The EM font set -itself is available from Y&Y, Inc. - -Background: -=========== - -Do you: - - (1) like the look of Computer Modern (CM) fonts; but - (2) need ready-made accented characters for proper hyphenation; and - (3) need scalable outline fonts (a.k.a. `PostScript' or `ATM' fonts)? - -Then the EM font set is for you. The character shapes are from Computer -Modern, yet the glyph complement is much larger -- including numerous -ready-made accented and composite characters -- and the fonts are in -scalable Adobe Type 1 format (as opposed to METAFONT based PK bitmaps). - -The EM fonts also satisfy the needs of non-TeX users desireous of the CM -look, because they appear to the operating system as plain vanilla text -fonts, and so can be easily used with applications other than TeX. - -The EM font set: -================ - -The EM font set contains 57 text fonts based on the text fonts in Knuth's -Computer Modern font (CM) set. It also contains 13 math italic fonts based -on the math italic fonts in CM and AMS font sets. The EM text fonts -have a much larger glyph set than the corresponding CM fonts. - -Each CM text font has about 117 usable glyphs for text (plus eleven -Greek letters). The EM fonts add over 90 ready-made composites and -numerous other `missing' glyphs to bring the total number of glyphs to -over 300. This makes it possible, e.g., to use these fonts with -T1 (Cork) encoding, or LY1 (TeX 'n ANSI) encoding, or LM1 (Textures) -encoding. The AFM files show the actual glyph complement available. - -Note that the EM fonts are set up as normal text fonts, unlike the CM fonts -- -all of which have to be set up as pi/math/symbol/decorative/non-text since -CM fonts use there own unusual character layout and do not have anywhere -near the `standard' complement of 228 glyphs expected of a text font. - -Treated as text fonts, the EM fonts are reencoded to platform -specific encoding when installed on operating systems with -system-level support for scalable fonts, such as Windows and Macintosh. -Consequently, for optimum use with TeX, you need a system that can -reencode fonts `on the fly' (or you need to `hard reencode' the PFB -and PFM files using the REENCODE and AFMtoPFM utilities, or use the -reencoding feature of psfonts.map for DVIPS when printing to PS printers). - -The EM text fonts are used in conjunction with some of the CM math fonts. -CM math fonts do not contain upright uppercase Greek letters -- these are -normally taken from the roman text fonts (CMR* and CMBX*). Included in the EM -font set are EMMI* math italic fonts which have these irksome upright -uppercase Greek letters in character code positions 208 - 218. Note that -this is the same scheme used in the MathTime font set, and similar to the -scheme used with the Lucida Bright + Lucida New Math font set when the Lucida -Bright Expert set is not available. - -The names of the EM fonts are derived directly from those of the CM fonts. -So, for example, EMR17 is based on CMR17 --- with close to two hundred -glyphs added. And EMMI10 is based on CMMI10 --- with upright Greek added. - -Relation to the EC font set: -============================ - -The "European Computer Modern" (EC) font set was defined to add -ready-made accented characters to CM, including those needed for some -Eastern European languages. In order to make space for these -characters, many typographically important glyphs had to be banished -to "text companion" (TC) fonts. - -The new EM font set differs from the EC font set in several ways: - -(1) The EC font set is unmanageably large (500 to 600 fonts), making it - unlikely that a well hinted version will become available, and - cluttering operating system files with font listings. - -(2) The EC font set uses fixed encoding, just like CM fonts, except - it is hard wired to T1/Cork encoding instead of OT1/TeX Text encoding. - This means it is less flexible and harder to use with non-TeX applications. - -(3) EC fonts are hard-wired for T1/Cork encoding. - EM text fonts have a larger glyph complement covering several encodings - including T1, LY1, LM1, Windows ANSI, and various ISO standard encodings. - -(4) The metric files for EC fonts have a problem with kerning for - quotation marks. The EM fonts are setup to deal correctly with - "boundary character" kerning for both left and right quotation marks. - -(5) The metric files for EC fonts include a few errors, such as incorrect - sign on a few kerning pairs. These have been fixed in the EM font set. - -(6) The EM fonts use the old germandbls from the CM fonts instead of the - redesigned one in EC. - -(7) The EM font metrics match the CM font metrics exactly for characters that - occur in CM. EC font metrics differ slightly from CM. - -As a result EM is not a "drop in" replacement for EC - it is better. - -NOTE: the following is largely adapted from David Carlisle's type1cm.txt - -Using the LaTeX support for the EM font set -=========================================== - -The default way of using the `em' package is as a LaTeX package file. -Install em.sty as described below and then just add - -\usepackage[T1]{em} or \usepackage[LY1]{em} or \usepackage[LM1]{em} - -to your document. This will override the definitions for all the fonts -and so the standard fd files are not used. This will cause LaTeX -to use the em fonts, and will also call the fontenc package to switch -to the requested encoding (T1/Cork, or LY1/TeXnANSI, or LM1/Mac). - -Installation Instructions: -========================== - -IMPORTANT NOTE: we supply a ready-made em.sty file so the following -`unpacking' is actually not normally needed; unless you require some -particular customization. - -The installation is controlled by the file em.ins which you may want to -edit in two places. - -1) If you do not have the AMS Font set available in scalable form then - remove the `%' from the line %\def\ams{} - This will cause a more restricted font specification to be used. - - If you do not have the `AMS Extra' font set available in scalable form - (i.e. msam6, msam8 and msam9 in addition to msam5, msam7 and msam10) - then remove the `%' from the line %\def\ams{ams} - -2) If after reading the warning above regarding *.fd files, you decide to - make a set of fd files, remove the `%'from the line %\makefdtrue - -Then run TeX (or LaTeX) on the file em.ins. A package file em.sty (and -perhaps a set of fd files - see above) will be produced which you should -place in a directory where TeX looks for input files. (Alternatively, add -the directory containing these files to the list in the TEXINPUTS -environment variable; or the format specific environment variable LATEX). - -Appendix A: Font sizing -- discrete or continuous? -================================================== - -LaTeX separates its internal notion of font specification from the external -fonts available on the system by means of `Font Shape Specifications', that -are normally held in `Font Descriptor' (fd) files. - -The fd files that come with LaTeX that refer to the standard Computer Modern -set (and the related AMS set) are based on the classical bitmap fonts which -are available in discrete `magstep' sizes only. For instance, the -specification of the main roman font is - - \DeclareFontShape{OT1}{cmr}{m}{n} - { <5> <6> <7> <8> <9> <10> <12> gen * cmr - <10.95> cmr10 - <14.4> cmr12 - <17.28><20.74><24.88>cmr17}{} - -which says that no font is available at 10.5pt (LaTeX will substitute the -nearest available size if you ask for this) and similarly the font is not -available at all above 25pt. - -Such restrictions are essential with bitmap fonts to save generating huge -numbers of bitmaps for any size that might be requested, however with -scalable versions of the fonts these restrictions are not really needed. -For instance the equivalent definition here is: - -\DeclareFontShape{LY1}{cmr}{m}{n}{ - <-6> emr5 - <6-7> emr6 - <7-8> emr7 - <8-9> emr8 - <9-10> emr9 - <10-12> emr10 - <12-17> emr12 - <17-> emr17 - }{} - -which means that you can (although some may consider it bad style) go -\fontsize{10.345pt}{12pt}\selectfont and be given a suitably scaled version of -emr10 and a baseline setting of 12pt. Similarly if you really want, you can -go \fontsize{2cm}{2.5cm}\selectfont and use emr17 scaled to 2cm height for a -special display context. - -Appendix B: Technical note about the Font Shape specifications used: -========================================================================== - -David Carlisle consistently specifies that given a requested size, the -largest available font size smaller than (or equal to) the requested size -should be used and then enlarged to the requested size. The exception being -sizes smaller than the smallest available font, which use a reduced version -of that font. The rationale for this is that enlarging a small font -typically produces a rather `fat' font, but something readable, whereas -shrinking a font may produce something unreadable quite quickly, particulary -since the strokes in Computer Modern - and hence European Modern - are -already quite thin. - -So for msam (if `extra' is not specified) he used: - -\DeclareFontShape{U}{msa}{m}{n}{ - <-7> msam5 - <7-10> msam7 - <10-> msam10 - }{} - -That is, for sizes strictly below 7pt use msam5, 7pt to (less than) 10pt -use msam7 and sizes 10pt and above use msam10. - -This differs from the specification that the AMS use for the scalable -AMS fonts (used by the psfonts option to the amsfonts package). They use - -\DeclareFontShape{U}{msa}{m}{n}{ - <-6> msam5 - <6-8> msam7 - <8-> msam10 - }{} - -This scheme has the advantage of minimising the scaling used, so for instance -a 9pt request is satisfied by msam7 scaled up to 9 by this package, but by -msam10 scaled down to 9 by the AMS package. - -In practice this is not likely to make a difference that anyone might notice, -but it could in principle affect line breaks etc, so David thought that it -should be mentioned here. - --------------------------------------------------------------------------------- -(TM) European Modern is a trademark of Y&Y, Inc. http://www.YandY.com ---------------------------------------------------------------------------------
