Although the Amiga comes with a number of interesting and useful fonts, there
are no fonts that are particulary well-suited for low-resolution screens.
For example, if you create a new CLI on a LORES screen, the standard Topaz
font makes it possible to have no more than about 37 characters per line,
which makes the CLI virually useless.
This directory contains fonts that are smaller than the usual Topaz font
in an attempt to fill this gap in the Amiga font situation. There are two
classes of fonts, one set for HIRES screens, and one for LORES screens. The
name of each font indicates the screen resolution and the width of the
characters in the font. For example, HiRes-6 is a set of fonts designed for
HiRes screens where each character is 6 pixels wide (including the inter-
letter spacing). The point size of the font indicates how tall it is. For
example, Hires-6 comes in point sizes 6, 7 and 8, which are 6, 7, and 8
pixels tall, respectively. (All the fonts come in these three sizes, except
for HiRes-7).
These fonts include all the printable characters in the extended (255
character) ASCII table used by the Amiga, including the characters with
diacritical marks, etc. Thus you can use them in place of the Topaz font
without problems. The smaller versions, particularly the 6 point sizes,
leave something to be desired as far as the diactirical marks go, but the
standard characters are reasonably well-formed throughout all the sizes.
You can use the SetFont utility to install a font as the current font for a
particular CLI window, or for an entire screen. See the documentation for
SetFont for a complete description of how to do this.
The main difference between the LoRes and HiRes versions are that the HiRes
fonts have an extra blank pixel separating the letters (to help make it
easier to distinguish one letter from another), and some characters (like the
period and colon) have been widened slightly to make them easier to see in
the HIRES screen resolution. For example, the LoRes-4 and HiRes-5 fonts both
use essentially the same character images, but the HiRes-5 font has an extra
blank pixel on the right. An exception to this rule is the HiRes-5a font,
which does not have the extra pixel; it uses the full 4 pixel width for its
characters. Thus they are better formed, but they tend to run into each
other visually. Use your own preference when choosing an appropriate font
for your work.
The standard CLI window on a HIRES, non-interlaced Workbench screen provides
23 lines of up to 77 characters each. A LORES screen gives 23 lines of only
37 chartacters each! The HiRes and LoRes fonts provided here can increase
both the number of characters per line, and the number of lines that you can
use. The following table summarizes the results. The last row (8 pixels
wide) is the size of the standard Topaz font, for reference. The values are
given as character-per-line x lines-per-screen.
Font HIRES Point Size LORES Point Size
Width 6 7 8 6 7 8
----------------------------------------------------------
4 75 x 31 75 x 26 75 x 23
5 123 x 31 123 x 26 123 x 23 60 x 31 60 x 26 60 x 23
6 103 x 31 103 x 26 103 x 23
7 88 x 23
8 77 x 23 37 x 23
As you can see, the LoRes-4,8 font brings the low-resolution screen up to
the same effective character resolution as the standard hires screen using
the Topaz font. Despite the small width of these characters (3 pixels plus
1 for space between characters), the 7 and 8 point versions are quite
readable, though the 6 point version is less effective.
