- But then we're talking about printing a font 7 inches tall at 360 dpi!
- You would fit one or two letters on a standard page! If a situation like
- that ever arises, one should assume the user is intelligent enough to print
- at maybe 180 or even 72 dpi (don't know if that's possible with the
- StyleWriter, I use Harmonie...)
-
- Regarding memory usage: since Pointless 2.0 renders only those
- characters that are actually printed, the problem is alleviated somewhat.
- Assume a roughly square character bounds rectangle and some headline font
- at 1000 points. This translates to roughly 200 points (2.75 inches) on a
- 360-dpi printer (why did you use 4.5 instead of 5 in your calculations
- above?), more than adequate for most purposes. If 12 different characters
- are used in the headline, a little over 1.4 megs will be eaten up. This is
- certainly within the capabilities of a 4.25-meg GS. It also makes those
- 8-megabyte cards look *very* attractive. ;-)

- But we have been using extreme examples. Especially with better memory
- management in Pointless 2.0, fonts larger than 255 points are technically
- feasible.
