dompdf : New Font Installation


Steps to follow :

1)      Install DOMPDF 0.6.0 or greater (Recommended : 0.6.0_beta3 )
2)      Enable the MBString PHP extension.
3)      Load a font supporting your characters into DOMPDF.
4)      Configure DOMPDF for Unicode support.
5)      Create a compatible HTML document.

First two steps has already been covered in previous post. Check here : dompdf : HTML to PDF Converter in PHP

3) We are going to use web-based font prep tool to install font.

This option is provided for users who are unable to set up the ttf2ufm application. This tool produces an archive containing the necessary font metrics file(s), the original font file(s), and a sample dompdf_font_family_cache that you should be able to use with your DOMPDF installation. AfterSimply provide a font name and the TTF file(s) (at a minimum you must provide a font file for the base variant); select the font parser (the PHP-based parser is recommended for larger fonts); and choose the version of DOMPDF you are using. After you submit the form the tool should return an archive containing the necessary files. Extract the contents of this archive into your DOMPDF font directory (typically dompdf/lib/fonts). If you have not previously installed other fonts you can rename dompdf_font_family_cache.sample to dompdf_font_family_cache. If you have already installed other fonts you will need to manually add the entries for your font to the dompdf_font_family_cache. 

Follow these steps.

a)     Download ttf file from internet. For example I just downloaded ‘Asman’ font ttf file from http://www.urbanfonts.com/fonts.php?fontauthor=2761

b)     Find the web-based font prep tool at http://eclecticgeek.com/dompdf/load_font.php.

c)     Provide Font Name  : Asman and TTF file we had downloaded in step (a).

d)     After submit you will get a file named ‘dompdf_fonts.zip’. Save it. Extract it and you 
        will find three files. 

 i) ASMAN.ttf  ii) ASMAN.ufm  iii) dompdf_font_family_cache.sample 

Copy ASMAN.ttf and ASMAN.ufm files in \dompdf\lib\fonts\ folder.

e)     Find the code of related font from downloaded dompdf_font_family_cache.sample file and add it at the end of  ..\dompdf\lib\fonts\dompdf_font_family_cache.sample file. For example:

<?php return array (
  'sans-serif' =>
  array (
    'normal' => DOMPDF_FONT_DIR . 'Helvetica',
    'bold' => DOMPDF_FONT_DIR . 'Helvetica-Bold',
    'italic' => DOMPDF_FONT_DIR . 'Helvetica-Oblique',
    'bold_italic' => DOMPDF_FONT_DIR . 'Helvetica-BoldOblique',
  ),
  'times' =>
  array (
    'normal' => DOMPDF_FONT_DIR . 'Times-Roman',
    'bold' => DOMPDF_FONT_DIR . 'Times-Bold',
    'italic' => DOMPDF_FONT_DIR . 'Times-Italic',
    'bold_italic' => DOMPDF_FONT_DIR . 'Times-BoldItalic',
  ),
……………………………………………………………………
……………………………………………………………………
……………………………………………………………………
……………………………………………………………………
  'asman' =>
  array (
    'normal' => DOMPDF_FONT_DIR . 'ASMAN',
    'bold' => DOMPDF_FONT_DIR . 'ASMAN',
    'italic' => DOMPDF_FONT_DIR . 'ASMAN',
    'bold_italic' => DOMPDF_FONT_DIR . 'ASMAN',
  ),
) ?>
  
4) Configure DOMPDF for Unicode support 

For DOMPDF to handle your characters correctly you must enable Unicode support in your configuration. Edit dompdf_config.inc.php or dompdf_config.custom.inc.php so that DOMPDF_UNICODE_ENABLED is true. Without enabling this setting your text will be re-encoded to Windows ANSI when inserted into the PDF and any characters that fall outside this encoding will be converted to question marks.

5) Create a compatible HTML document

For DOMPDF to correctly parse your document you must let it know what encoding is used. To do this place a meta tag in the head of your document that specifies the encoding. We recommend encoding documents using UTF-8 for greatest compatibility. However, you should be able to use other encodings so long as the computer where DOMPDF is installed supports the specified encoding. 

Example :

test.php  

<?php

require_once("../dompdf_config.inc.php");
$html = '<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Table</title>
<style>
body{
                font-family:Arial, Helvetica, sans-serif;
                font-size:12px;
}

table tr th{
    text-align:left;
    vertical-align:top;
}

.italic_text{
    font-family: asman,
    font-style:italic;
    font-size:12px;
    line-height:14px !important;
}

div{

            text-align:center;
}

</style>

</head>
<body>
            <div><h1>Test Document</h1></div>

            <table cellspacing="0" cellpadding="0" border="0">
            <tr>
                        <td class="italic_text"><h3>DirtyhandsPHP</h3></td>
            </tr>
            </table>
</body>
</html>';


if ( get_magic_quotes_gpc() )
               $str = stripslashes($str);

$dompdf = new DOMPDF();
$dompdf->load_html($html);
$dompdf->set_paper('letter', 'landscape');
$dompdf->render();

//Set Attachment attribute as True to show download file dialog box
$dompdf->stream("dompdf_out.pdf", array("Attachment" => false));

//For Attachment to sent in email
//$output = $dompdf->output();

exit(0);
 
?>

Output : dompdf_out.pdf file.

dompdf : HTML to PDF Converter in PHP

Recently, there was an requirement in a project to convert HTML to PDF at run time. While I was going through google, found two very good libraries named 'wkhtmltopdf' and 'dompdf'. dompdf was fulfilling my criteria so i went with that only. Just sharing that with you.

dompdf is an HTML to PDF converter library. At its heart, dompdf is (mostly) CSS2.1 compliant HTML layout and rendering engine written in PHP. It is a style-driven renderer: it will download and read external stylesheets, inline style tags, and the style attributes of individual HTML elements. It also supports most presentational HTML attributes.

Download dompdf library from here.

Recommended Version : 0.6.0_beta3

Requirements : 

1)       PHP 5.0+ (5.3 recommended)
2)      MBString extension - for better Unicode support.
3)      DOM extension (bundled with PHP 5) –“The DOM extension allows you to operate on XML documents through the DOM API with PHP 5.” 

Pros: 

1)      Easy to Use.
2)      Well Documented.
3)      Better CSS support except few things like ‘css : float’ property.

Cons(Known Issues) :  

1)       Not particularly tolerant to poorly-formed HTML input (using Tidy first may help).
2)       Large files or large tables can take a while to render.
3)       CSS float is not supported.

How To Use : 

Following is a simple example to show use of dompdf library.

test.php


<?php

require_once("../dompdf_config.inc.php");
$html = '<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Table</title>
<style>
body{
                font-family:Arial, Helvetica, sans-serif;
                font-size:12px;
}

table tr th{
    text-align:left;
    vertical-align:top;
}

.italic_text{
    font-style:italic;
    font-size:12px;
    line-height:14px !important;
}

div{
            text-align:center;
}

</style>
</head>
<body>
            <div><h1>Test Document</h1></div>

            <table cellspacing="0" cellpadding="0" border="0">
            <tr>
                        <td class="italic_text"><h3>DirtyhandsPHP</h3></td>
            </tr>
            </table>
</body>
</html>';


if ( get_magic_quotes_gpc() )
               $str = stripslashes($str);

$dompdf = new DOMPDF();
$dompdf->load_html($html);
$dompdf->set_paper('letter', 'landscape');
$dompdf->render();

//Set Attachment attribute as True to show download file dialog box
$dompdf->stream("dompdf_out.pdf", array("Attachment" => false));

//For Attachment to sent in email
//$output = $dompdf->output();

exit(0);

?>
