How to stop the effect of the \appendix command and return to regular numbering instead of letters.

I have a document, where I describe topics (one page per topic). I want to have a list of all topics together with some additional information at the beginning of the document. So far my solution is this: First I make a file whrere the list is at the end of the file. MWE (file called Themen.tex): \documentclass[a4paper,12pt]{scrartcl} \usepackage{longtable} \newcounter{nummer} \def\Uebersicht{% Nr. & Topic & A & Page \\\hline \endfirsthead Nr. & Topic & A & Page \\\hline \endhead } \usepackage{hyperref} \newcommand{\Thema}[3]{% \refstepcounter{nummer}\label{#3}% \begin{center} \LARGE #1 \end{center} \begin{table}[h!] \centering \begin{tabular}{p{4.3cm}p{1cm}p{11cm}} A: && #2 \end{tabular} \end{table} \hrule \appto\Uebersicht{\getrefnumber{#3} & #1 & #2 & \pageref{#3} \\} } \begin{document} \clearpage \Thema{A}{A}{A} \clearpage \Thema{B}{B}{B} \clearpage \Thema{C}{C}{C} \clearpage \Thema{D}{D}{D} \clearpage \clearpage \begin{longtable}[h!]{r|p{0.48\linewidth}|p{0.34\linewidth}|r} \centering \Uebersicht \end{longtable} \end{document} Afterwards, I rearrange the pages. MWE: \documentclass{scrartcl} \usepackage{pdfpages} \pdfximage{Themen.pdf}% Read entire PDF \edef\totalpages{\the\pdflastximagepages}% Store number of pages \edef\lastbutonepage{\number\numexpr\totalpages-1}% Store last page - 1 \begin{document} \includepdf[pages=last]{Themen} \includepdf[pages=1-\lastbutonepage]{Themen} \end{document} The problem is, that in the end, the cross-references to pages inside the document, as well as external links that I put in the description of the topics do not work. How can I achieve what I want with working links (either with my 2-file-solution or directly)?

I am writing a paper whose formatting rules for both citations and the bibliography require that the date of a reference, when it refers to the copyright year, be preceded by a lowercase "c" with no intervening space. Therefore, I would like to be able to assign the date field with the corresponding year preceded by the letter c by implementing a new date format, similar to formats such as <date>~, <date>?, etc., but restricted to accepting only the year. With this, the copyright year would be specified in the bib file as follows: date = {c<year>} Using the authoryear style from BibLaTeX as an example, the following MWE would apply: \documentclass{article} \usepackage[style=authoryear]{biblatex} \setlength{\parindent}{0pt} \begin{filecontents}{\jobname.bib} @article{aksin, author = {Aks{\i}n, {\"O}zge and T{\"u}rkmen, Hayati and Artok, Levent and {\c{C}}etinkaya, Bekir and Ni, Chaoying and B{\"u}y{\"u}kg{\"u}ng{\"o}r, Orhan and {\"O}zkal, Erhan}, title = {Effect of immobilization on catalytic characteristics of saturated {Pd-N}-heterocyclic carbenes in {Mizoroki-Heck} reactions}, journaltitle = {J.~Organomet. Chem.}, date = {c2006}, volume = 691, number = 13, pages = {3027-3036}, indextitle = {Effect of immobilization on catalytic characteristics}, } @article{glashow, author = {Glashow, Sheldon}, title = {Partial Symmetries of Weak Interactions}, journaltitle = {Nucl.~Phys.}, date = {c1961}, volume = 22, pages = {579-588}, } \end{filecontents} \addbibresource{\jobname.bib} \begin{document} \section{\citeauthor{aksin}} \verb|\cite{aksin}|: \cite{aksin}. \verb|\textcite{aksin}|: \textcite{aksin}. \section{\citeauthor{glashow}} \verb|\cite{glashow}|: \cite{glashow}. \verb|\textcite{glashow}|: \textcite{glashow}. \printbibliography \end{document} With this MWE, the desired output would be as follows: For reference, the document shown in this screenshot was compiled using the year field instead of date in the bib file; otherwise, the c<year> value is considered invalid and consequently ignored. However, in that case, sorting by year does not work. Given these requirements, is there a way to implement this? I have created a custom BibLaTeX style package with a few modifications that I use exclusively for this paper, so this would be implemented in the package files rather than in the document preamble.

this question is similar to add latex counter to memoize context, I just wanted these to be separated to make it easier to find the questions later. Basically this boils down to "where does xcolor" store its color definitions? So what needs to be added so in the following example the two externs have different contexts? \documentclass[a4paper]{article} \usepackage{memoize} \usepackage{tikz} \usepackage{xcolor} \colorlet{myColor}{blue} \NewDocumentEnvironment{step}{}{% \begin{tikzpicture}[myColor]% }{% \end{tikzpicture}% } \mmzset{auto={step}{ memoize, csname meaning to context={step}, csname meaning to context={environment step end aux\space} }} \begin{document} \begin{step} \node[draw,rectangle] {hello world}; \end{step} \colorlet{myColor}{red} \begin{step} \node[draw,rectangle] {hello world}; \end{step} \end{document} (with memoize the nodes are draw red in both pictures, without memoize the first is blue, the second is red)

I've been writing some latex code which should be able to memoize. As I'm really no expert regarding the latex internals, I'm having a hard time adding a counter to the context. I thought latex stores counter values in \c@<counter name> but still \documentclass[a4paper]{article} \usepackage{memoize} \usepackage{tikz} \newcounter{stepCnt} \setcounter{stepCnt}{0} \NewDocumentEnvironment{step}{}{% \begin{tikzpicture}% }{% \end{tikzpicture}% } \makeatletter \mmzset{auto={step}{ memoize, csname meaning to context={step}, csname meaning to context={environment step end aux\space}, csname meaning to context={c@stepCnt} }} \makeatother \begin{document} \begin{step} \node[draw,rectangle] {hello world -- counter at \arabic{stepCnt}}; \end{step} \stepcounter{stepCnt} \begin{step} \node[draw,rectangle] {hello world -- counter at \arabic{stepCnt}}; \end{step} \end{document} This leads to the following output: When disabling memoization: \documentclass[a4paper]{article} \usepackage{tikz} \newcounter{stepCnt} \setcounter{stepCnt}{0} \NewDocumentEnvironment{step}{}{% \begin{tikzpicture}% }{% \end{tikzpicture}% } \begin{document} \begin{step} \node[draw,rectangle] {hello world -- counter at \arabic{stepCnt}}; \end{step} \stepcounter{stepCnt} \begin{step} \node[draw,rectangle] {hello world -- counter at \arabic{stepCnt}}; \end{step} \end{document} seems to result in two externs with the same hash/context. Any idea how to fix this? Note: The construct with environment step end aux etc (basically "how to capture a NewDocumentEnvironment" is from https://github.com/sasozivanovic/memoize/issues/20.

In an effort to meet federal (US) law for accessibility of documents, I have started experimenting with various accessibility enhancements for my LaTeX source files. (As a stable TeX user for over 30 years, this is a big change to process.) Following advice posted here and at the LaTex Tagging Project, I have been including the following as the first line in my source: \DocumentMetadata{lang = en, pdfstandard = ua-2, pdfstandard = a-4f, tagging=on, tagging-setup={math/setup=mathml-SE}} I must say, this has thus far worked marvelously. When I compile using LuaLaTeX, I get a PDF that passes all my institution's accessbility checkers. So far, a lifesaver. The sole issue I've experienced is in using the package mdframed. When I attempt to use the package, as in something like \begin{mdframed} This is a key point! \end{mdframed} I get the following fatal error: l.74 This is a key point! ? h Try typing <return> to proceed. If that doesn't work, type X <return> to quit. No output is created. I have toggled on and off all reasonable combinations of packages, and the error only occurs when mdframed is invoked while the DocumentMetadata is inserted. I feel that I am a bit over my head here, so am looking for an explanation of this conflict or a fix for it. I fully admit that I may have something set incorrectly in the DocumentMetadata call, because I do not completely understand the effect that is having.

I have a reproducible problem with htlatex on Windows with MiKTeX 26.2. I tested it on a fresh single-user MiKTeX installation after a complete reinstall. Minimal example: \documentclass{article} \title{Publikacje} \author{Leszek J Chmielewski} \date{} \begin{document} \maketitle Test. \end{document} Command used: htlatex lchmiel_publications.tex "xhtml,charset=utf-8,html5" "" "" The process seems to hang after the first LaTeX pass. The terminal ends with: No file lchmiel_publications.aux. [1] [2] and then it does not continue. What I checked: ordinary latex compilation works the issue also happens for the minimal example above reinstalling MiKTeX did not help I also tested in a short directory path without spaces, with the same result So this does not seem to be caused by my document content. I also tried make4ht, but that was problematic as well: latex lchmiel_publications.tex tex4ht lchmiel_publications.dvi t4ht lchmiel_publications but this has output the file lchmiel_publications.html without any formatting, one line of text: Publikacje Leszek J Chmielewski Test. 1 Trials to include the formatting with CSS have failed (I cannot consider editing the html file manually). Has anyone seen this on MiKTeX 26.2 on Windows? Is there a known workaround or some TeX4ht-related component I should verify? Thank you.

I would like to cite J. W. Strutt, who--to the best of my knowledge---is best known as Lord Rayleigh: https://archive.org/details/theorysound03raylgoog/page/108/mode/1up I think the name should appear as "J. W. Strutt, Baron Rayleigh" or---to facilitate looking up "Rayleigh" in a sorted list---"Rayleigh, J. W. Strutt, Baron". The latter format (also shown on archive.org) is something I don't see on a daily basis, so maybe there is a better way. This is how far I got. Since I don't think it is common to show his 'real' family name, but also it should not be abbreviated to initials, I treat it as a prefix. Mind that the extra comma in the name is something the bibliography system (biber+biblatex) will choke on, so I had to hide it. Unfortunately, simple wrapping {,} or obfuscating \char44 did not work so I ended up with this: \documentclass{article} \usepackage[ giveninits=true ]{biblatex} \usepackage[hidelinks]{hyperref} \addbibresource{main.bib} \begin{document} According to \textcite[\href{https://archive.org/details/theorysound03raylgoog/page/108/mode/1up}{p 108}]{Rayleigh1878ThSoundv2}: ``Measured by the resulting potential, a source of given magnitude, i.e. a source at which a given introduction and withdrawal of fluid takes place, is thus twice as effective when close to a rigid plane, as if it were situated in the open; and the result is ultimately the same, whether the source be concentrated in a point close to the plane, or be due to a corresponding normal motion of the surface of the plane itself.'' \printbibliography % Once more with names in a different format: \DeclareNameAlias{author}{family-given} \printbibliography[title={References with `family' name first}] \end{document} @preamble{{\newcommand{\comma}{,}}} @book{Rayleigh1878ThSoundv2, title = {The Theory of Sound}, author = {given=John William, prefix={Strutt\comma\ Baron}, family=Rayleigh}, publisher = {MacMillan \& Co., Ltd.}, date = {1896}, volume = {2}, url = {https://archive.org/details/theorysound03raylgoog} } This just doesn't feel right, but is there a better way?

I am trying to speed up the compilation of a complex project using a format file and tikz externalize. In particular I tried a setup like shown in the follwing MWE: preamble-min.tex \documentclass[a4paper,12pt]{article} \usepackage{tikz} \usepackage{pgfplots} \pgfplotsset{compat=1.18} \usetikzlibrary{external} \dump main-min.tex: \tikzset{ external/system call={% pdflatex -shell-escape -fmt=preamble-min \ -interaction=nonstopmode -jobname "\image" "\def\tikzexternalrealjob{\texsource}\input{\texsource}"% } } \tikzexternalize[prefix=tikz-cache/] \begin{document} \begin{tikzpicture} \begin{axis} \addplot+[raw gnuplot, mark=none] gnuplot { plot [-5:5] sin(x); }; \end{axis} \end{tikzpicture} \end{document} Compilation Steps: mkdir -p tikz-cache pdflatex -ini -shell-escape -jobname=preamble-min "&pdflatex preamble-min.tex" pdflatex -shell-escape -fmt=preamble-min main-min.tex The compilation stops with: !

The package xsim introduces its own counter for exercises and stores the countervalue to reuse it for the solution. I would like it to share a counter with theorems but I did not manage to make this happen. Is there a way to do this? Essentially like \newtheorem{theorem}{Theorem}[section] \newtheorem{prop}[theorem]{Proposition} share a counter

This is a followup to @cfr's wonderful answer to my previous question. I discovered that merely making a solution large enough for it to be typeset on the next page keeps the referenced page number from incrementing. However when I hover over the link to the solution's incorrect page number the popup shows the correct page number. I can't figure out what's causing this. I suspect the issue lies in the mechanism that creates the nonexistent counter, but I don't know how to go about debugging the problem. So my question is: what causes the solutions for the second and third exercises to be typeset on page 3 but have reference links displayed as page 2? MWE is identical to that from the linked answer except that \lipsum[1-4] is added to the solution of the second exercise. % Source - https://tex.stackexchange.com/a/761090 % Posted by cfr, modified by community.

Suppose I have an unfortunately long equation that must be split over multiple lines. Normally, I would split the line in two using a \split environment; however, when I inspect the resulting PDF in a screen reader (NVDA to be specific), it skips over my equation entirely. My hope was that it would be read as a single line. I have attached a minimal example below, which gives me this warning: "Package tagpdf Warning: Structure 17 has 1 kids but no parent. It is turned into an artifact. Did you stashed a structure and then didn't use it?" I am not sure what to make of this frankly. Am I doing something wrong here? % !TeX program = lualatex \DocumentMetadata{ uncompress, lang=en, tagging=on, tagging-setup={math/setup={mathml-SE,mathml-AF}, extra-modules={verbatim-mo, verbatim-af}}, pdfstandard=ua-2, pdfstandard=a-4f } \documentclass[12pt]{report} \usepackage{unicode-math} \begin{document} Here is a silly example: \begin{equation} \begin{split} 2+2\\ &=4 \end{split} \end{equation} \end{document}

I'm using q.uiver.app to make commutative diagrams for a project. There is a feature that allows for the label of an arrow to be displayed directly above it. This creates a white background for the label, which clashes visually with the background box. Here is an example of what it looks like: Here is an example of the code for the commutative diagram, using {description} to overlay the text above the arrow: \[\begin{tikzcd} Q &&& \\ & P && X \\ \\ & {X'} && Y \arrow["{\exists!h}"{description}, dashed, from=1-1, to=2-2] \arrow["p"{description}, from=1-1, to=2-4] \arrow["q"{description}, from=1-1, to=4-2] \arrow["a"{description}, from=2-2, to=2-4] \arrow["b"{description}, from=2-2, to=4-2] \arrow["f"{description}, from=2-4, to=4-4] \arrow["g"{description}, from=4-2, to=4-4] \end{tikzcd}\] I'm using a template for the project; here is what the stylesheet uses to define the lemma/proof boxes: % proofs: proof \definecolor{prooflinecolor}{RGB}{103, 103, 103} % rgba(40, 40, 40, 180) %FORMAT \definecolor{proofbgcolor}{RGB}{247, 247, 247} % rgba(40, 40, 40, 10) %FORMAT \linedbox{@proof}{Proof}{proof}{proofbgcolor}{prooflinecolor} % this numbers the proofs, so we renew the environment to prevent that; but we still allow a title, so you can do e.g. "Proof (of Theorem 1.2.3)" \def\qed{\null\nobreak\hfill\ensuremath{\blacksquare}} % qed square %FORMAT switch \blacksquare to \square for the not-filled-in version \renewenvironment{proof}[1][]{\csname @proof*\endcsname{#1}{}}{\qed\csname end@proof*\endcsname} \def\flushproof{\vspace{-\parskip}} % put this before a proof to make it flush with the result it's proving How do I make this white background transparent?

I was scrolling through reels earlier and came across a really cool animation: https://www.youtube.com/shorts/aQbq_Fpyyb4. Note: You can analyze the gif frame by frame using the method suggested by MS-SPO in the comments, or by using the website ez-gif, or by using custom python scripts. I interchangeably use ez-gif and python for these sorts of things, and in this instance used ez-gif.

I'm trying to generate texfonts.h from mimetex package. According to documentation I execute next TeX/METAFONT commands: mf "\mode=eighthre; input cmr10" # produces cmr10.83gf gftype -i cmr10.83gf > typeout Most of chars looks as expected (latin letters, capital Gamma and Theta), but capital Delta looks strange. See fragment of typeout file: 1561: beginning of char 0 .<--This pixel's lower left corner is at (0,8) in METAFONT coordinates ****** * * * * * * * * *** .<--This pixel's upper left corner is at (0,0) in METAFONT coordinates 1588: beginning of char 1 .<--This pixel's lower left corner is at (0,8) in METAFONT coordinates * * * * * ** ** * * * * * * .<--This pixel's upper left corner is at (0,0) in METAFONT coordinates 1623: beginning of char 2 .<--This pixel's lower left corner is at (1,8) in METAFONT coordinates ** * * * * * ** * * * * * * * ** .<--This pixel's upper left corner is at (1,0) in METAFONT coordinates If I repeat the same, but use mode=preview, Delta looks ok also. Whether this is sort of bug? If yes, and if I understand correctly, cmr10.mf includes roman.mf, which includes greeku.mf, where description of how to draw Δ is placed. But I can't understand syntax and unable even to determine, whether first step (mf) or second (gftype) cause error. Anyway, seems this files weren't updated recently. I have almost no knowledge about TeX fonts, just want to repeat abovementioned header file. Most of letters for cmr10.83 converted successfully (i.e. I got same hex representation), but not this Delta.

when defining a figure that holds a table of images, how do i ensure even and symmetric padding when using \hline in it? by default, there's no padding before the row that was \hlined. i have the following MRE: \documentclass{article} \usepackage{array} \usepackage{graphicx} \newcolumntype{I}{>{\centering\arraybackslash}m{0.18\linewidth}} % simulate images \newcommand{\fakeimg}{\rule{\linewidth}{2.5cm}} \begin{document} \begin{tabular}{c I I I} & A & B & C \\ row1 & \fakeimg & \fakeimg & \fakeimg \\ \hline row2 & \fakeimg & \fakeimg & \fakeimg \\ \end{tabular} \end{document} this produces the following image, where the rule is stuck tightly to the images on the second row: how do i define the padding in a controlled (tunable) manner so that the optional rule perfectly divides it in half (i want to add the divider only between specific pairs of rows)? i've tried interjecting a bunch of artifical spaces and padding in the rows before/after, but they all break apart when i wish for a small-scale padding of, say, 0.3ex: my attemps yield assymetrical padding where the padding before second row is smaller than padding after the first row.

There was this question long time ago And there was answer given by multicols creator Frank Mittelbach with code to implement at least a trivial implementation of floats. It seems that that code is not working anymore. There were changes in LaTeX a few year ago and I suppose they had caused code to brake. I'm honestly interested if there is a way to restore the code in order to get back Frank's trivial implementation of floats insede multicols columns? I am using Frank's multicol-floats.sty as given in old post.

While writing paper, I found that abnormal vertical blank space appears at the bottom of footnotes in the first column of the cas-dc template. Even after replacing the original paper content with other characters, the issue still persists, and the reproducible code provided below is just an example rather than the only scenario that triggers this problem. I am using TeX Live 2026 on the Windows system and compiling documents with pdflatex, and I aim to identify the root cause of this abnormal blank space and find corresponding methods to avoid it. \documentclass[a4paper,fleqn]{cas-dc} \begin{document} \shorttitle{} \title[mode=title]{consequat.

I'm new to luadraw and I'm trying to recreate the diagram below: Here is my code so far, and the result: % !TEX TS-program = LuaLaTeX \documentclass{standalone} \usepackage[3d]{luadraw} \begin{document} \begin{luadraw}{name=wedge} local a, b, c = 8, 6, 4 local xmax, ymax, zmax = a+1, b+1, c+1 local g = graph3d:new{ window3d = {0,xmax,0,ymax,0,zmax}, viewdir = {30,60}, size={10,10,0} } local xIntcpt, yIntcpt, zIntcpt = M(a,0,0), M(0,b,0), M(0,0,c) local P = M(4,0,0) local Q = interDD({P,vecJ},{xIntcpt,yIntcpt-xIntcpt}) local R = interDD({P,vecK},{xIntcpt,zIntcpt-xIntcpt}) g:Dscene3d( g:addPolyline({ {Origin,xmax*vecI}, {Origin,ymax*vecJ}, {Origin,zmax*vecK}, }), g:addPolyline( {xIntcpt,yIntcpt,zIntcpt}, {close=true,color="cyan"}), g:addFacet( {P,Q,R}, {color="cyan",opacity=0.5} ), g:addPolyline( {P,Q,R}, {close=true,color="cyan",style="dashed"} ), g:addLabel( "\\(x\\)",P,{pos="NW",dist=0.1}, a,xIntcpt,{pos="NW",dist=0.1}, b,yIntcpt,{pos="N",dist=0.1}, c,zIntcpt,{pos="NW",dist=0.1} ) ) g:Show() \end{luadraw} \end{document} The issue, as you can see, is that the point (0,6,0) is out of frame. I tried increasing ymax, that seems to have no effect. I tried changing the width in the size option, but that only stretches the diagram horizontally. I have tried different viewdir options, but they all cut the diagram off at one edge. I'm sure it's something basic that I'm missing, but I'm too much of a novice to notice. Any clues?

I need to align the \closing{} of the letter package with the body of the letter, on the left, while keeping the \signature{} but this code is actually removing the \signature{} from the rendered document: \documentclass[a4paper]{letter} \signature{Your Name} \address{Your Address} \date{\today} % I renew the closing command here, before beginning the document: \renewcommand{\closing}[1]{\par\noindent#1\par} \begin{document} \begin{letter}{Recipient Name \\ Recipient Address} \opening{Dear Sir or Madam,} This is the body of the letter.

When using fractions in \polylongdiv, the vertical spacing turns out rather awkward. If no fractions are used for the coefficients, the spacing is fine. I have tried to adjust the vertical spacing using arrayrowsep=..., but without any visible change. Is it possible to adjust this vertical spacing for fractions? \documentclass{article} \usepackage{polynom} \polyset{style=C,div=:,arrayrowsep=1cm} \begin{document} \polylongdiv[arrayrowsep=1cm]{(1/5)x^2-(3/7)x+4/9}{x-1/2} \polylongdiv[arrayrowsep=1cm]{5x^2-5x+6}{x-3} \end{document}

I have a working exercise/solution engine based on that from the tcolorbox documentation and it works perfectly. There is one thing I would like to change if possible. In my MWE, I create three exercises and their corresponding solutions and I also create new autorefnames for their respective counters. The exercises are in two different sections but all the solutions are in a new section and that causes the solution numbers typeset when I cite them with \autoref to reflect the new section, not the sections of the corresponding exercises. In other words, the names of the solutions to Exercise 1.1 and Exercise 2.1 typeset as Solution 3.1 and Solution 3.2 whereas I would like them to be Solution 1.1 and Solution 2.1 respectively even if they are in the third section. I think my question is: can I make a solution's number retain the value of the number of its corresponding exercise even when the solution is in a different section of the document? I have experimented and nothing I have tried works. This is for a larger book project and I can live with the situation but I want to know if my question has a relatively simple answer.

I would like to use Initials in a nice poetry book and need for German Umlaute (Ä Ö Ü) those designs. And the general question is: Why are Initials always without special characters, also for other languages other than German? And for now: How is it possible to produce Ä Ü Ö manually? \documentclass[a4paper]{article} \input Zallman.fd \pagestyle{empty} \begin{document} \begin{center} \fontsize{60pt}{72pt}\usefont{U}{Zallman}{xl}{n} ABCDE \\ FGHIJK \\ LMNOP \\ QRSTU \\ VWXYZ \\ ÄÖÜ \\%<-- Special characters Umlaute Initials?! \end{center} \vfill \begin{center} Font name: ``Zallman'' (ZallmanCaps) \end{center} \end{document} Is there a trick to get them nice?

I need all binomial coefficients for n=1..100 and k=1..100 several times, so I wrote a code with xint: \xintdefvar BinomialArray = ndseq(binomial(n,k), n=1..100; k=1..100); \xintdeffunc abinomial(n,k):=BinomialArray[n-1,k-1]; I measured out for that: ******************************************** *** TOTAL COMPILATION TIME REPORT: *** (l3benchmark) + TOC: 2.27 s ******************************************** This is OK, but I asked myself: Is there any way I can store the array (in a file?) so that it doesn't have to be recalculated on every new run? \documentclass[paper=a5, paper=landscape]{scrarticle} \usepackage[margin=10mm]{geometry} \usepackage{xintexpr} \usepackage{amsmath} \begin{document} \xintdefvar BinomialArray = ndseq(binomial(n,k), n=1..100; k=1..100); \xintdeffunc abinomial(n,k):=BinomialArray[n-1,k-1]; %Test: \xinteval{BinomialArray[100-1,50-1]} works Test: $\dbinom{100}{50}=\xinteval{abinomial(100, 50)}$ % Show complete array - on your own risk :() %\newpage %\begingroup %\tiny %BinomialArray = \xintthealign\xintexpr BinomialArray\relax %\endgroup \end{document}

As what my knowledge could tell, It's possible to create a triangle with only 2 coordinates to make real angles to be exact, and using path to create long rays and naming the intersection of those rays and finally connect them with \draw. MWE: \documentclass[tikz, border=10pt]{standalone} \usepackage{siunitx} \usetikzlibrary{intersections} \begin{document} \begin{tikzpicture}[scale=2] \clip (0,0) rectangle (5,2.1); \coordinate (A) at (0,0); \coordinate (C) at (5,0); \path[name path=AB] (A) -- ++(37:4); \path[name path=BC] (C) -- ++(137:4); \path[name intersections={of=AB and BC, by=B}]; \draw[thick] (A) -- (B) -- (C) -- cycle; \end{tikzpicture} \end{document} There is a noticable difference if I comment \clip in the 6th line. Without it, it's going to be a white space... It's impractical to calculate the height of the object if I make another drawing with more complicated shape. So, is it possible to autocrop the exceeding lines? What I meant by exceeding lines is like the cyan lines in the figure below. It's because they contribute to white space if I change \draw to \path: So, if possible, I want TikZ to automate cropping the intersection, in other words, getting rid of those exceeding lines without estimating like how much the height is (would consume loads of time if I make other complicated figures with intersections). To illustrate what I actually want, roughly I want something like this: Yes, I deliberately cropped it poorly to give an example as to what it shows if I gave them an incorrect clipping, which I wish I didn't need to clip it, but instead, I wish TikZ only read the intersection point and two given coordinates to draw.

I am creating an accessible PDF using tagpdf as follows: \DocumentMetadata{ lang = fr-FR, pdfversion = 2.0, pdfstandard = ua-2, pdfstandard = a-4f, %or a-4 tagging = on, tagging-setup={math/setup=mathml-SE} } \documentclass[a4paper,11pt]{article} % Page layout \usepackage[margin=2.5cm]{geometry} \usepackage{pdfpages} % General information \author[]{YamiOmar88} \title{Some Title} \date{} % remove semantic paragraphs: \AssignTaggingSocketPlug{para/semantic/begin}{noop} \AssignTaggingSocketPlug{para/semantic/end}{noop} \begin{document} % --- Poster pages (NOT accessible, marked as artifacts) --- \tagstructbegin{tag=Artifact, alt={Tableau de bord non accessible}} \includepdf[pages=1, fitpaper=true, artifact]{example-image.pdf} \includepdf[pages=1, fitpaper=true, artifact]{example-image.pdf} \tagstructend \end{document} I include pages from another PDF file using the pdfpages package and the command \includepdf. Here, for this example I'm always including the same page #1 and using a sample image to be able to compile it. When I look at my tags I see this: <Document> <Private> <Figure> <p> <Figure> <p> As I declared the artifact, the <Private> tag shows the appropriate alt-text. However, the <Figure> tags contain the path to the image as alt text. How can I change that? I do not want that path to be made public. And what are the <p> tags? Where did they come from?
