- Font Editor v3.0

-
- Introduction
- ~~~~~~~~~~~~
- This is a font editor to edit the VGA font (yep, a REALLY useful piece
- of software !). Once a font has been created, a TSR program or a Device
- Driver can be created to allow the font to be loaded and remain resident
- for other programs. Font Editor is definitely not crippled in anyway,
- and you only have to put up with a shareware window poping up when its
- first loaded. The Device driver and TSR that can be created only require
- an mere 4K.
-
- This program is shareware and you are encouraged to pass it along to
- others. If you find the font editor useful (you never know, it could
- happen) then please send an registration fee of a mere $20 (N.Z.) and
- you will get a copy of the registered version and it will allow me to
- have a hot meal. Your comments and suggestions are most welcome.
-
- As well as the latest version the registered version includes the source
- code for the TSR (A86 Assembler source), the source code to the device
- driver (TASM Assembler) and source example code for using your designed
- fonts in Pascal, C, and Assembler.

-
- Using the Font Editor
- ~~~~~~~~~~~~~~~~~~~~~
-
- The file name of the font to edit can be specified on the command line,
- otherwise the system font is used. To create a new font file specify the
- file name and include a /S on the command line to get the system VGA
- font. Once the program is loaded there are three main windows: the
- current character being edited, the available ASCII characters, and the
- details about the current character. To move between the editing window
- and the ASCII chart use [TAB]. To indicate which window is active the
- border will change to a double line in the active window. The arrow keys
- will move the highlite marker about. To change a pixel (while in the
- character window) press [SPACE], and to select a new character (while in
- the ASCII chart screen) press [ENTER].
-
- While moving about the ASCII chart window each characters ASCII value is
- displayed in decimal, hex and binary.
-
- Edit Keys
- ~~~~~~~~~
-
- F1 - Display help screen
-
- F2 - Save font file to disk (fnt), this over writes the
- existing file, which is displayed at the bottom of the
- screen. No backup is made.
-
- F3 - Erase current character (just blank it out).
-
- Shift+F3 - Fill current character (making it a solid block).
-
- Ctrl+F3 - Toggle current character, this will switch the pixels
- around, making the character go into a reverse mode.
-
- F4 - Create a device driver for the current font, with the
- same name as the current font. The device driver has
- the extension SYS, to be loaded from the CONFIG.SYS
- file with the DEVICE= command.
-
- F5 - As above but with the extension COM. This TSR can be
- loaded from DOS to switch to the new font.
-
- Ctrl+F5 - Create TSR without initialising font, this does the
- same as the above option, but the font isn't turned on
- straight away. Once the VGA mode is reset the font
- will be activated.
-
- F6 - This creates a file with the extension PAS, which is
- which is suitable for importing into pascal programs.
-
- F7 - As above, but the format is for C programs, with the
- extension being C.
-
- F8 - As [F6] but the extension will be ASM, and is suitable
- for most assemblers.
-
- F9 - This replaces the current character, whether in the
- ASCII window or editing window with the system font.
-
- Shift+F9 - Same as above but it gets all the system characters.
-
- Ctrl+F9 - Same as [F9] but uses the alternative font. If no
- alternative font has been loaded then this can't be
- done.
-
- F10 - This displays a window of .fnt files. The window
- display can be toggled by pressing [SPACE]. Select the
- file you wish to load with [ENTER].
-
- Ctrl+F10 - This loads an alternative font file, but the font
- won't be displayed, and can be accessed with the
- [Ctrl-F9] option.
-
- C - Copy character to buffer, this can only be done while
- in the editing window.
-
- P - Paste character from buffer, if no character has been
- previously copied then the pasted character will be
- blank or garbage.
-
- H - Flip the current character horizontally.
-
- V - Flip the current character vertically.
-
- Using Shift+Arrow keys while in the edit window will scroll the current
- character about the box in the various directions.
-
- If the program is started with no parameters the system font will be
- used and its file name will be default.fnt.
-
- A small screen flicker will occur when changing a fonts pixel - this is
- because of the interrupt updating the memory, depending on your video
- card the degree of flicker might vary.
-

-
- Other Stuff
- ~~~~~~~~~~~
-
- The file format is simply 16 bytes for each character, which is made up
- from the bit pattern in binary. Each font file should always be 4096
- bytes in size, and each character has 16 bytes.
-
- The headers that can be created are for including into your own programs
- if you want to customise the font, the assembler code might need
- changing to meet your requirements. The TSR and device driver will
- prevent the font reverting back to the original VGA card font by
- installing itself on interrupt 10, although one or two programs will
- still get rid of it, I have only found two :- 'Carbon Copy', and 'More
- Fonts', however I am sure there others. Some programs will lose the font
- when switching to and from different graphics/text modes, but it usually
- gets restored when the program is exited. The TSR & Device Driver only
- requires a modest bit of memory (about 4k), and can be loaded high with
- no problems, I haven`t had it cause any conflicts with anything (yet !).
- Thanks to Gary Anderson for helping me with the initial TSR and the
- system font.
