Anybody know how to draw text with an already bold font, more boldly?

Thanks,

Someone suggested thick outline strokes same color as text.
Someone else suggested dithering.
Shrug. Haven't experimented.

OK, I won't.  I did try changing the stroke but I'm not sure that works 
when drawing characters but maybe I don't know what I'm doing.

Thanks for looking.

Sorry for pointing to a seriously broken page
(I hope not intentionally broken)

I did just try dithering a text in Swing - butt ugly.

Anyway from that page

Thanks to all of you: that looks very much as if you've answered a
