(PHP 3 = 3.0.9, PHP 4 )
Use this function if you need make further modifications
to the font, for example extending/condensing, slanting it or
changing it's character encoding vector, but need to keep the
original along as well. Note that the font you want to copy
must be one obtained using
imagepsloadfont(), not a font that is itself a copied
one. You can although make modifications to it before
copying.
If you use this function, you must free the fonts obtained this
way yourself and in reverse order. Otherwise your script
will
hang.
In the case everything went right, a valid font index
will be returned and can be used for further purposes.
Otherwise the function returns
FALSE and prints a message describing what went
wrong.
