Depending on your PHP and GD versions this function is defined or not. With
|
|
PHP 4.0.6 through 4.1.x this function always exists if the GD module is
|
|
loaded, but calling it without GD2 being installed PHP will issue a fatal
|
|
error and exit. With PHP 4.2.x this behaviour is different in issuing a
|
|
warning instead of an error. Other versions only define this function, if
|
|
the correct GD version is installed.
