|
* Purpose : Figlet font class
|
|
*
|
|
* Comments : phpFiglet is a php class to somewhat recreate the
|
|
* functionality provided by the original figlet program
|
|
* (http://www.figlet.org/). It does not (yet) support the
|
|
* more advanced features like kerning or smushing. It can
|
|
* use the same (flf2a) fonts as the original figlet program
|
|
* (see their website for more fonts).
|
|
*
|
|
* Usage : $phpFiglet = new phpFiglet();
|
|
*
|
|
* if ($phpFiglet->loadFont("fonts/standard.flf")) {
|
|
* $phpFiglet->display("Hello World");
|
|
* } else {
|
|
* trigger_error("Could not load font file");
|
|
* }
|
|
*
