imagepsencodefont
(PHP 4, PHP 5)
imagepsencodefont — Change the character encoding vector of a font
Description
$font_index
, string $encodingfile
)Loads a character encoding vector from a file and changes the fonts encoding vector to it. As a PostScript fonts default vector lacks most of the character positions above 127, you'll definitely want to change this if you use a language other than English.
If you find yourself using this function all the time, a much better way to define the encoding is to set ps.default_encoding in the configuration file to point to the right encoding file and all fonts you load will automatically have the right encoding.
Parameters
-
font_index -
A font resource, returned by imagepsloadfont().
-
encodingfile -
The exact format of this file is described in T1libs documentation. T1lib comes with two ready-to-use files, IsoLatin1.enc and IsoLatin2.enc.
Return Values
Returns TRUE on success or FALSE on failure.
Examples
Example #1 imagepsencodefont() example
<?php
// Load a .pfb font file
$font = imagepsloadfont('./px3l.pfb');
// Tell T1lib to use ISO Latin 1 encoding
imagepsencode($font, './IsoLatin1.enc');
// Do any operations with the font here
// Free the font from memory
imagepsfreefont($font);
?>
Notes
Note: This function is only available if PHP is compiled using --with-t1lib[=DIR] .

Because I have had problems with this function to find out that there is no result to store in a variable, a short example how to use:
$font = imagepsloadfont( "/home/www/font/Arial.pfb" );
imagepsencodefont( $font, "/home/www/font/IsoLatin1.enc" );
afterwards you can use the resource $font in each other ps function like imagepstext() or imagepsbbox().
The t1lib-5.0.0 source includes 5 different encoding files under Fonts/enc/. For my text with German umlauts, using IsoLatin1.enc did not work, but PSLatin1.enc did the trick.
