I am looking for guidance on how to recreate the attached image (image.png) entirely within LaTeX using TikZ. The image consists of two main complex elements: A red ribbon with intricate curves and realistic 3D-like gradient shading. A multi-faceted jewel/diamond in the center with sharp light reflections. Initially, I thought simulating this 3D effect in TikZ would be too complex, but following the community's helpful feedback and advice on providing a Minimal Working Example (MWE), I decided to tackle both the ribbon and the central jewel to demonstrate my progress. I managed to draw the ribbons using manual Bézier curves and custom shadings to simulate the folds. For the jewel, I used a clipping mask and layered semi-transparent polygons (opacity) to mimic the glass facets and light reflections. Here is my current MWE: \documentclass[tikz,border=5mm]{standalone} \usetikzlibrary{shadings,calc} \definecolor{ribbonred}{RGB}{215,10,28} \begin{document} \begin{tikzpicture}[x=3cm,y=3cm] \begin{scope} \fill[% top color=ribbonred!20!black, bottom color=ribbonred!20!black, middle color=ribbonred, shading angle=150] (-0.463,-0.006) .. controls (-0.497,-0.017) and (-0.649,-0.048) ..

Additionally, I really struggled with color coordination and picking the right shades for the gradients. If anyone could help me adjust the color palette to make the ribbon look more naturally glossy and realistic, I would be very grateful. I also want to thank kabenyuk for their excellent answer which showed how to modularize the ribbon drawing! Any further improvements or tips on combining these elements effectively would be greatly appreciated.

I want to get a oneside document, whose everypage holds left margin region as below: The target sketch above was the second page given by: \documentclass{book} \usepackage[ showframe, includemp, textwidth=12cm, marginparsep=0.5cm, marginparwidth=5cm, ]{geometry} \usepackage{amsmath} \usepackage{lipsum} \begin{document} \section{Test Test Test Test} \lipsum[1-3] \lipsum[1][1]\marginpar{\raggedright\lipsum[2][1-4]}\lipsum[2-3] \section{Test Test Test Test} \lipsum[1-3] \lipsum[1][1]\marginpar{\raggedright\lipsum[2][1-4]}\lipsum[2-3] \end{document} Now, I want to fix the geometry paramters, change to oneside, and add \reversemarginpar: \documentclass[oneside]{book} \usepackage[ showframe, includemp, textwidth=12cm, marginparsep=0.5cm, marginparwidth=5cm, ]{geometry} \usepackage{amsmath} \usepackage{libertinus-otf} \usepackage{lipsum} \reversemarginpar \begin{document} \section{Test Test Test Test} \lipsum[1-3] \lipsum[1][1]\marginpar{\raggedright\lipsum[2][1-4]}\lipsum[2-3] \section{Test Test Test Test} \lipsum[1-3] \lipsum[1][1]\marginpar{\raggedright\lipsum[2][1-4]}\lipsum[2-3] \end{document} The result was unexpected: My question is that, in my ideal "left margin region" oneside document, the settings: \usepackage[ showframe, includemp, textwidth=12cm, marginparsep=0.5cm, marginparwidth=5cm, ]{geometry} was enough to reverse the margin, I don't want to manually calculate something like left=? within geometry setting. I wonder how to get a "oneside" document with reversed "left margin region" everypage without specifying/calculating parameters other than textwidth=12cm,marginparsep=0.5cm,marginparwidth=5cm.

How can you obtain automatically all the available fonts in "https://ctan.org/pkg/lua-unicode-math" ( https://ctan.org/pkg/lua-unicode-math )

I made the following diagram, which is supposed to depict how the intersection of two intervals can be determined. However, as you can see, I could include only one number line, which makes the diagram look rather empty, in my opinion. Is there a away to draw two more number lines above the original one, aligned with the "flying" blue intervals? I have thought about drawing three separate tikz pictures above each other, but then I can't draw the red dashed line, and it would also make it difficult to control the invisible space taken by the y-axis. \documentclass{book} \usepackage{pgfplots} \begin{document} \begin{tikzpicture}[every node/.style={font=\small},] \begin{axis}[ clip=false, axis x line=middle, axis y line=none, x axis line style={<->}, xmin=-3.4, xmax=7.4, ymin=-.5, ymax=3, xtick distance=1, x=.6cm, y=1cm, ] % Red dashed lines \draw [red,dashed] (axis cs:-1,0) -- (axis cs:-1,2.2) (axis cs:6,0) -- (axis cs:6,2.2); % Points \addplot[only marks,mark options={fill=white}] coordinates {(6,2) (-1,1) (6,0) (-1,0)}; % Uppermost number line for x < 6 \draw[<-,very thick] (axis cs:-3,2) -- (axis cs:6,2); % Middle number line for x > -1 \draw[->,very thick] (axis cs:-1,1) -- (axis cs:7,1); % Lower number line for intersection of inequalities \draw[very thick] (axis cs:-1,0) -- (axis cs:6,0); % Labels \draw (axis cs:8,2) node[right]{$x<6$} (axis cs:8,1) node[right]{$x>-1$} (axis cs:8,0) node[right]{$x<6$ and $x>-1$, or simply $-1<x<6$.}; \end{axis} \end{tikzpicture} \end{document} Here is what it looks like (note I have removed color and font information from the code to keep things simple).

The LaTeX format has recently implemented templates for block environments, lists, and headings. Is there a collection of examples of using these templates for document design? (I'm only aware of the examples for ltx-talk.) It's not easy to search for "examples of LaTeX templates" online -- the wrong stuff comes up! Addendum: the ltx-talk examples are here.

How can I format the derivative of a long vector function in LaTeX so it does not spill over the page margin? Is it better to stack the components in a column, use line breaks with hanging indents inside parentheses, or break it down component by component? \documentclass{article} \usepackage{mathtools} \usepackage{unicode-math} \begin{document} \begin{align*} \frac{d}{dt}\biggl( \frac{2at^2}{t^2+1}, \frac{2at^3}{t^2+1}, \frac{2at^4}{t^2+1} \biggr) &=\biggl( \frac{d}{dt}[2at^2](1+t^2)^{-1}+\frac{d}{dt}[(1+t^2)^{-1}](2at^2), \frac{d}{dt}[2at^3](1+t^2)^{-1}+\frac{d}{dt}[(1+t^2)^{-1}](2at^3), \frac{d}{dt}[2at^4](1+t^2)^{-1}+\frac{d}{dt}[(1+t^2)^{-1}](2at^4) \biggr) \end{align*} \end{document}

Does plain TikZ have a built-in way to reuse intermediate mathematical calculations across plot dimensions? I mean I could just use a foreach loop and pgfmathsetmacro, but that's quite intensive. Is this built in to plot? If not, should/could it be? I mean, I doubt it, but I also doubted that my previous question had a good solution - which I, to my pleasant surprise, turned out to be wrong about. % Source - https://tex.stackexchange.com/a/764941 % Posted by kabenyuk, modified (!) by Jasper.

How to obtain (a list) all the fonts installed in the TeX installation and in the system. Similar to https://tug.org/FontCatalogue/alphfonts.html but better in PDF pages.

I would like to break between pages an align* environment, yet it does not work. I use \tcbsetforeverylayer[breakable] so that all nested tcolorbox environment that I use can break between pages and \allowdisplaybreaks for breaking align* environment in pages. When I try to put an align* environment in my theorem (or leftrule) environment, it breaks between pages. But if I put nested environments, it does not anymore and I get the following warning : Package tcolorbox Warning: The upper box part has become overfull Here is my (maybe not minimal) source code : \documentclass[11pt]{scrbook} \usepackage{amsmath,amsfonts, amsthm, graphicx} \usepackage[margin=1.5cm,bottom=3cm, top=3cm]{geometry} \allowdisplaybreaks \usepackage{tikz} \usepackage[most]{tcolorbox} \tcbsetforeverylayer{enhanced,breakable} \newenvironment{leftrule}{ \begin{tcolorbox}[frame hidden, boxrule=0pt, borderline west={2pt}{0pt}{black}, opacityback=0] } { \end{tcolorbox} } \title{} \author{} \date{} \begin{document} \maketitle \begin{leftrule} \begin{leftrule} \begin{align*} &= b \\ &= b \\ &= b \\ &= b \\ &= b \\ &= b \\ &= b \\ &= b \\ &= b \\ &= b \\ &= b \\ &= b \\ &= b \\ &= b \\ &= b \\ &= b \\ &= b \\ &= b \\ &= b \\ &= b \\ &= b \\ &= b \\ &= b \\ &= b \\ &= b \\ &= b \\ &= b \\ &= b \\ &= b \\ &= b \\ &= b \\ &= b \\ &= b \\ &= b \\ &= b \\ &= b \\ &= b \\ &= b \\ &= b \\ &= b \\ &= b \\ &= b \\ &= b \\ &= b \\ &= b \\ &= b \\ &= b \\ &= b \\ &= b \\ &= b \\ &= b \\ &= b \\ &= c \end{align*} \end{leftrule} \end{leftrule} \end{document}

I am working on a document where I created a custom page border and headers/footers using TikZ and eso-pic. However, the document is extremely heavy to process. The compilation time is very slow, and it gets significantly worse as the number of pages increases. Is there a more efficient way to write this code? For example, is there a way to render the background only once and reuse it across all pages (like saving it to a box), instead of drawing these complex paths and loops on every single page?

Also, I am using some local Arabic fonts in my code (Aljazeera.ttf and Al Qalam Quran Majeed Web.ttf). If you want to test the code on your machine, you can simply comment them out or replace them with any standard font (like Amiri). My main problem is that compiling this document is extremely slow because of the complex TikZ background (especially the loops and smooth paths). The processing time gets heavier and heavier with every new page added. Is there a way to optimize this? For example, is it possible to render this background only once (saving it into a box) and reuse it on every page to drastically reduce the compilation time? Any help or optimized code would be highly appreciated. Thank you! EDIT/UPDATE: I sincerely apologize for my previous code. I realized it contained local Arabic fonts and packages (polyglossia) which made it impossible for you to compile and test. I have completely cleaned up the code. It is now a proper Minimal Working Example (MWE) using only standard packages and example-image. My issue is that this document is extremely slow to compile because of the complex TikZ background (the loops, \whiledo, and smooth curves). The compilation time increases heavily with every new page. As pointed out in the comments, I need to separate the static parts (the complex borders/decorations) from the variable parts (like the page number), but my code is too entangled with nested tikzpictures and tcolorbox. Could someone please provide a structural example of how to redesign this so the heavy background is drawn/saved only once, drastically reducing compilation time?

I am typesetting a Dutch text in lualatex / polyglossia. All hyphenation instances occur correctly, but one: Nederlands-Indië, which I coded as Nederlands\hyp{}In\-dië, in order to preserve the dash and to encourage hyphenation between n-d. Correct hyphenations are: Neder- lands-Indië Ne- derlands-Indië Nederlands- Indië Nederlands-In- dië. Note that in all these cases the dash remains. However, in my text it is occasionally also hyphenated as: Nederlands-Indi- e. This is incorrect and ugly typesetting, because of the single e on the new line. It is probably caused by the fact words containing an ë (e-trema) are hyphenated, e.g. in the case of geënt, ë indicates a new syllable. Therefore ge- ent is correct. I tried settings like these, \lefthyphenmin=3 \righthyphenmin=3 \hyphenpenalty=500 but the problem persists. Has anyone a solution?

I'd like to have a bibliography per chapter using biblatex, along with a final, global bibliography at the end.

First of all, the first bibliography contains backreferences to the second chapter. This is not dramatic, though if possible I'd rather not having this, but more importantly may be linked to the second problem, which is that the hyperlink [Doe25] in the second chapter sends to the first bibliography. Is there a way for the hyperlink to send the reader to the current chapter's bibliography? Note that I've also tried to add the method described in this post by adding backend=biber adding natbib=true removing the segment=\therefsegment adding the relevant piece of LaTeX3 code which resulted in the following code: \documentclass[a4paper, 11pt]{book} \usepackage[english]{babel} \usepackage[% sorting=nty,% style=alphabetic,% backref=true,% refsegment=chapter,% isbn=false,% backend=biber, natbib=true, ]{biblatex} \usepackage{csquotes} % Recommended by biblatex \addbibresource{main.bib} \usepackage{xparse} \ExplSyntaxOn \seq_new:N\g_UF_allcitekeys_seq \AtEveryBibitem { \seq_gput_right:Nx\g_UF_allcitekeys_seq{ \thefield{entrykey} } } \NewDocumentCommand\nociteall { } { \seq_map_function:NN\g_UF_allcitekeys_seq\nocite } \ExplSyntaxOff \makeatletter %for the backrefs of the main bib: \let\oriabx@aux@backref\abx@aux@backref \renewcommand\abx@aux@backref[5]{% \oriabx@aux@backref{#1}{#2}{#3}{#4}{#5}% \oriabx@aux@backref{#1}{#2}{0}{#4}{#5} } \makeatother % Hyperlinks \usepackage[linktocpage=true]{hyperref} \begin{document} \chapter{First chapter} Let's cite \cite{AN25} here. \printbibliography[segment=\therefsegment,heading=subbibliography] \selectlanguage{english} \chapter{Second chapter} Let's also cite \cite{AN25} here. \printbibliography[segment=\therefsegment,heading=subbibliography] \appendix \printbibliography \end{document} but both issues persist.

I have a fairly complex document, but I extracted this MWE from it. I'm including a similar file tree as what's in the actual document to ensure that its as close to my document as possible. For extra context, I am using Overleaf, and compiling using LuaLaTeX (in case that's relevant). main.tex has this: \documentclass{article} \usepackage{standalone} \usepackage{hyperref} \begin{document} \input{Chapter1} \end{document} The content of Chapter1.tex is as follows: \input{Images/Chapter 1/Tester} and the Tester.tex file referenced is as follows: \documentclass{standalone} \usepackage{tikz} \usepackage{adjustbox} \begin{document} \begin{adjustbox}{margin=2} \begin{tikzpicture} \node [draw,circle,black,scale=0.7,minimum width=46] at (0,0) {Tester}; \end{tikzpicture} \end{adjustbox} \end{document} I should note that when I compile Tester.tex, it generates the circle fine. When I compile main.tex, however, it gives me the line of code itself in the pdf: I was using the standalone package as suggested in the answers to this question, but it was not enough. Any advice is appreciated!

How can I handle division by zero and non-Euclidean distortions in Asymptote without erroring? My goal is to illustrate point-at-infinity illustrations. For example, try setting MAIN_PARAMETER to 180, which is a full inversion, and I cannot achieve it due to the error.

I'm trying to rewrite the Minimal Working Example (MWE) below to: Use \pctitleformats{part}{blue} instead of \pctitleformats{\part}{part}{blue} Add \partmark{#1}|\chaptermark{#1}. The working reference without auxiliary commands is the following: \titleformat{\part}{\partmark{#1}\Huge\bfseries\color{blue}}{\thepart}{10pt}{#1} \titleformat{\chapter}{\chaptermark{#1}\Huge\bfseries\color{green}}{\thechapter}{10pt}{#1} The naive solution with helper commands is the following: \newcommand*\pctitleformat[4][]{ \titleformat{name=#2, #1}[hang]{\filcenter\bfseries\Huge\color{#4}}{}{0pt}{#3##1} } \newcommand*\pctitleformats[3]{ \pctitleformat{#1}{#2~$|$~}{#3} \pctitleformat[numberless]{#1}{}{#3} } \pctitleformats{\part}{\thepart}{blue} \pctitleformats{\chapter}{\thechapter}{green} However, it is lacking the \*mark{#1}, which the reference has.

I have noticed that when using the TeX Gyre Termes Math font, the spacing is too small. As you can see below, the letter j is practically jammed into the absolute value bars, as well as the ordinary square and round brackets. Is this the expected behavior of the font? If yes, is there a way to fix it? MWE: \documentclass{book} \usepackage{unicode-math} \setmainfont{TeX Gyre Termes}[Scale=1] \setmathfont{TeX Gyre Termes Math}[Scale=1] \begin{document} \[ \lvert j^2 - 1 \rvert \] \[ [j^2+1] \] \[ (j^2+1) \] \end{document}

I have the following question. I have been looking in other places and I can't find anything similar (or I don't know how to look for it). I want to make a table with two columns and one row, so that I can buy a text in medieval Catalan and the Latin translation. I had thought about making a table, but I have a problem. The columns go beyond the page and, then, they appear cut off and do not continue on another page (as would happen with Word). Is there any way to make this document look like the one in Word that I am attaching? Thank you very much This is my code: \documentclass[12pt,a4paper]{article} \usepackage[utf8]{inputenc} \usepackage{longtable} \usepackage{lipsum} \begin{document} \lipsum[1] \begin{longtable}{|p{0.47\textwidth}|p{0.47\textwidth}|} \hline \lipsum[1] \par \lipsum[1] \par \lipsum[1] \par \lipsum[1] & \lipsum[1] \par \lipsum[1] \par \lipsum[1] \par \lipsum[1] \par \end{longtable} \lipsum[1-2] \end{document}

I was making a rational double pendulum in Asymptote: // a rational double pendulum import graph; unitsize(3cm); pair truncated_pi(real t) { real t1 = 3.14 * t; return ( cos(t) + cos(t1), sin(t) + sin(t1) ); } path f = graph(truncated_pi, 0, 314, n=10000); draw(f); I wanted to make it in TikZ, but I am running into the issue of needing a number of samples which is beyond the limit imposed by pgfmath. As some of you may be familiar with, I am very fond of plain TikZ. I would like to see if there are ways to achieve this which are not overly ad hoc. For example, one strategy would be to break the domain into separate regions. How would one draw something like this in the spirit of plain TikZ? \documentclass[tikz]{standalone} \begin{document} \begin{tikzpicture} \draw[ domain=0:314, samples=10000, trig format=rad, declare function={ t1(\x) = 3.14 * \x; x(\x) = cos(\x) + cos(t1(\x)); y(\x) = sin(\x) + sin(t1(\x)); } ] plot ({x(\x)},{y(\x)}); \end{tikzpicture} \end{document}

Is there a way to change the kinds of words that the word repetition checker looks for? I like that it will help add variety (e.g. the overuse of very) and find any accidental duplicated words (e.g. "the the tree...") but function words like articles and prepositions can naturally occur frequently (e.g. "the first of the two options..." or "the crown of the king of England"). I dislike seeing the indication that I have a supposed error, and while some can be avoided, not all can be. Is there a way to fix this or is this just something I will have to learn to ignore? It makes me second guess myself unnecessarily.

I am currently writing a linguistic document for which I will need to include multiple tables showing the inflection of various classes of word. I want to be able to have multiple noun declension tables, adjective declension tables, and verb inflection tables throughout the document, and for each table of a given type to have corresponding columns with the same widths (if I overlay one table of a given type over another, the column edges should line up). I.e. I have tables belonging to three types, A, B, & C. Each table of a given type has the same number of rows and columns. I want to ensure that each table of a given type is rendered with the same column widths (ideally this would not have to be set manually by me, but determined based on the widest text placed in a given column in a table of that type). The different types of tables may be interspersed with each other, and tables of a given type might occur in different chapters, so any solution would need to be able to handle that. A minimum example: \documentclass{article} \setlength\parindent{0pt} \begin{document} \begin{tabular}{ r l l} Case & Singular & Plural \\ \hline Nominative & -foo & -bar \\ Accusative & -foo & -bar \\ Genitive & -foo & -bar \\ \end{tabular}\\ Lorem ipsum dolor sit amet, consectetur adipiscing elit. Aenean dictum, mauris id cursus interdum, ligula libero tristique nisi, eget accumsan risus diam et erat. Nulla dignissim neque a accumsan tincidunt. Integer eleifend vel ante porta fringilla. Praesent et venenatis enim, eget vehicula lorem. Curabitur cursus condimentum sagittis. Curabitur eget facilisis massa. Phasellus vitae scelerisque neque. Pellentesque quis magna sed neque mattis tincidunt.\\ \begin{tabular}{ r l l l l l l} Tense & 1sg & 2sg & 3sg & 1pl & 2pl & 3pl \\ \hline Present & -foo & -foo & -foo & -bar & -bar & -bar \\ Past & -foo & -foo & -foo & -bar & -bar & -bar \\ Future & -foo & -foo & -foo & -bar & -bar & -bar \\ \end{tabular}\\ Donec vitae risus id eros consectetur gravida eget nec erat. Fusce condimentum, sapien id vulputate ultricies, felis lacus sagittis elit, sit amet accumsan purus ante dapibus magna. Cras nec quam ac diam dapibus elementum sit amet vitae turpis. Praesent bibendum eleifend imperdiet. Etiam sit amet congue libero. Donec at mauris vitae mi tristique rhoncus sit amet sed turpis. Phasellus sed velit nec sem sodales molestie. Ut gravida, lorem at euismod elementum, lectus massa viverra dui, a ultrices arcu nulla nec arcu. \\ \begin{tabular}{ r l l} Case & Singular & Plural \\ \hline Nominative & -a-really-long-ending & -bar \\ Accusative & -foo & -bar \\ Genitive & -foo & -bar \\ \end{tabular}\\ Lorem ipsum dolor sit amet, consectetur adipiscing elit. Aenean dictum, mauris id cursus interdum, ligula libero tristique nisi, eget accumsan risus diam et erat. Nulla dignissim neque a accumsan tincidunt. Integer eleifend vel ante porta fringilla. Praesent et venenatis enim, eget vehicula lorem. Curabitur cursus condimentum sagittis. Curabitur eget facilisis massa. Phasellus vitae scelerisque neque. Pellentesque quis magna sed neque mattis tincidunt.\\ \begin{tabular}{ r l l l l l l} Tense & 1sg & 2sg & 3sg & 1pl & 2pl & 3pl \\ \hline Present & -foo & -foo & -foo & -bar & -bar & -bar \\ Past & -foo & -foo & -something-that's long & -bar & -bar & -bar \\ Future & -foo & -foo & -foo & -bar & -bar & -bar \\ \end{tabular}\\ \end{document} The first and third table are of the same type, and the second & fourth table are of the same type. Because of this, the two Singular columns of the first and third tables should be of the same width, but because the third table has a longer ending in the table, its Singular column is much longer. Likewise, the 3sg columns of the second and third tables should have the same width, but in the fourth table it's much wider. As seen here, tables of a given type may be separated by other tables (including other tables of a repeating type). There might also be chapter/section/subsection boundaries between the tables of a given type.

I have a .tex file that used to compile (here is the full file), but since an upgrade of my Debian system, which I assume pulled in some new version of LaTeX packages, it fails to build with this error when I run xelatex on it: ! LaTeX Error: Command \scr@tso@lstlisting@linefill undefined. That looks like some internal issue in koma-script/tocbasic.sty, but my understanding of LaTeX isn't enough to know what to do about it. That sty file looks like it checks for this command being undefined and then defines it, yet here I am with the error. I'd be grateful for a proper solution, of course, but also satisfied with a crude hack to suppress this error so that my pdf file builds again. Edit: This is a minimal reproduction. Seems that both listings and arabxetex have to be present to trigger the error. \documentclass{scrbook} \usepackage{listings} \usepackage{arabxetex} \begin{document} \end{document} Further edit: The suggested fix of adding a line like this... \makeatletter \def\scr@tso@lstlisting@linefill{} \def\scr@tso@lstlisting@pagenumberformat#1{} \makeatother ... avoids this issue, but somehow affects pdfpages in a way that breaks \includepdf.

I wrote my question in a comment within the following Asymptote code. My goal is to do a matrix multiplication (rotation, Rodriguez) on a sphere I made in Asymptote, without changing the camera. Rodriguez rotation is angle by axis, as opposed to Euler, which is by standard axes in a specific order. Also, any explanation as to why this is rather slow? I think it would be even clearer to pose this as a multiplication on an arbitrary triple. import three; unitsize(5cm); currentprojection=orthographic(1,2,3); /* draw((0,0) -- (1,1)); label("\(a\)", (0,1), (-1,-1)); draw((0,0)..controls (0,1) and (1,1)..(1,0)); */ triple SP(triple point){ return ( point.x / (1 - point.z), point.y / (1 - point.z), 0 ); } triple ISP(triple point){ real temp = point.x^2 + point.y^2; return ( 2 * point.x / (1 + temp), 2 * point.y / (1 + temp), (-1 + temp) / (1 + temp) ); } for(int i=-10; i<=10; ++i){ for(real j=-10; j<=10; j += 0.1){ if(j!=10){ draw(ISP((i,j,0)) -- ISP((i,j+1/10,0))); draw(ISP((j,i,0)) -- ISP((j+1/10,i,0))); /* My motivation in asking this question is to perform a general axis-angle (Rodriguez) transformation to this Riemann sphere, without changing the camera projection. I want to use a matrix multiplication, hopefully through a build in method with operator overloading and everything. */ } } }
