!FontEd/Bitmaps
This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.
Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

Editing bitmap fonts -------------------- Work done: ---------- 1) When creating a bitmap font, an encoding file may be specified. This file will be used to choose which characters from the outline font get put where in the bitmap font. The encoding name is simply typed into the dialogue box, either as a full path name or a leaf name to be sought under Font:Encodings. (hence you can normally just type Latin1). 2) When loading a bitmap font, the editor attempts to determine its encoding according to the same rule as the Font Manager, viz: determine the name of the immediate parent directory and look for an identically-named encoding file (in Font:Encodings.) Hence, when saving a bitmap font, you should put it in an appropriately-named subdirectory of the font directory. The metrics file will be sought in the main font directory as usual. 3) When editing a bitmap character you can now alter its size. To implement this sanely, a feature was sacrificed: the size of the bitmap is no longer automatically updated if you change the corresponding outline character. 4) A couple of old bugs have been noted, but not yet investigated.
