TCPDF Fonts
|
|
|
|
TCPDF supports TrueTypeUnicode (UTF-8 Unicode), OpenTypeUnicode, TrueType, OpenType, Type1, CID-0 and Core (standard) fonts.
|
|
|
|
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 is not available, a substitution font is used. So it is 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 is recommended to embed.
|
|
|
|
The fonts that could be not embedded are only the standard core fonts and CID-0 fonts.
|
|
|
|
The PDF Core (standard) fonts are:
|
|
|
|
* courier : Courier
|
|
* courierb : Courier Bold
|
|
* courierbi : Courier Bold Italic
|
|
* courieri : Courier Italic
|
|
* helvetica : Helvetica
|
|
* helveticab : Helvetica Bold
|
|
* helveticabi : Helvetica Bold Italic
|
|
* helveticai : Helvetica Italic
|
|
* symbol : Symbol
|
|
* times : Times New Roman
|
|
* timesb : Times New Roman Bold
|
|
* timesbi : Times New Roman Bold Italic
|
|
* timesi : Times New Roman Italic
|
|
* zapfdingbats : Zapf Dingbats
|
|
|
|
Setting up a font for usage with TCPDF requires the following steps:
|
|
|
|
1. Convert all font filenames to lowercase and rename using the following schema:
|
|
* [basic-font-name-in-lowercase].ttf for regular font
|
|
* [basic-font-name-in-lowercase]b.ttf for bold variation
|
|
* [basic-font-name-in-lowercase]i.ttf for oblique variation
|
|
* [basic-font-name-in-lowercase]bi.ttf for bold oblique variation
|
|
|
|
2. Generate the font's metrics file.
|
|
* For Type1 font files this first step is not necessary because the AFM file is usually shipped with the font. In case you have only a metric file in PFM format, use the pfm2afm utility (fonts/utils/pfm2afm) to get the AFM file. If you own a Type1 font in ASCII format (.pfa), you can convert it to binary format with Type 1 utilities.
|
|
* For TrueTypeUnicode or TrueType font files, use the the provided ttf2ufm utility (fonts/utils/ttf2ufm):
|
|
|
|
$ ttf2ufm -a -F myfont.ttf
|
|
|
|
* For OpenTypeUnicode or OpenType font files, use the the provided ttf2ufm utility (fonts/utils/ttf2ufm):
|
|
|
|
$ ttf2ufm -a -F myfont.otf
|
|
|
|
3. Run makefont.php script.
|
|
* For TrueTypeUnicode:
|
|
|
|
$ php -q makefont.php myfont.ttf myfont.ufm
|
|
|
|
* For OpenTypeUnicode:
|
|
|
|
$ php -q makefont.php myfont.otf myfont.ufm
|
|
|
|
* For TrueType:
|
|
|
|
$ php -q makefont.php myfont.ttf myfont.afm
|
|
|
|
* For OpenType:
|
|
|
|
$ php -q makefont.php myfont.otf myfont.afm
|
|
|
|
* For Type1:
|
|
|
|
$ php -q makefont.php myfont.pfb myfont.afm
|
|
|
|
You may also specify additional parameters:
|
|
|
|
MakeFont(string $fontfile, string $fmfile [, boolean $embedded [, $enc="cp1252" [, $patch=array()]]])
|
|
|
|
* $fontfile : Path to the .ttf or .pfb file.
|
|
* $fmfile : Path to the .afm file for Type1 and TrueType or .ufm for TrueTypeUnicode.
|
|
* $embedded : Set to false to not embed the font, true otherwise (default).
|
|
* $enc : Name of the encoding table to use. Default value: cp1252. Omit this parameter for TrueType Unicode, OpenType Unicode and symbolic fonts like Symbol or ZapfDingBats. The encoding defines the association between a code (from 0 to 255) and a character. The first 128 are fixed and correspond to ASCII. The encodings are stored in .map files. Those available are:
|
|
o cp1250 (Central Europe)
|
|
o cp1251 (Cyrillic)
|
|
o cp1252 (Western Europe)
|
|
o cp1253 (Greek)
|
|
o cp1254 (Turkish)
|
|
o cp1255 (Hebrew)
|
|
o cp1257 (Baltic)
|
|
o cp1258 (Vietnamese)
|
|
o cp874 (Thai)
|
|
o iso-8859-1 (Western Europe)
|
|
o iso-8859-2 (Central Europe)
|
|
o iso-8859-4 (Baltic)
|
|
o iso-8859-5 (Cyrillic)
|
|
o iso-8859-7 (Greek)
|
|
o iso-8859-9 (Turkish)
|
|
o iso-8859-11 (Thai)
|
|
o iso-8859-15 (Western Europe)
|
|
o iso-8859-16 (Central Europe)
|
|
o koi8-r (Russian)
|
|
o koi8-u (Ukrainian)
|
|
Of course, the font must contain the characters corresponding to the chosen encoding. The encodings which begin with cp are those used by Windows; Linux systems usually use ISO.
|
|
* $patch : Optional modification of the encoding. Empty by default. This parameter gives the possibility to alter the encoding. Sometimes you may want to add some characters. For instance, ISO-8859-1 does not contain the euro symbol. To add it at position 164, pass array(164=>'Euro').
|
|
|
|
4. Edit and copy resulting files by case:
|
|
* For embedded fonts: copy the resulting .php, .z and .ctg.z (if available) files to the TCPDF fonts directory.
|
|
* For not-embedding the font, edit the .php file and comment the $file entry.
|
|
* For CID-0 fonts (not embeddeed) you have to edit the .php file:
|
|
o change the font type to: $type='cidfont0';
|
|
o set the default font width by adding the line: $dw=1000;
|
|
o remove the $enc, $file and $ctg variables definitions
|
|
o add one of the following blocks of text at the end of the file (depends by the language you are using - see the arialunicid0.php file for a working example):
|
|
+ // Chinese Simplified
|
|
$enc='UniCNS-UTF16-H';
|
|
$cidinfo=array('Registry'=>'Adobe', 'Ordering'=>'CNS1','Supplement'=>0);
|
|
include(dirname(__FILE__).'/uni2cid_ac16.php');
|
|
|
|
+ // Chinese Traditional
|
|
$enc='UniGB-UTF16-H';
|
|
$cidinfo=array('Registry'=>'Adobe', 'Ordering'=>'GB1','Supplement'=>2);
|
|
include(dirname(__FILE__).'/uni2cid_ag15.php');
|
|
|
|
+ // Korean
|
|
$enc='UniKS-UTF16-H';
|
|
$cidinfo=array('Registry'=>'Adobe', 'Ordering'=>'Korea1','Supplement'=>0);
|
|
include(dirname(__FILE__).'/uni2cid_ak12.php');
|
|
|
|
+ // Japanese
|
|
$enc='UniJIS-UTF16-H';
|
|
$cidinfo=array('Registry'=>'Adobe', 'Ordering'=>'Japan1','Supplement'=>5);
|
|
include(dirname(__FILE__).'/uni2cid_aj16.php');
|
|
|
|
o copy the .php file to the TCPDF fonts directory.
|
|
5. Rename php font files variations using the following schema:
|
|
* [basic-font-name-in-lowercase].php for regular font
|
|
* [basic-font-name-in-lowercase]b.php for bold variation
|
|
* [basic-font-name-in-lowercase]i.php for oblique variation
|
|
* [basic-font-name-in-lowercase]bi.php for bold oblique variation
|
