CM-Super: Automatic Creation of Efficient Type 1 Fonts from Metafont
CM-Super: Automatic creation of efficient Type 1 fonts from METAFONT fonts Vladimir Volovich Voronezh State University Moskovsky prosp. 109/1, kv. 75, Voronezh 304077 Russia [email protected] Abstract In this article I describe making the CM-Super fonts: Type 1 fonts converted from METAFONT sources of various Computer Modern font families. The fonts contain a large number of glyphs covering writing in dozens of languages (Latin-based, Cyrillic-based, etc.) and provide outline replacements for the original METAFONT fonts. The CM-Super fonts were produced by tracing the high resolution bitmaps generated by METAFONT with the help of TEXtrace, optimizing and hinting the fonts with FontLab, and applying cleanups and optimizations with Perl scripts. 1 The idea behind the CM-Super fonts There exist free Type 1 versions of the original CM The Computer Modern (CM) fonts are the default fonts, provided by Blue Sky Research, Elsevier Sci- ence, IBM Corporation, the Society for Industrial and most commonly used text fonts with TEX. Orig- inally, CM fonts contained only basic Latin letters, and Applied Mathematics (SIAM), Springer-Verlag, and thus covered only the English language.

Chapter 1: What is MiKTEX? 1 1 What is MiKTEX? 1.1 MiKTEX Features MiKTEX is a TEX distribution for Windows (95/98/NT/2000). Its main features include: • Native Windows implementation with support for long file names. • On-the-fly generation of missing fonts. • TDS (TEX directory structure) compliant. • Open Source. • Advanced TEX compiler features: -TEX can insert source file information (aka source specials) into the DVI file. This feature improves Editor/Previewer interaction. -TEX is able to read compressed (gzipped) input files. - The input encoding can be changed via TCX tables. • Previewer features: - Supports graphics (PostScript, BMP, WMF, TPIC, . .) - Supports colored text (through color specials) - Supports PostScript fonts - Supports TrueType fonts - Understands HyperTEX(html:) specials - Understands source (src:) specials - Customizable magnifying glasses • MiKTEX is network friendly: - integrates into a heterogeneous TEX environment - supports UNC file names - supports multiple TEXMF directory trees - uses a file name database for efficient file access - Setup Wizard can be run unattended The MiKTEX distribution consists of the following components: • TEX: The traditional TEX compiler. -
About Basictex-2021
About BasicTeX-2021 Richard Koch January 2, 2021 1 Introduction Most TeX distributions for Mac OS X are based on TeX Live, the reference edition of TeX produced by TeX User Groups across the world. Among these is MacTeX, which installs the full TeX Live as well as front ends, Ghostscript, and other utilities | everything needed to use TeX on the Mac. To obtain it, go to http://tug.org/mactex. 2 Basic TeX BasicTeX (92 MB) is an installation package for Mac OS X based on TeX Live 2021. Unlike MacTeX, this package is deliberately small. Yet it contains all of the standard tools needed to write TeX documents, including TeX, LaTeX, pdfTeX, MetaFont, dvips, MetaPost, and XeTeX. It would be dangerous to construct a new distribution by going directly to CTAN or the Web and collecting useful style files, fonts and so forth. Such a distribution would run into support issues as the creators move on to other projects. Luckily, the TeX Live install script has its own notion of \installation packages" and collections of such packages to make \installation schemes." BasicTeX is constructed by running the TeX Live install script and choosing the \small" scheme. Thus it is a subset of the full TeX Live with exactly the TeX Live directory structure and configuration scripts. Moreover, BasicTeX contains tlmgr, the TeX Live Manager software introduced in TeX Live 2008, which can install additional packages over the network. So it will be easy for users to add missing packages if needed. Since it is important that the install package come directly from the standard TeX Live distribution, I'm going to explain exactly how I installed TeX to produce the install package. -

Mmixware a RISC Computer for the Third Millennium Reihe: Lecture Notes in Computer Science
springer.com Donald E. Knuth MMIXware A RISC Computer for the Third Millennium Reihe: Lecture Notes in Computer Science MMIX is a RISC computer designed by Don Knuth to illustrate machine-level aspects of programming. In the author's book series "The Art of Computer Programming", MMIX replaces the 1960s-style machine MIX. A particular goal in the design of MMIX was to keep its machine language simple, elegant, and easy to learn. At the same time, all of the complexities needed to achieve high performance in practice are taken into account. This book constitutes a collection of programs written in CWEB that make MMIX a virtual reality. Among other utilities, an assembler converting MMIX symbolic files to MMIX objects and two simulators executing the programs in given object files are provided. The latest version of all programs can be downloaded from MMIX's home page. The book provides a complete documentation of the MMIX computer and its assembly language. It also presents mini-indexes, which make the programs much easier to understand. A corrected reprint of the book has been published in 1999, X, 550 p. August 2014, replacing the version of 1999.
