Point well taken regarding jpeg. Nonetheless, my text is still looking pretty funky. Any other suggestions
I've repeated your experiment, and yes, it doesn't look so good. I think the issue is that that is a very skinny font, and rendering it with anti-aliasing at 72dpi (which it appears is the default -- I can't find anything in the PIL docs about setting dpi, or what unit the "size" of a font is given in). Some systems use tricks to line up the lines of a font with the pixels to make this sort of thing look better (MS ClearType). Here's a bit of discussion about that:
http://www.antigrain.com/research/font_rasterization/index.htmlIt looks like PIL isn't trying to do anything special in that regard. You might try the agg renderer -- I don't know if it's different, but it might be.
I'd use a thicker font, it looks much better -- see enclosure.

print "size of X is:", font.getsize("X")
