- % The essential parts of this macro appeared in {\it TUGboat, Volume 3, No. 1}
- % in the note: "DISPLAY OF A FONT IN TABLE FORM." by Roger L. Beeman.
- % This version was rewritten by Pierre A. MacKay to take advantage of
- % the new features of \TeX82. It is now interactive, and prompts the
- % user for a font name. If the font is a text font, a sample paragraph
- % is set, which is justified to three times the lower-case alphabet length
- % if that will fit in the overall \hsize. (If the font is a fixed-width
- % font such as "amtt", the sample is set with a ragged right margin.)
- % The sample is leaded 20% over the stated point-size, so that a
- % 10-point font is set 10 on 12. The length of both upper and lower
- % case alphabets is given, along with the height and depth of the
- % lower case alphabet and the height of the upper case alphabet. These
- % last dimensions can be very useful for calculating the size of
- % close-fitting boxes and struts.
- %
- % Non-text fonts are displayed in table form only.
- %
- % If you have \TeX\ running with "plain.tex" loaded,
- % you can start this macro by typing "tex fontbl" and you will be prompted
- % for the rest

- The design of low-resolution typefaces is complicated by the need
- to achieve two different and rather incompatible ends. A font which is
- exclusively intended for Office Automation equipment should be designed
- to make the very best use of that environment. Its proportions, balance,
- shading and letter-spacing can and indeed must be fitted to exact
- pixel-bound\-aries, whe\-ther or not the refinements of anti-aliasing are
- used.
-
- A low-resolution font which was created primarily as the proof-copy
- imitation of an associated high-resolu\-tion font will never be quite
- so precisely matched to its environment. Its contours will necessarily be
- determined by exact pixel-boundaries, but often not in the way we might
- prefer. It need not be sloppy, but it can never be so well tuned as
- a font of the first variety. It is a poor Platonic reflection of an
- idea that cannot be fully known except in the dazzling light
- of high-resolution typesetting. The vast majority of fonts produced
- with METAFONT belong to this second variety. A low-resolution
- METAFONT character should be judged for what it is, and not for what
- it has never claimed to be.
