bdf2ttf converts font files in BDF which is bitmap font to a TrueType Font (TTF) format file. bdf2ttf uses TTF's embedded bitmap font feature for conversion. So conversion time is very short, and result TTF will be very small. But embedded bitmap font is size depended, when you it use with specifing different size, you would get dusty glyphs rendered.
