SWFText::setSpacing — Sets the current font spacing
$spacing) : void
This function is EXPERIMENTAL. The behaviour of this function, its name, and surrounding documentation may change without notice in a future release of PHP. This function should be used at your own risk.
swftext::setspacing() sets the current font spacing to
spacing. Default is 1.0.
0 is all of the letters written at the same point. This doesn't really work
that well because it inflates the advance across the letter, doesn't add
the same amount of spacing between the letters. I should try and explain
that better, prolly. Or just fix the damn thing to do constant spacing.
This was really just a way to figure out how letter advances work,
anyway.. So nyah.
No value is returned.
