Consider the code: \documentclass{book} \usepackage{graphicx} \usepackage{tikz} \usetikzlibrary{calc} \begin{document} \thispagestyle{empty} \begin{center} \begin{tikzpicture} \fill[red] rectangle (8,6); \foreach \k in {0,30,...,360} \node at ($(4,3)+(\k:2)$) {\includegraphics[width=1.7em]{example-image-a}}; \end{tikzpicture} \end{center} \end{document} which produces: QUESTION: How may I modify this code in order produce an ellipse (instead of circle) of images? Thank you.

Consider the following code: \documentclass{article} \usepackage{tikz} \usetikzlibrary{% decorations.text,% mindmap,% } \begin{document} \begin{tikzpicture} \path[ adddecrev/.style={% postaction={decorate, decoration={text along path, text={##1}, raise=3pt, }}}, small mindmap, ] node (norm) [root concept, concept, adddecrev={AAA AAA|\hskip 7.5pt| ||AAAAA AAA{\kern10ptA}A AA AA}] {AAAAAAAAA} [counterclockwise from=120] % removing this child eliminates the warnings child { node [concept, adddecrev={X{\kern-2ptX}{\kern-1ptX}{\kern4ptX}{\kern0ptX}X|\hskip8pt| ||X{\kern-2ptX}X{\kern-1ptX}{\kern-1ptX} X{\kern-3ptX}{\kern-1ptX}l{\kern-1ptX}|\hskip-2pt|X||{\kern-1ptX}|\hskip4pt|X||{\kern-2ptX}|\hskip-2pt|X|| }] {MMMMMMMM} } ; \end{tikzpicture} \end{document} In TL2020, this compiles without complaint for either pdfLaTeX or LuaLaTeX. In TL2025 or 2026, it complains Missing character: There is no A in font nullfont! In TL2024, the complaint is Missing character: There is no @ in font nullfont! In TL2022 and TL2023, the complaint is Missing character: There is no ? in font nullfont! In TL2021, the complaint is Missing character: There is no > in font nullfont! What causes these differences? Usually the nullfont warnings relate directly to problematic characters in the source. The A suggests that might be the case, except that removing the X line makes the problem disappear. Moreover, for earlier installations, the characters complained of bear no obvious relation to the input and I'm not sure where they are coming from or what the problem is. I also can't see anything obviously wrong with the code specifying the text for the decoration, despite rereading the relevant part of the manual. What is happening here? Is my code erroneous? If so, how can I correct it? In any case, is there a way to avoid the problem with a current TeX Live?

I'm not sure, but I think the dimensions of a table row are like this: What I need is a (breakable, horizontally and vertically centered) multicolumn with an exact height of (1,2,3,...) baselineskips including the \hline above it: How do I correctly dimension a rule for this? \newcommand{\DynamicRowRule}[1]{% #1 = number of rows \rule[ \dimexpr -#1\baselineskip/2 +\baselineskip/2 -0.3\baselineskip +0.5\arrayrulewidth\relax ]{1pt}{\dimexpr #1\baselineskip - \arrayrulewidth\relax}} Hints: a) The main table can have different widths, so I have defined a P-column with dynamic width. b) Nothing should be done with \arraystretch (since the original table contains hundreds of rows whose height is calculated, unimportant for the problem here) \documentclass{article} \usepackage{tabularx} % Input: \setlength\arrayrulewidth{3.45pt}% Test \makeatletter % i) Define 'P' column with dynamic width and breakable \newcolumntype{P}{>{\centering\arraybackslash}p{\dimexpr\TX@target-2\arrayrulewidth\relax}} \makeatother % ii) Define row strut for 1,2,3,... rows \newcommand{\DynamicRowRule}[1]{% #1 = number of rows \rule[ \dimexpr -#1\baselineskip/2 +\baselineskip/2 -0.3\baselineskip +0.5\arrayrulewidth\relax ]{1pt}{\dimexpr #1\baselineskip - \arrayrulewidth\relax}} \newcommand\TestRule{\rule[-0.3\baselineskip]{1pt}{\baselineskip}} \begin{document} \section{Table with Title with a Height of (1,2,\dots) baselineskips minus arrayrulewidth} \noindent \begin{tabularx}{88mm}{|X|c|c|} \hline \multicolumn{3}{|@{}P@{}|}{Centered Title pq\DynamicRowRule{3}} \\ \hline A & B & C \\ \hline Testrule for 1 row: \TestRule pq & Column 2 & Column 3\\ \hline \end{tabularx} \end{document}

I would need your help to draw a surface of genus three like in the picture I attached. More specifically, I aim to draw a torus (surface of genus one) and below the surface of genus three realised by mean of some surgeries on the surface. I already drawn the torus by myself and I need help with the genus 3 surface. As you can see, the torus I drew is not exactly as on paper. Could help me? I also added some notes about colours of curves. Moreover, I'd like the surface is filled with the pattern [pattern=north west lines, pattern color=pallido], where pallido is just a colour I defined in RGB (it's already in the code). In the picture I do not need the names of colours, that's only for you.

It's been decades that I did anything with (La)TeX and forgot all about it. So I asked an AI to generate it for me. The goal is to have ca. 96 individually customizable text boxes on a page. The AI generated a class file that does that and a very brief .tex . When I run pdflatex (on Ubuntu), it complains: ! LaTeX Error: Command \Box already defined. Or name \end... illegal, see p.192 of the manual. See the LaTeX manual or LaTeX Companion for explanation. Type H <return> for immediate help. ... l.74 \newcommand{\Box01X}{1} \newcommand{\Box01Y}{13} ? H Your command was ignored. Type I <command> <return> to replace it with another command, or <return> to continue without it. What I see is that the AI tries to create special commands for each box, but LaTeX recognises Box01X etc. as the pre-existing Box command. Why is that and how are we supposed to define new commands? The error refers to p.192 of " the" manual but current manuals listed on: https://www.latex-project.org/help/documentation/#general-documentation don't even have that many pages. The 'H' command is ignored by pdflatex. Thanx for any guidance,

I am trying to generate a quiz where I can generate a file answers.txt containing the id of each question, the x,y location on the page, the width,height and the answer.

An MWS is as follows. \documentclass{ctexart} \usepackage{amsmath} \makeatletter %change English parenthesis for Chinese parenthesis \def\tagform@#1{\maketag@@@{（\ignorespaces#1\unskip\@@italiccorr）}} %\newcommand{\eqref}[1]{\textup{\tagform@{\ref{#1}}}} \makeatother \begin{document} 测试文字测试文字测试文字测试文字测试文字测试文字测试文字测试文字测试文字测试文字。我们有如下结论： \begin{equation} y=x^2+7x+9\text{。} \end{equation} 测试文字测试文字测试文字测试文字测试文字测试文字测试文字测试文字测试文字测试文字。 \end{document} To change English parenthesis for Chinese parenthesis in equation numbers, I revised the definition of \tagform@ is amsmath. While since there are some spaces after the Chinese parenthesis, the Chinese parenthesis are not aligned to the right side. So is there anyway to fix this?

This is a follow-up to this question. I have a user-defined command which allows numbering & referencing of a single line in a starred, multiline equation environment, replacing the need to use an un-starred environment with \nonumber at the end of every other line. My first-attempt definition caused problems around ordering when using \labelcref, which the original question sucessfully resolved. The solution was the following command: \makeatletter \newcommand*\my@make@df@tag@@[1]{% \cref@old@make@df@tag@@{#1}% \let\cref@old@df@tag\df@tag \expandafter\gdef\expandafter\df@tag\expandafter{% \cref@old@df@tag \def\cref@currentlabel{% [equation][\arabic{equation}][]#1% }% }% }% \newcommand*\my@make@df@tag@@@[1]{% \cref@old@make@df@tag@@@{#1}% \let\cref@old@df@tag\df@tag \expandafter\gdef\expandafter\df@tag\expandafter{% \cref@old@df@tag \toks@\@xp{\p@equation{#1}}% \edef\cref@currentlabel{[equation][\arabic{equation}][]\the\toks@}% }% }% \newcommand{\TAG}[1]{% \refstepcounter{equation}% \begingroup \let\make@df@tag@@\my@make@df@tag@@ \let\make@df@tag@@@\my@make@df@tag@@@ \tag{\theequation}% \endgroup \label{#1}% }% \makeatother (credit to @Ulrich Diez for the solution and @Ziv for the appendix patch). This command worked perfectly with the \documentclass{article} used in the original question's MWE. Unfortunatley, I have since found that with \documentclass{book} the previous bug returns. Is there a patch to the original solution, or a new solution, that will fix this?

Since the following line: is going too close to the right margin of the page, I changed the text size of the four larger-text fractions from normal to footnotesize: $$\cos(\alpha) = \frac{\frac{1}{2\tan(36^\circ)}}{\frac{3+\sqrt{5}}{4}} = \begin{footnotesize}\frac{\raisebox{-2pt}{1}}{2\tan(36^\circ)}\bm{\cdot}\frac{\raisebox{-2pt}{4}}{3\!+\!\sqrt{5}} = \frac{\raisebox{-2pt}{4}}{2(3\!+\!\sqrt{5})\!\tan(36^\circ)}\end{footnotesize} \rightarrow m\angle\alpha = \arccos\!\raisebox{-3pt}{$\Bigl($}\!\begin{footnotesize}\frac{\raisebox{-2pt}{4}}{2(3\!+\!\sqrt{5})\!\tan(36^\circ)}\end{footnotesize}\!\raisebox{-3pt}{$\Bigr)$} \approx\!58.2825^\circ$$ But the only characters that were reduced were the numerators I lowered closer to the fraction bar. To shrink the text in the denominators, should I put them inside raisebox too and just "raise" them 0pt? Or is it better to just put the whole thing in single-$ math mode and just use \dfrac instead of \frac since it doesn't really need to be centered anyway (since it takes up the entire width)? Edit: Changing $$ $$ to \[ \] didn't help.

I am working with optex 1.17, which comes with TeXLive 2023. I am creating slides, but I am having a problem with the counter at the beginning, on the cover slide.

The following MWE is indicated to produce an accessible PDF, using lualatex in TeXLive-2026, however it produces 26 adaptable failures when checked on the axesCheck web tool. \DocumentMetadata{ lang=en-US, pdfstandard=ua-2, tagging=on, tagging-setup={math/setup={mathml-AF,mathml-SE}} } \documentclass{article} \usepackage{unicode-math} \begin{document} \title{Accessible \LaTeX} \author{I. M. Author} \date{\today} \section{Accessible Math Example} The quadratic formula is: \begin{equation} x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \end{equation} \end{document} I have tried the compilation with and without the unicode-math package and the result is the same. Removal of the equation produces a PDF that is WCAG-compliant, using the same web tool. A foo-luamml-mathml.html file is produced from the lualatex compilation of foo.tex and, when opened in a browser, appears to correctly render the equation. Nonetheless, the issue is to produce a WCAG-compliant PDF. The above MWE also follows the example shown on the LaTeX Tagging Project web page. The downloaded PDF from that example also fails the WCAG-compliance check. What am I missing or misunderstanding?

I am a little bit confused with the new babel-german v3.0, where the naming convention has a breaking change: post-1996 convention is now the default one. Is it OK to still use ngerman in current documents? Would it be different with using the new german option? Should the replacement of ngerman be german or german-de/german-germany? The documentation suggests that "it is always advisable to use a more precise option such as german-de". Thus perhaps it should be safer and more stable to use german-de instead of german. For package authors passing/detecting language options, should there be any caution with this new change? (For example, shall one need to detect the version and apply different rules separately?) Thanks so much!

Hi I tried looking for solutions online, but found nobody with this error, so I think it justifies this question. I wanted to copy the rather common template I've seen from various lecture notes and books. The template in question is the pure and applied undergrad text from the AMS monograph website: https://www.ams.org/arc/books/book-produce.html An example of the template on a chapter page I want to emulate is this one: This was taken from the template given in the link on the AMS website, once downloaded. Yet when I try do use the exact same template in Overleaf, I get pretty much the same thing, but without any page numbering: I highly doubt this is an Overleaf issue, so that's why I wanted to ask here. I would appreciate any assistance/instructions on how to turn on page numbering (from what I can see it is already enabled). Thanks.

I am preparing a project that involves representing the Italian Parliament using a semicircle made of colored dots, as shown in the following image: I have tried to create something using the wheelchart package (page 19 of the manual), which allows generating similar charts. However, I am unable to automatically increase the number of dots per row. For example, in the figure there are 12 dots per row, but I would like a more customizable (for example 7 balls for every radius) and automatic solution to control this. I prefer big dots and not balls. \documentclass{article} \usepackage{tikz} \usepackage{wheelchart} \begin{document} \begin{tikzpicture} \pgfkeys{ /wheelchart, discrete, discrete pic={\shade[ball color=\WCvarB] (0,0) circle[radius=2pt];}, discrete sort=angle, discrete space at borders=false, start angle=180, total angle=180, value=\WCvarA } \wheelchart{ 120/blue/, 45/green/, 40/red/, 25/orange/, 10/purple/, 5/teal/ } \end{tikzpicture} \end{document}

I'm looking for something really simple, to remove completly the bar form the long s. I don't know how to do it properly.

There are various packages that will conveniently give extensible arrows with sub/superscripts. I'm aware of: amsmath (only for basic arrows) mathtools extarrows chemarrow You can of course do the same thing with TikZ or similar. I want something similar, but with no arrowheads at all. What's the best way to achieve that? I can do it with TikZ, but the mildly annoying part would be matching the standard arrow height and width. Should I figure out how to use the internal \arrowfill@ command in amsmath? My application is essentially marking a chain of edges connected in a graph, with various labels on the edges. Here's one attempt using a text em-dash. You can see that the em-dash isn't the same as the math-mode arrow. \documentclass[12pt]{amsart} \begin{document} \[ x \overset{\mathcal{U}}{\mathbin{\text{---}}} y \overset{\mathcal{U}}{\longrightarrow} z\] \end{document}

I am compiling a LaTeX document in VS Code using the LaTeX Workshop extension on Windows 11. My document uses: chemnum / chemstyle nomencl biblatex mhchem Originally my latexmk tool was configured with: -pdf However, this produced incorrect compound labels when using chemnum with a scheme environment (temporary labels such as TMP1, TMP2 were not replaced). Following advice from a previous question, I changed the compilation pipeline to: -pdfps, (see my previous question: VS Code LaTeX Workshop: how to configure settings.json when using both chemnum and nomencl?) This indeed fixes the chemnum labeling issue. However, now I cannot include PNG graphics. For example: \begin{figure} \centering \includegraphics[scale=0.8]{random.png} \caption{random} \label{fig:random} \end{figure} produces the error: Cannot determine size of graphic (no BoundingBox) (This also does not work with [width=0.5\textwidth] or when using a .pdf image instead of .png.). In the real document there are several PNG graphics. I would also like all PNG images to be included with a fixed scale=0.8. I found the following related question, but it is quite old, so perhaps there is a more up-to-date solution: Cannot determine size of graphic settings.json { "latex-workshop.latex.tools": [ { "name": "latexmk", "command": "latexmk", "args": [ "-synctex=1", "-interaction=nonstopmode", "-file-line-error", "-pdfps", "%DOC%" ] }, { "name": "makenomenclature", "command": "makeindex", "args": [ "%DOCFILE%.nlo", "-s", "nomencl.ist", "-o", "%DOCFILE%.nls" ] } ], "latex-workshop.latex.recipes": [ { "name": "latexmk → nomencl → latexmk", "tools": [ "latexmk", "makenomenclature", "latexmk" ] } ], "latex-workshop.latex.recipe.default": "latexmk → nomencl → latexmk", "latex-workshop.latex.autoBuild.run": "never", } aromatic-compounds.eps https://drive.google.com/file/d/1faCOOvd5xcVAF_KZqhx7vAI0Mqh7pmF6/view?usp=sharing main.tex \documentclass{article} \usepackage{geometry} \usepackage{graphicx} \usepackage[version=4]{mhchem} \usepackage{chemstyle} \usepackage{chemnum} \usepackage[backend=biber]{biblatex} \addbibresource{bib.bib} \usepackage{nomencl} \makenomenclature \begin{document} \nomenclature{A}{a} \printnomenclature \section{First} \cite{knuth1984texbook} \begin{scheme} \replacecmpd{benezen} \replacecmpd{toluene} \includegraphics[scale=0.8]{aromatic.eps} \caption{Aromatic-compounds} \label{aromatic-compounds} \end{scheme} \begin{figure} \centering \includegraphics[width=0.5\textwidth]{random.png} \caption{random} \label{fig:random} \end{figure} \refcmpd{benezen, toluene} \printbibliography \end{document} bib.bib @book{knuth1984texbook, title={The texbook}, author={Knuth, Donald Ervin and Bibby, Duane}, volume={15}, year={1984}, publisher={Addison-Wesley Reading} }

See the following code: \documentclass[tikz]{standalone} \usetikzlibrary{shapes.multipart, patterns.meta} \begin{document} \begin{tikzpicture}[text width=3cm, draw, rounded corners] \node[draw, fill=yellow, postaction={pattern color=orange, pattern={Lines[distance=10mm,angle=45,line width=5mm]}} ] at (0,0) {Example}; \node[draw, rectangle split, rectangle split parts=2, rectangle split part fill={yellow,white}] at (0,-1) {Title\nodepart{second}Element content}; \end{tikzpicture} \end{document} I would like the "Title" part to look like the "Example" node. I have tried to replace the yellow,white instruction by {yellow, postaction={pattern color=orange, pattern={Lines[distance=10mm,angle=45,line width=5mm]}} },white But it dosn't work. Can you help me? Thanks.

I'm drawing a 3D rectangle (which should be a plane, represented by the letter "H"). At the top left corner, at 'C', I want to project a $H$ in mathematical font onto the plane. I've used a cm matrix for this. The position is correct, but I've noticed that the serifs of the 'H' are parallel, despite using $H$, so it doesn't look like mathematical font. What do I need to do? PS: I think, the $H$ should look something like this here: Unfortunately, I can't present it any better. \documentclass[margin=5pt, tikz]{standalone} \usepackage{tikz} \usetikzlibrary{calc} \begin{document} \begin{tikzpicture}[ x={(-4.85mm,-4.85mm)}, y={(10mm,0mm)}, z={(0,10mm)}, font=\footnotesize, ] %\coordinate[label=below:$O$](O) at (0,0,0); \coordinate[label=right:A](A) at (0,2,0); \coordinate[label=B](B) at (0,2,2); \coordinate[label={[anchor=south west, inner sep=1pt]{C $H$ (as it should be)}}](C) at (-2.5,-1.5,2); \coordinate[label=left:D](D) at (-2.5,-1.5,0); \draw[] (A) -- (B) -- (C) -- (D) --cycle; \path let \p1 = ($(B)-(C)$), \p2 = ($(C)-(D)$), \n{len1} = {veclen(\x1,\y1)}, \n{len2} = {veclen(\x2,\y2)}, \n1 = {\x1/\n{len1}}, \n2 = {\y1/\n{len1}}, \n3 = {\x2/\n{len2}}, \n4 = {\y2/\n{len2}} in node[cm={\n1, \n2, \n3, \n4, (C)}, anchor=north west, inner sep=1pt, %transform shape, % no effect ]{H $H$ \mbox{$H$}}; % CoSy \begin{scope}[-latex, thick, shift={(0,-2,2)}] \foreach \P/\s/\Pos in {(1,0,0)/x/above, (0,1,0)/y/right, (0,0,1)/z/right} \draw[] (0,0,0) -- \P node[\Pos, pos=0.9,inner sep=3pt]{$\s$}; \end{scope} \end{tikzpicture} \end{document}

I'm trying to use \definelistalternative to alter the way a part is displayed in the Table of Contents. That appears to be working but I'm having trouble with the conversion of the \currentlistentrynumber to the text provided in the \defineconversion[Parts] line in this example. I know that the \convertnumber{Parts}{...} works because it is used in the first chapter using hard-coded integers and it returns First, Second, or Third. But the \convertnumber{Parts}{\currentlistentrynumber} throws an error (strangely at the numberalign=flushright under the chapter level of setuplist); and I assume that is because \currentlistentrynumber is not treated as its integer value. I tried passing it to a custom command \ConvertPartNbr declared in this example, but the error is the same. How can I get to the value of \currentlistentrynumber in order to convert it? It is under \startsetups [PartsTOCsu], at line %{Part \convertnumber{Parts}{\currentlistentrynumber}{.}}% currently commented out. Thank you. Also {Part \convertnumber{Parts}{\currentlistentrynumber}} and {Part \expandafter\convertnumber{Parts}{\currentlistentrynumber}} both throw the error of csname overload > warning, protection level 3, control sequence 'P', properties 'permanent', file './mwe4.tex', line 6 csname overload > warning, protection level 3, control sequence 'convertnumber', properties 'permanent', file './mwe4.tex', line 6 !
