-This fontpack contains pixel-accurate remakes of various type styles
+This fontpack contains remakes of various type styles
from text-mode era PCs — in modern Unicode-compatible TrueType form
(plus straight bitmap versions). The main focus is on hardware
character sets: the kind that's located in a ROM and shown by default
when working in text (or graphics) mode.
-[These fonts are not corrected for the different pixel ratios used by
-the eponymous historic hardware; you need to manually do this with e.g.
-`xterm -fa "ATI 8x16:matrix=1 0 0 1.35"`]
+[ Classic hardware text mode stretches the fonts to fit the screen!
+To recreate the same visuals of that, a stretch factor must be
+applied. For details, see ratio.txt inside the package. ]

In classic IBM PC text mode, the graphics card stretches the font
such that it fills the screen.
A 9x16 font over 80x25 columns is displayed as a 720x400 image.
Assuming a 4:3 monitor as typically was present in the days, this
leads to a pixel aspect ratio of 20:27.
Font size Image size aspect decimal inverse
------------------------------------------------------------
8x8 640x200 5:12 0.42 2.40
8x14 640x350 35:48 0.73 1.37
8x16 640x400 5:6 0.83 1.20
9x16 720x400 20:27 0.74 1.35
To faithfully recreate the same visual look as such a monitor would
show, this aspect ratio needs to be applied when making use of the
font.
For cool-retro-term, there is a "Font Width" slider in the settings;
set it to 74%, 83%, or whatever is necessary. (Notice the pattern of
the "decimal" column of our table.)
For xterm, a fontconfig matrix can be specified like so:
xterm -fa "Px437 ATI 9x16:matrix=0.74 0 0 1"
xterm -fa "Px437 ATI 9x16:matrix=1 0 0 1.35"
One can either horizontally compress the glyphs, or vertically
stretch them to get to the result. The compress/stretch action
influences how many characters will be visible in a fullscreen
setting, so the basic font size may need to be adjusted.
xterm -fa "Px437 ATI 9x16:size=32:matrix=0.74 0 0 1"
xterm -fa "Px437 ATI 9x16:size=24:matrix=1 0 0 1.35"
produce an equivalent result.
Extra caveat: When using a matrix, you should also specify the -fd
parameter *and* specify the same matrix inside the -fd font
specification. Otherwise, CJK characters will be rendered in a
different size than the main characters. For a stretching matrix like
1/1.35, not specifying -fd and, as a result, having smaller CJK chars
is not as bad a problem as having bigger truncated CJK chars with a
compressing matrix like 0.74/1.
