- TRIM -- a LaserJet Soft Font Management Utility [v1.1]
-
- Do you have some really huge soft font files from which you use only a
- few letters? Those three 80 point initials you use in your
- letterhead? And their soft font file is taking up 300k on your disk?
- And it takes 180 seconds of download time? And there's a cramp in
- your printer's memory?
-
- TRIM displays the characters of a soft font file and lets you type in
- just those you choose to keep in a trimmed down soft font file.
-
- Operation of the program should be intuitive. I won't belabor the
- obvious.
-
- Except that input for the "Type in the characters to keep. Press [F1]
- when finished" prompt may deserve some explanation. It's perfectly
- okay to supply a phrase with repeated letters -- TRIM isn't going to
- double any of those character descriptions.
-
- The input routine for that prompt may surprise you if you hit the
- <BackSpace>, <Escape>, or <Enter> keys. Those actions and others are
- represented by characters in the lower thirty-two ASCII set. They are
- shown on-screen as happy-faces, arrows, hearts, diamonds, musical
- notes, and other oddities.
-
- Since some fonts do include the lower thirty-two characters, it's
- necessary that they can be typed in at that prompt. That input
- routine allows such, and entry may be made directly from the keyboard
- if such a key exists, from a Ctrl-Key combination, or from Alt-KeyPad
- numeric entries.
-
- Consequently, there's no way to edit anything you type in there. A
- big fat cursor will remind you you're in an unusual input mode. Don't
- fret if you hit a <Backspace> or <Enter> by mistake and see their
- boxed-diamond and sixteenth-note characters appear on the list. If
- the original font doesn't have a character, TRIM isn't going to
- strangle trying to build it.
-
- Always keep in mind that the characters you see on screen may not be
- the actual characters printed by the soft font. That's true
- especially for the upper 128 characters in many sets and for the lower
- 32, if either group is present.
-
- You will be prompted for input and output file names as the program
- progresses. They may be identical if you have no wish to preserve the
- original font file.
-
- I've tried to adhere strictly to Hewlett Packard soft font
- specifications. If one of your soft fonts doesn't follow those rules,
- TRIM will simply give up and quit without trashing anything.
-
- HP specifications do allow huge characters to be defined in multiple
- blocks of about 32,000 bytes. I just can't find that anyone is using
- that capability, so I didn't build in support for it. TRIM will choke
- and quit if it does encounter such a continuation field.
