible values are (case insensitive): JPG, JPEG, PNG. If not specified, the type is inferred from the file extension.
  Link URL or identifier returned by AddLink().

Line(float x1, float y1, float x2, float y2)
  Draws a line between two points.
  x1 Abscissa of first point.
  y1 Ordinate of first point.
  x2 Abscissa of second point.
  y2 Ordinate of second point.

Link(float x, float y, float w, float h, mixed link)

Puts a link on a rectangular area of the page. Text or image links are generally put via Cell(), Write() or Image(), but this method can be useful for instance to define a clickable area inside an image.

x Abscissa of the upper-left corner of the rectangle.

y Ordinate of the upper-left corner of the rectangle.

w Width of the rectangle.

h Height of the rectangle.

Link URL or identifier returned by AddLink().

Ln([float h])

Performs a line break. The current abscissa goes back to the left margin and the ordinate increases by the amount passed in parameter.

H The height of the break.

By default, the value equals the height of the last printed cell.

MultiCell(float w, float h, string txt [, mixed border [, string align [, int fill]]])

This method allows printing text with line breaks. 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.

Text can be aligned, centered or justified. The cell block can be framed and the background painted.

w Width of cells. If 0, they extend up to the right margin of the page.

h Height of cells.

txt String to print.

Border Indicates if borders must be drawn around the cell block. The value can be either a number:

· 0: no border - Default

· 1: frame

or a string containing some or all of the following characters (in any order):

· L: left

· T: top

· R: right

· B: bottom

Align Sets the text alignment. Possible values are:

· L: left alignment

· C: center

· R: right alignment

· J: justification - Default

Fill Indicates if the cell background must be painted (1) or transparent (0). Default value: 0.

Open()

This method begins the generation of the PDF document. It is not necessary to call it explicitly because AddPage() does it automatically.Note: no page is created by this method.

string Output([string name [, string dest]])

Send the document to a given destination: string, local file or browser. In the last case, the plug-in may be used (if present) or a download ("Save as" dialog box) may be forced.

The method first calls Close() if necessary to terminate the document.

Name The name of the file. If not given, the document will be sent to the browser (destination I) with the name doc.pdf.

Dest Destination where to send the document. It can take one of the following values:

· I: send the file inline to the browser. The plug-in is used if available.

· D: send to the browser and force a file download with the name given by name.

· F: save to a local file with the name given by name.

· S: return the document as a string. name is ignored.

If the parameter is not specified but a name is given, destination is F. If no parameter is specified at all, destination is I.

Note: for compatibility with previous versions, a boolean value is also accepted (false for F and true for D).

int PageNo()

Returns the current page number.

Rect(float x, float y, float w, float h [, string style])

Outputs a rectangle. It can be drawn (border only), filled (with no border) or both.

x Abscissa of upper-left corner.

y Ordinate of upper-left corner.

w Width.

h Height.

Style Style of rendering. Possible values are:

· D or empty string: draw. This is the default value.

· F: fill

· DF or FD: draw and fill

SetAuthor(string author)

Defines the author of the document.

Author The name of the author.

SetAutoPageBreak(boolean auto [, float margin])

Enables or disables the automatic page breaking mode. When enabling, the second parameter is the distance from the bottom of the page that defines the triggering limit. By default, the mode is on and the margin is 2 cm.

Auto Boolean indicating if mode should be on or off.

Margin Distance from the bottom of the page.

SetCompression(boolean compress)

Activates or deactivates page compression. When activated, the internal representation of each page is compressed, which leads to a compression ratio of about 2 for the resulting document.

Compression is on by default.

Note: the Zlib extension is required for this feature. If not present, compression will be turned off.

Compress Boolean indicating if compression must be enabled.

SetCreator(string creator)

Defines the creator of the document. This is typically the name of the application that generates the PDF.

Creator The name of the creator.

SetDisplayMode(mixed zoom [, string layout])

Defines the way the document is to be displayed by the viewer. The zoom level can be set: pages can be displayed entirely on screen, occupy the full width of the window, use real size, be scaled by a specific zooming factor or use viewer default (configured in the Preferences menu of Acrobat). The page layout can be specified too: single at once, continuous display, two columns or viewer default.

By default, documents use the full width mode with continuous display.

zoom The zoom to use. It can be one of the following string values:

· fullpage: displays the entire page on screen

· fullwidth: uses maximum width of window

· real: uses real size (equivalent to 100% zoom)

· default: uses viewer default mode

or a number indicating the zooming factor to use.

Layout The page layout. Possible values are:

· single: displays one page at once

· continuous: displays pages continuously - Default

· two: displays two pages on two columns

· default: uses viewer default mode

SetDrawColor(int r [, int g, int b])

Defines the color used for all drawing operations (lines, rectangles and cell borders). It can be expressed in RGB components or gray scale. The method can be called before the first page is created and the value is retained from page to page.

R If g et b are given, red component; if not, indicates the gray level. Value between 0 and 255.

G Green component (between 0 and 255).

B Blue component (between 0 and 255).

SetFillColor(int r [, int g, int b])

Defines the color used for all filling operations (filled rectangles and cell backgrounds). It can be expressed in RGB components or gray scale. The method can be called before the first page is created and the value is retained from page to page.

R If g and b are given, red component; if not, indicates the gray level. Value between 0 and 255.

G Green component (between 0 and 255).

B Blue component (between 0 and 255).

SetFont(string family [, string style [, float size]])

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('fpdf.php');

family Family font. It can be either a name defined by AddFont() or one of the standard families (case insensitive):

· Courier (fixed-width)

· Helvetica or Arial (synonymous; sans serif)

· Times (serif)

· Symbol (symbolic)

· ZapfDingbats (symbolic)

It is also possible to pass an empty string. In that case, the current family is retained.

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.

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.

//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');

SetFontSize(float size)

Defines the size of the current font.

Size The size (in points).

SetKeywords(string keywords)

Associates keywords with the document, generally in the form 'keyword1 keyword2 ...'.

Keywords The list of keywords.

SetLeftMargin(float margin)

Defines the left margin. The method can be called before creating the first page.

If the current abscissa gets out of page, it is brought back to the margin.

Margin The margin.

SetLineWidth(float width)

Defines the line width. By default, the value equals 0.2 mm. The method can be called before the first page is created and the value is retained from page to page.

width The width.

SetLink(int link [, float y [, int page]])

Defines the page and position a link points to.

Link The link identifier returned by AddLink().

Y Ordinate of target position; -1 indicates the current position. The default value is 0 (top of page).

Page Number of target page; -1 indicates the current page. This is the default value.

SetMargins(float left, float top [, float right])

Defines the left, top and right margins. By default, they equal 1 cm. Call this method to change them.

Left Left margin.

Top Top margin.

Right Right margin. Default value is the left one.

SetRightMargin(float margin)

Defines the right margin. The method can be called before creating the first page.

Margin The margin.

SetSubject(string subject)

Defines the subject of the document.

Subject The subject.

SetTextColor(int r [, int g, int b])

Defines the color used for text. It can be expressed in RGB components or gray scale. The method can be called before the first page is created and the value is retained from page to page.

r If g et b are given, red component; if not, indicates the gray level. Value between 0 and 255.

g Green component (between 0 and 255).

b Blue component (between 0 and 255).

SetTitle(string title)

Defines the title of the document.

Title The title.

SetTopMargin(float margin)

Defines the top margin. The method can be called before creating the first page.

Margin The margin.

Text(float x, float y, string txt)

Prints a character string. The origin is on the left of the first charcter, on the baseline. This method allows to place a string precisely on the page, but it is usually easier to use Cell(), MultiCell() or Write() which are the standard methods to print text.

x Abscissa of the origin.

y Ordinate of the origin.

txt String to print.

Write(float h, string txt [, mixed link])

This method prints text from the current position. When the right margin is reached (or the \n character is met) a line break occurs and text continues from the left margin. Upon method exit, the current position is left just at the end of the text.

It is possible to put a link on the text.

h Line height.

txt String to print.

link URL or identifier returned by AddLink().

//Begin with regular font$pdf->SetFont('Arial','',14);$pdf->Write(5,'Visit ');//Then put a blue underlined link$pdf->SetTextColor(0,0,255);$pdf->SetFont('','U');$pdf->Write(5,'www.fpdf.org','http://www.fpdf.org');
