Jun 2022) $ :Copyright: This document has been placed in the public domain. :Abstract: This document covers topics specific to Docutils' LaTeX_ export. .. contents:: .. sectnum:: LaTeX ===== LaTeX__, is a document preparation system for high-quality typesetting. It is most often used for medium-to-large technical or scientific documents but it can be used for almost any form of publishing. There exists a wide selection of `LaTeX Documentation on the net`_ and `books on LaTeX and related topics`_. For an introduction to LaTeX see, e.g., `LaTeX2e for authors`_. __ http://www.latex-project.org/ .. _LaTeX2e for authors: http://www.latex-project.org/guides/usrguide.pdf .. _LaTeX Documentation on the net: http://www.latex-project.org/guides/ .. _books on LaTeX and related topics: http://www.latex-project.org/guides/books.html .. _LaTeX packages: LaTeX document classes and packages ----------------------------------- Unlike HTML with CSS, LaTeX uses one common language for markup and style definitions. Separation of content and style is realized by collecting style definitions in LaTeX classes and packages, or the `document preamble `_. LaTeX document classes and packages (similar to Python modules or C libraries) provide means to extend or modify the LaTeX language by redefining macros or providing new ones. Using the `document class`_ and `style sheet`_ configuration options, you can select from a *huge* selection of classes and packages (standard as well as user contributed) coming with your TeX distribution or available at CTAN_ as well as custom style sheets. .. _CTAN: http://www.ctan.org Docutils specific LaTeX macros ------------------------------ Some Docutils objects have no LaTeX counterpart, they will be typeset using a Docutils specific LaTeX *macro* (command, environment, or length) to allow customization. By convention, special macros use the prefix ``\DU``\ [#]_. The `docutils.sty`_ LaTeX package providing required definitions is part of Docutils ≥ 0.17 and available on CTAN since 2020-09-04. The generated LaTeX documents should be kept processable by a standard LaTeX installation. Therefore fallback definitions are included after the `custom style sheets`_, if a macro is required in the document and the `stylesheet`_ setting does not include "docutils". * Custom `style sheets`_ can define alternative implementations with ``\newcommand``, ``\newenvironment``, and ``\newlength`` followed by ``\setlength``. * Definitions with `raw LaTeX`_ are part of the document body. Use ``\def``, ``\renewcommand`` or ``\renewenvironment``, and ``\setlength``. See the test output standalone_rst_latex.tex_ for an example of the fallback definitions and their use in the document. .. [#] DU for Documentation Utilities = Docutils .. _docutils.sty: https://ctan.org/pkg/docutils Length units ------------ LaTeX supports all `length units`_ defined for Docutils plus the following less common units: :pt: typewriter's (or LaTeX) point (1 pt = 1/72.27 in) :dd: didôt (1 dd = 1238/1157 pt) :cc: cîcero (1 cc = 12 dd) :sp: scaled point (1sp = 1/65536pt) .. attention:: Different definitions of the unit "pt"! * In Docutils (as well as CSS) the unit symbol "pt" denotes the `Postscript point` or `DTP point`. * LaTeX uses "pt" for the `LaTeX point`, which is unknown to Docutils and 0.3 % smaller. * The `DTP point` is available in LaTeX as "bp" (big point): 1 pt = 1/72.25 in < 1 bp = 1/72 in Lengths specified in the document with unit "pt" will be given the unit "bp" in the LaTeX source. In `raw LaTeX`_ and `custom style sheets`_, the `DTP point` must be specified as "bp", while "pt" is interpreted as `LaTeX point`. The default length unit (added by Docutils to length specifications without unit) is the "DTP point". .. _length units: ../ref/rst/restructuredtext.html#length-units PDF generation ============== In most cases, LaTeX code is not the desired end-format of the document. LaTeX offers many ways to generate PDF documents from the LaTeX source, including: _`pdflatex` Generates a PDF document directly from the LaTeX file. Export your document with the _`LaTeX2e writer` (writer name "``latex``", frontend tool rst2latex.py_). _`xelatex` or _`lualatex` The `XeTeX`_ and LuaTeX_ engines work with input files in UTF-8 encoding and system fonts. Export your document with the _`XeLaTeX writer` (writer name "``xetex``", frontend tool rst2xetex.py_). You may need to call latex two or three times to get internal references correct. .. _documentoptions: config.html#documentoptions .. _xetex: http://tug.org/xetex/ .. _luatex: http://luatex.org/ .. _rst2latex.py: tools.html#rst2latex-py .. _rst2xetex.py: tools.html#rst2xetex-py _`rubber` The Rubber__ wrapper for LaTeX and friends can be used to automatically run all programs the required number of times and delete "spurious" files. This includes processing bibliographic references or indices, as well as compilation or conversion of figures. __ https://gitlab.com/latex-rubber/rubber/ Configuration ============= .. contents:: :local: .. _option: Options/Settings ---------------- Options can be specified as * command-line options, or * configuration settings. Run ``rst2latex.py --help`` to get a list of available options; see `Docutils Configuration`_ for details. .. _Docutils Configuration: config.html Classes ------- The `"classes" attribute`_ is one of the common attributes, shared by all Docutils elements. In HTML, the common use is to provide selection criteria for style rules in CSS stylesheets. As there is no comparable framework for LaTeX, Docutils emulates some of this behaviour via `Docutils specific LaTeX macros`_. Due to LaTeX limitations, class arguments are ignored for some elements (e.g. a rubric_). *Inline elements* are handled via the ``\DUrole{}`` macro that calls the optional styling command ``\DUrole«classargument»`` with one argument (the role content). See `custom interpreted text roles`_. *Block level elements* are wrapped in "class environments": ``\begin{DUclass}`` calls the optional styling command ``\DUCLASS«classargument»{}``, ``\end{DUclass}`` tries ``\endDUCLASS«classargument»``. Customization is done by defining matching macros or environments. Example 1: Use small caps font inside elements with class value "custom". *Inline elements* The LaTeX function ``\textsc`` sets the argument in small caps:: \newcommand{\DUrolecustom}[1]{\textsc{#1}} *Block-level elements* The LaTeX directive (macro without argument) ``\scshape`` switches to the small caps font. Its effect is confined to the wrapper ``DUclass`` environment:: \newcommand*{\DUCLASScustom}{\scshape} Example 2: It is even possible to locally redefine other LaTeX macros, e.g. to turn bullet lists with class value "enumerateitems" into enumerated lists:: \newcommand*{\DUCLASSenumerateitems}{% \renewenvironment{itemize}{\begin{enumerate}}% {\end{enumerate}}% } .. rubric:: Notes * Class arguments may contain numbers and hyphens, which need special treatment in LaTeX command names (see `class directive`_). The commands ``\csname`` and ``\endcsname`` or the special command ``\@namedef`` can help with the definition of corresponding macros or environments, e.g.:: \expandafter\newcommand\csname gg1\endcsname{Definition of gg1.} or :: \makeatletter \@namedef{DUCLASSadmonition-test}{…} \makeatother * Elements can have multiple class arguments. In contrast to HTML/CSS, the order of the class arguments cannot be ignored in LaTeX * Class handling differs for some elements and class values: * Class argument values starting with ``align-`` are transformed to "align" argument values. Class argument values starting with ``language-`` set the elements language property. * The table element recognizes some special class values. See section `table style`_. * If the legacy-class-functions_ setting is True, the special macros ``\DUadmonition`` and ``\DUtitle`` are written with a comma separated list of class values as optional argument. .. _"classes" attribute: ../ref/doctree.html#classes .. _legacy-class-functions: config.html#legacy-class-functions LaTeX code ---------- Custom LaTeX code can be placed in `style sheets`_, the `LaTeX preamble`_, the document body (`raw LaTeX`_), or custom templates_. The functional tests that come with Docutils, can serve as example. input: standalone_rst_latex.txt_ (includes files from `tests/functional/input/data`_) expected output: standalone_rst_latex.tex_ .. _standalone_rst_latex.txt: https://sourceforge.net/p/docutils/code/HEAD/tree/trunk/docutils/test/functional/input/standalone_rst_latex.txt .. _tests/functional/input/data: https://sourceforge.net/p/docutils/code/HEAD/tree/trunk/docutils/test/functional/input/data .. _standalone_rst_latex.tex: https://sourceforge.net/p/docutils/code/HEAD/tree/trunk/docutils/test/functional/expected/standalone_rst_latex.tex .. _style sheet: .. _custom style sheets: Style sheets ```````````` A common way of LaTeX customization is the preparation of custom style sheets, either as simple files with LaTeX code snippets or as home-made `LaTeX packages`_ (see the clsguide_ for an introduction on LaTeX package writing). Options: stylesheet_ It is possible to specify multiple style sheets and mix `LaTeX packages`_ with custom style sheets. You cannot specify package options with the stylesheet_ setting. If you need to pass options to the package, use the ``\usepackage`` command in the `LaTeX preamble`_ or a custom style sheet. Example 1: Select Latin Modern fonts with the `lmodern` package:: --stylesheet=lmodern Example 2: Use the `preamble.tex` home-made custom style sheet together with the package `kerkis` (Bookman fonts):: --stylesheet=kerkis,preamble.tex Example 3: Select Palatino fonts with old-style numbers and true small-caps with the LaTeX command :: \usepackage[osf,sc]{mathpazo} in the `LaTeX preamble`_ or `custom style sheets`_. Stylesheet Repository There is a `repository of user-contributed style sheets`_ in the Docutils Sandbox_. .. _clsguide: https://mirrors.ctan.org/macros/latex/base/clsguide.pdf .. _stylesheet: config.html#stylesheet-latex-writers .. _embed-stylesheet: config.html#embed-stylesheet-latex-writers .. _repository of user-contributed style sheets: ../../../sandbox/stylesheets/ .. _sandbox: ../../../sandbox/ LaTeX preamble `````````````` Configuration by LaTeX code in the document preamble is also possible without a separate stylesheet. This way, packages can be loaded with options or commands re-defined without the need to create a separate file (new in Docutils 0.7). Option: latex-preamble_ Default: used for `font setup`_ Example: To use the better looking ``txtt`` font for monospaced text define the latex-preamble_ setting in a configuration file:: latex-preamble: \renewcommand{\ttdefault}{txtt} \usepackage{mathptmx} % Times \usepackage[scaled=.92]{helvet} % Helvetica .. _latex-preamble: config.html#latex-preamble .. _PDF standard fonts: https://en.wikipedia.org/wiki/PDF#Standard_Type_1_Fonts .. _Linux Libertine: http://www.linuxlibertine.org Templates ````````` Some customizations require commands at places other than the insertion point of stylesheets or depend on the deletion/replacement of parts of the document. This can be done via a custom template. See the `publisher documentation`_ for a description of the document parts available in a template file. Option: template_ In addition to the 'default.tex' template, the latex writer directory contains the alternatives 'titlepage.tex' (separate title page) and 'titlingpage.tex'" (separate title page with the `memoir`_ `document class`_). Example: Print a title page including docinfo, dedication, and abstract:: --template=titlepage.tex .. _publisher documentation: ../api/publisher.html .. _template: config.html#template-latex-writers Raw LaTeX ````````` By means of the `raw directive`_ or a derived `custom role`_, one can give commands directly to LaTeX. These can be both, styling as well as printing commands. Example: Math formula:: .. raw:: latex \[x^3 + 3x^2a + 3xa^2 + a^3,\] (Drawback: the formula will be invisible in other output formats. Better use the `math directive`_) Most LaTeX code examples also work as raw LaTeX inside the document. An exception are commands that need to be given in the document preamble (e.g. package loading with ``\usepackage``, which can be achieved with the ``--style-sheet`` or ``--latex-preamble`` command line options instead). Remember to use *re-defining* commands for customizing `Docutils specific LaTeX macros`_ with raw LaTeX. Example: Define the transition command as page break:: .. raw:: latex \renewcommand*{\DUtransition}{\pagebreak[4]} See also: * Defining a macro for a `custom role`_. * Forcing `page breaks`_. .. _raw directive: ../ref/rst/directives.html#raw .. _math directive: ../ref/rst/directives.html#math How to configure the ... ======================== admonitions ----------- Admonitions__ are specially marked "topics" that can appear anywhere an ordinary body element can. __ ../ref/rst/directives.html#admonitions Environment: ``DUadmonition`` (Command ``\DUadmonition`` with legacy-class-functions_.) Default: Typeset in a frame (90 % of text width). The admonition title is typeset with the ``\DUtitle`` command (see `titles`_). Example 1: A lighter layout without the frame:: \newenvironment{DUadmonition}% {\begin{quote}} {\end{quote}} Example 2: Print all admonitions in the margin:: \usepackage{environ} \NewEnviron{DUadmonition}{\marginpar{\BODY}} Example 3: Use the ``.. note::`` admonition for a margin note:: \usepackage{environ} \newcommand{\DUCLASSnote}{% \RenewEnviron{DUadmonition}{\marginpar{\BODY}}% \renewcommand{\DUtitle}[1]{}% suppress title ("Note") } .. caution:: Make sure there is enough space in the margin. ``\marginpar`` fails in some places or with some content. See also the environ_ and marginnote_ packages. .. _environ: https://ctan.org/pkg/environ .. _marginnote: https://ctan.org/pkg/marginnote .. _custom role: custom interpreted text roles ----------------------------- The rst `role directive`_ allows defining custom `text roles`_ that mark parts of inline text (spans) with class arguments (see section classes_). Commands: ``\DUrole``: dispatcher command ``\DUrole«classargument»``: optional styling command with 1 argument (the role content). Default: The default definition of ``\DUrole{«classargument»}{}`` calls the macro named ``\DUrole«classargument»{}`` if it is defined and silently ignores this class argument if not. Example 1: Typeset text in small caps:: .. role:: smallcaps :smallcaps:`Fourier` transformation This is transformed to the LaTeX code:: \DUrole{smallcaps}{Fourier} transformation The definition :: \newcommand{\DUrolesmallcaps}{\textsc} as `raw LaTeX`_ or in the custom `style sheet`_ will give the expected result (if the text font_ supports small caps). Example 2: Subscript text in normal size and *italic* shape:: .. role:: sub(subscript) As "sub" inherits from the standard "subscript" role, the LaTeX macro only needs to set the size and shape:: \newcommand{\DUrolesub}{\normalsize\itshape} Example 3: A role with several classes and a converted class name:: .. role:: custom4 :class: argI argII arg_3 is translated to the nested commands:: \DUrole{argi}{\DUrole{argii}{\DUrole{arg-3}{}}} With the definitions:: \newcommand{\DUroleargi}[1]{\textsc} \newcommand{\DUroleargii}[1]{{\large #1}} \makeatletter \@namedef{DUrolearg-3}{\textbf} \makeatother in a `style sheet`_\ [#]_ or as `raw LaTeX`_ in the document source, text styled with ``:custom4:`large bold small-caps``` will be typeset accordingly. .. [#] Leave out the ``\makeatletter`` - ``\makeatother`` pair if the style sheet is a LaTeX package (``*.sty``). .. _role directive: ../ref/rst/directives.html#role .. _text roles: ../ref/rst/roles.html .. _class directive: ../ref/rst/directives.html#class definition lists ---------------- ReStructuredText `definition lists`__ correspond to HTML ``
`` list objects. Environment: ``description``: LaTeX standard environment Command: ``\descriptionlabel``: styling macro for the description term Default: bold label text, hanging indent Example: A non-bold label can be achieved with:: \renewcommand\descriptionlabel[1]{\hspace\labelsep \normalfont #1} __ ../ref/rst/restructuredtext.html#definition-lists document class -------------- There are hundreds of LaTeX document classes installed by modern LaTeX distributions, provided by publishers, or available at CTAN_. Popular document classes: * article, report, book: standard document classes * scrartcl, scrrprt, scrbook: KOMA-script_ classes * memoir_: highly configurable class for larger documents Option: documentclass_ .. _KOMA-script: https://ctan.org/pkg/koma-script .. _memoir: https://ctan.org/pkg/memoir .. _documentclass: config.html#documentclass document info ------------- Content of the `bibliographic fields`__ at the top of a document. By default, docinfo items are typeset as a table. Options: use-latex-docinfo_, use-latex-abstract_ Length: ``\DUdocinfowidth``: the width for the `docinfo` table. Default: 90 % of text width: ``0.9\textwidth`` Example: set to 70 % of text width:: \newlength{\DUdocinfowidth} \setlength{\DUdocinfowidth}{0.7\textwidth} __ ../ref/rst/restructuredtext.html#bibliographic-fields .. _use-latex-docinfo: config.html#use-latex-docinfo .. _use-latex-abstract: config.html#use-latex-abstract document title -------------- A lone top-level section title is (usually) transformed to the document title (see `section structure`_). The format of the document title is defined by the `document class`_. The "article" document class uses an in-page title and the "report" and "book" classes write a separate title page. See the `TeX FAQ`_ on how to customize the `style of document titles`_. The default title page shows only title and subtitle, date and author are shown in the `document info`_ table. Options: use-latex-docinfo_ ``--template=titlepage.tex`` Put docinfo and abstract into the title page. A separate title page is used also with the "abstract" document class. .. _section structure: rst/quickref.html#section-structure .. _TeX FAQ: http://www.tex.ac.uk/faq .. _style of document titles: http://www.tex.ac.uk/cgi-bin/texfaq2html?label=titlsty field lists ----------- `Field lists`__ may be used as generic two-column table constructs in documents. Environment: ``DUfieldlist`` Default: Indented description list. Example: Use a description list customized with enumitem_:: \usepackage{enumitem} \newenvironment{DUfieldlist}% {\description[font=,style=sameline,leftmargin=8em]} {\enddescription} } The `KOMA-script`_ classes provide a similar environment under the name `labeling`. .. _enumitem: https://ctan.org/pkg/enumitem __ ../ref/rst/restructuredtext.html#field-lists figure and table captions ------------------------- The caption_ package provides many ways to customise the captions in floating environments like figure and table. The chngcntr_ package helps to configure the numbering of figure and table caption numberings. Some document classes (e.g. KOMA-script_) provide additional configuration. Also see the related `LaTeX FAQ entry`__ Example :: \usepackage{caption} \captionsetup{justification=raggedleft,singlelinecheck=false} .. _caption: https://ctan.org/pkg/caption .. _chngcntr: https://ctan.org/pkg/chngcntr __ http://www.tex.ac.uk/cgi-bin/texfaq2html?label=running-nos figure placement ---------------- Figures_ might be typeset at the place of definition (default) or "float" to a suitable place at the top or bottom of a page. This is implemented using the float_ package. Command: ``\floatplacement`` The placement setting is valid from the point of definition until the next ``\floatplacement`` command or the end of the document. See float.pdf_ for details. Default: ``\floatplacement{figure}{H}`` (here definitely). This corresponds most closely to the source and HTML placement (principle of least surprise). Example 1: In a custom `style sheet`_, set the default to let LaTeX find a suitable place for figure floats:: \usepackage{float} \floatplacement{figure}{htbp} % here, top, bottom, extra-page Example 2: To move all following figures to the top or bottom of the page write in the document source:: .. raw:: latex \floatplacement{figure}{tb} .. _figures: ../ref/rst/directives.html#figure .. _float: https://ctan.org/pkg/float .. _float.pdf: https://mirrors.ctan.org/macros/latex/contrib/float/float.pdf .. _font setup: font ---- The selected text font influences the *look*, the *feel*, and the *readability* of the document (cf. http://www.csarven.ca/web-typography). Selecting a suitable font also solves the problem with `bad looking PDF output`_. Font selection is one of the main differences between LaTeX and XeTeX/LuaTeX: LaTeX cannot use the fonts of the operating system directly but needs specially installed fonts with additional supporting files. XeTeX/LuaTeX can use system fonts and provides access to the full feature set of modern OpenType_ fonts. .. _OpenType: https://en.wikipedia.org/wiki/OpenType The default font setup is done in the latex-preamble_: LaTeX `PDF standard fonts`_ (Times, Helvetica, Courier) XeTeX/LuaTeX `Linux Libertine`_, a free, high quality alternative to Times with a wide coverage of glyphs, styles, and OpenType features. Despite its name, Linux Libertine can be used on any operating system that can handle OpenType fonts. Alternative fonts can be selected by LaTeX a) specifying the corresponding LaTeX package(s) as argument to the stylesheet_ option_ or with the ``\usepackage`` LaTeX command. * packages can be combined, * passing options to a package is only possible in a `style sheet`_ or the `LaTeX preamble`_. b) changing the font-default macros ``\rmdefault``, ``\sfdefault`` and/or ``\ttdefault`` in a custom `style sheet`_, the `LaTeX preamble`_ or `raw LaTeX`_. Example 1: Use `Latin Modern`_. `LaTeX code`_:: \usepackage{lmodern} Command line argument:: --stylesheet=lmodern Example 2: The _`Times/Helvetica/Courier` `PDF standard fonts`_ are selected by the LaTeX code [#]_:: \usepackage{mathptmx} % Times for serif and math \usepackage[scaled=.90]{helvet} % downscaled Helvetica for sans serif \usepackage{courier} % Courier for teletype (mono-space) Since Docutils 0.7, this is the default value of the `latex-preamble`_ option. .. [#] When generating PDF-files from LaTeX, the `PDF standard fonts`_ do not need to be embedded in the document. While this results in smaller files, the actually used fonts on screen and in print might differ! (For details see, e.g., the testflow_ package documentation.) Example 3: Use the teletype font from the txfonts_ package. As there is no package for this, we re-define the font macro with the `LaTeX code`_:: \renewcommand{\ttdefault}{txtt} XeTeX/LuaTeX using the macros of the fontspec_ package. Use some font-viewer or -manager (e.g. fontmatrix_) to find out the correct names of the fonts on your system. Example: DejaVu_, very wide coverage, screen optimized. As this font runs wide, add ``DIV=10`` to the `documentoptions`_:: \setmainfont{DejaVu Serif} \setsansfont{DejaVu Sans} \setmonofont[HyphenChar=None]{DejaVu Sans Mono} .. _fontspec: https://ctan.org/pkg/fontspec .. _fontmatrix: http://fontmatrix.net/ .. _DejaVu: http://dejavu-fonts.org/ .. _documentoptions: config.html#documentoptions choice of suitable fonts ```````````````````````` High quality free fonts suitable for use with XeTeX/LuaTeX are, e.g., listed at `Good Libre Fonts`_, `25 Best Free Quality Fonts`_ and the update `19 More Free Quality Fonts`_. The `LaTeX Font Catalogue`_ provides information and examples for a wide range of fonts available for use with LaTeX. Here is just a selection: a) The `Latin Modern`_ (LM) fonts are extended outline versions of the standard TeX font Computer Modern (CM). +1 simple invocation: ``--stylesheet=lmodern`` +1 keeps the traditional TeX "look and feel": +1 generally accepted as high quality CM replacement, +1 comprehensive math support, +1 including optical sizes, +1 compatible with extensions made to match CM, -1 modern types are hard to read at low (screen) resolutions. -1 not part of a minimal standard TeX installation b) CM-Super_ is another outline CM replacement. +1 simple invocation: modern LaTeX distributions use CM-Super automatically instead of CM if it is installed. -1 said to be of inferior quality compared to LM. -1 not part of a minimal standard TeX installation, bigger download size than Latin Modern (64 MB). c) `Bera`_ (Bitstream Vera) +1 simple invocation: ``--stylesheet=bera`` +1 optimized for on-screen viewing with goot hinting -1 not part of a minimal standard TeX installation d) PSNFSS_ Postscript fonts +1 part of every standard TeX installation +1 smaller PDF/Postscript document size if standard fonts are not embedded -1 restricted set of glyphs in the free versions [#]_ -1 different fonts for roman, sans-serif and typewriter fonts. -1 invocation somewhat more complex, as several packages are required for a complete font set, sometimes including package options. Roman (serif) PSNFSS fonts: Bookman good legibility but very wide. Charter bread-and-butter type optimized for printing on low-resolution printers New Century Schoolbook good legibility but very wide. Palatino +1 recommended by font experts +1 good LaTeX support including matching math fonts, small caps, old-style figures -1 bad rendering in xpdf viewer (auto-hinting leads to different x-hight for different characters at some magnifications) (this is fixed in recent versions). Times +1 the serif `PDF Standard Font`_, -1 overused and quite narrow (devised for multi-column layouts). Utopia recommended by font experts .. table:: Font packages for standard Postscript fonts (cf. `Using common Postscript fonts with LaTeX`_) ========= ============ ============= ============= ========= Package Roman Sans Serif Typewriter Math ========= ============ ============= ============= ========= (none) CM Roman CM Sans Serif CM Typewriter CM Math mathpazo Palatino Palatino mathptmx Times Times helvet Helvetica avant Avant Garde courier Courier chancery Zapf Chancery bookman Bookman Avant Garde Courier newcent New Century Avant Garde Courier Schoolbook charter Charter utopia Utopia fourier Utopia Fourier ========= ============ ============= ============= ========= .. [#] Extended versions of the standard Postscript fonts including accented chars, as well as real small-caps and old-style numbers are available with the `TeX Gyre`_ bundle which is part of, e.g., `TeX Live`_. .. _LaTeX Font Catalogue: http://www.tug.dk/FontCatalogue/ .. _Latin Modern: https://ctan.org/pkg/lm .. _CM-Super: https://ctan.org/pkg/cm-super .. _bera: https://ctan.org/pkg/bera .. _TeX Gyre: http://www.gust.org.pl/projects/e-foundry/tex-gyre .. _PSNFSS: https://ctan.org/pkg/psnfss .. _Using common PostScript fonts with LaTeX: https://mirrors.ctan.org/macros/latex/required/psnfss/psnfss2e.pdf .. _TeX Live: http://tug.org/texlive/ .. _txfonts: https://ctan.org/pkg/txfonts .. _PDF Standard Font: https://en.wikipedia.org/wiki/PDF#Standard_Type_1_Fonts .. _testflow: http://www.tex.ac.uk/tex-archive/help/Catalogue/entries/testflow.html .. _Good Libre Fonts: http://typophile.com/node/18207 .. _25 Best Free Quality Fonts: http://www.alvit.de/blog/article/20-best-license-free-official-fonts .. _19 More Free Quality Fonts: http://www.smashingmagazine.com/2006/10/11/17-more-free-quality-fonts/ font encoding ------------- LaTeX font encodings are described in detail in the encguide_ which is part of the LaTeX base documentation. Option: font-encoding_ Default: "T1" Example 1: Use the (obsolete) LaTeX default encoding "OT1":: --font-encoding=OT1 or (without loading the fontenc_ package):: --font-encoding="" This will improve the look on screen with the default Computer Modern fonts at the expense of problems with `search and text extraction`_ The recommended way is to select a T1-encoded "Type 1" (vector) font, for example `Latin Modern`_ Example 2: Support for characters in the Unicode blocks Latin, Latin-1 Supplement, and Greek together with a T1-encoded "Type 1" (vector) font, for example `Latin Modern`_:: --font-encoding=LGR,T1 --stylesheet=lmodern .. _encguide: https://mirrors.ctan.org/macros/latex/base/encguide.pdf .. _font-encoding: config.html#font-encoding .. _fontenc: https://ctan.org/pkg/fontenc font size --------- Add font size in points to the document options, e.g. ``--documentoptions=12``, use e.g. the document classes provided by extsizes_ for values other than [10,11,12]. .. _extsizes: https://ctan.org/pkg/extsizes footnotes --------- By default, footnotes are set with Docutils-specific wrappers around the standard ``\footnotemark`` and ``\footnotetext`` commands. You can configure the footnote layout similar to standard LaTeX footnotes in a custom `style sheet`_ or the `LaTeX preamble`_. Further configuration is possible by alternative definitions of ``\DUfootnotemark`` and ``\DUfootnotetext`` Example 1: Set footnote text with a hanging indent. * This is the default with KOMA-script_ classes, e.g:: --documentclass=scrartcl (for further configuration, see the `KOMA-script Guide`_), * with package footmisc_:: \usepackage[hang]{footmisc} \setlength{\footnotemargin}{0em} (play with the ``\footnotemargin`` setting), * redefine ``\DUfootnotetext`` inserting `\hangindent`:: \newcommand{\DUfootnotetext}[4]{% \begingroup% \renewcommand{\thefootnote}{% \protect\raisebox{1em}{\protect\hypertarget{#1}{}}% \protect\hyperlink{#2}{#3}}% \footnotetext{\hangindent=2em #4}% \endgroup% } (adapt the ``\hangindent`` value). Example 2: Footnote marks in normal font size, not superscript:: \usepackage{scrextend} % not required with KOMA-script document classes \deffootnote{1em}{1em}{\thefootnotemark\ } (See the `KOMA-script Guide`_ for details and other options.) Example 3: Place the footnote text where it appears in the source document (instead of at the page bottom). This can be used to get the effect of endnotes (needs the hanging_ package):: \usepackage{hanging} \newcommand{\DUfootnotetext}[4]{% \par\noindent\raisebox{1em}{\hypertarget{#1}{}}% \hyperlink{#2}{#3}% \hangpara{\parindent}{1}#4% } .. _footmisc: https://ctan.org/pkg/footmisc .. _hanging: https://ctan.org/pkg/hanging hyphenation ----------- The amount of hyphenation is influenced by ``\hyphenpenalty``, setting it to 10000 almost prevents hyphenation. As this produces lines with more space between words one should increase Latex's ``\tolerance`` for this. Example: :: \hyphenpenalty=5000 \tolerance=1000 hyperlinks ---------- Options: hyperlink-color_, hyperref-options_ Hyperlinks are realized using the hyperref_ package. As it re-defines many standard LaTeX macros, this package is loaded last, *after* the style sheets. However, you can load hyperref before a package that requires its presence in a `style sheet`_ or the `LaTeX preamble`_ (see example below). This will ignore options set with hyperlink-color_ and hyperref-options_. URLs are typeset with the "url" package (loaded implicitly by "hyperref"). The font of URLs can be defined with the ``\urlstyle`` command. Valid arguments are :same: normal text font, Docutils default, :tt: teletype (monospaced), LaTeX default, :rm: roman, :sf: sans serif Example: Custom loading of the hyperref package also switches to the LaTeX default (monospaced fonts for URLs). Reset to use the text font:: \usepackage[unicode,colorlinks=true,linkcolor=green]{hyperref} \urlstyle{same} See also `non-breaking hyperlinks`_. .. _hyperlink-color: config.html#hyperlink-color .. _hyperref-options: config.html#hyperref-options disable hyperlinks `````````````````` To suppress the hyper-linking completely (e.g. for printing or to avoid clashes with other packages), set hyperref-options_ to "draft" or load the "nohyperref" package that comes with the "hyperref" bundle. Option: ``--hyperref-options=draft`` `LaTeX code`_:: \usepackage{nohyperref,url} \urlstyle{same} .. _hyperref: https://ctan.org/pkg/hyperref language -------- The global document language can be set with the language-code_ configuration setting. The language of text parts can be set adding the language tag prefixed by "language-" to an element's classes_ attribute, e.g. ``language-el`` for a Greek text part. .. _language-code: config.html#language-code line blocks ----------- In `line blocks`__, newlines and leading whitespace are respected. Environment: ``DUlineblock``: special list environment for line blocks Length: ``\DUlineblockindent``: indentation of indented lineblock parts. Default: 2.5 times the font height: ``2.5em`` Example: set to the paragraph indentation:: \newlength{\DUlineblockindent} \setlength{\DUlineblockindent}{\parindent} __ ../ref/rst/restructuredtext.html#line-blocks line spacing ------------ Commands: ``\linespread``: for small adjustments ``\singlespacing``, ``\onehalfspacing``, and ``\doublespacing``: from package `setspace` Example 1: Get document wide double spacing:: \usepackage{setspace} \doublespacing Example 2: Increase line spacing by five percent for better readability:: \linespread{1.05} literal blocks -------------- No markup processing is done within a `literal block`__. It is left as-is, and is typically rendered in a monospaced typeface Option: literal-block-env_ Example: ``--literal-block-env=lstlisting`` The ``lstlisting`` environment is highly configurable (as documented in listings.pdf_) and provides syntax highlight for many programming languages, for instance :: \renewcommand{\ttdefault}{txtt} \lstset{language=Python, morekeywords=[1]{yield}} \lstloadlanguages{Python} \lstset{ basicstyle=\ttfamily, keywordstyle=\bfseries, commentstyle=\rmfamily\itshape, stringstyle=\slshape, } \lstset{showstringspaces=false} \lstset{columns=fullflexible, basewidth={0.5em,0.4em}} and to get LaTeX syntax highlight for a code block with "listings":: \lstloadlanguages{[LaTeX]TeX} % comma separated list of languages \newcommand{\DUCLASSlatex}{\lstset{language=[LaTeX]TeX}} The indentation of literal blocks can be reset with :: \lstset{resetmargins=true} and/or configured with e. g.:: \lstset{xleftmargin=-2em} __ ../ref/rst/restructuredtext.html#literal-blocks .. _literal-block-env: config.html#literal-block-env .. _listings.pdf: https://mirrors.ctan.org/macros/latex/contrib/listings/listings.pdf lists ----- Remove extra vertical whitespace between items of bullet lists and enumerated lists. Example: Pass the class argument "compact" to the list:: .. class:: compact * first item * second item The following lines for the `LaTeX preamble`_ use the enumitem_ package to remove spacing from all lists with class argument "compact":: \usepackage{enumitem} \newcommand*{\DUCLASScompact}{\setlist{noitemsep}} list of figures/tables ---------------------- Docutils does not support lists of figures or tables. However, with LaTeX, they can be generated using `raw LaTeX`_ in the document source. Commands: ``\listoffigures``: a list of figures ``\listoftables``: a list of tables Example: :: .. raw:: latex \listoffigures option list ----------- `Option lists`__ are two-column lists of command-line options and descriptions, documenting a program's options. Environment: ``DUoptionlist``: environment for option lists, Command: ``\DUoptionlistlabel``: set appearance of the options Example: set command options with a bold monospace font:: \newcommand{\DUoptionlistlabel}{\texttt{\textbf{#1}} \hfill} __ ../ref/rst/restructuredtext.html#option-lists page breaks ----------- * Page breaks before top-level sections are the default with a documentclass that provides "chapters", e.g. "book", "memoir" or "scrbook". * Redefining the \section or \section* command in a style sheet is possible too. * `Raw LaTeX`_ or a `custom role`_ can be used. * The transition element can be re-defined to produce a page break, Commands ``\newpage``: hard pagebreak at exactly this position ``\pagebreak[2]``: recommended page break after line end (precedence 1...4) Example: Define the transition command as page break with the `LaTeX code`_:: \newcommand*{\DUtransition}{\pagebreak[4]} (use ``\renewcommand`` with `raw LaTeX`_). page layout ----------- By default, paper size and margin settings are determined by the document class. The following packages help to configure the page layout: a) The `typearea`_ package (part of the `KOMA-script`_ bundle) calculates a *good* page layout (based on rules and recommendations of typography experts). See the `KOMA-Script Guide`_ for details on what is a *good* layout and how this is achieved. b) The `geometry`_ package is recommended if you have to follow guidelines with fixed values for the margins. For details see the `geometry manual`_. Example 1: Let `typearea` determine the type area with ``DIV=calc`` in the documentoptions:: --documentoptions='a4paper,DIV=calc' The ``DIV`` option can also be specified, like ``DIV=10``. It defines how "crowded" a page will be: larger values mean larger text area (at the expense of readability). Example 2: `LaTeX code`_ to set margins with the geometry_ package:: \usepackage{geometry} \geometry{hmargin={3cm,0.8in},height=8in} \geometry{height=10in}. .. _typearea: https://ctan.org/pkg/typearea .. _geometry: https://ctan.org/pkg/geometry .. _KOMA-Script Guide: https://mirrors.ctan.org/macros/latex/contrib/koma-script/doc/scrguien.pdf .. _geometry manual: https://mirrors.ctan.org/macros/latex/contrib/geometry/geometry.pdf page headers and footers ------------------------ With the fancyhdr_ package or the `KOMA-script`_ classes, you can define custom page head- and foot-lines. The `"header" and "footer" directives`_ save their content in the macros ``\DUheader`` rsp. ``\DUfooter``. The macros can be used in LaTeX code and will be replaced by LaTeX with the content of the directives. Example: `LaTeX code`_ to place left-aligned "header" and "footer" on every page with fancyhdr_:: \usepackage{fancyhdr} \fancyhead[L]{\DUheader} \fancyfoot{} % reset \fancyfoot[L]{\DUfooter} \pagestyle{fancy} .. _fancyhdr: http://www.ctan.org/pkg/fancyhdr .. _"header" and "footer" directives: ../ref/rst/directives.html#header page numbering -------------- Example: Number pages by chapter (using the chappg_ package):: \usepackage{chappg} See the `chappg documentation`_ for details. .. _chappg: https://ctan.org/pkg/chappg .. _chappg documentation: https://mirrors.ctan.org/macros/latex/contrib/chappg/chappg.pdf paper size ---------- Paper geometry can be changed using ``--documentoptions`` or with the `geometry`_ package. `LaTeX code`_:: \usepackage{geometry} \geometry{OPTIONLIST} Default: a4paper Some possibilities: * a4paper, b3paper, letterpaper, executivepaper, legalpaper * landscape, portrait, twoside. Example: Choose A5 pager in landscape orientation with command line argument:: --documentoptions=a5paper,landscape The same with LaTeX commands in the `style sheet`_:: \usepackage{geometry} \geometry{a5paper,landscape} For details see the `geometry manual`_. paragraph indent ---------------- Default (in most document classes): Indent the first line in a paragraph unless it is the first line of a chapter, section, subsection, or subsubsection. Example 1: To set paragraph indentation to zero but add a vertical space between load the `parskip` package with the command line argument:: --stylesheet=parskip or in a custom `style sheet`_ with:: \usepackage{parskip} Example 2: To suppress the indentation of a specific paragraph, you may give it the class "noindent" with, e.g. :: .. class:: noindent This paragraph should not be indented. and define the `custom role`_ command:: \newcommand{\DUrolenoindent}[1]{\noindent #1} rubric ------ A rubric__ is like an informal heading that doesn't correspond to the document's structure. Command: ``\DUrubric`` Default: subsubsection style (unnumbered), italic Example1: Set centred and red:: \newcommand*{\DUrubric}[1]{% \subsubsection*{\centerline{\color{red}#1}}} .. note:: Class attribute values are ignored because the "classes_ wrapper" interferes with LaTeX's formatting (spacing/indentation) of text following a section heading. Consider using a `topic element`_ or a container_. __ ../ref/rst/directives.html#rubric .. _container: ../ref/rst/directives.html#container section headings ---------------- Options: documentclass_, use-part-section_ Section headings are converted into LaTeX macros according to their level, the document class and the value of the use-part-section_ setting: ===== ============= ================== ============= ============== Level article article with part book [#]_ book with part ===== ============= ================== ============= ============== 1 section part chapter part 2 subsection section section chapter 3 subsubsection subsection subsection section 4 paragraph subsubsection subsubsection subsection 5 subparagraph paragraph paragraph subsubsection 6 DUtitle subparagraph subparagraph paragraph 7 DUtitle DUtitle DUtitle subparagraph ===== ============= ================== ============= ============== .. [#] One of the document classes 'book', 'memoir', 'report 'scrbook', or 'scrreprt'. .. _use-part-section: config.html#use-part-section section numbering ----------------- Sections are numbered if there is a `sectnum directive`_ in the document. Option: sectnum_xform_ ``--section-numbering``, ``--no-section-numbering`` If sectnum_xform_ is False, section numbers are generated by LaTeX. In this case the "prefix" and "suffix" arguments of the `sectnum directive`_ are ignored. The section number style is determined by the `document class`_ and can be configured in a LaTeX `style sheet`_, e.g.:: \setcounter{secnumdepth}{5} .. note:: The LaTeX name is 'secnumdepth' (without 't'). .. _sectnum directive: ../ref/rst/directives.html#sectnum .. _sectnum_xform: config.html#sectnum-xform sidebar ------- Sidebars__ are like miniature, parallel documents that occur inside other documents, providing related or reference material. They can be likened to super-footnotes; their content is outside of the flow of the document's main text. Command: ``DUsidebar`` Default: Box with grey background. Example: Use margin notes:: \newcommand{\DUsidebar}[1]{\marginpar{\flushleft #1}} * Make sure the margin is wide enough to hold the note. * This fails with some constructs inside the `side bar` and where \marginpar cannot be used, e.g., inside floats, footnotes, or in frames made with the framed package (see marginnote_). __ https://docutils.sourceforge.io/docutils/docs/ref/rst/directives.html#sidebar size of a pixel --------------- The *physical size* of a pixel depends on the resolution of the output device and is usually specified in *dots per inch* (DPI). The *length unit* "px" is defined by the output format. For LaTeX, it is `defined in pdfTeX and LuaTeX`__ (the `xetex` writer emulates this definition). Default: 72 DPI, i.e. 1 px = 1/72 in. [#]_ Example: Set the value to match the CSS definition with the `LaTeX code`_:: \pdfpxdimen=1in \divide\pdfpxdimen by 96 % 1/96 inch .. [#] The `CSS length unit ``px```_ defaults to 1/96 inch. __ https://tex.stackexchange.com/questions/41370/ what-are-the-possible-dimensions-sizes-units-latex-understands .. _CSS length unit ``px``: https://www.w3.org/TR/css-values-3/#px .. _reference pixel: https://www.w3.org/TR/css-values-3/#reference-pixel table style ------------ A pre-configured *table style* can be globally selected via the table_style_ setting or set for individual tables via a `class directive`_ or the class option of the `table directive`_. Supported values: standard Borders around all cells. booktabs A line above and below the table and one after the head. borderless No borders. colwidths-auto Column width determination by LaTeX. Overridden by the `table directive`_'s "widths" option. .. warning:: ``colwidths-auto`` is only suited for tables with simple cell content. LaTeX puts the content of auto-sized columns on one line (merging paragraphs) and may fail with complex content. .. eventually in future align-left, align-center, align-right Align tables. By default, *column widths* are computed from the source column widths. The `legacy_column_widths`_ setting selects the conversion algorithm. Custom column widths can be set with the "widths" option of the `table directive`_. See also the section on problems with tables_ below. .. _new_column_widths: .. _legacy_column_widths: config.html#legacy-column-widths .. _table_style: config.html#table-style-latex-writers .. _"widths" option: .. _table directive: ../ref/rst/directives.html#table table of contents ----------------- A `contents directive`_ is replaced by a table of contents (ToC). Option: use-latex-toc_ ``--use-latex-toc``, ``--use-docutils-toc`` With use-latex-toc (default since release 0.6): * The ToC is generated by LaTeX (via the ``\tableofcontents`` command). The layout depends on the chosen document class and can be configured in a custom `style sheet`_ (see e.g. the `KOMA-Script Guide`_ for the `KOMA-script`_ classes). * The depth of the ToC and PDF-bookmarks can be configured + with the "depth" argument of the `contents directive`_, or + in a style sheet with e.g. ``\setcounter{tocdepth}{5}``. * Local ToCs are done with the minitoc_ package. See the `minitoc documentation`_ for the numerous configuration options. .. note:: Minitoc supports local ToCs only at "part" and top section level ("chapter" or "section"). Local `contents` directives at lower levels are ignored (a warning is issued). This is an intended feature of the minitoc_ package. If you really require local ToCs at lower level, turn off the use-latex-toc_ option. .. _use-latex-toc: config.html#use-latex-toc .. _contents directive: ../ref/rst/directives.html#contents .. _minitoc: https://ctan.org/pkg/minitoc .. _minitoc documentation: https://mirrors.ctan.org/macros/latex/contrib/minitoc/minitoc.pdf title reference role -------------------- `Title reference`_ is the default `default role`_ for `interpreted text`_. Command: ``\DUroletitlereference`` Default: use slanted font (``\textsl``) Example: set title references with a bold monospace font:: \newcommand{\DUroletitlereference}[1]{\texttt{\textbf{#1}}} .. _title reference: ../ref/rst/roles.html#title-reference .. _default role: ../ref/rst/directives.html#setting-the-default-interpreted-text-role .. _interpreted text: ../ref/rst/restructuredtext.html#interpreted-text titles ------ The titles of admonitions_, sidebar_, and `topic element`_ use the ``\DUtitle`` command. Example 1: a centered and somewhat larger title for topcis:: \newcommand*{\DUCLASStopic}{ \renewcommand*{\DUtitle}[1]{\subsection*{\centering #1} } Example 2: a right-pointing hand as title for the "attention" directive:: \usepackage{pifont} \newcommand*{\DUCLASSattention}{ \renewcommand*{\DUtitle}[1]{\ding{43}} } The title argument is "swallowed" by the command. To have both, hand and title use:: \usepackage{pifont} \newcommand*{\DUCLASSattention}{ \newcommand*{\DUtitle}[1]{\ding{43} #1} } text encoding ------------- The encoding of the LaTeX source file is Docutils' *output* encoding but LaTeX' *input* encoding. Option: output-encoding_ ``--output-encoding=OUTPUT-ENCODING`` Default: "utf-8" Example: Encode the LaTeX source file with the ISO `latin-1` (west european) 8-bit encoding (the default in Docutils versions up to 0.6.):: --output-encoding=latin-1 Note: 8-bit LaTeX comes with two options for UTF-8 support, :utf8: by the standard `inputenc`_ package with only limited coverage (mainly accented characters). :utf8x: supported by the `ucs`_ package covers a wider range of Unicode characters than does "utf8". It is, however, a non-standard extension and no longer developed. Currently, the "latex2e" writer inserts ``\usepackage[utf8]{inputenc}`` into the LaTeX source if it is UTF-8 encoded. .. with utf8x: If LaTeX issues a Warning about unloaded/unknown characters adding :: \PreloadUnicodePage{n} (where *n* is the Unicode page-number) to the style sheet might help. .. _LaTeX Unicode: http://www.unruh.de/DniQ/latex/unicode/ .. _output-encoding: config.html#output-encoding .. _inputenc: https://ctan.org/pkg/inputenc .. _ucs: https://ctan.org/pkg/unicode topic element ------------- A topic_ is like a block quote with a title, or a self-contained section with no subsections. Topics and rubrics can be used at places where a `section title`_ is not allowed (e.g. inside a directive). Example: Use a standard paragraph for a topic:: \newcommand{\DUCLASStopic}{% \renewenvironment{quote}{}{}% } .. _topic: ../ref/rst/directives.html#topic .. _section title: ../ref/rst/restructuredtext.html#sections transition element ------------------ Transitions__ are commonly seen in novels and short fiction, as a gap spanning one or more lines, marking text divisions or signaling changes in subject, time, point of view, or emphasis. Command: ``\DUtransition`` Default: A horizontal line, 1/3 of text width Example 1: Use three stars:: \newcommand*{\DUtransition}{\centering{}*\quad*\quad*} Alternatively use the more elaborated version in `transition-stars.sty`_. Example 2: If paragraphs are separated by indentation, you can simply use a vertical space:: \newcommand*{\DUtransition}{\vspace{2ex}} __ https://docutils.sourceforge.io/docutils/docs/ref/rst/restructuredtext.html#transitions .. _transition-stars.sty: ../../../sandbox/stylesheets/transition-stars.sty Changes ======= * The Docutils HISTORY_ lists all changes during the history of docutils. Important changes are summarized in the RELEASE-NOTES_. .. _HISTORY: ../../HISTORY.html .. _RELEASE-NOTES: ../../RELEASE-NOTES.html Problems ======== Troubleshooting --------------- Bad looking PDF output `````````````````````` What I am looking for when I try Docutils is if the PDF files I can get are of high quality. Unfortunately that never is the case. So am I just stupid or is there a way to get really high quality pdf from Docutils? Make sure the default font is not a bitmap font. There is `Latin Modern`_ if you like the look of the standard font on paper, but want nice pdf. Or select something else like Times, Palatino, ... via configuration `options/settings`_. See font_ and font-encoding_. footnote mark and text at different pages ````````````````````````````````````````` Docutils stores the footnote text in a separate node, at the position where it is specified in the input document. With the default settings, the footnote is put at the bottom of the page where the footnote text is located, maybe far away from the footnote mark (see e.g. ``_). To get footnote mark and text at the same page, keep footnote mark and footnote text close together. non-breaking hyperlinks ``````````````````````` If you convert with ``latex`` (as opposed to ``pdflatex``), hyperlinks will not wrap and sometimes stick into the margin. Wrong: :: \usepackage[breaklinks=true]{hyperref} "breaklinks" is an internal option that indicates whether the chosen driver can handle split links. (It might work to *disable* link breaking.) Right: Use one of the following: a) compile with pdflatex_, b) use the package breakurl_, c) (for printout) `disable hyperlinks`_ using the package "nohyperref". See also the `Link text doesn’t break at end line`_ LaTeX FAQ entry. .. _breakurl: https://ctan.org/pkg/breakurl .. _Link text doesn’t break at end line: http://www.tex.ac.uk/cgi-bin/texfaq2html?label=breaklinks Glyph not defined in PD1 encoding ````````````````````````````````` If a section title or other link contains non-Latin (e.g. Cyrillic) characters, the LaTeX log contains lots of warnings like:: Package hyperref Warning: Glyph not defined in PD1 encoding, (hyperref) removing `\CYRZ' on input line 6. ... This can be solved with the "unicode" hyperref_option_ setting:: --hyperref-option=unicode (works also with non-unicode input/output encoding (e.g. "koi8r" or "latin1"). Newer versions of hyperref default to "unicode=true". .. _hyperref_option: config.html#stylesheet-latex-writers image inclusion ``````````````` Images__ are included in LaTeX with the help of the `graphicx` package. The supported file formats depend on the used driver: * pdflatex_, lualatex, and xelatex_ work with PNG, JPG, or PDF, but **not EPS**. * Standard latex_ can include **only EPS** graphics, no other format. * latex + dvipdfmx works with EPS and JPG (add 'dvipdfmx' to the documentoptions_ or graphicx-option_ setting and 'bmpsize' to the stylesheet_ setting). If PDF-image inclusion in PDF files fails, specifying ``--graphicx-option=pdftex`` might help. For details see grfguide.pdf_. The Rubber_ wrapper can be used for automatic image conversion. Docutils expects an URI as pointer to the image file. The latex writer transforms this URI to a local path. By default, LaTeX does not accept spaces and more than one dot in the filename. If using "traditional" filenames is not an option, adding grffile_ to the `style sheets`_ can help. __ ../ref/rst/directives.html#images .. _grfguide.pdf: https://mirrors.ctan.org/macros/latex/required/graphics/grfguide.pdf .. _grffile: https://ctan.org/pkg/grffile .. _graphicx-option: config.html#graphicx-option Why are my images too big? `````````````````````````` HTML-browsers use the actual screen resolution (usually around 100 DPI). The CSS specification suggests: It is recommended that the reference pixel be the visual angle of one pixel on a device with a pixel density of 96 DPI and a distance from the reader of an arm's length. -- https://www.w3.org/TR/CSS2/syndata.html#length-units This is why pixmap images without size specification or objects with a size specified in ``px`` tend to come too large in the PDF. Solution: Specify the image size in fixed units (``pt``, ``cm``, ``in``) or configure the `size of a pixel`_ (length unit px). Error ``illegal unit px`` ````````````````````````` If you convert the LaTeX source with a legacy program, you might get this error. The unit "px" was introduced by the `pdfTeX` converter on 2005-02-04. `pdfTeX` is used also for conversion into DVI format in all modern LaTeX distributions (since ca. 2006). If updating LaTeX is not an option, just remove the "px" from the length specification. HTML/CSS will default to "px" while the `latexe2` writer will add the fallback unit "bp". Error ``Symbol \textcurrency not provided`` ... ``````````````````````````````````````````````` The currency sign (\\u00a4) is not supported by all fonts (some have an Euro sign at its place). You might see an error like:: ! Package textcomp Error: Symbol \textcurrency not provided by (textcomp) font family ptm in TS1 encoding. (textcomp) Default family used instead. (which in case of font family "ptm" is a false positive). Add either :warn: turn the error in a warning, use the default symbol (bitmap), or :force,almostfull: use the symbol provided by the font at the users risk, to the document options or use a different font package. Warning: language … not supported ````````````````````````````````` The "latex" writer uses the LaTeX package Babel_ and the "xetex" writer uses Polyglossia_ for language_ support (hyphenation rules, auto-text localisations and typographic rules). Polyglossia_ supports more languages, so switching to the "xetex_" writer may help. For short quotes or if language support is provided by the user via other `LaTeX document classes and packages`_, the warning can be ignored. .. _Babel: https://ctan.org/pkg/babel .. _Polyglossia: https://ctan.org/pkg/polyglossia Search and text extraction `````````````````````````` Search for text that contains characters outside the ASCII range might fail. See font_ and `font encoding`_ (as well as `Searching PDF files`_ for background information).

With "traditional" TeX engines (e.g. pdflatex_): - Generate LaTeX code with `output-encoding`_ "utf-8". - Add the pmboxdraw_ package to the `style sheets`_. (For shaded boxes also add the `color` package.) Unfortunately, this defines only a subset of the characters (see pmboxdraw.pdf_ for a list). .. _pmboxdraw: https://ctan.org/pkg/pmboxdraw .. _pmboxdraw.pdf: https://mirrors.ctan.org/macros/latex/contrib/pmboxdraw/pmboxdraw.pdf Bugs and open issues -------------------- Open to be fixed or open to discussion.

Later the `figure` directive was added that puts images into figure floats. This results in footnotes, citations, and figures possibly being mixed at page foot. Workaround: Select citation handling with the use_latex_citations_ option. If ``use-latex-citations`` is used, a bibliography is inserted right at the end of the document. *This should be customizable*. If ``use-latex-citations`` is used adjacent citation references (separated only by a single space or a newline) are combined to a single citation group, i.e. ``[cite1]_ [cite2]_`` results in ``\cite{cite1,cite2}``. The appearance in the output can be configured in a `style sheet`_. .. _use_latex_citations: config.html#use-latex-citations Tables `````` * Too wide tables (cf. `bug #422`_): Try the new_column_widths_ algorithm or use the `"widths" option`_ to manually set the table column widths. * Table cells with both multirow and multicolumn are currently not possible. .. _bug #422: https://sourceforge.net/p/docutils/bugs/422/ Figures ``````` * Figures are always as wide as the containing text. The "figwidth" argument is currently not supported. As a consequence, the "align" argument has no effect. * Wrapping text around figures is currently not supported. (Requires the `wrapfig`_ package.) .. _wrapfig: https://ctan.org/pkg/wrapfig Miscellaneous ````````````` * Pdfbookmark level 4 (and greater) does not work (might be settable but complicated). * Hyperlinks are not hyphenated; this leads to bad spacing.
