Hi,

Aside from -cmax and wt+, are there other tricks to increase contrast between text and shaded partial backgrounds? And is it possible to output black and white instead of grayscale or color? (I'm currently using a low value for -wt+ and it looks like black and while, but I'm not sure if it's just darker shades of gray and white.)
