[REBOL] Re: Justifying text

It looks strange to me, since PDF is considered to be a subset of PostScript feature-wise, and PDF allows you to just set the char- and word-spacing. For example, this is a justified line created by PDF Maker: 0.239095357142857 Tw 0.03347335 Tc [(Suppor) -40 (t f) 30 (or custom f) 30 (onts w) 10 (ould definitely require w) 10 (or) -15 (k to be added;) 50 ( justification and r) -15 (ight alignment)] TJ Tw sets the word spacing, Tc the character spacing. The numbers in the text are for kerning. Regards, Gabriele. -- Gabriele Santilli <[g--santilli--tiscalinet--it]> -- REBOL Programmer Amigan -- AGI L'Aquila -- REB: http://web.tiscali.it/rebol/index.r
