Pkfix
The text-producing systems LaTeX and TeX produce DVI files from files written by the user. Those files used to be (and, to a moderate extent, still are) post-processed by a tool called dvips, which converted those DVI files into PostScript files, which are understood by many printers. Some older versions of dvips with embedded bitmapped fonts, which represented letters and symbols as pictures at a fixed resolution (for instance, at 300 dpi). When such files are printed on newer devices (some with resolution of 1200 dpi), the letters of the files that have bitmapped fonts display a remarkably low quality, with jagged lines on curves and diagonals. One solution to this problem is to substitute the bitmapped fonts with scalable fonts (known among PostScript users as Type 1 fonts). To remedy this problem of low quality printing, one can use Heiko Oberdiek's utility called pkfix. The input of pkfix is a PostScript file generated by dvips (with versions at 5.58 or newer) and its outpu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Perl
Perl is a family of two high-level, general-purpose, interpreted, dynamic programming languages. "Perl" refers to Perl 5, but from 2000 to 2019 it also referred to its redesigned "sister language", Perl 6, before the latter's name was officially changed to Raku in October 2019. Though Perl is not officially an acronym, there are various backronyms in use, including "Practical Extraction and Reporting Language". Perl was developed by Larry Wall in 1987 as a general-purpose Unix scripting language to make report processing easier. Since then, it has undergone many changes and revisions. Raku, which began as a redesign of Perl 5 in 2000, eventually evolved into a separate language. Both languages continue to be developed independently by different development teams and liberally borrow ideas from each other. The Perl languages borrow features from other programming languages including C, sh, AWK, and sed; They provide text processing facilities without the arbitrary data-le ...

Cross-platform
In computing, cross-platform software (also called multi-platform software, platform-agnostic software, or platform-independent software) is computer software that is designed to work in several computing platforms. Some cross-platform software requires a separate build for each platform, but some can be directly run on any platform without special preparation, being written in an interpreted language or compiled to portable bytecode for which the interpreters or run-time packages are common or standard components of all supported platforms. For example, a cross-platform application may run on Microsoft Windows, Linux, and macOS. Cross-platform software may run on many platforms, or as few as two. Some frameworks for cross-platform development are Codename One, Kivy, Qt, Flutter, NativeScript, Xamarin, Phonegap, Ionic, and React Native. Platforms ''Platform'' can refer to the type of processor (CPU) or other hardware on which an operating system (OS) or application runs, t ...

LaTeX Project Public License
The LaTeX Project Public License (LPPL) is a software license originally written for the LaTeX system. Software distributed under the terms of the LPPL can be regarded as free software; however, it is not copylefted. Besides the LaTeX base system, the LPPL is also used for most third-party LaTeX packages. Software projects other than LaTeX rarely use it. Unique features of the license The LPPL grew from Donald Knuth's original license for TeX, which states that the source code for TeX may be used for any purpose but a system built with it can only be called 'TeX' if it strictly conforms to his canonical program. The incentive for this provision was to ensure that documents written for TeX will be readable for the foreseeable future and TeX and its extensions will still compile documents written from the early 1980s to produce output exactly as intended. Quoting Frank Mittelbach, the main author of the license: "LPPL attempts to preserve the fact that something like LaTeX is a ...

LaTeX
Latex is an emulsion (stable dispersion) of polymer microparticles in water. Latexes are found in nature, but synthetic latexes are common as well. In nature, latex is found as a milky fluid found in 10% of all flowering plants (angiosperms). It is a complex emulsion that coagulates on exposure to air, consisting of proteins, alkaloids, starches, sugars, oils, tannins, resins, and gums. It is usually exuded after tissue injury. In most plants, latex is white, but some have yellow, orange, or scarlet latex. Since the 17th century, latex has been used as a term for the fluid substance in plants, deriving from the Latin word for "liquid". It serves mainly as defense against herbivorous insects. Latex is not to be confused with plant sap; it is a distinct substance, separately produced, and with different functions. The word latex is also used to refer to natural latex rubber, particularly non-vulcanized rubber. Such is the case in products like latex gloves, latex condoms ...

DVI File Format
The device independent file format (DVI) is the output file format of the TeX typesetting program, designed by David R. Fuchs and implemented by Donald E. Knuth in 1982. Unlike the TeX markup files used to generate them, DVI files are not intended to be human-readable; they consist of binary data describing the visual layout of a document in a manner not reliant on any specific image format, display hardware or printer. DVI files are typically used as input to a second program (called a DVI ''driver'') which translates DVI files to graphical data. For example, most TeX software packages include a program for previewing DVI files on a user's computer display; this program is a driver. Drivers are also used to convert from DVI to popular page description languages (e.g. PostScript, PDF) and for printing. TeX markup may be at least partially reverse-engineered from DVI files, although this process is unlikely to produce high-level constructs identical to those present in the origi ...

Dvips
dvips is a computer program that converts the Device Independent file format (DVI) output of TeX typography into a printable or otherwise presentable form. was written by Tomas Rokicki to produce printable PostScript files from DVI input, and is now commonly used for general DVI conversion. The TeX typesetting system outputs DVI files which are intended to be independent of the output device. In particular, they are not understood by printers and lack information such as font shapes. Thus, a converter (i.e., a backend) is needed to translate from a DVI file to a printer language. Although other DVI backends such as dvilj exist, is one of the most common ways of printing DVI files. Another, more recent solution is the use of pdfTeX to directly generate PDF files, which have readers for most platforms. Given its importance, is a standard part of most TeX distributions, such as teTeX, and TeX Live. By using TeX \special commands, it is possible to directly insert "lite ...

PostScript
PostScript (PS) is a page description language in the electronic publishing and desktop publishing realm. It is a dynamically typed, concatenative programming language. It was created at Adobe Systems by John Warnock, Charles Geschke, Doug Brotz, Ed Taft and Bill Paxton from 1982 to 1984. History The concepts of the PostScript language were seeded in 1976 by John Gaffney at Evans & Sutherland, a computer graphics company. At that time Gaffney and John Warnock were developing an interpreter for a large three-dimensional graphics database of New York Harbor. Concurrently, researchers at Xerox PARC had developed the first laser printer and had recognized the need for a standard means of defining page images. In 1975-76 Bob Sproull and William Newman developed the Press format, which was eventually used in the Xerox Star system to drive laser printers. But Press, a data format rather than a language, lacked flexibility, and PARC mounted the Interpress effort to create a succ ...

Embedded Font
Font embedding is the inclusion of font files inside an electronic document. Font embedding is controversial because it allows licensed fonts to be freely distributed. History Font embedding has been possible with Portable Document Format (PDF), Microsoft Word for Windows and some other applications for many years. LibreOffice supports font embedding since version 4.1 in its Writer, Calc and Impress applications. In word processors Microsoft Word for Windows has permitted font embedding in some document formats since Word 97 (such as .doc or .rtf). But this feature does not work correctly in some Word versions. LibreOffice supports font embedding since version 4.1. This feature is available for the word processor LibreOffice Writer, the spreadsheet application LibreOffice Calc, and the presentation application LibreOffice Impress. Both OpenOffice.org and LibreOffice support font embedding in the PDF export feature. Font embedding in word processors is not widely supported nor ...

Type 1 Font
PostScript fonts are font files encoded in outline font specifications developed by Adobe Systems for professional digital typesetting. This system uses PostScript file format to encode font information. "PostScript fonts" may also separately be used to refer to a basic set of fonts included as standards in the PostScript system, such as Times New Roman, Helvetica, and Avant Garde. History Type 1 and Type 3 fonts, though introduced by Adobe in 1984 as part of the PostScript page description language, did not see widespread use until March 1985 when the first laser printer to use the PostScript language, the Apple LaserWriter, was introduced. Even then, in 1985, the outline fonts were resident only in the printer, and the screen used bitmap fonts as substitutes for outline fonts. Although originally part of PostScript, Type 1 fonts used a simplified set of drawing operations compared to ordinary PostScript (programmatic elements such as loops and variables were removed, much l ...

Font Formats
In metal typesetting, a font is a particular size, weight and style of a typeface. Each font is a matched set of type, with a piece (a " sort") for each glyph. A typeface consists of a range of such fonts that shared an overall design. In modern usage, with the advent of computer fonts, the term "font" has come to be used as a synonym for "typeface", although a typical typeface (or "font family") consists of a number of fonts. For instance, the typeface "Bauer Bodoni" (sample shown here) includes fonts "Roman" (or "Regular"), "Bold" and ''" Italic"''; each of these exists in a variety of sizes. The term "font" is correctly applied to any one of these alone but may be seen used loosely to refer to the whole typeface. When used in computers, each style is in a separate digital "font file". In both traditional typesetting and modern usage, the word "font" refers to the delivery mechanism of the typeface. In traditional typesetting, the font would be made from metal or wood type: ...
