(So if I specify --text-width=480 and --margin=10, the result > will always be 500 pixels/points wide). That's a bit trickier than you'd imagine. I've done this before for a client. The only way I can get really scalable text is to get the glyphs set for a nominal size, convert to outlines using cairo, and scale the outline. That said, when I add my own TT table handling, I may be able to just let go of FreeType and then everything will be truly scalable (but not hinted). > 2.

I did this to pango-view, and will do with hb-view. > Please bear in mind that it's the first time in my life that I touched > some C or C++ code EVER.

I'm still undecided whether I want this in a separate tool (that wouldn't link to cairo) or in hb-view. Perhaps I add it as you suggest (with format="xml" and format="js" or format="json" perhaps), and see how it goes. > I think it should be no more than 1-2 hours, and you'd make me really > happy.

I need that for hb's test suite too. behdad > Many thanks, > Adam _______________________________________________ HarfBuzz mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/harfbuzz
