This would cause the 1 in the vector to become a non-1 value. To restore it to 1, \textbf{we divide every component, including itself, by it}. How could I illustrate the last step, if that number were some number $n$? \[ \begin{bmatrix} b & t \\ n & 1 \end{bmatrix} \begin{bmatrix} a \\ 1 \end{bmatrix} = \projectivestep \begin{bmatrix} t+ab \\ na+1 \end{bmatrix} = \begin{bmatrix} \frac{t+ab}{na+1} \\ 1 \end{bmatrix} \] The answer should be the exact same as above, but with one more illustration, showing how the projective step transforms the line. The reason I am having difficulty is because it maps every point differently. That is, points in one direction become closer together, and they become further apart in the other direction. \end{document}

The Problem From cfr's answer to my previous question, I managed to draw nice vdots in my forest tree. But now for tree={ s sep=1cm, % example of 1cm for illustrative purposes; you probably wouldn't want it to be so big l sep=1cm }, fails to be applied across the entire tree: Attempt(s) To Fix Said Problem I tried messing with before computing xy={% l'=0pt, s'=-15pt, % length of vdots }, but it didn't really work. What Help I need I've only had very modest experience with forest so I'm having trouble deducing how to modifiy cfr's code, such that the keyvals s sep and l sep work correctly. Thus, it would be nice if someone was able to help me out with this. MWE: % Source - https://tex.stackexchange.com/a/755401 % Posted by cfr, modified by community.

This is my first question here; please let me know if anything is missing. I am trying to center an interlinear gloss produced with the expex package. The center environment works correctly for normal text, but it has no effect on the gloss created with \begingl … \endgl. Here is a minimal working example: %!TEX program = xelatex \documentclass[12pt]{article} \usepackage{expex} \begin{document} \begin{center} vṛndāyai tulasī-devyai priyāyai keśavasya ca viṣṇu-bhakti-prade devī satyavatyai namo namaḥ \begingl \gla keśavasya ca // \glb {to Lord Keśava} and // \endgl \end{center} \end{document} I compile this using latexmk with the xelatex engine. The first two lines are centered correctly, but the gloss remains left-aligned. I would like the gloss to be centered in the same way as the text above it. How can I center an expex gloss so it looks similar to the lines above it? Here is the resulting output:

Consider the code: \documentclass{book} \usepackage{xcolor,graphicx,comment} \usepackage[abs]{overpic} \usepackage{tikz} \definecolor{cadmiumgreen}{rgb}{0.0, 0.42, 0.235} % 0, 107, 60 \definecolor{Gold}{RGB}{228,168,73} \usepackage{transparent} \begin{document} \thispagestyle{empty} \begin{center} \begin{tikzpicture} \clip (0,0) ellipse (4.25cm and 5.5cm); \draw[line width=5pt,Gold,fill=cadmiumgreen] ellipse (4.25cm and 5.5cm); \node at (0,0) {\includegraphics[scale=.37,clip, trim = 0 0 0 0]{example-image-a}}; \draw[line width=12pt,Gold!70!black] ellipse (4.25cm and 5.5cm); \end{tikzpicture} \end{center} \begin{comment} \begin{center} \begin{tikzpicture} \clip (0,0) ellipse (4.25cm and 5.5cm); \draw[line width=5pt,Gold,fill=cadmiumgreen] ellipse (4.25cm and 5.5cm); \node at (0,0) {\includegraphics[scale=.37,clip, trim = 0 0 0 0]{example-image-a}\llap{\texttransparent{0.5}{\color{blue!35}}}}; \draw[line width=12pt,Gold!70!black] ellipse (4.25cm and 5.5cm); \end{tikzpicture} \end{center} \end{comment} \begin{figure} [!htb] \centering \includegraphics[width=8em,height=11em]{example-image}\llap{\texttransparent{0.5}{\color{blue!35}\rule{8em}{11em}}} \end{figure} \end{document} which produces the output: Now, I would like to add a visible (bluish) transparent effect to the first (green oval) image. However, when I try to incorporate the effect shown in the second image into the first, nothing seems to happen; that is, when I run the MWE with the \begin{comment}, \end{comment} taken out---nothing seems to happen. QUESTION: How may I add a transparent (blueish in this case) effect to the first (oval) image? Thank you.

I modified cfr's previous answer to draw three evenly spaced vertical dots. A sketch of the desired look is as follows, where the blue line is imaginary (only there for illustrative purposes) and should not be actually drawn by TikZ. But, only one set of my custom vdots are drawn by TikZ. Any idea how to fix this? I tried appending the node names (e.g. (A)) with a counter ((A \the<counter_name>)) that is incremented with each invocation of vdots. But that didn't seem to work at all.

I am using the metre package for metrical notation of Latin text. Here is my MWE: \documentclass[12pt]{article} \usepackage{metre} \begin{document} \begin{metrica} \=a \={ae} \-a \-{ae} \end{metrica} \end{document} This produces: The ā and ă are fine, but as you can see, with both of the "ae"s, the diacritics don't stretch to fill the whole width of the letters. Is it possible to change this so that the symbol matches the width of however many letters are under it? I would like it to work for not just 2 letters, but ideally as many as possible, e.g. I want to be able to draw a macron or even a breve over "huius" when I mark it as being one single syllable and the diacritic should then stretch to be as wide as it has to be to cover the whole word. Thanks in advance!

Consider the following example: \documentclass{article} % \usepackage{kpfonts-otf} \usepackage{unicode-math} \setmathfont{KpMath-Regular.otf} % \setmathfont{texgyrepagella-math.otf}[range={\prime}] \begin{document} \( E^{E'}_{E'} \) \( E' \) \end{document} The prime symbol in the subscript is clearly in the wrong position: I tried to replace this symbol by, say, \setmathfont{texgyrepagella-math.otf}[range={\prime}], but instead of replacing the symbol from another font, it makes the situation worse: Is there any way to fix this behavior, or at least be able to replace this symbol from another font for which the display is correct? (Perhaps other than contacting the author of kpfonts-otf, as he is quite busy recently...)

I would like to be able to display in my text a range of values with the associated unit, for example 50-200 μm: I found well how to write"50 to 200 µm" (\qtyrange[range-units = single]{50}{200}{\micro\m}) or "50-200" (\numrange[range-phrase = --]{5}{200}) but nothing to make a mix of 2.

I want to plot something as below in an elegant appraoch, with a handy control of the angle and eccentricity: (the pattern is not important here) Here below, I make some calculations: \documentclass[tikz,border=5pt]{standalone} \begin{document} \begin{tikzpicture}[line join=round] \def\R{5} \def\ell{0.9} \def\startAngle{40} \def\endAngle{90-\startAngle} \def\rhoo{\fpeval{\R*sind(45-\startAngle)/cosd(\startAngle)}} \def\Rx{\fpeval{\rhoo*(sqrt(1-(\ell^2*cosd(\startAngle)^2)))/(sqrt(1-\ell^2))}} \def\Ry{\fpeval{\Rx*(sqrt(1-\ell^2))}} \def\ellstartAngle{\fpeval{atand(\Rx/\Ry*tand(\startAngle))}} \filldraw[ fill=cyan!30, draw=cyan, very thick ] (\R,0) arc[start angle=0, end angle=\startAngle, radius=\R] { [rotate=-\startAngle] arc[start angle=-\ellstartAngle,end angle=180+\ellstartAngle,x radius=\Rx,y radius=\Ry] } arc[start angle=\endAngle, end angle=90, radius=\R] -- (0,\R) -- (\R,\R) -- cycle; \end{tikzpicture} \end{document} But it gives some drawbacks of the ellipse's ending tip: With the following sketch: My calculation thoughts is as below: noted that \StartAngle is \theta, and \ell is the ellipse's eccentricity with \def\rhoo{\fpeval{\R*sind(45-\startAngle)/cosd(\startAngle)}}, I want to derive the radius from origin of the ellipse, that is the \rho's distance in the sketch with the formula of the radius length from origin of the ellipse, that is: I want to derive the x-radius of ellipse, that is a(\Rx) via \def\Rx{\fpeval{\rhoo*(sqrt(1-(\ell^2*cosd(\startAngle)^2)))/(sqrt(1-\ell^2))}} Then I calaulated the y-radius with \Rx and \ell via \def\Ry{\fpeval{\Rx*(sqrt(1-\ell^2))}} Finally, I calculate the geometric angle of sub-path rotation learning from this answer via \def\ellstartAngle{\fpeval{atand(\Rx/\Ry*tand(\startAngle))}} I really have no idea of any mathematical calculation issues or just my tikz's parameter misunderstandings. Could somebosy give me a hand? (Any approach with neat syntax are all welcome! My calculation above is just to draw this in one \path)

I am using the chemnum package together with chemstyle to label compounds in reaction schemes. By default, chemnum only provides a single global counter (cmpdmain), so compounds are numbered like: 1, 2, 3a, 3b, 4 … However, I need multiple independent numbering series, for example: literature compounds -> 1, 2, 3… target compounds -> T1, T2… intermediates -> INT1, INT2… supplementary information -> S1, S2… So effectively I want arbitrary named numbering series: \seriesBegin{EG} \replacecmpd{a} \seriesEnd \seriesBegin{INT} \replacecmpd{b} \seriesEnd and each series should continue later in the document without resetting. What I already found This answer provides a clever workaround for two parallel numbering series by saving and restoring cmpdmain: https://tex.stackexchange.com/a/759086/433835 code \documentclass{article} \usepackage{graphicx} \usepackage{chemstyle} % Provides the 'scheme' float environment (and general chem document styling) \usepackage{chemnum} % Provides compound numbering + psfrag-like replacement via \replacecmpd / \cmpd % --- Two "parallel" compound series trick ------------------------------------ % chemnum internally uses ONE main counter: cmpdmain. % To emulate two independent series (literature vs EG), we: % 1) save the current main counter value % 2) swap in the saved EG counter state % 3) turn on the "EG" prefix % 4) after the EG block, save the updated EG state and restore the main counter \newcounter{cmpdMainSaved} % temp storage: saves the current literature/main cmpd counter \newcounter{cmpdEGstate} % persistent storage: remembers where the EG series left off \newcommand{\EGseriesBegin}{% % Save the current "main" (literature) compound counter: \setcounter{cmpdMainSaved}{\value{cmpdmain}}% % Switch cmpdmain to the last saved EG state (so EG numbering continues): \setcounter{cmpdmain}{\value{cmpdEGstate}}% % Turn on a bold "EG" prefix for printing compound labels (EG1, EG2, ...): \setchemnum{pre-label-code=\textbf{EG}}% } \newcommand{\EGseriesEnd}{% % Save the updated EG state (so the next EG block continues where we stopped): \setcounter{cmpdEGstate}{\value{cmpdmain}}% % Turn off the EG prefix (back to plain numbers): \setchemnum{pre-label-code=}% % Restore the literature/main counter exactly where it was before EG mode: \setcounter{cmpdmain}{\value{cmpdMainSaved}}% } \begin{document} % --- Literature compounds: should print as 1,2 -------------------------------- \begin{scheme}[H] \replacecmpd{lit:a.1} % Register/replace the placeholder in the graphic with compound "1a" \replacecmpd{lit:b} % Register/replace the placeholder in the graphic with compound "2" \includegraphics[width=.5\linewidth]{PhH-and-PhMe} \caption{Normal numbering} \end{scheme} % --- Your target compounds: should print as EG1, EG2 --------------------------- \EGseriesBegin % Switch into EG-series mode (prefix + separate counter state) \begin{scheme}[H] \replacecmpd{eg:a.1} % Register/replace placeholder with "EG1a" \replacecmpd{eg:b} % Register/replace placeholder with "EG2" \includegraphics[width=.5\linewidth]{PhH-and-PhMe} \caption{EG numbering} \end{scheme} \EGseriesEnd % Leave EG mode and restore literature numbering \cmpd{eg:a.1}, \cmpd{eg:b} \cmpd{lit:a.1}, \cmpd{lit:b} % --- Continue EG series: should now print as EG3, EG4 -------------------------- \EGseriesBegin \begin{scheme}[H] \replacecmpd{eg:d} % Expected: EG3 \replacecmpd{eg:e} % Expected: EG4 \includegraphics[width=.5\linewidth]{PhH-and-PhMe} \end{scheme} \EGseriesEnd \cmpd{eg:e} % --- Back to literature series: continues as 3,4 ------------------------------- \begin{scheme}[H] \replacecmpd{lit:c} % Expected: 3 \replacecmpd{lit:d} % Expected: 4 \includegraphics[width=.5\linewidth]{PhH-and-PhMe} \caption{Normal numbering} \end{scheme} \cmpd{lit:c} % --- Later EG block: continues again (no reset) -------------------------------- % NOTE: If you ever want to restart the EG series at EG1, you can reset the state: % \setcounter{cmpdEGstate}{0} \EGseriesBegin \begin{scheme}[H] \replacecmpd{eg:f} \replacecmpd{eg:g} \includegraphics[width=.5\linewidth]{PhH-and-PhMe} \end{scheme} \EGseriesEnd \end{document}

I am working on a typographical project that consists in an English translation from a foreign language text with a commentary. I would like to organise the material as follows: on the left page (i.e., on even-numbered pages) the original text on the right page (i.e., on odd-numbered pages) the English translation The two texts should run independently of each other. In other words, the original text should scroll along the left pages and the English text along the right. Moreover I would like to have the commentary at the bottom of each page and this should also run independently of the rest, following, contrarily to the two previous points, the flow of each page, without distinction of even or oddness. I would like also an horizontal line separating the commentary from the rest, although at the moment I do not care whether the line on the left page is aligned with the one on the right. What packages should I use? Are there any templates already available with similar characteristics? Suggestions from the experts? Thank you in advance for your help. Later edit: with the help of the packages reledpar and reledmac I managed to address 1. and 2. Here is a minimal example with a solution I am satisfied with. \documentclass[12pt,twoside]{book} \usepackage[english]{babel} \usepackage[T1{fontenc} \usepackage[series{},nocritical,noend,noeledsec,nofamiliar,noledgroup]{reledmac} \usepackage{reledpar} \usepackage{blindtext} \usepackage{geometry} \title{Test} \author{Cardinal Puff} \date{\today} \begin{document} \frontmatter \maketitle \mainmatter \begin{pages} \begin{Leftside} \selectlanguage{latin} \beginnumbering \pstart \blindtext[12] \pend \endnumbering \end{Leftside} \begin{Rightside} \beginnumbering \pstart \blindtext[12] \pend \endnumbering \end{Rightside} \end{pages} \Pages \end{document} However, in those packages I did not find an option to have a running bottom text independent of the upper part. In conclusion, 3. has still to be solved.

I am writing a large LaTeX book in VS Code using the LaTeX Workshop extension and LuaLaTeX. My file structure looks like this: Desktop/ └── epsilon/ ├── main.tex ├── chapter1.tex ├── chapter2.tex └── ... In main.tex I have: \documentclass[12pt,a4paper]{book} \usepackage[utf8]{inputenc} \begin{document} \tableofcontents \include{chapter1} \include{chapter2} \end{document} I configured LaTeX Workshop with a recipe to compile LuaLaTeX twice to generate the table of contents, and I disabled auto-clean: "latex-workshop.latex.recipe.default": "lualatex twice" "latex-workshop.latex.autoBuild.run": "onSave" "latex-workshop.latex.autoClean.run": "never" "latex-workshop.view.pdf.viewer": "tab" The problem: On the first compile, the table of contents appears correctly. However, on subsequent saves/compiles, the table of contents disappears from the PDF, even though the .toc file still exists in the folder. Things I tried: Changing PDF viewer from "tab" to "external". Using manual terminal compile (lualatex main.tex twice). Using latexmk -lualatex -pdf main.tex. Disabling autoBuild completely. None of these fully fixed the problem in VS Code. Interestingly, when I upload the same project to Overleaf, the table of contents always works, but for large books it sometimes times out during compilation. My questions: Why does the table of contents disappear in VS Code with LaTeX Workshop even when .toc exists? Is there a reliable workflow in VS Code / LaTeX Workshop for large books to generate the table of contents automatically without it disappearing? Are there known limitations with LaTeX Workshop and \tableofcontents for large projects? Thank you for any guidance!

I want to use the entire \textwidth at a table, so I chose tabularx. The table contains plots (all the same size) and boxes with titles that contain varying amounts of text or lines. The "title boxes" should all be top-aligned, all have the same width and for each row (!) the same height. This means that the "title boxes" in row 1 have the same height, and those in row 3 also have the same height; but possibly a different height than in row 1. What's the best way to configure this? I've put the "title boxes" also into tabularx tables; but perhaps multirow would be more suitable here (?). I often have problems with overfull / underfull hbox warnings here. I don't know what the ideal solution for this. Note: I plan to disable the main table's rules later; I've set \setlength\arrayrulewidth{2pt} here to better visualize the dimensions. \documentclass[paper=a5]{scrarticle} \usepackage[margin=14mm, showframe]{geometry} \usepackage{tabularx} % \usepackage{multirow}% needed? \usepackage{pgfplots} \pgfplotsset{compat=1.18} \usepackage{lipsum}% dummy text \newcommand\mytitle[1]{% {\begin{tabularx}{\linewidth}{|X|} \hline #1 \\ \hline \end{tabularx}} } \newcommand\myplot[1]{% \begin{tikzpicture}[baseline] \begin{axis}[width=\linewidth, height=30mm] \addplot[#1, mark=*]{x^4}; \end{axis} \end{tikzpicture}} \newcolumntype{Y}{% hspaces should be as small as possible @{\hspace{1.5pt}}X@{\hspace{1.5pt}}} \setlength\arrayrulewidth{2pt}% to see the effects \begin{document} \noindent\begin{tabularx}{\textwidth}{| Y | Y |} % Title 1 (row 1, column 1) ================== \mytitle{Title 1: \lipsum[1][1-2]} % Title 2 (row 1, column 2) ================== & \mytitle{Title 2: \lipsum[1][1]} \\ % Plot 1 (row 2, column 1) ================== \myplot{brown} % Plot 2 (row 2, column 2) ================== & \myplot{red} \\ \hline % Title 3 (row 3, column 1) ================== \mytitle{Title 3: \lipsum[1][2]} % Title 4 (row 3, column 2) ================== & \mytitle{Title 4: \lipsum[1][1-4]} \\ % Plot 3 (row 4, column 1) ================== \myplot{blue} % Plot 4 (row 4, column 2) ================== & \myplot{orange} \\ \end{tabularx} \end{document}

For many years, I had no problem with using the latexmk directives like: % !TEX TS-program = lualatexmk in TeXShop. Recently, however, that doesn't work anymore - after some update, unfortunately I don't remember exactly when it no longer worked. But now, when I compile something like: % !TEX TS-program = lualatexmk \documentclass[10pt]{article} \begin{document} test \end{document} it always gives me This is pdfTeX, Version 3.141592653-2.6-1.40.28 (TeX Live 2025) (preloaded format=pdflatex) restricted \write18 enabled. (or whatever else is selected in TeXShop) My TeX Live is all up to date, and I've deleted TeXShop.plist and all the TeXShop folders to reset but to no avail. Does anyone have any clue about where I should be looking for the problem?

I am using fontspec in order to write in Times New Roman. The authors of cited literature are always set in small caps. This initially made problems because the font has no small caps, but I solved those by googling and finding a solution on stackexchange. However, the small caps don't work when they are also bold, e.g. in a section heading. This is my MWE: \documentclass[12pt]{article} \usepackage[utf8]{inputenc} \usepackage[ngerman]{babel} \usepackage{fontspec} \setmainfont{Times New Roman}[ SmallCapsFont={TeX Gyre Termes}, SmallCapsFeatures={Letters=SmallCaps}, ] \begin{document} \section{Regel von \textsc{Ritschl}} Regel von \textsc{Ritschl} \end{document} Which produces: As you can see, the small caps in the text body work just fine. In the heading, however, the small caps are not set bold. When using the ebgaramond package, this issue does not occur and everything looks as it should and very pretty, but, of course, in Garamond: I actually prefer the looks of Garamond but unfortunately I have to write in Times New Roman. Does anyone know how this could be fixed? Thanks in advance! If relevant: I am using LaTeX with LaTeX workshop in VSCode on a MacBook Air.

I would like to crop x percent from each side from the img. \documentclass{article} \usepackage{graphicx} \begin{document} \begin{figure}[h] \centering \includegraphics[scale=0.3]{example-image-a} \caption{Caption} \label{fig:placeholder} \end{figure} \end{document} insted of using \includegraphics[scale=0.3]{example-image} I would like to call \cropimg{scale}{img}{crop percentage}

My new keyboard writes ^ as ˆ, and overleaf doesn't recognize these the same way. Is there an alternative symbol in latex for writting powers and indexes or some way to make overleaf recognize ˆ as ^?
