  • A Font Family Sampler
    A Font Family Sampler Nelson H. F. Beebe Department of Mathematics University of Utah Salt Lake City, UT 84112-0090, USA 11 February 2021 Version 1.6 To assist in producing greater font face variation in university disser- tations and theses, this document illustrates font family selection with a LATEX document preamble command \usepackage{FAMILY} where FAMILY is given in the subsection titles below. The body font in this document is from the TEX Gyre Bonum family, selected by a \usepackage{tgbonum} command in the document preamble, but the samples illustrate scores other font families. Like Computer Modern, Latin Modern, and the commercial Lucida and MathTime families, the TEX Gyre families oer extensive collections of mathematical characters that are designed to resemble their companion text characters, making them good choices for scientic and mathemati- cal typesetting. The TEX Gyre families also contain many additional spe- cially designed single glyphs for accented letters needed by several Euro- pean languages, such as Ð, ð, Ą, ą, Ę, ę, Ł, ł, Ö, ö, Ő, ő, Ü, ü, Ű, ű, Ş, ş, T,˚ t,˚ Ţ, ţ, U,˚ and u.˚ Comparison of text fonts Some of the families illustrated in this section include distinct mathemat- ics faces, but for brevity, we show only prose. When a font family is not chosen, the LATEX and Plain TEX default is the traditional Computer Mod- ern family used to typeset the Art of Computer Programming books, and shown in the rst subsection. 1 A Font Family Sampler 2 NB: The LuxiMono font has rather large characters: it is used here in 15% reduced size via these preamble commands: \usepackage[T1]{fontenc} % only encoding available for LuxiMono \usepackage[scaled=0.85]{luximono} \usepackage{} % cmr Lorem ipsum dolor sit amet, aenean nulla tellus metus odio non maecenas, pariatur vitae congue laoreet semper, nulla adipiscing cursus neque dolor dui, faucibus aliquam quis.

  • An Introduction to the X Window System Introduction to X's Anatomy
    An Introduction to the X Window System Robert Lupton This is a limited and partisan introduction to ‘The X Window System’, which is widely but improperly known as X-windows, specifically to version 11 (‘X11’). The intention of the X-project has been to provide ‘tools not rules’, which allows their basic system to appear in a very large number of confusing guises. This document assumes that you are using the configuration that I set up at Peyton Hall † There are helpful manual entries under X and Xserver, as well as for individual utilities such as xterm. You may need to add /usr/princeton/X11/man to your MANPATH to read the X manpages. This is the first draft of this document, so I’d be very grateful for any comments or criticisms. Introduction to X’s Anatomy X consists of three parts: The server The part that knows about the hardware and how to draw lines and write characters. The Clients Such things as terminal emulators, dvi previewers, and clocks and The Window Manager A programme which handles negotiations between the different clients as they fight for screen space, colours, and sunlight. Another fundamental X-concept is that of resources, which is how X describes any- thing that a client might want to specify; common examples would be fonts, colours (both foreground and background), and position on the screen. Keys X can, and usually does, use a number of special keys. You are familiar with the way that <shift>a and <ctrl>a are different from a; in X this sensitivity extends to things like mouse buttons that you might not normally think of as case-sensitive.
