PSF Tools

The PSF Tools are an attempt to do something similar to NetPBM, for simple fixed-width bitmap fonts.

The current release can convert the following formats to PSF:

and PSF to the following formats:

New in this release (1.1.x):

[1.1.3] New utility (psfdiff) to compare two PSF files as a visual image.
[1.1.3] New utilities (psfxsaa, vfontxsaa) to upscale fonts using the SAA5050 smoothing algorithm.
[1.1.3] Bug fix for crashes working with Windows 1 .FNT files
[1.1.2] Bug fixes for loading custom code pages.
[1.1.2] Direct conversion of vfont files to BDF, to/from Windows FNT.
[1.1.1] Support for conversion to and from vfont / vfont2.
[1.1.1] Support added for (internal and external) code page mappings with more than 256 characters. The format of the .CP2 files used to hold these mappings has been changed accordingly.
[1.1.1] Codepage names are now matched case-insensitively.
[1.1.1] New codepages: LS3 (LocoScript 3), QX10 (Epson QX-10) and PRINTIT (MML Systems Printit, a subset of QX10)
[1.1.0] raw2psf: Bugfix: --codepage was not setting the Unicode mapping on the last character in the font.
[1.1.0] ams2psf, psf2ams: Now support SCRCHAR.JOY, the LocoScript screen font file
[1.1.0] psf2ams: If passed an 8x16 font, the self-loading COM file now loads it at full height on the PCW16 (and scales it down on other computers).
[1.1.0] psf2ams: A short .PSF font converted to a .COM file will now only redefine those characters defined by the .PSF font.
[1.1.0] psf2xbm: Added an --across option allowing the width of the output bitmap to be changed (height is adjusted to match).

GRABFONT extracts the current font from an EGA or higher graphics card;
while RIPFONT allows patient people with good eyesight to do the same with a CGA or Hercules card.

My GEM programs include SYSFONT, a font editor for GEM which supports loading and saving PSF1 fonts.

I've written a PSF loader for Amstrad CP/M (LDPSFSEA.COM, about two-thirds of the way down the page). Source is included so it may be possible to adapt it for other CP/M systems.
