CharDef is a program to (re)define the systemfont or to install a systemfont from disc.
How do you use the program?
---------------------------
CharDef is a multitasking RISC OS-application and is written according to the Acorn guidelines (that is: I hope it is). Doubleclick on the CharDef- icon to install the program on the iconbar as a task. Click on the CharDef-icon on the iconbar to get the main CharDef-window. Click on a character in this window to get an edit-window. Click on a character-pixel to make it black or white. With the menu-option Alter you can rotate or shift your character. Store lets you temporarily store a character-definition. Install installs the changed character as a systemfont-character.
When you want to save your changed characterset you can choose the menu-option Save. Enter a sensible filename and drag the file-icon to the desired directory.
A font can be loaded by dragging a systemfont file-icon to the CharDef-icon on the iconbar or the main window of the program. A systemfont must
have filetype BBCfont (&FF7). This will be the case when you haved saved your characterset with this program.
Loading a systemfont into the program is equivalent to installing a systemfont by doubleclicking on a systemfont-file. So you can also load a font by doubleclicking on a font-file.
Why do you need a systemfont editor?
------------------------------------
The systemfont is the most easy to use character-font of the Archimedes-computer. It is fast and always very readable. But it has one shortcoming: there is by definition only ONE systemfont. This program changes that. Now you can alter the pound character into a Dutch guilder character if you really want that (just an example!).
A useful application is to define a mathematical characterset which can be used with First Word Plus. If you download the same characters to your printer you can edit and print a mathematical paper! In the next version of CharDef you can edit dot matrix download characters and install them on your printer.
