+<ul id='answers'>

+<li id='q1'>

+<p><b>1.</b> <span class='question'>What's exactly the license of FPDF? Are there any usage restrictions?</span></p>

+FPDF is released under a permissive license: there is no usage restriction. You may embed it

+freely in your application (commercial or not), with or without modifications.

+</li>

+

+<li id='q2'>

+<p><b>2.</b> <span class='question'>When I try to create a PDF, a lot of weird characters show on the screen. Why?</span></p>

+These "weird" characters are in fact the actual content of your PDF. This behavior is a bug of

+IE6. When it first receives an HTML page, then a PDF from the same URL, it displays it directly

+without launching Acrobat. This happens frequently during the development stage: on the least

+script error, an HTML page is sent, and after correction, the PDF arrives.

+<br>

+To solve the problem, simply quit and restart IE. You can also go to another URL and come

+back.

+<br>

+To avoid this kind of inconvenience during the development, you can generate the PDF directly

+to a file and open it through the explorer.

+</li>

+

+<li id='q3'>

+<p><b>3.</b> <span class='question'>I try to generate a PDF and IE displays a blank page. What happens?</span></p>

+First of all, check that you send nothing to the browser after the PDF (not even a space or a

+carriage return). You can put an exit statement just after the call to the Output() method to

+be sure. If it still doesn't work, it means you're a victim of the "blank page syndrome". IE

+used in conjunction with the Acrobat plug-in suffers from many bugs. To avoid these problems

+in a reliable manner, two main techniques exist:

+<br>

+<br>

+- Disable the plug-in and use Acrobat as a helper application. To do this, launch Acrobat, go

+to the Edit menu, Preferences, Internet, and uncheck "Display PDF in browser". Then, the next

+time you load a PDF in IE, it displays the dialog box "Open it" or "Save it to disk". Uncheck

+the option "Always ask before opening this type of file" and choose Open. From now on, PDF files

+will open automatically in an external Acrobat window.

+<br>

+The drawback of the method is that you need to alter the client configuration, which you can do

+in an intranet environment but not for the Internet.

+<br>

+<br>

+- Use a redirection technique. It consists in generating the PDF in a temporary file on the server

+and redirect the client to it. For example, at the end of the script, you can put the following:

+<div class="doc-source">

+<pre><code>//Determine a temporary file name in the current directory

+$file = basename(tempnam('.', 'tmp'));

+rename($file, $file.'.pdf');

+$file .= '.pdf';

+//Save PDF to file

+$pdf-&gt;Output($file, 'F');

+//Redirect

+header('Location: '.$file);</code></pre>

+</div>

+This method turns the dynamic PDF into a static one and avoids all troubles. But you have to do

+some cleaning in order to delete the temporary files. For example:

+<div class="doc-source">

+<pre><code>function CleanFiles($dir)

+{

+    //Delete temporary files

+    $t = time();

+    $h = opendir($dir);

+    while($file=readdir($h))

+    {

+        if(substr($file,0,3)=='tmp' &amp;&amp; substr($file,-4)=='.pdf')

+        {

+            $path = $dir.'/'.$file;

+            if($t-filemtime($path)&gt;3600)

+                @unlink($path);

+        }

+    }

+    closedir($h);

+}</code></pre>

+</div>

+This function deletes all files of the form tmp*.pdf older than an hour in the specified

+directory. You may call it where you want, for example in the script which generates the PDF.

+</li>

+

+<li id='q4'>

+<p><b>4.</b> <span class='question'>I can't make line breaks work. I put \n in the string printed by MultiCell but it doesn't work.</span></p>

+You have to enclose your string with double quotes, not single ones.

+</li>

+

+<li id='q5'>

+<p><b>5.</b> <span class='question'>I try to display a variable in the Header method but nothing prints.</span></p>

+You have to use the <code>global</code> keyword to access global variables, for example:

+<div class="doc-source">

+<pre><code>function Header()

+{

+    global $title;

+

+    $this-&gt;SetFont('Arial', 'B', 15);

+    $this-&gt;Cell(0, 10, $title, 1, 1, 'C');

+}

+

+$title = 'My title';</code></pre>

+</div>

+Alternatively, you can use an object property:

+<div class="doc-source">

+<pre><code>function Header()

+{

+    $this-&gt;SetFont('Arial', 'B', 15);

+    $this-&gt;Cell(0, 10, $this-&gt;title, 1, 1, 'C');

+}

+

+$pdf-&gt;title = 'My title';</code></pre>

+</div>

+</li>

+

+<li id='q6'>

+<p><b>6.</b> <span class='question'>I defined the Header and Footer methods in my PDF class but nothing appears.</span></p>

+You have to create an object from the PDF class, not FPDF:

+<div class="doc-source">

+<pre><code>$pdf = new PDF();</code></pre>

+</div>

+</li>

+

+<li id='q7'>

+<p><b>7.</b> <span class='question'>Accented characters are replaced by some strange characters like é.</span></p>

+Don't use UTF-8 encoding. Standard FPDF fonts use ISO-8859-1 or Windows-1252.

+It is possible to perform a conversion to ISO-8859-1 with utf8_decode():

+<div class="doc-source">

+<pre><code>$str = utf8_decode($str);</code></pre>

+</div>

+But some characters such as Euro won't be translated correctly. If the iconv extension is available, the

+right way to do it is the following:

+<div class="doc-source">

+<pre><code>$str = iconv('UTF-8', 'windows-1252', $str);</code></pre>

+</div>

+</li>

+

+<li id='q8'>

+<p><b>8.</b> <span class='question'>I try to display the Euro symbol but it doesn't work.</span></p>

+The standard fonts have the Euro character at position 128. You can define a constant like this

+for convenience:

+<div class="doc-source">

+<pre><code>define('EURO', chr(128));</code></pre>

+</div>

+</li>

+

+<li id='q9'>

+<p><b>9.</b> <span class='question'>I get the following error when I try to generate a PDF: Some data has already been output, can't send PDF file</span></p>

+You must send nothing to the browser except the PDF itself: no HTML, no space, no carriage return. A common

+case is having extra blank at the end of an included script file.<br>

+If you can't figure out where the problem comes from, this other message appearing just before can help you:<br>

+<br>

+<b>Warning:</b> Cannot modify header information - headers already sent by (output started at script.php:X)<br>

+<br>

+It means that script.php outputs something at line X. Go to this line and fix it.

+In case the message doesn't show, first check that you didn't disable warnings, then add this at the very

+beginning of your script:

+<div class="doc-source">

+<pre><code>ob_end_clean();</code></pre>

+</div>

+If you still don't see it, disable zlib.output_compression in your php.ini and it should appear.

+</li>

+

+<li id='q10'>

+<p><b>10.</b> <span class='question'>I draw a frame with very precise dimensions, but when printed I notice some differences.</span></p>

+To respect dimensions, select "None" for the Page Scaling setting instead of "Shrink to Printable Area" in the print dialog box.

+</li>

+

+<li id='q11'>

+<p><b>11.</b> <span class='question'>I'd like to use the whole surface of the page, but when printed I always have some margins. How can I get rid of them?</span></p>

+Printers have physical margins (different depending on the models); it is therefore impossible to remove

+them and print on the whole surface of the paper.

+</li>

+

+<li id='q12'>

+<p><b>12.</b> <span class='question'>How can I put a background in my PDF?</span></p>

+For a picture, call Image() in the Header() method, before any other output. To set a background color, use Rect().

+</li>

+

+<li id='q13'>

+<p><b>13.</b> <span class='question'>How can I set a specific header or footer on the first page?</span></p>

+Simply test the page number:

+<div class="doc-source">

+<pre><code>function Header()

+{

+    if($this-&gt;PageNo()==1)

+    {

+        //First page

+        ...

+    }

+    else

+    {

+        //Other pages

+        ...

+    }

+}</code></pre>

+</div>

+</li>

+

+<li id='q14'>

+<p><b>14.</b> <span class='question'>I'd like to use extensions provided by different scripts. How can I combine them?</span></p>

+Use an inheritance chain. If you have two classes, say A in a.php:

+<div class="doc-source">

+<pre><code>require('fpdf.php');

+

+class A extends FPDF

+{

+...

+}</code></pre>

+</div>

+and B in b.php:

+<div class="doc-source">

+<pre><code>require('fpdf.php');

+

+class B extends FPDF

+{

+...

+}</code></pre>

+</div>

+then make B extend A:

+<div class="doc-source">

+<pre><code>require('a.php');

+

+class B extends A

+{

+...

+}</code></pre>

+</div>

+and make your own class extend B:

+<div class="doc-source">

+<pre><code>require('b.php');

+

+class PDF extends B

+{

+...

+}

+

+$pdf = new PDF();</code></pre>

+</div>

+</li>

+

+<li id='q15'>

+<p><b>15.</b> <span class='question'>How can I send the PDF by email?</span></p>

+As any other file, but an easy way is to use <a href="http://phpmailer.codeworxtech.com">PHPMailer</a> and

+its in-memory attachment:

+<div class="doc-source">

+<pre><code>$mail = new PHPMailer();

+...

+$doc = $pdf-&gt;Output('', 'S');

+$mail-&gt;AddStringAttachment($doc, 'doc.pdf', 'base64', 'application/pdf');

+$mail-&gt;Send();</code></pre>

+</div>

+</li>

+

+<li id='q16'>

+<p><b>16.</b> <span class='question'>What's the limit of the file sizes I can generate with FPDF?</span></p>

+There is no particular limit. There are some constraints, however:

+<br>

+<br>

+- The maximum memory size allocated to PHP scripts is usually 8MB. For very big documents,

+especially with images, this limit may be reached (the file being built into memory). The

+parameter is configured in the php.ini file.

+<br>

+<br>

+- The maximum execution time allocated defaults to 30 seconds. This limit can of course be easily

+reached. It is configured in php.ini and may be altered dynamically with set_time_limit().

+<br>

+<br>

+- Browsers generally have a 5 minute time-out. If you send the PDF directly to the browser and

+reach the limit, it will be lost. It is therefore advised for very big documents to

+generate them in a file, and to send some data to the browser from time to time (with a call

+to flush() to force the output). When the document is finished, you can send a redirection to

+it or create a link.

+<br>

+Remark: even if the browser times out, the script may continue to run on the server.

+

+<li id='q17'>

+<p><b>17.</b> <span class='question'>Can I modify a PDF with FPDF?</span></p>

+It is possible to import pages from an existing PDF document thanks to the FPDI extension:<br>

+<br>

+<a href="http://www.setasign.de/products/pdf-php-solutions/fpdi/" target="_blank">http://www.setasign.de/products/pdf-php-solutions/fpdi/</a><br>

+<br>

+You can then add some content to them.

+

+<li id='q18'>

+<p><b>18.</b> <span class='question'>I'd like to make a search engine in PHP and index PDF files. Can I do it with FPDF?</span></p>

+No. But a GPL C utility does exist, pdftotext, which is able to extract the textual content from

+a PDF. It is provided with the Xpdf package:<br>

+<br>

+<a href="http://www.foolabs.com/xpdf/" target="_blank">http://www.foolabs.com/xpdf/</a>

+</li>

+

+<li id='q19'>

+<p><b>19.</b> <span class='question'>Can I convert an HTML page to PDF with FPDF?</span></p>

+Not real-world pages. But a GPL C utility does exist, htmldoc, which allows to do it and gives good results:<br>

+<br>

+<a href="http://www.htmldoc.org" target="_blank">http://www.htmldoc.org</a>

+</li>

+

+<li id='q20'>

+<p><b>20.</b> <span class='question'>Can I concatenate PDF files with FPDF?</span></p>

+Not directly, but it is possible to use <a href="http://www.setasign.de/products/pdf-php-solutions/fpdi/demos/concatenate-fake/" target="_blank">FPDI</a>

+to perform this task. Some free command-line tools also exist:<br>

+<h1>AcceptPageBreak</h1>

+<code><b>boolean</b> AcceptPageBreak()</code>

+<h2>Description</h2>

+Whenever a page break condition is met, the method is called, and the break is issued or not

+depending on the returned value. The default implementation returns a value according to the

+mode selected by SetAutoPageBreak().

+<br>

+This method is called automatically and should not be called directly by the application.

+<h2>Example</h2>

+The method is overriden in an inherited class in order to obtain a 3 column layout:

+<div class="doc-source">

+<pre><code>class PDF extends FPDF

+{

+var $col = 0;

+

+function SetCol($col)

+{

+    // Move position to a column

+    $this-&gt;col = $col;

+    $x = 10+$col*65;

+    $this-&gt;SetLeftMargin($x);

+    $this-&gt;SetX($x);

+}

+

+function AcceptPageBreak()

+{

+    if($this-&gt;col&lt;2)

+    {

+        // Go to next column

+        $this-&gt;SetCol($this-&gt;col+1);

+        $this-&gt;SetY(10);

+        return false;

+    }

+    else

+    {

+        // Go back to first column and issue page break

+        $this-&gt;SetCol(0);

+        return true;

+    }

+}

+}

+

+$pdf = new PDF();

+$pdf-&gt;AddPage();

+$pdf-&gt;SetFont('Arial','',12);

+for($i=1;$i&lt;=300;$i++)

+<h1>AddFont</h1>

+<code>AddFont(<b>string</b> family [, <b>string</b> style [, <b>string</b> file]])</code>

+<h2>Description</h2>

+Imports a TrueType, OpenType or Type1 font and makes it available. It is necessary to generate a font

+definition file first with the MakeFont utility.

+<br>

+The definition file (and the font file itself when embedding) must be present in the font directory.

+If it is not found, the error "Could not include font definition file" is raised.

+<h2>Parameters</h2>

+<dl class="param">

+<dt><code>family</code></dt>

+<dd>

+Font family. The name can be chosen arbitrarily. If it is a standard family name, it will

+override the corresponding font.

+</dd>

+<dt><code>style</code></dt>

+<dd>

+Font style. Possible values are (case insensitive):

+<ul>

+<li>empty string: regular</li>

+<li><code>B</code>: bold</li>

+<li><code>I</code>: italic</li>

+<li><code>BI</code> or <code>IB</code>: bold italic</li>

+</ul>

+The default value is regular.

+</dd>

+<dt><code>file</code></dt>

+<dd>

+The font definition file.

+<br>

+By default, the name is built from the family and style, in lower case with no space.

+</dd>

+</dl>

+<h2>Example</h2>

+<div class="doc-source">

+<pre><code>$pdf-&gt;AddFont('Comic','I');</code></pre>

+</div>

+is equivalent to:

+<div class="doc-source">

+<pre><code>$pdf-&gt;AddFont('Comic','I','comici.php');</code></pre>

+<h1>AddPage</h1>

+<code>AddPage([<b>string</b> orientation [, <b>mixed</b> size]])</code>

+<h2>Description</h2>

+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.

+<br>

+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.

+<br>

+The origin of the coordinate system is at the top-left corner and increasing ordinates go

+downwards.

+<h2>Parameters</h2>

+<dl class="param">

+<dt><code>orientation</code></dt>

+<dd>

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

+<ul>

+<li><code>P</code> or <code>Portrait</code></li>

+<li><code>L</code> or <code>Landscape</code></li>

+<h2>Parameters</h2>

+<dl class="param">

+<dt><code>orientation</code></dt>

+<dd>

+Default page orientation. Possible values are (case insensitive):

+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.

+<br>

+<br>

+Default value is <code>mm</code>.

+</dd>

+<dt><code>size</code></dt>

+<dd>

+The size used for pages. It can be either one of the following values (case insensitive):

+<ul>

+<li><code>A3</code></li>

+<code>Image(<b>string</b> file [, <b>float</b> x [, <b>float</b> y [, <b>float</b> w [, <b>float</b> h [, <b>string</b> type [, <b>mixed</b> link]]]]]])</code>

+<h2>Description</h2>

+Puts an image. The size it will take on the page can be specified in different ways:

+<ul>

+<li>explicit width and height (expressed in user unit or dpi)</li>

+<li>one explicit dimension, the other being calculated automatically in order to keep the original proportions</li>

+<li>no explicit dimension, in which case the image is put at 96 dpi</li>

+</ul>

+Supported formats are JPEG, PNG and GIF. The GD extension is required for GIF.

+<br>

+<br>

+For JPEGs, all flavors are allowed:

+<ul>

+<li>gray scales</li>

+<li>true colors (24 bits)</li>

+<li>CMYK (32 bits)</li>

+</ul>

+For PNGs, are allowed:

+<ul>

+<li>gray scales on at most 8 bits (256 levels)</li>

+<li>indexed colors</li>

+<li>true colors (24 bits)</li>

+</ul>

+For GIFs: in case of an animated GIF, only the first frame is displayed.<br>

+<br>

+Transparency is supported.<br>

+<br>

+The format can be specified explicitly or inferred from the file extension.<br>

+<br>

+It is possible to put a link on the image.<br>

+<br>

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

+<h2>Parameters</h2>

+<dl class="param">

+<dt><code>file</code></dt>

+<dd>

+Path or URL of the image.

+</dd>

+<dt><code>x</code></dt>

+<dd>

+Abscissa of the upper-left corner. If not specified or equal to <code>null</code>, the current abscissa

+is used.

+</dd>

+<dt><code>y</code></dt>

+<dd>

+Ordinate of the upper-left corner. If not specified or equal to <code>null</code>, the current ordinate

+is used; moreover, a page break is triggered first if necessary (in case automatic page breaking is enabled)

+and, after the call, the current ordinate is moved to the bottom of the image.

+</dd>

+<dt><code>w</code></dt>

+<dd>

+Width of the image in the page. There are three cases:

+<ul>

+<li>If the value is positive, it represents the width in user unit</li>

+<li>If the value is negative, the absolute value represents the horizontal resolution in dpi</li>

+<li>If the value is not specified or equal to zero, it is automatically calculated</li>

+</ul>

+</dd>

+<dt><code>h</code></dt>

+<dd>

+Height of the image in the page. There are three cases:

+<ul>

+<li>If the value is positive, it represents the height in user unit</li>

+<li>If the value is negative, the absolute value represents the vertical resolution in dpi</li>

+<li>If the value is not specified or equal to zero, it is automatically calculated</li>

+</ul>

+</dd>

+<dt><code>type</code></dt>

+<dd>

+Image format. Possible values are (case insensitive): <code>JPG</code>, <code>JPEG</code>, <code>PNG</code> and <code>GIF</code>.

+If not specified, the type is inferred from the file extension.

+</dd>

+<dt><code>link</code></dt>

+<dd>

+URL or identifier returned by AddLink().

+</dd>

+</dl>

+<h2>Example</h2>

+<div class="doc-source">

+<pre><code>// Insert a logo in the top-left corner at 300 dpi

+$pdf-&gt;Image('logo.png',10,10,-300);

+// Insert a dynamic image from a URL

+$pdf-&gt;Image('http://chart.googleapis.com/chart?cht=p3&amp;chd=t:60,40&amp;chs=250x100&amp;chl=Hello|World',60,30,90,0,'PNG');</code></pre>

+<h1>SetFont</h1>

+<code>SetFont(<b>string</b> family [, <b>string</b> style [, <b>float</b> size]])</code>

+<h2>Description</h2>

+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.

+<br>

+The font can be either a standard one or a font added via the AddFont() method. Standard fonts

+use the Windows encoding cp1252 (Western Europe).

+<br>

+The method can be called before the first page is created and the font is kept from page

+to page.

+<br>

+If you just wish to change the current font size, it is simpler to call SetFontSize().

+<br>

+<br>

+<strong>Note:</strong> the font definition files must be accessible. They are searched successively in:

+<ul>

+<li>The directory defined by the <code>FPDF_FONTPATH</code> constant (if this constant is defined)</li>

+<li>The <code>font</code> directory located in the same directory as <code>fpdf.php</code> (if it exists)</li>

+<li>The directories accessible through <code>include()</code></li>

+</ul>

+Example using <code>FPDF_FONTPATH</code>:

+<div class="doc-source">

+<pre><code>define('FPDF_FONTPATH','/home/www/font');

+require('fpdf.php');</code></pre>

+</div>

+If the file corresponding to the requested font is not found, the error "Could not include font

+definition file" is raised.

+<h2>Parameters</h2>

+<dl class="param">

+<dt><code>family</code></dt>

+<dd>

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

+insensitive):

+<ul>

+<li><code>Courier</code> (fixed-width)</li>

+<li><code>Helvetica</code> or <code>Arial</code> (synonymous; sans serif)</li>

+<li><code>Times</code> (serif)</li>

+<li><code>Symbol</code> (symbolic)</li>

+<li><code>ZapfDingbats</code> (symbolic)</li>

+</ul>

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

+</dd>

+<dt><code>style</code></dt>

+<dd>

+Font style. Possible values are (case insensitive):

+<ul>

+<li>empty string: regular</li>

+<li><code>B</code>: bold</li>

+<li><code>I</code>: italic</li>

+<li><code>U</code>: underline</li>

+</ul>

+or any combination. The default value is regular.

+Bold and italic styles do not apply to <code>Symbol</code> and <code>ZapfDingbats</code>.

+</dd>

+<dt><code>size</code></dt>

+<dd>

+Font size in points.

+<br>

+The default value is the current size. If no size has been specified since the beginning of

+the document, the value taken is 12.

+</dd>

+</dl>

+<h2>Example</h2>

+<div class="doc-source">

+<pre><code>// Times regular 12

+$pdf-&gt;SetFont('Times');

+// Arial bold 14

+$pdf-&gt;SetFont('Arial','B',14);

+// Removes bold

+$pdf-&gt;SetFont('');

+// Times bold, italic and underlined 14

+$pdf-&gt;SetFont('Times','BIU');</code></pre>

+The year 1866 was marked by a bizarre development, an unexplained and downright inexplicable phenomenon that surely no one has forgotten. Without getting into those rumors that upset civilians in the seaports and deranged the public mind even far inland, it must be said that professional seamen were especially alarmed. Traders, shipowners, captains of vessels, skippers, and master mariners from Europe and America, naval officers from every country, and at their heels the various national governments on these two continents, were all extremely disturbed by the business.

+In essence, over a period of time several ships had encountered "an enormous thing" at sea, a long spindle-shaped object, sometimes giving off a phosphorescent glow, infinitely bigger and faster than any whale.

+The relevant data on this apparition, as recorded in various logbooks, agreed pretty closely as to the structure of the object or creature in question, its unprecedented speed of movement, its startling locomotive power, and the unique vitality with which it seemed to be gifted.  If it was a cetacean, it exceeded in bulk any whale previously classified by science.  No naturalist, neither Cuvier nor Lacépède, neither Professor Dumeril nor Professor de Quatrefages, would have accepted the existence of such a monster sight unseen -- specifically, unseen by their own scientific eyes.

+Striking an average of observations taken at different times -- rejecting those timid estimates that gave the object a length of 200 feet, and ignoring those exaggerated views that saw it as a mile wide and three long--you could still assert that this phenomenal creature greatly exceeded the dimensions of anything then known to ichthyologists, if it existed at all.

+Now then, it did exist, this was an undeniable fact; and since the human mind dotes on objects of wonder, you can understand the worldwide excitement caused by this unearthly apparition. As for relegating it to the realm of fiction, that charge had to be dropped.

+In essence, on July 20, 1866, the steamer Governor Higginson, from the Calcutta & Burnach Steam Navigation Co., encountered this moving mass five miles off the eastern shores of Australia. Captain Baker at first thought he was in the presence of an unknown reef; he was even about to fix its exact position when two waterspouts shot out of this inexplicable object and sprang hissing into the air some 150 feet.  So, unless this reef was subject to the intermittent eruptions of a geyser, the Governor Higginson had fair and honest dealings with some aquatic mammal, until then unknown, that could spurt from its blowholes waterspouts mixed with air and steam.

+Similar events were likewise observed in Pacific seas, on July 23 of the same year, by the Christopher Columbus from the West India & Pacific Steam Navigation Co.  Consequently, this extraordinary cetacean could transfer itself from one locality to another with startling swiftness, since within an interval of just three days, the Governor Higginson and the Christopher Columbus had observed it at two positions on the charts separated by a distance of more than 700 nautical leagues.

+Fifteen days later and 2,000 leagues farther, the Helvetia from the Compagnie Nationale and the Shannon from the Royal Mail line, running on opposite tacks in that part of the Atlantic lying between the United States and Europe, respectively signaled each other that the monster had been sighted in latitude 42 degrees 15' north and longitude 60 degrees 35' west of the meridian of Greenwich.  From their simultaneous observations, they were able to estimate the mammal's minimum length at more than 350 English feet; this was because both the Shannon and the Helvetia were of smaller dimensions, although each measured 100 meters stem to stern. Now then, the biggest whales, those rorqual whales that frequent the waterways of the Aleutian Islands, have never exceeded a length of 56 meters--if they reach even that.

+One after another, reports arrived that would profoundly affect public opinion:  new observations taken by the transatlantic liner Pereire, the Inman line's Etna running afoul of the monster, an official report drawn up by officers on the French frigate Normandy, dead-earnest reckonings obtained by the general staff of Commodore Fitz-James aboard the Lord Clyde. In lighthearted countries, people joked about this phenomenon, but such serious, practical countries as England, America, and Germany were deeply concerned.

+In every big city the monster was the latest rage; they sang about it in the coffee houses, they ridiculed it in the newspapers, they dramatized it in the theaters.  The tabloids found it a fine opportunity for hatching all sorts of hoaxes. In those newspapers short of copy, you saw the reappearance of every gigantic imaginary creature, from "Moby Dick," that dreadful white whale from the High Arctic regions, to the stupendous kraken whose tentacles could entwine a 500-ton craft and drag it into the ocean depths. They even reprinted reports from ancient times: the views of Aristotle and Pliny accepting the existence of such monsters, then the Norwegian stories of Bishop Pontoppidan, the narratives of Paul Egede, and finally the reports of Captain Harrington -- whose good faith is above suspicion--in which he claims he saw, while aboard the Castilian in 1857, one of those enormous serpents that, until then, had frequented only the seas of France's old extremist newspaper, The Constitutionalist.

+During the period in which these developments were occurring, I had returned from a scientific undertaking organized to explore the Nebraska badlands in the United States. In my capacity as Assistant Professor at the Paris Museum of Natural History, I had been attached to this expedition by the French government. After spending six months in Nebraska, I arrived in New York laden with valuable collections near the end of March. My departure for France was set for early May. In the meantime, then, I was busy classifying my mineralogical, botanical, and zoological treasures when that incident took place with the Scotia.

+I was perfectly abreast of this question, which was the big news of the day, and how could I not have been? I had read and reread every American and European newspaper without being any farther along. This mystery puzzled me. Finding it impossible to form any views, I drifted from one extreme to the other. Something was out there, that much was certain, and any doubting Thomas was invited to place his finger on the Scotia's wound.

+When I arrived in New York, the question was at the boiling point. The hypothesis of a drifting islet or an elusive reef, put forward by people not quite in their right minds, was completely eliminated. And indeed, unless this reef had an engine in its belly, how could it move about with such prodigious speed?

+Also discredited was the idea of a floating hull or some other enormous wreckage, and again because of this speed of movement.

+So only two possible solutions to the question were left, creating two very distinct groups of supporters: on one side, those favoring a monster of colossal strength; on the other, those favoring an "underwater boat" of tremendous motor power.

+Now then, although the latter hypothesis was completely admissible, it couldn't stand up to inquiries conducted in both the New World and the Old. That a private individual had such a mechanism at his disposal was less than probable. Where and when had he built it, and how could he have built it in secret?

+Only some government could own such an engine of destruction, and in these disaster-filled times, when men tax their ingenuity to build increasingly powerful aggressive weapons, it was possible that, unknown to the rest of the world, some nation could have been testing such a fearsome machine. The Chassepot rifle led to the torpedo, and the torpedo has led to this underwater battering ram, which in turn will lead to the world putting its foot down. At least I hope it will.

+But this hypothesis of a war machine collapsed in the face of formal denials from the various governments. Since the public interest was at stake and transoceanic travel was suffering, the sincerity of these governments could not be doubted. Besides, how could the assembly of this underwater boat have escaped public notice? Keeping a secret under such circumstances would be difficult enough for an individual, and certainly impossible for a nation whose every move is under constant surveillance by rival powers.

+So, after inquiries conducted in England, France, Russia, Prussia, Spain, Italy, America, and even Turkey, the hypothesis of an underwater Monitor was ultimately rejected.

+After I arrived in New York, several people did me the honor of consulting me on the phenomenon in question. In France I had published a two-volume work, in quarto, entitled The Mysteries of the Great Ocean Depths. Well received in scholarly circles, this book had established me as a specialist in this pretty obscure field of natural history. My views were in demand. As long as I could deny the reality of the business, I confined myself to a flat "no comment." But soon, pinned to the wall, I had to explain myself straight out. And in this vein, "the honorable Pierre Aronnax, Professor at the Paris Museum," was summoned by The New York Herald to formulate his views no matter what.

+I complied. Since I could no longer hold my tongue, I let it wag. I discussed the question in its every aspect, both political and scientific, and this is an excerpt from the well-padded article I published in the issue of April 30.

+

+"Therefore," I wrote, "after examining these different hypotheses one by one, we are forced, every other supposition having been refuted, to accept the existence of an extremely powerful marine animal.

+"The deepest parts of the ocean are totally unknown to us. No soundings have been able to reach them. What goes on in those distant depths? What creatures inhabit, or could inhabit, those regions twelve or fifteen miles beneath the surface of the water? What is the constitution of these animals? It's almost beyond conjecture.

+"However, the solution to this problem submitted to me can take the form of a choice between two alternatives.

+"Either we know every variety of creature populating our planet, or we do not.

+"If we do not know every one of them, if nature still keeps ichthyological secrets from us, nothing is more admissible than to accept the existence of fish or cetaceans of new species or even new genera, animals with a basically 'cast-iron' constitution that inhabit strata beyond the reach of our soundings, and which some development or other, an urge or a whim if you prefer, can bring to the upper level of the ocean for long intervals.

+"If, on the other hand, we do know every living species, we must look for the animal in question among those marine creatures already cataloged, and in this event I would be inclined to accept the existence of a giant narwhale.

+"The common narwhale, or sea unicorn, often reaches a length of sixty feet. Increase its dimensions fivefold or even tenfold, then give this cetacean a strength in proportion to its size while enlarging its offensive weapons, and you have the animal we're looking for. It would have the proportions determined by the officers of the Shannon, the instrument needed to perforate the Scotia, and the power to pierce a steamer's hull.

+"In essence, the narwhale is armed with a sort of ivory sword, or lance, as certain naturalists have expressed it. It's a king-sized tooth as hard as steel. Some of these teeth have been found buried in the bodies of baleen whales, which the narwhale attacks with invariable success. Others have been wrenched, not without difficulty, from the undersides of vessels that narwhales have pierced clean through, as a gimlet pierces a wine barrel. The museum at the Faculty of Medicine in Paris owns one of these tusks with a length of 2.25 meters and a width at its base of forty-eight centimeters!

+"All right then! Imagine this weapon to be ten times stronger and the animal ten times more powerful, launch it at a speed of twenty miles per hour, multiply its mass times its velocity, and you get just the collision we need to cause the specified catastrophe.

+"So, until information becomes more abundant, I plump for a sea unicorn of colossal dimensions, no longer armed with a mere lance but with an actual spur, like ironclad frigates or those warships called 'rams,' whose mass and motor power it would possess simultaneously.

+"This inexplicable phenomenon is thus explained away--unless it's something else entirely, which, despite everything that has been sighted, studied, explored and experienced, is still possible!"

+<body>

+<h1>Minimal example</h1>

+Let's start with the classic example:

+<div class="source">

+<pre><code>&lt;?php

+<span class="kw">require(</span><span class="str">'fpdf.php'</span><span class="kw">);

+

+</span>$pdf <span class="kw">= new </span>FPDF<span class="kw">();

+</span>$pdf<span class="kw">-&gt;</span>AddPage<span class="kw">();

+</span>$pdf<span class="kw">-&gt;</span>SetFont<span class="kw">(</span><span class="str">'Arial'</span><span class="kw">,</span><span class="str">'B'</span><span class="kw">,</span>16<span class="kw">);

+</span>$pdf<span class="kw">-&gt;</span>Cell<span class="kw">(</span>40<span class="kw">,</span>10<span class="kw">,</span><span class="str">'Hello World!'</span><span class="kw">);

+</span>$pdf<span class="kw">-&gt;</span>Output<span class="kw">();

+</span>?&gt;</code></pre>

+</div>

+<p class='demo'><a href='tuto1.php' target='_blank' class='demo'>[Demo]</a></p>

+After including the library file, we create an FPDF object.

+The <a href='../doc/fpdf.htm'>FPDF()</a> constructor is used here with the default values: pages are in A4 portrait and

+the unit of measure is millimeter. It could have been specified explicitly with:

+<div class="source">

+<pre><code>$pdf <span class="kw">= new </span>FPDF<span class="kw">(</span><span class="str">'P'</span><span class="kw">,</span><span class="str">'mm'</span><span class="kw">,</span><span class="str">'A4'</span><span class="kw">);

+</span></code></pre>

+</div>

+It's possible to use landscape (<code>L</code>), other page sizes (such as <code>Letter</code> and

+<code>Legal</code>) and units (<code>pt</code>, <code>cm</code>, <code>in</code>).

+<br>

+<br>

+There's no page at the moment, so we have to add one with <a href='../doc/addpage.htm'>AddPage()</a>. The origin

+is at the upper-left corner and the current position is by default set at 1 cm from the

+borders; the margins can be changed with <a href='../doc/setmargins.htm'>SetMargins()</a>.

+<br>

+<br>

+Before we can print text, it's mandatory to select a font with <a href='../doc/setfont.htm'>SetFont()</a>, otherwise the

+document would be invalid. We choose Arial bold 16:

+<div class="source">

+<pre><code>$pdf<span class="kw">-&gt;</span>SetFont<span class="kw">(</span><span class="str">'Arial'</span><span class="kw">,</span><span class="str">'B'</span><span class="kw">,</span>16<span class="kw">);

+</span></code></pre>

+</div>

+We could have specified italics with I, underlined with U or a regular font with an empty string

+(or any combination). Note that the font size is given in points, not millimeters (or another user

+unit); it's the only exception. The other standard fonts are Times, Courier, Symbol and ZapfDingbats.

+<br>

+<br>

+We can now print a cell with <a href='../doc/cell.htm'>Cell()</a>. A cell is a rectangular area, possibly framed,

+which contains a line of text. It is output at the current position. We specify its dimensions,

+its text (centered or aligned), if borders should be drawn, and where the current position

+moves after it (to the right, below or to the beginning of the next line). To add a frame, we would do this:

+<div class="source">

+<pre><code>$pdf<span class="kw">-&gt;</span>Cell<span class="kw">(</span>40<span class="kw">,</span>10<span class="kw">,</span><span class="str">'Hello World !'</span><span class="kw">,</span>1<span class="kw">);

+</span></code></pre>

+</div>

+To add a new cell next to it with centered text and go to the next line, we would do:

+<div class="source">

+<pre><code>$pdf<span class="kw">-&gt;</span>Cell<span class="kw">(</span>60<span class="kw">,</span>10<span class="kw">,</span><span class="str">'Powered by FPDF.'</span><span class="kw">,</span>0<span class="kw">,</span>1<span class="kw">,</span><span class="str">'C'</span><span class="kw">);

+</span></code></pre>

+</div>

+Remark: the line break can also be done with <a href='../doc/ln.htm'>Ln()</a>. This method additionnaly allows to specify

+the height of the break.

+<br>

+<br>

+Finally, the document is closed and sent to the browser with <a href='../doc/output.htm'>Output()</a>. We could have saved

+it to a file by passing the desired file name.

+<br>

+<br>

+<strong>Caution:</strong> in case when the PDF is sent to the browser, nothing else must be output by the

+script, neither before nor after (no HTML, not even a space or a carriage return). If you send something

+before, you will get the error message: "Some data has already been output, can't send PDF file". If you

+send something after, the document might not display.

+This example makes use of the <a href='../doc/header.htm'>Header()</a> and <a href='../doc/footer.htm'>Footer()</a> methods to process page headers and

+footers. They are called automatically. They already exist in the FPDF class but do nothing,

+therefore we have to extend the class and override them.

+<br>

+<br>

+The logo is printed with the <a href='../doc/image.htm'>Image()</a> method by specifying its upper-left corner and

+its width. The height is calculated automatically to respect the image proportions.

+<br>

+<br>

+To print the page number, a null value is passed as the cell width. It means that the cell

+should extend up to the right margin of the page; this is handy to center text. The current page

+number is returned by the <a href='../doc/pageno.htm'>PageNo()</a> method; as for the total number of pages, it's obtained

+via the special value <code>{nb}</code> which is substituted when the document is finished

+(provided you first called <a href='../doc/aliasnbpages.htm'>AliasNbPages()</a>).

+<br>

+Note the use of the <a href='../doc/sety.htm'>SetY()</a> method which allows to set position at an absolute location in

+the page, starting from the top or the bottom.

+<br>

+<br>

+Another interesting feature is used here: the automatic page breaking. As soon as a cell would

+cross a limit in the page (at 2 centimeters from the bottom by default), a break is issued

+and the font restored. Although the header and footer select their own font (Arial), the body

+continues with Times. This mechanism of automatic restoration also applies to colors and line

+width. The limit which triggers page breaks can be set with <a href='../doc/setautopagebreak.htm'>SetAutoPageBreak()</a>.

+The <a href='../doc/getstringwidth.htm'>GetStringWidth()</a> method allows to determine the length of a string in the current font,

+which is used here to calculate the position and the width of the frame surrounding the title.

+Then colors are set (via <a href='../doc/setdrawcolor.htm'>SetDrawColor()</a>, <a href='../doc/setfillcolor.htm'>SetFillColor()</a> and <a href='../doc/settextcolor.htm'>SetTextColor()</a>) and the

+thickness of the line is set to 1 mm (instead of 0.2 by default) with <a href='../doc/setlinewidth.htm'>SetLineWidth()</a>. Finally,

+we output the cell (the last parameter <code>true</code> indicates that the background must

+be filled).

+<br>

+<br>

+The method used to print the paragraphs is <a href='../doc/multicell.htm'>MultiCell()</a>. Each time a line reaches the

+right extremity of the cell or a carriage return character is met, a line break is issued

+and a new cell automatically created under the current one. Text is justified by default.

+<br>

+<br>

+Two document properties are defined: the title (<a href='../doc/settitle.htm'>SetTitle()</a>) and the author (<a href='../doc/setauthor.htm'>SetAuthor()</a>).

+There are several ways to view them in Adobe Reader. The first one is to open the file directly with

+the reader, go to the File menu and choose the Properties option. The second one, also available from

+the plug-in, is to right-click and select Document Properties. The third method is to type the Ctrl+D

+key combination.

+The key method used is <a href='../doc/acceptpagebreak.htm'>AcceptPageBreak()</a>. It allows to accept or not an automatic page

+break. By refusing it and altering the margin and current position, the desired column layout

+is achieved.

+<br>

+For the rest, not many changes; two properties have been added to the class to save the current

+column number and the position where columns begin, and the MultiCell() call specifies a

+6 centimeter width.

+A table being just a collection of cells, it's natural to build one from them. The first

+example is achieved in the most basic way possible: simple framed cells, all of the same size

+and left aligned. The result is rudimentary but very quick to obtain.

+<br>

+<br>

+The second table brings some improvements: each column has its own width, headings are centered,

+and numbers right aligned. Moreover, horizontal lines have been removed. This is done by means

+of the <code>border</code> parameter of the <a href='../doc/cell.htm'>Cell()</a> method, which specifies which sides of the

+cell must be drawn. Here we want the left (<code>L</code>) and right (<code>R</code>) ones. It remains

+the problem of the horizontal line to finish the table. There are two possibilities: either

+check for the last line in the loop, in which case we use <code>LRB</code> for the <code>border</code>

+parameter; or, as done here, add the line once the loop is over.

+<br>

+<br>

+The third table is similar to the second one but uses colors. Fill, text and line colors are

+simply specified. Alternate coloring for rows is obtained by using alternatively transparent

+and filled cells.

+The new method to print text is <a href='../doc/write.htm'>Write()</a>. It's very close to <a href='../doc/multicell.htm'>MultiCell()</a>; the differences are:

+<ul>

+<li>The end of line is at the right margin and the next line begins at the left one</li>

+<li>The current position moves at the end of the text</li>

+</ul>

+So it allows to write a chunk of text, alter the font style, then continue from the exact

+place we left it. On the other hand, you cannot justify it.

+<br>

+<br>

+The method is used on the first page to put a link pointing to the second one. The beginning of

+the sentence is written in regular style, then we switch to underline and finish it. The link

+is created with <a href='../doc/addlink.htm'>AddLink()</a>, which returns a link identifier. The identifier is

+passed as third parameter of Write(). Once the second page is created, we use <a href='../doc/setlink.htm'>SetLink()</a> to

+make the link point to the beginning of the current page.

+<br>

+<br>

+Then we put an image with an external link on it. An external link is just a URL. It's passed as

+last parameter of <a href='../doc/image.htm'>Image()</a>.

+<br>

+<br>

+Finally, the left margin is moved after the image with <a href='../doc/setleftmargin.htm'>SetLeftMargin()</a> and some text in

+HTML format is output. A very simple HTML parser is used for this, based on regular expressions.

+Recognized tags are &lt;b&gt;, &lt;i&gt;, &lt;u&gt;, &lt;a&gt; and &lt;br&gt;; the others are

+ignored. The parser also makes use of the Write() method. An external link is put the same way as

+an internal one (third parameter of Write()). Note that <a href='../doc/cell.htm'>Cell()</a> also allows to put links.

+<h1>Adding new fonts and encoding support</h1>

+This tutorial explains how to use TrueType, OpenType and Type1 fonts so that you are not limited to

+the standard fonts any more. The other benefit is that you can choose the font encoding, which allows

+you to use other languages than the Western ones (the standard fonts having too few available characters).

+<br>

+<br>

+Remark: for OpenType, only the format based on TrueType is supported (not the one based on Type1).

+<br>

+<br>

+There are two ways to use a new font: embedding it in the PDF or not. When a font is not

+embedded, it is searched in the system. The advantage is that the PDF file is lighter; on the other

+hand, if it's not available, a substitution font is used. So it's preferable to ensure that the

+needed font is installed on the client systems. If the file is to be viewed by a large audience,

+it's highly recommended to embed.

+<br>

+<br>

+Adding a new font requires two steps:

+<ul>

+<li>Generation of the font definition file</li>

+<li>Declaration of the font in the script</li>

+</ul>

+For Type1, you need the corresponding AFM file. It's usually provided with the font.

+

+<h2>Generation of the font definition file</h2>

+The first step consists in generating a PHP file containing all the information needed by FPDF;

+in addition, the font file is compressed. To do this, a helper script is provided in the makefont

+directory of the package: makefont.php. It contains the following function:

+<br>

+<br>

+<code>MakeFont(<b>string</b> fontfile, [, <b>string</b> enc [, <b>boolean</b> embed]])</code>

+<dl class="param" style="margin-bottom:2em">

+<dt><code>fontfile</code></dt>

+<dd>

+<p>Path to the .ttf, .otf or .pfb file.</p>

+</dd>

+<dt><code>enc</code></dt>

+<dd>

+<p>Name of the encoding to use. Default value: <code>cp1252</code>.</p>

+</dd>

+<dt><code>embed</code></dt>

+<dd>

+<p>Whether to embed the font or not. Default value: <code>true</code>.</p>

+</dd>

+</dl>

+The first parameter is the name of the font file. The extension must be either .ttf, .otf or .pfb and

+determines the font type. If your Type1 font is in ASCII format (.pfa), you can convert it to binary

+(.pfb) with the help of <a href="http://www.lcdf.org/~eddietwo/type/#t1utils" target="_blank">t1utils</a>.

+<br>

+<br>

+For Type1 fonts, the corresponding .afm file must be present in the same directory.

+<br>

+<br>

+The encoding defines the association between a code (from 0 to 255) and a character. The first 128 are

+always the same and correspond to ASCII; the following are variable. Encodings are stored in .map

+files. The available ones are:

+<ul>

+<li>cp1250 (Central Europe)</li>

+<li>cp1251 (Cyrillic)</li>

+<li>cp1252 (Western Europe)</li>

+<li>cp1253 (Greek)</li>

+<li>cp1254 (Turkish)</li>

+<li>cp1255 (Hebrew)</li>

+<li>cp1257 (Baltic)</li>

+<li>cp1258 (Vietnamese)</li>

+<li>cp874 (Thai)</li>

+<li>ISO-8859-1 (Western Europe)</li>

+<li>ISO-8859-2 (Central Europe)</li>

+<li>ISO-8859-4 (Baltic)</li>

+<li>ISO-8859-5 (Cyrillic)</li>

+<li>ISO-8859-7 (Greek)</li>

+<li>ISO-8859-9 (Turkish)</li>

+<li>ISO-8859-11 (Thai)</li>

+<li>ISO-8859-15 (Western Europe)</li>

+<li>ISO-8859-16 (Central Europe)</li>

+<li>KOI8-R (Russian)</li>

+<li>KOI8-U (Ukrainian)</li>

+</ul>

+Of course, the font must contain the characters corresponding to the chosen encoding.

+<br>

+<br>

+Remark: the standard fonts use cp1252.

+<br>

+<br>

+After you have called the function (create a new file for this and include makefont.php), a .php file

+is created, with the same name as the font file. You may rename it if you wish. If the case of embedding,

+the font file is compressed and gives a second file with .z as extension (except if the compression

+function is not available, it requires Zlib). You may rename it too, but in this case you have to change

+the variable <code>$file</code> in the .php file accordingly.

+<br>

+<br>

+Example:

+<div class="source">

+<pre><code>&lt;?php

+<span class="kw">require(</span><span class="str">'makefont/makefont.php'</span><span class="kw">);

+

+</span>MakeFont<span class="kw">(</span><span class="str">'c:\\Windows\\Fonts\\comic.ttf'</span><span class="kw">,</span><span class="str">'cp1252'</span><span class="kw">);

+</span>?&gt;</code></pre>

+</div>

+which gives the files comic.php and comic.z.

+<br>

+<br>

+Then copy the generated files to the font directory. If the font file could not be compressed, copy

+it directly instead of the .z version.

+<br>

+<br>

+Another way to call MakeFont() is through the command line:

+<br>

+<br>

+<kbd>php makefont\makefont.php c:\Windows\Fonts\comic.ttf cp1252</kbd>

+<br>

+<br>

+Finally, for TrueType and OpenType fonts, you can also generate the files

+<a href="http://www.fpdf.org/makefont/">online</a> instead of doing it manually.

+

+<h2>Declaration of the font in the script</h2>

+The second step is simple. You just need to call the <a href='../doc/addfont.htm'>AddFont()</a> method:

+<div class="source">

+<pre><code>$pdf<span class="kw">-&gt;</span>AddFont<span class="kw">(</span><span class="str">'Comic'</span><span class="kw">,</span><span class="str">''</span><span class="kw">,</span><span class="str">'comic.php'</span><span class="kw">);

+</span></code></pre>

+</div>

+And the font is now available (in regular and underlined styles), usable like the others. If we

+had worked with Comic Sans MS Bold (comicbd.ttf), we would have written:

+<div class="source">

+<pre><code>$pdf<span class="kw">-&gt;</span>AddFont<span class="kw">(</span><span class="str">'Comic'</span><span class="kw">,</span><span class="str">'B'</span><span class="kw">,</span><span class="str">'comicbd.php'</span><span class="kw">);

+</span></code></pre>

+</div>

+

+<h2>Example</h2>

+Let's now see a complete example. We will use the font <a href="http://www.abstractfonts.com/font/52" target="_blank">Calligrapher</a>.

+The first step is the generation of the font files:

+<div class="source">

+<pre><code>&lt;?php

+<span class="kw">require(</span><span class="str">'makefont/makefont.php'</span><span class="kw">);

+

+</span>MakeFont<span class="kw">(</span><span class="str">'calligra.ttf'</span><span class="kw">,</span><span class="str">'cp1252'</span><span class="kw">);

+</span>?&gt;</code></pre>

+</div>

+The script gives the following report:

+<br>

+<br>

+<b>Warning:</b> character Euro is missing<br>

+<b>Warning:</b> character zcaron is missing<br>

+Font file compressed: calligra.z<br>

+Font definition file generated: calligra.php<br>

+<br>

+The euro character is not present in the font (it's too old). Another character is missing too.

+<br>

+<br>

+Alternatively we could have used the command line:

+<br>

+<br>

+<kbd>php makefont\makefont.php calligra.ttf cp1252</kbd>

+<br>

+<br>

+or used the online generator.

+<br>

+<br>

+We can now copy the two generated files to the font directory and write the script:

+<div class="source">

+<pre><code>&lt;?php

+<span class="kw">require(</span><span class="str">'fpdf.php'</span><span class="kw">);

+

+</span>$pdf <span class="kw">= new </span>FPDF<span class="kw">();

+</span>$pdf<span class="kw">-&gt;</span>AddFont<span class="kw">(</span><span class="str">'Calligrapher'</span><span class="kw">,</span><span class="str">''</span><span class="kw">,</span><span class="str">'calligra.php'</span><span class="kw">);

+</span>$pdf<span class="kw">-&gt;</span>AddPage<span class="kw">();

+</span>$pdf<span class="kw">-&gt;</span>SetFont<span class="kw">(</span><span class="str">'Calligrapher'</span><span class="kw">,</span><span class="str">''</span><span class="kw">,</span>35<span class="kw">);

+</span>$pdf<span class="kw">-&gt;</span>Write<span class="kw">(</span>10<span class="kw">,</span><span class="str">'Enjoy new fonts with FPDF!'</span><span class="kw">);

+</span>$pdf<span class="kw">-&gt;</span>Output<span class="kw">();

+</span>?&gt;</code></pre>

+</div>

+<p class='demo'><a href='tuto7.php' target='_blank' class='demo'>[Demo]</a></p>

+

+<h2>About the euro symbol</h2>

+The euro character is not present in all encodings, and is not always placed at the same position:

+<table>

+<tr><th>Encoding</th><th>Position</th></tr>

+<tr class="alt0"><td>cp1250</td><td>128</td></tr>

+<tr class="alt1"><td>cp1251</td><td>136</td></tr>

+<tr class="alt0"><td>cp1252</td><td>128</td></tr>

+<tr class="alt1"><td>cp1253</td><td>128</td></tr>

+<tr class="alt0"><td>cp1254</td><td>128</td></tr>

+<tr class="alt1"><td>cp1255</td><td>128</td></tr>

+<tr class="alt0"><td>cp1257</td><td>128</td></tr>

+<tr class="alt1"><td>cp1258</td><td>128</td></tr>

+<tr class="alt0"><td>cp874</td><td>128</td></tr>

+<tr class="alt1"><td>ISO-8859-1</td><td>N/A</td></tr>

+<tr class="alt0"><td>ISO-8859-2</td><td>N/A</td></tr>

+<tr class="alt1"><td>ISO-8859-4</td><td>N/A</td></tr>

+<tr class="alt0"><td>ISO-8859-5</td><td>N/A</td></tr>

+<tr class="alt1"><td>ISO-8859-7</td><td>N/A</td></tr>

+<tr class="alt0"><td>ISO-8859-9</td><td>N/A</td></tr>

+<tr class="alt1"><td>ISO-8859-11</td><td>N/A</td></tr>

+<tr class="alt0"><td>ISO-8859-15</td><td>164</td></tr>

+<tr class="alt1"><td>ISO-8859-16</td><td>164</td></tr>

+<tr class="alt0"><td>KOI8-R</td><td>N/A</td></tr>

+<tr class="alt1"><td>KOI8-U</td><td>N/A</td></tr>

+</table>

+ISO-8859-1 is widespread but does not include the euro sign. If you need it, the simplest thing

+to do is to use cp1252 or ISO-8859-15 instead, which are nearly identical but contain the precious

+symbol.

+

+<h2>Reducing the size of TrueType fonts</h2>

+Font files are often quite voluminous; this is due to the fact that they contain the characters

+corresponding to many encodings. Zlib compression reduces them but they remain fairly big. A

+technique exists to reduce them further. It consists in converting the font to the Type1 format

+with <a href="http://ttf2pt1.sourceforge.net" target="_blank">ttf2pt1</a> (the Windows binary is

+available <a href="http://www.fpdf.org/fr/dl.php?id=22">here</a>) while specifying the encoding

+you are interested in; all other characters will be discarded.

+<br>

+For example, the arial.ttf font that ships with Windows Vista weights 748 KB (it contains 3381 characters).

+After compression it drops to 411. Let's convert it to Type1 by keeping only cp1250 characters:

+<br>

+<br>

+<kbd>ttf2pt1 -b -L cp1250.map c:\Windows\Fonts\arial.ttf arial</kbd>

+<br>

+<br>

+The .map files are located in the makefont directory of the package. The command produces

+arial.pfb and arial.afm. The arial.pfb file weights only 57 KB, and 53 after compression.

+<br>

+<br>

+It's possible to go even further. If you are interested only by a subset of the encoding (you

+probably don't need all 217 characters), you can open the .map file and remove the lines you are

+not interested in. This will reduce the file size accordingly.
