I'm implementing a pdf generator in PHP I have problem with word spacing, the option doesn't work or i'm not using word spacing parameter properly. I need this option to render text justified. The character spacing parameter works properly. This is how I'm rendering text:

Word spacing parameter is bold. What i'm doing wrong?
