It contains notes about various commercial font houses. Adobe Systems, Inc. =================== Adobe Systems Incorporated develops, markets, and supports computer software products and technologies that enable users to create, display, print, and communicate electronic documents. Adobe licenses its technology to major computer and publishing suppliers, and markets a line of type and application software products. Compugraphic ============ See "Miles, Agfa Division" designOnline(tm) ================ Home of Alphabets, Inc., designOnline is the online resource for design. The majority of the interactivity is happening on [their] FirstClass server, currently available by dialup and across the Internet. Miles, Agfa Division ==================== Compugraphic which was for a while the Compugraphic division of Agfa, is now calling itself "Miles, Agfa Division" (yes, the Miles drug company), since CG's off-shore parent Agfa has been absorbed by Miles. So typographically speaking, Compugraphic, CG, Agfa, A-G ag, and Miles all refer to the same company and font library. Their proprietary fonts are still CG Xyz, but the name is Miles Agfa. Quadrat Communications ====================== Quadrat Communications is a digital type foundry based in Toronto, Ontario, Canada. [David Vereschagin] began creating and designing type a few years ago, intrigued by the new possibilities presented by Altsys's Fontographer software. [His] first project was the plain style of Clear Prairie Dawn, a sans serif text face, which took three years to complete. As well as designing [his] own faces, [he's] also available for the creation of custom faces. Subject: 1.2. What's the difference between all these font formats? This question is not trivial to answer. It's analogous to asking what the difference is between various graphics image file formats. The short, somewhat pragmatic answer, is simply that they are different ways of representing the same "information" and some of them will work with your software/printer and others won't. At one level, there are two major sorts of fonts: bitmapped and outline (scalable). Bitmapped fonts are falling out of fashion as various outline technologies grow in popularity and support. Bitmapped fonts represent each character as a rectangular grid of pixels. The bitmap for each character indicates precisely what pixels should be on and off. Printing a bitmapped character is simply a matter of blasting the right bits out to the printer. There are a number of disadvantages to this approach. The bitmap represents a particular instance of the character at a particular size and resolution. It is very difficult to change the size, shape, or resolution of a bitmapped character without significant loss of quality in the image. On the other hand, it's easy to do things like shading and filling with bitmapped characters. Outline fonts represent each character mathematically as a series of lines, curves, and 'hints'. When a character from an outline font is to be printed, it must be 'rasterized' into a bitmap "on the fly". PostScript printers, for example, do this in the print engine. If the "engine" in the output device cannot do the rasterizing, some front end has to do it first. Many of the disadvantages that are inherent in the bitmapped format are not present in outline fonts at all. Because an outline font is represented mathematically, it can be drawn at any reasonable size. At small sizes, the font renderer is guided by the 'hints' in the font; at very small sizes, particularly on low-resolution output devices such as screens, automatically scaled fonts become unreadable, and hand-tuned bitmaps are a better choice (if they are available). Additionally, because it is rasterized "on demand," the font can be adjusted for different resolutions and 'aspect ratios'. Werenfried Spit adds the following remark: Well designed fonts are not scalable. I.e. a well designed 5pt font is not simply its 10pt counterpart 50% scaled down. (One can verify this by blowing up some small print in a copier and compare it with large print; or see the example for computer modern in D.E. Knuth's TeXbook.) Although this fact has no direct implications for any of the two methods of font representation it has an indirect one: users and word processor designers tend to blow up their 10pt fonts to 20pt or scale them down to 5pt given this possibility. Subtle details, but well... LaserJet .SFP and .SFL files, TeX PK, PXL, and GF files, Macintosh Screen Fonts, and GEM .GFX files are all examples of bitmapped font formats. PostScript Type 1, Type 3, and Type 5 fonts, Nimbus Q fonts, TrueType fonts, Sun F3, MetaFont .mf files, and LaserJet .SFS files are all examples of outline font formats. Neither of these lists is even close to being exhaustive. To complicate the issue further, identical formats on different platforms are not necessarily the same. For example Type 1 fonts on the Macintosh are not directly usable under MS-DOS or Unix, and vice-versa. It has been pointed out that the following description shows signs of its age (for example, the eexec encryption has been thoroughly hacked). I don't dispute the observation and I encourage anyone with the knowledge and time to submit a more up to date description. It has further been suggested that this commentary is biased toward Kingsley/ATF. The omission of details about Bitstream (and possibly Bauer) may be considered serious since their software lies inside many 3rd-party PostScript interpreters. The moderators of this FAQ would gladly accept other descriptions/ explanations/viewpoints on the issues discussed in this (and every other) section. [Ed Note: Liam R. E. Quin supplied many changes to the following section in an attempt to bring it up to date. Hopefully it is a better reflection of the state of the world today (12/07/92) than it was in earlier FAQs] Henry Schneiker <reachable electronically?> wrote the following description of the differences between several scalable font technologies: ((( semi-quote ))) There has been a lot of confusion about font technologies in recent times, especially when it comes to Type 1 versus Type 3 fonts, "hints," PostScript compatibility, encryption, character regularizing, kerning, and the like. * Encryption (eexec) All fonts produced with Adobe's font technology are protected through data encryption. The decryption is provided by the `eexec' (encrypted execute) PostScript operator and, until recently, was only present in Adobe's licensed PostScript. Adobe has published the details of the Type 1 font format in the `Black Book', Adobe Type 1 Font Format (version 1.1), Adobe Systems Inc., 1990. The encryption was mainly used because of font copyright problems; unencrypted fonts can also be used, but these tend to use an efficient binary encoding, also in documented the Type 1 book, and so are still not readable PostScript. * Type 1, Type 3, and Type 5 font formats There are generally three font formats used in Adobe PostScript printers: Type 1, Type 3, and Type 5. Type 1 fonts are Adobe's downloadable format. Type 3 fonts are third-party downloadable format. Type 5 fonts are the ROM-based fonts that are part of your printer. There is no functional difference between a Type 1, Type 3, or Type 5 font. A Type 3 font can do anything a Type 1 or Type 5 font can do. The only real difference between them is where the `BuildChar' routine comes from. For Type 1 and Type 5 fonts it's built into the printer. For Type 3 fonts it's built into the font. In other words, anything a Type 1 font can do a Type 3 font can also do. [Ed note: the reverse is not true. Type3 fonts can do things that Type1 fonts cannot. But they aren't hinted...] When PostScript is asked to generate a character, PostScript looks in the font's dictionary for FontType. If FontType is 1 or 5 PostScript executes an internal routine that knows how to interpret the font data stored in CharStrings. If FontType is 3 PostScript executes the routine BuildChar from the font's dictionary to interpret the font data (often stored in CharStrings). However, each BuildChar routine is written to read data formatted in a method convenient to the vendor. Adobe, Altsys, Bitstream, and Kingsley/ATF all format their font data differently and, hence, have different BuildChar routines. [Ed note: relative hard disk efficiency of Kingsley vs. Adobe fonts deleted on 12/07/92] Type 5 fonts are special in that they often include hand-tuned bitmaps for the commonly used sizes, such as 10- and 12-point. Other sizes are generated from the outlines in normal fashion. Don't confuse Type 1, Type 3, and Type 5 fonts with Bitstream's Type A, Type B, Type C, and Type F. They are not the same and serve only to confuse the issue. * Resolution `hints' When a character is described in outline format the outline has unlimited resolution. If you make it ten times as big, it is just as accurate as if it were ten times as small. However, to be of use, we must transfer the character outline to a sheet of paper through a device called a raster image processor (RIP). The RIP builds the image of the character out of lots of little squares called picture elements (pixels). The problem is, a pixel has physical size and can be printed only as either black or white. Look at a sheet of graph paper. Rows and columns of little squares (think: pixels). Draw a large `O' in the middle of the graph paper. Darken in all the squares touched by the O. Do the darkened squares form a letter that looks like the O you drew? This is the problem with low resolution (300 dpi). Which pixels do you turn on and which do you leave off to most accurately reproduce the character? All methods of hinting strive to fit (map) the outline of a character onto the pixel grid and produce the most pleasing/recognizable character no matter how coarse the grid is. [Ed note: deleted some paragraphs that are no longer true. Times change...] * Optical Scaling Optical Scaling modifies the relative shape of a character to compensate for the visual effects of changing a character's size. As a character gets smaller, the relative thickness of strokes, the size of serifs, the width of the character, the inter-character spacing, and inter-line spacing should increase. Conversely, as a character gets larger, the relative thickness, widths, and spacing should decrease. Contrast this with linear scaling, in which all parts of a character get larger or smaller at the same rate, making large characters look wide and heavy (strokes are too thick, serifs are too big) while small characters look thin and weak. * Kerning As applied to PostScript fonts, kerning refers to kern pairs. A kern pair specifies two characters (e.g., A and V) and the distance to move the second character relative to the first. The typical use of a kern pair is to remove excessive space between a pair of characters. However, it may also be used to add space. * PostScript clones There are currently several printer manufacturers on the market with PostScript clones. To be viable, a PostScript clone must comply with the `red book' (PS Language Reference Manual). In order to avoid paying royalties to Adobe, and because Adobe's Type 1 font format was originally proprietary, many PostScript interpreters use some other font format. Sun uses F3, and some other vendors use Bitstream's Speedo format, for example. The only real problem this causes is that the widths of characters (the `font metrics') may vary from Adobe's, so that programs that assume the Adobe character widths will produce poor quality output. Bitstream fonts used to be particularly bad in the early days, but they and most or all of the other vendors have solved those problems. * Apple TrueType [Ed note: formerly "Royal (`sfnt')"] format and System 7 Apple's new System 7.0 supports a new format of outline font that will allow high-quality characters of any size to be displayed on the screen. TrueType stores font outlines as B-spline curves along with programmed resolution hints. B-spline curves are faster to compute and easier to manipulate than the Bezier curves used in PostScript. Adobe is not going to support Apple's new format by converting the Adobe/Linotype library to B-spline format. There are two reasons for this: First, there is no support for font encryption (yes, the hooks are there, but nothing is implemented). Second, Adobe does not want to dilute PostScript and its font library. However, the Macintosh is too big a market to simply turn away from. Therefore, Adobe will provide its Font Manager to display its own fonts on the Mac screen. Apple ships Adobe's ATM for this purpose. ((( unquote ))) Subject: 1.3. What about "Multiple Master" fonts? Multiple Master Fonts are an extension to the Adobe font format. providing the ability to interpolate smoothly between several "design axes" from a single font. Design axes can include weight, size, and even some whacko notions like serif to sans serif. Adobes' first Multiple Master Font was Myriad - a two-axis font with WEIGHT (light to black) on one axis, and WIDTH (condensed to expanded) along the other axis. In the case of Myriad, there are four "polar" designs at the "corners" of the design space. The four designs are light condensed, black condensed, light expanded, and black expanded. Given polar designs, you can set up a "weight vector" which interpolates to any point within the design space to produce a unique font for a specific purpose. So you can get a "more or less condensed, somewhat black face". Multiple Master Fonts can be used on any PostScript printer. Multiple Master Fonts need a new PostScript operator known as makeblendedfont. The current crop of Multiple Master Fonts supply an emulation of this operator so the printer doesn't need this operator. A short tutorial on Multiple Master Fonts and makeblendedfont appears in PostScript by Example, by Henry McGilton and Mary Campione, published by Addison-Wesley. Danny Thomas contributes that there are a few PostScript interpreter (version)s which have bugs that appear with the emulation of the makeblendedfont operator used to support Multiple Master fonts. There weren't many exhibiting this problem, though it may have happened even with one Adobe interpreter. Subject: 1.4. Is there a methodology to describe and classify typefaces? There is a standard, Panose, but it is mostly ignored by typographers (not because it's bad, just because they don't need it). The Panose system is documented, among other places, in the Microsoft Windows 3.1 Programmer's Reference from Microsoft Press. The ISO also has a scheme, but it is not Panose. At least one book by a respected authority, Alexander Lawson, Printing Types: An Introduction, describes another, less rigorous system [ed: of his own], which is exposited in "An Introduction" and used without exposition in his later "Anatomy of a Typeface". There is another book, Rookledges International Typefinder, which has a very complete system that uses tell-tales of individual glyphs as well as overall style to index most known faces right in the book. J. Ben Leiberman has another book on type face description. Terry O'Donnell adds the following comments: The current ISO system was initiated (I believe) by Archie Provan of RIT--a successor to Mr. Lawson. Whereas in typographic practice or teaching--only a high level classification is necessary - times have changed and the current ISO system aims to accomplish something beyond the high level. A major goal is to aid software to help users make selections. For example, a naive user might ask for all fonts on a font server which have a Roman old style appearance. Another goal would be to help users with multi-lingual text: a user creating a document in English using e.g. Baskerville wants to know what Arabic or Japanese language font on his system/file server would harmonize well with the Baskerville. It is not all in place yet--but the more detailed ISO classes--and the current addition of non-latin typefaces--are an attempt to address this issue. A second goal is to help with the font substitution problem. Neither ISO or Panose address the metrics issues in font substitution--but both might aid software in picking the nearest style of available available fonts. Subject: 1.5. What is the "f" shaped "s" called? Both the "f" with half a crosbar (roman) and the integral sign (italic) are called long-S. Subject: 1.6. What about "Colonial" Typefaces? Why does colonial printing have that "Colonial" feel? ===================================================== Colonial type was either very roughly treated by moist salt air on the crossing and in colonial port cities, or was copied locally by tacky techniques (such as driving used foundry type into soft lead to make very soft deformable matrices), and the paper was very rough, which abrades both the serifs and the hairlines. So except for the best work done with new, european types, the serifs were much smaller, even broken off, than the original founder/punchcutter intended. Thins could be abraded by rough paper to nothingness, esp after humid salt air had leached the hardener out of the alloy. Peter Honig contributes the following alternative explanation of the roughness of colonial types: The roughness of early fonts was caused by several factors: Type was quite expensive and was used for many years (even if somewhat damaged). Also, printing presses would only be set up to print one side of one folio at a time, so you would not need to set more than a couple of pages at once. This meant that the printer did not need as many copies of each character, however, each character got used very frequently. The early casting techniques did not produce as perfect or consistant examples as we have today. That is, the face of a character might not be quite planar with the page, or its sides might not be quite parallel. Lastly, the inks of the past were not as advanced those of today. What fonts are good for mock-colonial uses? =========================================== For example, what fonts have the following features: old-style figures (non-lining numbers), the long s character, slightly irregular shapes (a la type produced by colonial printers), and a decent complement of ligatures. And what about free or cheap faces like this? I don't know if any exist with all of 1-5. As I believe you get what you pay for, especially in fonts, I haven't looked at free and cheap-copy fonts. Microsoft's expansion set for their Win3.1 optional fonts has Garamond Expert & Expert Extensions, which has a good complement of ligatures and I think I remember it having the long ess too. I forget about OSFigs; it should tho'. Monotype's metal faces "16th Century Roman" and "Poliphilus" may be available in digital; if so, they imitate early presswork with early and are very close to what one wants. "A commercial supplier [not yet sampled] is Image Club Graphics in Calgary (1-800-661-9410). It is called Caslon Antique. It is supplied as both roman and italic, together, for $25. They advertise in MacWorld/MacUser/MacBlah. I am unable to tell from abcDEF123 if the numerals are old-style, but I think not. Ligatures? long-S? Not yet known. Guillemots, though, are there. ... Letraset, circa 1977, showing a Caslon Antique with modern numerals, no ligatures, and only UKPounds and German ss extensions." [Ike Stoddard] NB: Caslon Antique is not a Caslon per se: "The last Caslon to mention is that ubiquitous but unrelated Caslon Antique, which possesses no similarity whatsoever to the original. This old reprobate was introduced by Barnhart Brothers of Chicago under the name Fifteenth Century. Its negative reception lasted until about 1918, when, with a simple name change to Caslon Antique, it became the most commonly selected type for reproductions of colonial American printing. It is now seen in everything from liquor advertisments to furniture commercials" [Lawson, 1990,Anatomy] Miles Agfa (Compugraphic) has always had a Caslon Antique; I don't know if it is available for TrueType or Type 1, but Agfa has been doing TrueType bundles at reasonable prices. [wdr] Peter Honig contributes the following suggestions: Name Year Irreg. Long S OSfig Comment --- --- ----- ----- ---- ------ * Poliphilus A cleaned-up reproduction of type from 1499. It's only slightly irregular and does not contain the long S, but does have old style figures. From Italy, founded by Francesco Griffo. * Old Claude An exact reproduction of Garamond from 1532. It is irregular and does not contain the long S, but it does have old style figures. From France, founded by Claude Garamond. * Blado An exact reproduction of type from 1539. It is irregular and does not contain the long S, but it does have old style figures. From Italy, founded by Antinio Blado (designed by Ludovico delgi Arrighi). * Van Dijck An exact reproduction of type from the 1660s. It is irregular and does not contain the long S, but it does have old style figures. From Holland, founded by Van Dijck. * Adobe Caslon A cleaned-up reproduction of type from the 1720s. It isn't irregular but it does contain the long S, old style figures, and several ligatures. From England, founded by William Caslon. Blado, Poliphilus, and Van Dijck are available from Monotype. Adobe Caslon is available from Adobe. Old Claude is available from Letter Perfect. In my opinion, Old Claude is font that is worthy of close attention. Although it lacks the long S, it is VERY accurately reproduced. Although Adobe Caslon is not irregular, it has a great set of authentic ornaments from the Renaissance and Baroque. It is also the only set that I am aware of, that has the long S and its ligatures. [Bill Troop notes: I do not believe that Monotype ever had a font called 16th Century Roman. You are thinking of a private face created by Paul Hayden-Duensing for his private press based on old Italian punches. It is very rough indeed, but I can assure you no Colonial printer had a typeface as stylish. Poliphilus does indeed exist in digital form, and is fairly faithful, but again is far too stylish to give the proper feel of US Colonial printing. Nor is Antique Caslon, so called, anything to do with the Caslon types used by American printers-except those who used this bogus type at the end of the 19th century. Monotype Bell is a faithful copy of a font that was actually used in the US, but it is far more modern than the Caslon types. Nobody has yet done a really authentic Caslon, and it is a curious fact, but none of the Caslon revivals, in any of metal, photo, or digital formats, has ever been based on the best Caslon sizes. I have been toying with such a revival. Monotype Van Dijk can hardly be called a faithful copy of a metal font; the outlines are far more regular, for instance, than what Monotype did for Bell. In addition, the less interesting forms of the lower case f and f-ligatures were chosen for the digital version, and the alternate f was not supplied. That makes it a very uninteresting font to use in digital form. In addition, the italic has been unbelievably badly spaced in the digital version. (Harry Carter complained about the spacing in the 13pt Roman in the metal version.) For anyone wishing to recreate the feel of early-to-mid 18th century printing, a battered, sensitive revival of Caslon would be desirable. The Giampa version is interesting, but is based on a poor model. ] What fonts could a colonial printer have had? ============================================= According to D.B.Updike in the classic reference "Printing Types: Their History, Forms & Use", he indicates that most colonial work was with types of the Caslon Old Style fonts and cheap copies of same in the 18th C. Before that, it would have been the older Dutch & English faces, almost always lagging English tastes. If you can find the Oxford Fell types, they are classic Dutch-as-used-by-englishmen. Anything with a Dutch moniker and the Oldstyle adjective is probably ok; Van Dijck if you find it, say (died 1673). Ben Franklin recommended Caslon faces. But these were not available in England before 1720, first full broadside in 1734. Lawson declares that the first printing of the Declaration of Independance was in Caslon. Wilson's Scotch Modern was the "modern" font that surfaced in quantity in america. If the Scotch Roman your vendor has is sort-of like-Bodoni but nicer than his Bodoni, that's it. It wasn't available until late 1700s, though. Subject: 1.7. What is "Point Size"? This article was constructed from a posting by William D. Ricker from Sep 1992. In general terms, point size is a relative measure of the size of a font. It used to have a more concrete meaning in the "old days" of typeography. In the world of Photo-typesetters and digital fonts, the distance from the top of the tallest ascender to the bottom of the longest descender is only an approximate lower bound on the point size of a font; in the Old days, it was almost always a firm lower bound, and there was warning on the exception. Point-size is the measure of default or minimum inter-baseline distance; inter line distance in absense of leading, a/k/a "set solid". If you don't know if the text was set solid or leaded, you can't tell the point-size with a measuring glass unless you know if the type design includes built-in space betweed adjacent, set-solid lines. Exceptions to the points size equals ascender to descender size rule: * In metal, there was usually a little room between the highest and lowest corners of the face and the body size, so that the Matrix was completely molding the face and not relying on the mold-body to form a vertical side to the printing face--since a bevel or beard is desirable for impression and strength. * If the designer of a face thinks it should always be set leaded, s/he may choose to include the minimal leading in the design, in which case it is included in the base point size, and no capital, lowercase-ascender, or lowercase-descender will get very near the edges. * In some faces the capitals are taller than the ascenders, and others vice versa. (Vertical sticks on capitals are called stems, not ascenders.) A minimum point size estimate would normally be the height of the font's "envelope", to borrow from Avionics/Aeronautics. * The point size of a "Titling Face" may not include descenders; in which case the Q's tail hangs off the body as a vertical kern. Such a face in metal usually has "Titling" in the name, although sometimes the fact that only capitals are available is all the hint given. ([William D. Ricker's] metal font of Ray Shaded, cast on a Monotype Display caster, has "vertical kerns" if you will: the hanging shaded tail of the Q and some punctuation below the 24pt body, because it has no lower-case. It might be better described as being 36/24, thirty-six point type cast on a twenty-four point body, since the cap A is about the height and density of a Ultrabold 36pt A in many other fonts. It would be called 36/24 Caps if a lowercase had been cast on a 36 point body, but since only UC was ever cut, as UC-only titling, it was standardly issued and refered to as a 24 point titling--much to the confusion of non-cognoscenti.) * The Continental Point, a/k/a the Didot point, (and its Pica Em equivalent, the Cicero) is just a hair longer. 15 Ciceros=16 Picas, 15 Didots=16 Points. So type which is imported or cast from imported matrices has been, and still is, cast on the next size larger body in anglo-american points. So an 11D/12 or 12D/14 type will look larger than a similar 12pt font but smaller than a simlar 14pt font, by about a point of fixed built-in leading that the designer didn't intend. What happened when these faces were converted to photo and digital composition, I don't know. (I could find out.) Probably some were scaled to American sizes proportionally from the european masters, some copied from the American castings with built-in leading to ease conversion, and some were probably done both ways at different conversion houses. Net result: unless you know it's Adobe Times Roman or whatever and just want to know what point size & leading options were, you can't measure the size with a definition and an optical micrometer. The defnition is embodied/manifested in the typesetting "hardware", even if it is software, not the product. Knuth's Assertion ================= What about Knuth's assertion that point size is "a more-or-less arbitrary number that reflects the size of type [a font] is intended to blend with"? That statement is true only in the context of MetaFonts. MetaFonts (and this definition) are perfectly adequate for Knuth's purposes but not fully descriptive of all of typography. And definitely not conformant to established usage. This is not meant to condemn heterodoxy, but just to warn that while the ASCII markup notations in Knuth's "Second Great Work" [TeX and MetaFont] are even more widely disseminated than his wonderful coinage of mathematical notations in "The First Great Work" [The Art of Computer Programming, volumes I, II, and III], MetaFont has not been accepted as an encoding for all useful fonts for the future, and the defintions of font characteristics in MetaFont context must be taken with a large grain of salt when used with fonts outside the MetaFont font-generation paradigm. Knuth's quotation, when applied to a (non-MetaFont) font designer, overstates the arbitrariness of the design choice; the designer was stating in the old days that you'd need a saw, a file, or a caster with his matrices if you wanted to use negative leading to set his type closer than he wanted to see it set; and today, in Photo/digital composition, the designer is either indicating the opinion of the original metal-head or his own design advice as to what the minimum distance between adjacent baselines should be. Also, point size is very poor predictor of blending, except in a mechanical sense in terms of not-overflowing the same rectangles. Some faces to blend in the same line with 12 point type will need to be 10/12 or 14/12, due to differences in the way they fill the space. (The overall leading should fit the body type.) Harmony and contrast of overall color, shape, style, etc. are much more important considerations for blending than body-size. (For two types to work together, there must be sufficient harmonies between them to work together and sufficent contrasts to be easily distinguished. See Carl Dair's books.) If one wants to understand usage of typographical terms in the general milieu, the Chicago Manual of Style's appendix on Typesetting for Authors is a good capsule presentation of history and terminology; if one wants the nitty-gritty on how digital type does, or at least should, differ and be treated differently from just copies of metal, see Richard Rubinstein, Digital Typography, MIT Press. On type in general, consult D.B. Updike in a library (out of print), or A(lexander) S. Lawson (who covers electronic type in his latest revision!). Subject: 1.8. Where can I get ... fonts. Before I go any farther, let me extol the virtues of the Archie servers. If you need to find something on the net, and you have any idea what it might be called, Archie is the place to go. In North America, telnet to "archie.rutgers.edu" and login as "archie". There are many other servers around the world, any Archie server can give you a list of other servers. There are better documents than this to describe Archie and you should be able to find them from the above starting point. If you have trouble, feel free to ask norm (via Email please, no need to clutter comp.fonts with a query about Archie ;-). In addition to the telnet option, several archie clients exist including a very nice X11 implementation (Xarchie). * Adobe Type 1 Fonts in MS-DOS/Unix Format: ftp://ftp.cica.indiana.edu/pub/pc/win3/ ftp://ftp.cica.indiana.edu/pub/pc/win3/fonts/ ftp://archive.umich.edu/msdos/mswindows/ * Adobe Type 1 Fonts in Mac Format: ftp://mac.archive.umich.edu/mac/system.extensions/font/ ftp://sumex-aim.stanford.edu/info-mac/ * Adobe Type 3 Fonts in Mac Format: ftp://mac.archive.umich.edu/mac/system.extensions/font/ * TrueType fonts in MS-DOS Format: ftp://ftp.cica.indiana.edu/pub/pc/win3/fonts/ * TrueType fonts in Mac Format: ftp://mac.archive.umich.edu/mac/system.extensions/font/ * TeX PK/PXL/GF fonts: The TeX community has its own support groups that can provide better answers to this question.

If you know of other archive sites (the above list is no where near complete) or other formats that are available on the net, please let us know. The sites above represent places where shareware and public domain fonts are available. Many, many typefaces are not available in shareware form. And many shareware faces are less than adequate for a variety of reasons, particularly at small sizes. It seems to be the consensus of the comp.fonts community that "you get what you pay for." If you need a professional quality font, you should probably buy it from a professional. The list of font vendors in Appendix A (annotated with information about non-Roman alphabets) was contributed by Masumi Abe. Masumi was Adobe's Manager of Typographic Marketing for Asia. He has since left Adobe. Many font CDs are now available which offer many fonts for a low cost/font. Subject: 1.9. Where can I get fonts for non-Roman alphabets? As mentioned above, the list of font vendors is annotated with information about non-Roman alphabets. Commercially, Masumi suggests that Linguists' Software is the current [ed: as of 7/92] leading supplier of non-Roman fonts. Ian Tresman contributes: The Multilingual PC Directory is a source guide to multilingual and foreign language software, including fonts, for PCs. Over a hundred different languages are included, from Arabic to Hieroglyphics to Zulu. A 1200 word description is available from the publishers, Knowledge Computing, email: 72240.3447@compuserve.com. Subject: 1.10. What about fonts with the International Phonetic Alphabet (IPA) symbols? I summarized Scott Brumage's recent post for the FAQ: Shareware or free (PostScript Type 1 and/or TrueType): ====================================================== * TechPhon Seems to lack some characters and has no zero-offset characters (for accents). * PalPhon A phonetic font which you can get by anonymous ftp from mac.archive.umich.edu. It is called PalPhon. There are actually two fonts: the basic PalPhon and one with additional accents and symbols called PalPi. The package includes some documents on using the fonts as well. * SIL-IPA SIL-IPA is a set of scalable IPA fonts containing the full International Phonetic Alphabet with 1990 Kiel revisions. Three typefaces are included: * SIL Doulos (similar to Times) * SIL Sophia (similar to Helvetica) * SIL Manuscript (monowidth) Each font contains all the standard IPA discrete characters and non-spacing diacritics as well as some suprasegmental and puncuation marks. Each font comes in both PostScript Type 1 and TrueType formats. The fonts are also available for Microsoft Windows. These fonts were designed by the Printing Arts Department of the Summer Institute of Linguistics, Dallas, Texas. Shareware or free (TeX): ======================== METAFONT sources of the phonetic symbols developed by Tokyo-Shoseki-Printing and Sanseido are available. The font contains all of IPA (Internatioanl Phonetic Alphabet) symbols. You can get phonetic symbols METAFONT (named TSIPA) from ftp://ftp.foretune.co.jp/pub/tools/TeX/ The IP address for ftp.foretune.co.jp is 133.123.1.2. Commercial: =========== Linguist's Software Adobe (ITC Stone Phonetic [#255], Times Phonetic [#278]) This is Info file compfont.info, produced by Makeinfo-1.55 from the input file FAQ.texinfo. Subject: 1.11. How can I convert my ... font to ... format? Conversion from one bitmapped format to another is not generally too difficult. Conversion from one scalable format to another is very difficult. Several commercial software packages claim to perform these tasks, but none has been favorably reviewed by the comp.fonts community. Converting Between TrueType and Adobe Type 1 Formats ==================================================== This section was constructed from postings by Primoz Peterlin and Bert Medley in Sep 1993. There are several commercial tools that will convert between these formats. There are no shareware or free tools that will do the job. See also "Why do converted fonts look so bad?". FontMonger by Ares Software --------------------------- Performs conversion between Adobe Type 1, Adobe Type 3 and TrueType formats in both PC-DOS and Mac flavours, as well as simple glyph editing. Currently at version 1.0.7, patches available via CompuServe. Available for Mac and MS Windows. Commercial product, price \$60-80. Alltype by Atech Software ------------------------- Performs font conversion. A stable product, being on a market for a while. Available for PC-DOS/MS Windows only. Commercial product. Atech is supposedly leaving the business. Fontographer by Altsys Co. -------------------------- Comprehensive package, allowing creation of fonts as well as conversion between formats. Available for Mac and MS Windows. Commercial product, price cca. \$270 (PC version). Metamorphosis by Altsys Co. --------------------------- Available for Mac. Commercial product. More info needed. Converting Between Other Scalable Formats ========================================= Many of the programs in the preceding section claim to be able to convert between other formats as well. And there are probably other commercial programs as well. However, as several people have noted, conversion from one scalable format to another is a bad idea. If the original font was well hinted, the converted font will not be. Of course, if the original was poorly hinted, maybe it won't matter much. In an effort to settle a long-running and oft-asked question, I'll be blunt: as of today [6/93], THERE ARE NO NON-COMMERCIAL PROGRAMS WHICH WILL CONVERT FROM ONE SCALABLE FORMAT TO ANOTHER. Not from TrueType to PostScript Type 1, Type 3, Type 5, or any other scalable PostScript format. Not from PostScript Type 1 to TrueType. Not to or from Intellifont. Not to or from Sun F3 format. For specific conversions, check the platform specific parts of the FAQ. Most of the conversions discussed require platform specific tools. Here is a summary of the conversions discussed (and the section in which they appear): Mac Type 1 PostScript To PC Type 1 PostScript (MS-DOS). To TrueType (commercial). PC Type 1 PostScript To Mac Type 1 PostScript (Mac, commercial). To TrueType (commercial). To TeX PK (MS-DOS). TrueType To Type 1 PostScript (Mac and MS-DOS, commercial). To HP LaserJet bitmaps (MS-DOS, hack!). TeX PK To HP LaserJet bitmap softfonts (MS-DOS). HP LaserJet bitmap softfonts To TeX PK (MS-DOS). In addition, Adobe ships a copy of Adobe Font Foundry with all of its fonts which can convert Type 1 fonts into HP LaserJet softfonts. Why Do Converted Fonts Look So Bad? =================================== This section was constructed from postings by Mark Hastings and David Glenn in Aug 1993. With all commercially available conversion tools, converting fonts between scalable formats almost always results in a font inferior to the original. (The rare case where a converted font is not inferior to the original occurs only when the original is a cheap knock-off, and the automatic hinting of the conversion program is better than automatic hinting used in the original!) David Glenn contributes the following analysis: There are a few probable [reasons why converted fonts, especially screen fonts, look inferior to the original]. First off, any font that's converted uses a converting algorithm which will make an exact copy at best. Because no currently available converter even comes close to copying faithfully the manual tweaks and hinting in a font file, you often end up with poor screen fonts and poor output. The only reason that printed output from the converted font looks markedly better than the screen font is that the printed output is at a higher resolution. The converter achieves better results on the higher resolutions because hinting is less important at higher resolutions. Screen fonts are incredibly complex to make well. You have very few pixels to represent a very aesthetic and distinct design. That's why at small sizes almost all typefaces look alike--how do you represent a graceful concave side on the letter "L" for Optima with only 12 pixels in height and one in width? You can't. And that's why most fonts look similar at 10pt, unless they're hand hinted by typograhers. One thing that may come into play when fonts are converted between platforms, for example between PC/Windows format and Mac format, is that fonts are hinted down to a certain number of pixels per em. On a Mac screen (72 dpi) there is a one-to-one correspondence between the ppem and the point size of a font. Under windows, the usual VGA screen is 96dpi and fonts that look good at 8 or 9 pt under windows might look like crap on a Mac 'cuz the fonts weren't hinted below 10 or 11ppem. Also, the conversion programs may have made the appearance worse at some sizes than others. Whenever you convert fonts from one platform to the other keep in mind that: * Your license with the type foundry may or may not allow this. * The font may or may not have the correct character sets in it. * The TT font file may or may not have all the tables necessary. * Your converter may make it so ugly that you don't want to use it... Smoothing Bitmaps ================= This section was constructed from postings by Jason Lee Weiler and Piercarlo Antonio Grandi Enlarging bitmapped images is easy, but enlarging them without creating very jagged edges is much more demanding. There are several possibilities. * If you are interested in programming your own solution, the comp.graphics FAQ will provide pointers to a number of resources that can get you started. * If the bitmaps are in a standard format, the 'xv' tool (an X11 picture viewing tool) includes magnify and smooth functions that may perform adequately. * Commercial tools like Adobe Illustrator, Corel Draw, and many others include tracing functions that can translate some bitmaps into acceptable outlines (which can be enlarged without jaggedness). * The GNU Font Utilities include a tracing tool that may be helpful.
