- Adobe hints are used in rasterization of an outline. They try to
- ensure that strokes have the same width, and so on. But they can't fix
- an outline designed for 72 point to work well at 6 point. When you
- reduce sizes, you need to make open spaces larger, thins relatively
- thicker, and so on.
-
- However, Bitstream's hints are much more intelligent, and in practice
- alter the way they rasterize an outline at small point sizes to avoid
- some of the problems with using an outline designed at a different size.
- That's why Bitstream's fontware produces better looking output than
- Adobe or Compugraphic.
