- Michael Mefford
- 1988 No. 15 (Utilities)
-
-
- Purpose: Permits modifying/creating EGA or VGA character fonts with
- keyboard or mouse and saving the new fonts as .COM files that can be loaded
- from the DOS prompt.
-
- Format: FONTEDIT
-
- Remarks: If no font filename and path are supplied as the FONTEDIT uses
- the currently-displayed font, beginning with the letter A. Pixels in the Edit
- window are toggled on or off with the spacebar or with left and right mouse
- buttons. The highlighted cursor may be moved within the Edit window by mouse
- or with the cursor Arrow keys, and it can be "dragged" to adjacent pixels by
- holding down a Shift key or mouse button. Editing changes are saved by
- pressing F4, and opportunity is provided to supply a missing filename.
- FONTEDIT will supply the requisite .COM extension automatically. Esc quits
- the program.
-
- Pressing F5 copies the original character template to Edit window.
- New characters to edit can be loaded by pressing the appropriate key on the
- keyboard, by pressing the PgUp and PgDn keys (which move in ASCII sequence),
- or by holding down the Alt key while typing the ASCII code on the numeric
- keypad, then releasing Alt. The Tab key toggles the cursor between the Edit
- window and the full Character Set window. Highlighted characters in the
- latter can be loaded for editing by pressing Enter or one of the mouse
- buttons.
-
- The F1, F2, and F3 keys affect all characters within the entire font.
- F1 (or the Del key) deletes a whole row of pixels, and is used to shorten the
- height of the character box. The default (and maximum) character box size is
- 8 pixels wide (this cannot be changed) by 14 pixels high (EGA) or 16 pixels
- high (VGA). A 43-line EGA font uses a character box of 8 by 8 pixels, for
- example. When using F1 (or Del) confirmation of the deletion is required.
- F2 inserts a blank row of pixels throughout the entire font (maximum height
- permitting), and F3 copies each character's current pixel map, as, for
- example, to thicken a serif.
-
- Modified or created fonts are loaded simply by entering their names at
- the DOS prompt. Normal operation is restored by entering any video mode
- command, for example MODE CO80, on a color system or MODE MONO in monochrome.
- Applications that reset the video mode on entry or when returning from DOS
- also restore the default ROM font and cannot be used successfully with
- FONTEDIT.
