• Difference between \begin{align*}...\end{align*} and \align* ...\endalign*
    by user2026844 on December 10, 2025 at 10:46 pm

    I thought that \begin{env}...\end{env} is essentially equivalent to \env ...\endenv. However, in the case of align*, the first example below compiles without issue, while the second gives a runaway argument. (It does work with equation* though...) Why? \documentclass{article} \usepackage{amsmath} \begin{document} % no issue %\begin{align*} %x & = 1 \\ %y & = 2 \\ %\end{align*} % runaway arg \csname align*\endcsname x & = 1 \\ y & = 2 \\ \csname endalign*\endcsname \end{document}

  • Compatibility issues between ibrackets and \underset/\overset/\substack
    by Sebastiano on December 10, 2025 at 10:22 pm

    The ibrackets package doesn't seem to work when I use \underset or \overset. \[ ]-\infty\underset{\substack{\uparrow \\ \frac{\pi}{2n}}}{,} a] \text { oppure } [a\underset{\substack{\uparrow \\ \frac{\pi}{2n}}}{,} \!+\infty[ \] I would like your opinion on how to adjust the spacing in this case as well, when I have a long text that should remain in normal style. \[ -\infty<\underset{\substack{\uparrow \\ punto \\di \\massimo}}{\frac{\pi}{2n}}<a \] I would prefer not to write the \text command three times. Here a MWE \documentclass[12pt,a4paper]{article} \usepackage{amsmath,amssymb,ibrackets} \begin{document} \[ ]-\infty\underset{\substack{\uparrow \\ \frac{\pi}{2n}}}{,} a] \text { oppure } [a\underset{\substack{\uparrow \\ \frac{\pi}{2n}}}{,} \!+\infty[ \] Ora in $x\in]-\infty,a]$, la funzione $f_n(x)$ è crescente ($k=0$) in $]-\pi/2n,\pi/2n[$, decrescente altrove, se \[ -\infty<\underset{\substack{\uparrow \\ punto \\di \\massimo}}{\frac{\pi}{2n}}<a \] allora \[ \sup_{\substack{]-\infty,a]\\ \frac {\pi}{2n}<a}} f_n(x)=f_n(c_n)=1/n^2 \] e qui si ha uniforme convergenza \end{document}

  • RawFeature={+axis={...}} equivalent to Rawaxis={...}?
    by Denis Bitouzé on December 10, 2025 at 7:26 pm

    (Disclaimer: I'm far to be an expert in variable fonts.) I am told that RawFeature={+axis={...}} can be shortened into RawAxis={...}. Nevertheless, as shown by the following MCE, that's the case when used in the optional argument \fontspec but not in the argument of \addfontfeatures: \documentclass{article} \usepackage{fontspec} \begin{document} \def\myfont{RobotoFlex-VariableFont.ttf} { \fontspec{\myfont}[RawFeature = {+axis={wght=800}}] g \addfontfeatures{ RawFeature = {+axis={wdth=50}}} g } { \fontspec{\myfont}[RawAxis={wght=800}] g \addfontfeatures{ RawAxis={wdth=50}} g } \end{document} Do you know why? And more generally, where is the +axis={...} syntax documented (it isn't covered in the fontspec documentation)?

  • PGFPlots filled polygons with colormap
    by John on December 10, 2025 at 5:30 pm

    I want to plot a bunch of polygons and fill each of them with color from colormap. I am trying the following unsuccessfully: \documentclass[tikz]{standalone} \usepackage{pgfplots} \pgfplotsset{compat=1.18} % or "newest" if your TeX supports it \usepgfplotslibrary{colormaps} \begin{document} \begin{tikzpicture} \begin{axis}[ colormap/viridis, colorbar, colorbar style={title={$v$}}, point meta min=0, point meta max=1, ] \addplot[draw=none, fill=mapped color, point meta=2.812245e-02] table [col sep=comma, x index=0, y index=1] {1.csv} -- cycle; \addplot[draw=none, fill=mapped color, point meta=8.440967e-01] table [col sep=comma, x index=0, y index=1] {2.csv} -- cycle; \end{axis} \end{tikzpicture} \end{document} since all of them come out as black polygons (with a viridis colorbar on the side). How do I solve this?

  • How to remove "LyX is already running in another instance" when it is not running (after crash)
    by hife on December 10, 2025 at 3:48 pm

    I am using single instance mode on Ubuntu 24.04. Sometimes, after LyX crashes, I cannot start it again and get the notification: "Server.cpp (1015): LyX is already running in another instance and 'use single instance' is active." But there is no LyX process running. How does LyX detect a running instance? And how can I manually remove whatever LyX is detecting here? (Logging out and back in works, but means I have to close all my other running programs.)

  • Horizontal stroke character "-" overlaps
    by Grzegorz Brzczyszczykiewicz on December 10, 2025 at 12:40 pm

    I defined a custom character: % strokeff.mf mode_setup; xoo#:=10pt#; yoo#:=10pt#; thick#:=5pt#; define_pixels(xoo, yoo, thick); beginchar(0, 7*xoo#, 7*yoo#, 0); %H pickup pencircle scaled thick; draw (0*xoo#, 3*yoo#)--(6*xoo#, 3*yoo#); endchar; end but when I wanted to type a sequence of three characters: \strokeff{\char0\char0\char0}, the result is this: and it looks really bad, the three lines should have a tiny space in between, but they don't. Here is what it looks like in text: And the underlying code: \documentclass{article} % Load fontenc for arbitrary font families \usepackage{fontenc} % Define a command that switches to the U/strokeff font family \newcommand{\strokeff}[1]{{\fontencoding{U}\fontfamily{strokeff}\selectfont #1}} \begin{document} \section*{StrokeFF Font Test} This is normal text. Here is a test using the \texttt{strokeff.mf} font: \bigskip \strokeff{0 1 2 3 4 5 6 7 8 9} \bigskip You can also include it inline, like \strokeff{\char0\char0\char0}, or at a larger size: {\Large \strokeff{\char0}} \end{document} The bounding box is a bit too small. Here are all the files I have in my folder https://drive.google.com/drive/folders/1lft8-6AbQIkV8psQN5ixUSZAwnei5dgN?usp=sharing and my characters' size should change but instead: only the spacing and the pen thickness changes. This is bad.

  • Citations with the changes package
    by Antonio Sesto on December 10, 2025 at 10:24 am

    I am using the packages changes for tracking updates to a shared .tex document, but I get errors caused by the \cite command. Consider this .tex file: \documentclass{article} \usepackage{cite} \usepackage{changes} \definechangesauthor[name=X, color=red]{X} \begin{document} \deleted[id=X]{This citation causes the error~\cite{a,b}} \begin{thebibliography}{100} \bibitem{a} Author A \textit{Title A}, 2000. \bibitem{b} Author B \textit{Title B}, 3000. \end{thebibliography} \end{document} It does not compile due to \cite{a,b}. The error is: \UL@stop ...alty \ifnum \lastkern =\thr@@ \egroup \egroup \ifdim \wd \UL@box... l.8 ...{This citation causes the error~\cite{a,b}} I've deleted a group-closing symbol because it seems to be spurious, as in `$x}$'. But perhaps the } is legitimate and you forgot something else, as in `\hbox{$x}'. In such cases the way to recover is to insert both the forgotten and the deleted material, e.g., by typing `I$}' I have tried some solutions found here and there: 1. Use the package ulem: \documentclass{article} \usepackage{cite} \usepackage[normalem]{ulem} \usepackage{changes} \setdeletedmarkup{\textcolor{red}{\sout{#1}}} \definechangesauthor[name=X, color=red]{X} \begin{document} \deleted[id=X]{This citation causes the error~\protect\cite{a,b}} \begin{thebibliography}{100} \bibitem{a} Author A \textit{Title A}, 2000. \bibitem{b} Author B \textit{Title B}, 3000. \end{thebibliography} \end{document} The error stays the same as before. The order of inclusion between changes and ulem has no influence on the error. 2. Protect the \cite command: Using this line: \deleted[id=X]{This citation causes the error~\protect\cite{a,b}} Nothing changes, same error. I have tried other random solutions without success. I was able to get rid of the error by: NOT including the package cite using ~\cite{a}~\cite{b} in place of ~\cite{a,b}: \documentclass{article} \usepackage{changes} \definechangesauthor[name=X, color=red]{X} \begin{document} \deleted[id=X]{This citation causes the error~\cite{a}~\cite{b}} \begin{thebibliography}{100} \bibitem{a} Author A \textit{Title A}, 2000. \bibitem{b} Author B \textit{Title B}, 3000. \end{thebibliography} \end{document} This code compiles with no errors. Clearly, there is no point in using changes if the old text must be modified. Is there a way to use changes when the source code contains \cite{a,b} or similar commands? Using natbib is not an option.

  • How to create PDF/X with latex

Package pdf Error: The standard 'X-6N' is unknown and has been ignored Type <return> to continue. ... l.2 ...lang=en-US,pdfversion=2.0,pdfstandard=x-6n} In the documentation on documentdata-supportcode we read: Beside the A-standards it is also possible to use the values X-4, X-4p, X-5g, X-5n, X-5pg, X-6, X-6n, X-6p for a PDF/X and UA-1 and UA-2 for PDF/UA standard. UA-2 should only be used together with PDF 2.0. Note that UA-1,2 work fine for me. I tried out all PDF/X standards and found only a single one which worked for me: x-4. By the way, all standards are tied more or less to a specific PDF version, not only the UA ones. Am I missing anything?

  • Exempt certain entry type from the short-form citation
    by bongbang on December 10, 2025 at 2:35 am

    In my document, a newspaper article should be cited without the author(s) or title, which I've implemented successfully. The problem is, except for citations to the same article that immediately follow, which are appropriately cited as "Ibid.", a subsequent citation will be the default short form, which consists of the author(s) and the title -- the opposite of what I want. How can I exempt newspaper entries from that short form (but not the "Ibid." form)? From a different solution to a related issue, I've included manual long-short switches in my code: \makeatletter \newcommand*{\ForceNextCiteShort}{\AtNextCite{\let\ifciteseen\@firstoftwo}} \newcommand*{\ForceNextCiteLong}{\AtNextCite{\let\ifciteseen\@secondoftwo}} \makeatother but plugging \let\ifciteseen\@secondoftwo only prepends the literal "secondoftwo" to my citation.

  • How many expl3 code lines are in the LaTeX kernel?
    by TeXtnik on December 9, 2025 at 11:27 pm

    I was courious to know how many line of expl3 code is in the LaTeX kernel. I run a python script (code below) to count the number of lines in each dtx file in the base directory of the LaTeX2e repository. The result I got is taht around 17% of the code is written in expl3. The breaking of this number for each file is below. I guess there are some improvements to be done: Don't count documentation lines. Include files in other directories (requires, tools ...) Use the striped tex files instead the dtx files? Some other? Can someone improve this estimate? (Apologize the use of python for these; I am force today to use a Windows machine, and I can't use some awk and shell tools to this work easier.

  • Environment that conditionally collects its content
    by campa on December 9, 2025 at 8:05 pm

    Disclaimer: This is a bit a XY problem, or rather: I have a problem X and I have a solution Y which works but does not really make me happy. Background: I have an environment, say {foo}, which I use for school tests. In the environment I can have solutions, whose presence is controlled by a boolean \ifsolution. Sometimes I want to print the pupils' version: easy, set \solutionfalse. Sometimes I want to print my own version: also easy, use \solutiontrue. Sometimes, I want to have a pdf file which contains both versions, first without and and then with solution: also easy, just use the environ package or the b specifier to collect the content and print it twice. Problem: All three versions can be easily obtained by \NewDOcumentEnvironment{foo}{+b}{...}{...}. However, this breaks synctex, and that might be a bit annoying. My idea was therefore to define an environment that collects its argument only in the last case, when I need both versions. I've managed it like this: \documentclass{article} \newif\ifsolution \def\solution#1{\ifsolution#1\fi} \newtoks\mytoks \long\def\collectfoo#1\end#2{% \mytoks\expandafter{\the\mytoks#1}% \def\tempa{foo}% \def\tempb{#2}% \ifx\tempa\tempb \def\next{\end{foo}}% \else \def\next{\mytoks\expandafter{\the\mytoks\end{#2}}\collectfoo}% \fi \next } \newenvironment{foo}[1]{% \ifdefined\foox\errmessage{You cannot nest {foo}!}\else\let\foox\relax\fi \par \def\nextA{}% \def\nextB{}% \ifcase#1\relax\solutionfalse\or% 0 = without solution \solutiontrue\else% 1 = with solution \def\nextA{\mytoks{}\collectfoo}% else once with and once without \def\nextB{\solutionfalse\the\mytoks\par\solutiontrue\the\mytoks}\fi \nextA }{% \nextB \par } \begin{document} \begin{foo}{0} An environment to see if the scan works: \begin{itemize} \item bla \item bar \end{itemize} If I've done it right, there should be nothing here: \solution{foo bar baz} \end{foo} \vskip2ex\hrule\vskip2ex \begin{foo}{1} An environment to see if the scan works: \begin{itemize} \item bla \item bar \end{itemize} If I've done it right, there should be something here: \solution{foo bar baz} \end{foo} \vskip2ex\hrule\vskip2ex \begin{foo}{2} An environment to see if the scan works: \begin{itemize} \item bla \item bar \end{itemize} If I've done it right, this should appear twice, fist without and then with something here: \solution{foo bar baz} \end{foo} \end{document} The result is what I expect, but of course my way to collect the environment's content is very rough. (No environment stack like amsmath or environ.) The question is basically: can this be done better?

  • Adding a style to biblatex makes my beamer document crash
    by Hrach on December 9, 2025 at 6:52 pm

    I am using biblatex on Overleaf to cite in my Beamer document. When I don't specify any styles, \usepackage{biblatex} \addbibresource{references.bib} works just fine. But I want the citations to look like [Author,Year]. When I try to add [style=authoryear] to the usepackage command the file just crashes with no explanation given. I am using pdflatex to compile.

  • Tikz comma shape
    by Andrew on December 9, 2025 at 6:40 pm

    I am using tikz to make a PA Dutch hex sign-like image. How can I make the comma-like shape that is seen below? I will ultimately be replicating it and rotating it around a center point, but I don't know how to get the basic shape to begin with.

  • drawing arc using intersection with triangle
    by troy on December 9, 2025 at 5:26 pm

    I've been trying to adapt the answer https://tex.stackexchange.com/a/239471 to the drawing I've been attempting, but I'm getting a strange result. I want draw an arc that begins and ends where it intersects with a triangle and spanning the interior of the triangle. My attempt at this is below. What I'm getting is a small, almond-shaped loop near one of the intersections. \documentclass[tikz]{standalone} \usepackage{pgfplots} \usetikzlibrary{fillbetween} \usetikzlibrary{3d} \usetikzlibrary{calc} \usetikzlibrary{intersections} \usetikzlibrary{perspective} \begin{document} \begin{tikzpicture}[scale=1.25, font=\sffamily] \pgfmathsetmacro{\alphasma}{1.4} \coordinate (O) at (0,0,0); \node at (O) {O}; \begin{scope}[scale=4,purple,very thick] \coordinate (X) at (0,0,1); \coordinate (Y) at (1,0,0); \draw[->] (O) -- (Y) node[anchor=north east]{\Large Y}; \draw[->] (O) -- (X) node[anchor=south]{\Large X}; \end{scope} \begin{scope}[3d view={90}{0.1}] \begin{scope}[scale=5,orange] \begin{scope}[rotate around y=20,black] \begin{scope}[rotate around z=-10,cyan] \begin{scope}[ canvas is xy plane at z=0, very thick ] \path[name path=lambdaArc] (O) circle [x radius=.95,y radius=.45]; \draw[name path=O-X-Y,dashed] (O) -- ($(O)!2*\alphasma!(X)$) -- ($(O)!2*\alphasma!(Y)$) -- cycle; \draw[red,thin, intersection segments={of=lambdaArc and O-X-Y,sequence=L3}]; \draw[orange,dashed] (O) circle [x radius=.95,y radius=.45]; \end{scope} \end{scope} \end{scope} \end{scope} \end{scope} \end{tikzpicture} \end{document} This is part of a larger diagram I am making. Deleting the extraneous parts leaves some scopes and structure that look unnecessary, but I left them as-is.

  • Parnote repeating itself inside tabularray package
    by Fr3d on December 9, 2025 at 12:50 pm

    Good afternoon, so I found about parnotes which work quite good, till I was in the search of a little annoyance in vertical lines in my table to look as booktabs. As suggested I tried the tabularraypackage because I had some issue with vertical clearance using the suggested nicematrix's {NiceTabular} environment. So when using \parnote{} insidea {tblr} environment, whether using the command cell{myNumberOfRows}{} = {}{} in the table preamble, or the given \SetCell[r=myNumberOfRows]{....} inside {tblr}, when I call \parnotes I get the note repeated as many times as specified by myNumberOfRows but with an increasing marking number, the same that was given in the table, as the last one is usually visible.

  • Strange output using AMSmath's \operatorname and fontsetup
    by msx on December 9, 2025 at 12:04 pm

    I have the following document \documentclass{article} \usepackage{fontsetup} \usepackage{amsmath} \newcommand{\coordRng}{\operatorname{\Gamma}} \begin{document} \(\coordRng (X)\) \(\Gamma\) \end{document} and when built by LuaLatex it has the following output: and I get the warning: Missing character: There is no 𝛤 (U+1D6E4) in font [NewCM10-Book.otf]:mode= Note that the Gamma that was supposed to be typeset by \coordRng is missing. Without the \operatorname command it typesets. If instead one does not use fontsetup, \coordRng also typesets fine.

  • How to customize the quote environment?
    by Cham on December 9, 2025 at 1:32 am

    I'm trying to customize the quote environment for a novel (citations at the beginning of each chapter), and I'm having troubles in setting custom vertical line spacing, horizontal line length, the left/right horizontal spacing (quote margins), and the space above and below the quotes. How can I add the following parameters to the squote macro defined in the code below? Also, take note that the epigraph macro will probably by erased because currently it's clashing with the centered chapter number. I need to control the quote's left and right margins (say 1 inch on both sides), or the left marging and line length. Also, I need to control the vertical line spacing inside the quotes (say constant one half spacing between each line or something else that would be elegant. Any expert suggestion on this, for small size text?). And the vertical space above and below the quote text should be adjusted for elegance with a constant spacing (I'll have to experiment to find the proper value. Any suggestion would be appreciated). I believe the vertical spacing between the chapter title and the quote is currently too large. And since I'm currently experimenting with the macros to find the best configuration and disposition, I may have to place the quotes on the right side of the page, below the chapter title, as what the epigraph is currently doing. All my previous experiments failed. Here's a MWE with my current settings to play with: \documentclass[11pt,twoside]{book} \usepackage[T1]{fontenc} \usepackage[tt=false]{libertinus} \usepackage[french]{babel} \usepackage[stretch=50]{microtype} \usepackage[letterpaper,left=1.25in,right=1in,top=0.5in,bottom=0.5in,includeheadfoot,headheight=15pt,showframe]{geometry} \raggedbottom %\onehalfspacing %\setstretch{1.25} \setlength{\parindent}{1.5em} \linespread{1.1} \usepackage{titlesec} \usepackage{graphicx} \usepackage[dvipsnames]{xcolor} \titleformat{\chapter}[display] {\normalfont\huge\bfseries\centering} {\chaptertitlename\ \thechapter}{20pt}{\Huge} \usepackage{epigraph} \renewcommand{\textflush}{flushleft} \setlength{\epigraphrule}{0pt} %\setlength{\epigraphwidth}{0.5\textwidth} \newcommand{\epig}[2]{\epigraphhead[60]{\epigraph{\itshape{#1}}{\itshape{#2}}}} % a macro that will probably be erased. % THIS MACRO TO BE EDITED AND ADJUSTED: \newenvironment{squote}{ \begin{quote}\itshape\small}{\end{quote}} \begin{document} \chapter{A Nice chapter title here} \epig{ Some very funny quote text from nobody, and here's another line of text just to make you smile, but really, this quote environment isn't satisfaying yet, because it's too close to the chapter title. }{} \begin{squote} This is one fancy line of text to show a pretty medium long quote line, \\ this is the next line quote text to say anything wildly funny. This is another useless text of line just to show how smart I'm not. \end{squote} Some dummy text to show the paragraph spacing below the quoted text above. Oh well, another line of dumb text, and yes maybe I should use the lorem ipsum package to add something wild in there. But nevermind, I don't need it! \end{document} Here's a preview of what this MWE is doing:

  • How to distribute items (cards) evenly on a A4 page in Latex?

  • How to layout the two-side notes using Latex
    by xuehao on December 8, 2025 at 4:49 am

    The following is an example from an English book. I'm planning to rewrite it in latex. The layout is with an itemize of points in the middle, and with "CONNECTIONS" notes along the two sides. I tried to solve it using TikZ, but the vertical align is hard to control. \documentclass{article} \usepackage{graphicx} % Required for inserting images \usepackage{tikz} \begin{document} \begin{center} \begin{tikzpicture} \node[draw,text width=3.1cm] at (0cm,0) {CONNECTIONS Because \\ \vspace{\baselineskip} It \\ and \\ Though \\ Since ... not \\ only \\ but also \vspace{\baselineskip} }; \node[draw,text width=6.3cm] at (5.1cm,0) {\begin{center} POINTS \end{center} 1. Brazil needs to be developed. \\ 2. New city, Brasilia, built 600 miles, Rio. \\ 3. Designed Lucio Costa. \\ 4. Became capital 1960. \\ 5. Planned for modern living. \\ 6. People at first reluctant to go. \\ 7. 1960 - population increasing. \\ 8. Established as capital. }; \node[draw,text width=3.1cm] at (10.2cm,0) {CONNECTIONS \vspace{\baselineskip} which was built \\ and which \\ \vspace{\baselineskip} It \\ but \\ However, with the increase }; \end{tikzpicture} \end{center} \end{document} Anyone could give me any clever solution for this task?

  • Drawing a sphere and ellipsoid together
    by Knudsen on December 8, 2025 at 4:00 am

    I would like to draw a sphere, of radius 3, and an ellipsoid of semi-axis 2, 3 and 4 together. They intersect at two great circles on the sphere (marked in red). I started out with the sphere and the great circles: \documentclass[border=2mm]{standalone} \usepackage{tikz} \usetikzlibrary{3dtools}% https://github.com/marmotghost/tikz-3dtools \begin{document} \begin{tikzpicture}[3d/install view={phi=120,theta=70},line cap=butt, line join=round,declare function={R=3;},c/.style={circle,fill,inner sep=1pt}] \path (0,0,0) coordinate (O) ; \draw[blue,3d/screen coords] (O) circle[radius=R]; \shade[ball color=white,3d/screen coords,opacity=0.7] (O) circle[radius=R]; % \shade[ball color=blue!30,3d/screen coords,opacity=0.7,xscale=2,yscale=3,zscale=4] (O) circle[radius=1]; \path pic[blue]{3d/circle on sphere={R=R,C={(O)}}}; \path pic[red]{3d/circle on sphere={R=R, n={(0.592,0,-1)}}}; % plane x = sqrt{7/10) z \path pic[red]{3d/circle on sphere={R=R, n={(0.592,0,1)}}}; % plane x = sqrt{7/10) z \draw[3d/hidden] (0,0,0) -- (0,0,R) (O)--(R,0,0) (O)--(0,R,0) (O)--(0,-R,0); \draw[3d/visible, -stealth] (R,0,0) -- (R + 4,0,0) node[below]{$x$}; \draw[3d/visible, -stealth] (0,R,0) -- (0,R + 1,0) node[right]{$y$}; \draw[3d/visible, -stealth] (0,0,R) -- (0,0,R + 1.5) node[above]{$z$}; \end{tikzpicture} \end{document} and everything is right so far: but when I remove the comment on the line that I would expect to draw the ellipsoid \shade[ball color=blue!30,3d/screen coords,opacity=0.7,xscale=2,yscale=3,zscale=4] (O) circle[radius=1]; I get something that is far from what I expected, including the fact that the zscale is not understood. How can one add the intersecting elipsoide to this image?

  • How to add a mirror like shadow effect to a title?
    by Cham on December 8, 2025 at 12:44 am

    I would like to add a reversed gray shadow under a title to mimmic a mirror effect. How can we do that with standard pdflatex (the live tex distribution)? Currtently, the code below only add a dull projected shadow under the title. Is there a way to vertically reverse the shadow? Here's a MWE to edit and play with: \documentclass[11pt,twoside]{book} \usepackage[T1]{fontenc} \usepackage[tt=false]{libertinus} \usepackage[french]{babel} \usepackage[stretch=50]{microtype} \usepackage[letterpaper,left=1.25in,right=1in,top=0.5in,bottom=0.5in,includeheadfoot,headheight=15pt]{geometry} \usepackage[dvipsnames]{xcolor} \usepackage{shadowtext} \begin{document} \begin{titlepage} \shadowoffsetx{2.5pt} \shadowoffsety{3.5pt} \shadowcolor{gray!40} \centering \vspace*{\baselineskip} \vfill {\textcolor{black}{\fontsize{26}{0}\selectfont\sffamily\textbf{\shadowtext{DOCUMENT TITLE}}}} \\[2.5\baselineskip] \vfill {\textcolor{black}{\huge\sffamily Author}} \vfill \end{titlepage} Text \end{document}
