Hot

This question is similar to this question, but not exactly the same. I have the following code: \documentclass[tikz,border=5pt]{standalone} \begin{document} \begin{tikzpicture} \draw[help lines] (-1,-1) grid (7,2); \draw[thick,magenta] (0,0) .. controls (3,3) and (4,-1) .. % coordinate[pos=.3] (A) %<- point start of thick line % coordinate[pos=.5] (B) %<- point end of thick line (6,0); \clip (2,0) rectangle (3,3); \draw[line width=3pt,cyan] (0,0) .. controls (3,3) and (4,-1) .. (6,0); \end{tikzpicture} \end{document} Noted that the GREEN cut is what I was after, the cut should along the path, but not the \clip-ed rectangle. What I saied is not the same as Paul Gaborit's solution, is that I want to control the proportion of (says 0.3 and 0.5, and coloe them thicker) the "subpath". The solution with: decoration={ show path construction, curveto code={ \addtocounter{pos}{1} \pgfmathtruncatemacro{\min}{#1 - 1} \ifthenelse{\thepos < #2 \AND \thepos > \min}{ \draw[#3] (\tikzinputsegmentfirst) .. controls (\tikzinputsegmentsupporta) and (\tikzinputsegmentsupportb) .. (\tikzinputsegmentlast); }{} } } points here \tikzinputsegmentfirst, \tikzinputsegmentsupportX and \tikzinputsegmentlast looks not easy to control two points position as pos=0.3, is there any better solution? Any possible(plain-TikZ,tkz-elements,luadraw) are all welcome!

I want the following result: There are two features I want to control: The columns: First Col to be itshape Second Col to add cmdA left Third Col to add cmdB right The rows: What's more, every line's content is the same, replicated for THREE times. It could be achieved by: \documentclass[border=1cm]{standalone} \usepackage{tabularray} \DeclareRobustCommand{\cmdA}[1]{cmdA#1}% \DeclareRobustCommand{\cmdB}[1]{#1cmdB}% \newcommand\columnA[1]{\textit{#1}} \newcommand\columnB[1]{\cmdA{#1}} \newcommand\columnC[1]{\cmdB{#1}} \NewExpandableDocumentCommand{ \addcols }{ m }{ {#1} & {#1} & {#1} \\} \begin{document} \begin{tblr}[expand=\addcols]{ colspec = {*{3}{X[c,m,5cm]}}, row{1} = {font=\Large\bfseries}, cell{2-Z}{1} = {cmd=\columnA}, cell{2-Z}{2} = {cmd=\columnB}, cell{2-Z}{3} = {cmd=\columnC}, hlines={1.5pt}, vlines={1.5pt}, } ColA & ColB & ColC \\ % \addcols{Line1} % \addcols{Line2} % \addcols{Line3} Line1 & Line1 & Line1 \\ Line2 & Line2 & Line2 \\ Line3 & Line3 & Line3 \end{tblr} \end{document} Now, assuming that there are too many columns(for example,10 columns), it's diffcult to type it for so many times. So I tried with \addcols, but the expand and cell{...}={cmd=...} complained with: ! Misplaced alignment tab character &. \addcols code #1-> {#1} & {#1} & {#1} \\ l.26 \end {tblr} ? Is that possible to achieve this at the same time?

I am currently trying to rewrite the code of @Tobi (https://tex.stackexchange.com/a/57317/98739) for a thumb index using LaTeX3-syntax.

I am writing my thesis using the yathesis.cls class, and I want to remove the default title and cover pages generated by yathesis.cls in order to use a title page mandated by my university for my manuscript. I first tried commenting out the \maketitle command in the main these.tex file, but the compiled PDF was no longer archivable in PAC. Then, I tried removing the title and cover pages directly from the generated PDF, but the file still wasn’t archivable. Is it possible to perform this modification without corrupting the generated PDF and while maintaining PDF/A compliance?

When I saw this thread How to customize CircuiTikz ac - dc symbols or this one Showcase of beautiful typography done in TeX & friends, I had the idea to add a showcase for electrical circuit diagrams. The package would typically be circuitikz. Feel free to post your large, small, or elegant circuit diagrams here in the community wiki. (I will also add some examples occasionally.) Attach your codes (if possible); this would be a great opportunity to learn from your coding and your style. \documentclass[margin=5pt, multi=circuitikz]{standalone} \usepackage{circuitikz} \begin{document} \begin{circuitikz}[european resistors] \draw[] (0,0) to[R=$R_1$, a_=$1\Omega$, name=R1, invert] (3,0); \end{circuitikz} \end{document}

(Overleaf) I am trying to make a page border for cover page only (the first page) as shown in the figure. Any idea to achieve this?

In the example below, how can the linear-gradient overlay be confined to within the black frame without having to tinker around with the dimensions in \defineoverlay? I suppose that the outer frame and the overlay are siblings in the page box rather than the overlay being a child of the frame, although the overlay is the background of the frame which might be expected to be bound by the frame's size. Is there an equivalent concept as CSS clip or overflow hidden, such that if the text in the frame changes the size of the frame, the overlay will be adjusted automatically? Thank you. \starttext \defineoverlay [OL2] [ \startMPcode % fill fullsquare xyscaled (TextWidth,TextHeight) fill fullsquare xyscaled (35mm,25mm) withshademethod "linear" withshadedirection (3.5,.5) withshadecolors("darkgreen","darkblue"); \stopMPcode ] \framedtext[ width=fit, align=middle, background=OL2, rulethickness=3pt, offset=2mm, ] { \framedtext[ width=fit, align=middle, background=color, backgroundcolor=yellow, frame=off, ] { Some lines of text. }} \stoptext Added If the line is changed to fill fullsquare xyscaled (OverlayWidth,OverlayHeight) the result is that the width of the overlay still excedes the frame on the right. I'm still doing something wrong. Thanks. I was very sloppy in declaring the commands for the overlay, and forget that I'm not writing code but markup with code in it; and those returns after the [ and the line before the ] can't be left like that. Sorry. After fixing that, it works fine.

But I have done so globally. How could I achieve changing it within the verse, such that for example the first apparatus entry begins with 1Sb and the second one with 1Pd? The use case is for bilingual poetry, where the same text can be read in two languages, with different segmentation and meaning. 1S stands for Sanskrit, i.e. verse 1 read as Sanskrit, and 1P for Prakrit.

I wanted to understand how to assign names to fonts GraphicSeriesFontSet from CASIO website https://edu.casio.com/education/fontset/dl/GraphicSeriesFontSet.zip in order to use them without installing them, by copying them directly into a folder on the desktop. My .tex document must be located inside the same folder. The goal is to include the fonts in the document without installing them on the system, for my work. In the folder, I have the following fonts available: CFX06.ttf, CFX01.ttf, CFX02.ttf, CFX04.ttf, CFX05.ttf. I am not sure how to use them correctly in both mathematical mode and regular text mode. Note that I have not able to see the font of the package casiofont (https://github.com/amunn/casiofont?tab=readme-ov-file). In fact I noticed this mistake: \documentclass[12pt]{standalone} \usepackage{casiofont} \begin{document} \Abs \end{document} This is LuaHBTeX, Version 1.24.0 (MiKTeX 25.12) restricted system commands enabled. luaotfload | db : Reload initiated (formats: otf,ttf,ttc); reason: Font "CASIOClassWiz" not found. ! Package fontspec Error: (fontspec) The font "CASIOClassWiz" cannot be found; this may (fontspec) be but usually is not a fontspec bug. Either there (fontspec) is a typo in the font name/file, the font is not (fontspec) installed (correctly), or there is a bug in the (fontspec) underlying font loading engine (XeTeX/luaotfload).

My accessibility checker (Ally) complains that the following "PDF does not have headings": \DocumentMetadata{tagging=on,lang=en-US,pdfstandard=ua-2, tagging-setup={ math/setup=mathml-SE, % role/new-tag=Title/H1, } } \documentclass{article} \usepackage{lipsum} \title{Title} \begin{document} \maketitle \lipsum[1-9] \end{document} I saw elsewhere that uncommenting the role line would cause the title to become an H1, satisfying the need for headings. This satisfies Ally, but now the compilation gives a warning Parent-Child 'pdf2:H1' --> 'pdf2:P'. Relation is not allowed! and VeraPDF says that the PDF is no longer UA-2. Is there a way to make the title become H1 and not P?

I have the following LaTeX code using the chemstyle and chemnum packages: \documentclass{article} \usepackage{graphicx} \usepackage{chemstyle} \usepackage{chemnum} \begin{document} \begin{scheme} \replacecmpd{PhH} \replacecmpd{PhMe} \includegraphics[scale=0.8]{chem.eps} \caption{Caption I} \label{sch:first} \end{scheme} % In my real project the chemicals are different \begin{scheme} \replacecmpd{PhNH2} \replacecmpd{PhNO2} \includegraphics[scale=0.8]{chem.eps} \caption{Caption II} \label{sch:second} \end{scheme} \end{document} I would like to define a new command, for example \schCall, that wraps this structure into a single macro. Desired syntax example: \schCall[0.6]{chem}{PhH, PhMe}{Caption I}{first} Where: the optional argument is the scale (default = 0.8) the first mandatory argument is the image filename (without .eps) the second mandatory argument is a comma-separated list of arguments for \replacecmpd the third argument is the caption text the fourth argument is used for the label

I'm writing up a financing proposal for which I'd like to list the expenses by category, providing each invoice block with its own subtotal, and then a separate line at the end giving a combined total for all. I'm using the invoice2 package. For example, I have the following: \begin{invoice}[currency-symbol={€{}}, currency-in-header=true, included-vat=true] % count contents rate/unit \invoiceitem{1}{Zoom H6Studio Aufnahmegerät}{433} \invoiceitem{1}{Zoom EXH-6e Adapter}{105} \invoiceitem{1}{Zoom APH-6st case}{64} \invoiceitem{6}{Roadworx Mic Stand plus 10m Kabel}{22} \invoiceitem{6}{Shure SM 7 B EVA Microphone Case Bundle}{413} \invoiceitem{1}{R{\o{}}de Stereo Bar SB20}{36} \invoiceitem{1}{Zoom Q8n-4k Video Camera}{389} \invoiceitem{2}{Manfrotto MVKBFRT-LIVE Befree Alu Tripod}{185} \end{invoice} (this is the a/v equipment). The total returned is €4.007,00. I would like to pull this total, and combine it with the totals from other invoice blocks, to give a grand total combining all categories. Is there any way to do that? Is the output of a given invoice block stored as a variable anywhere that can be called up by a later function? Is there any way to refer to it? Cheers

I need to group or segment the entries in a reading list (so there are no separate citations: I just use \nocite{*}). The examples in the biblatex docs all seem to require individual citation in a refsegment or refsection, and create a subheading in the references output. Is there a field I can add to each entry that can be passed by (eg) \nocite{value} to biber so it can use it to group the output?

Asymptote appears to be correctly installed in my MiKTeX distribution; however, the document does not compile and produces the following error: Package asymptote Warning: file `spy-1.pdf' not found on input line 15. (spy.aux)) No pages of output. Transcript written on spy.log. Sorry, but "MiKTeX Compiler Driver" did not succeed. I do not use Asymptote very often, so I am not sure about the cause of the problem. It is possible that the solution is related to what is discussed in the following TeX.StackExchange threads: 'filename-1.pdf' not found Asymptote Asymptote Code Generates .asy Files, But Asymptote Execution Fails In particular, I have not yet tried the solution proposed by the user user279206, and I do not know whether there is an alternative approach that would allow me to compile the document correctly with my MiKTeX distribution. In a previous question, I also asked whether it is possible to obtain the same arrow tip styles provided by Asymptote using TikZ: Arrows with spherical (conical) tips Since I do not understand Asymptote code, I kindly ask whether it would be possible to modify the original code by removing everything that is not strictly necessary, in order to obtain only the figure related to spherical coordinates, without the volume element and without additional unnecessary details to obtain this with the portion of a sphere. In TikZ there is a result: https://tikz.net/spherical_1/ This is my goal:

I'm writing a report using KOMA-Script (scrreprt) and want to include a "Nomenclature" chapter. This chapter is unnumbered (\chapter*{Nomenclature}) and should appear in the table of contents.

I’m using Overleaf and have added comments to my document using Overleaf’s comment feature. Is there a way to make these comments appear in the compiled PDF, or to embed them directly into the LaTeX file itself? I’d like the comments to be visible to others who only have access to the PDF or the .tex source. I found an answer to this, but it’s from several years ago and might be outdated: Printing PDF from overleaf with comments included

Obviously, I don't know what I'm doing, here, but just experimenting with Ch. 4 of metafun xl. The first frame in the example below has one string of text, such that the shading applies to the whole string. In attempt at varying the shading direction/colors by letter, I tried building each letter separately in the second frame and find that: the first letter "J" no longer drops below the line the middle "m" appears slighlty higher than the rest of the letters and to get spacing between the letters, I hackishly added an \hskip{-0.65mm}. Question is, Is there a better way to vary shading by letter; and, if not, how can I fix these items such that the by-letter version looks as close to the single-string version but with varied shading. Also, please, is it possible to both draw and shade the fill? It appears that if kind=outline cannot draw and if kind=draw cannot shade because an error is thrown of unknown path mfun_shade_path.

To do this, I am trying to label the areas using barycentric coordinates, because I want the label to appear in the centre of the triangle.

For slant = 0, k should work out to sqrt(1.75) = 1.32287565553..., and A = 45°, however due to a bug, the k is a few eyelets shy of the expected sqrt(1.75), and the line becomes too thin. As for the A, it maybe is correct but I don't know if it is. There are bugs and I don't know how to fix them.

I like my matrix indices to be center-aligned while numbers within the matrix should be right-aligned for better visual clarity of scale. However, none of my attempts to achieve both have been successful. In the example below, the first option is closest, but fails to align the lost column index. \documentclass{article} \usepackage{nicematrix,xcolor} \newcommand{\mc}{\multicolumn{1}{c}} \begin{document} Manual formatting without \texttt{first-row} - last column index not centered: \[ \begin{NiceArray}{ *{6}{r} } \mc{\color{red}\scriptstyle 0} & \mc{\color{red}\scriptstyle 1} & \mc{\color{red}\scriptstyle 2} & \mc{\color{red}\scriptstyle 3} & \mc{\color{red}\scriptstyle 4} & \mc{\color{red}\scriptstyle 5} \\ 8 & 5 & 16 & 19 & 10 & 5 \\ 12 & 5 & 12 & 15 & 9 & 14 \\ 19 & 13 & 6 & 2 & 12 & 3 \\ 7 & 18 & 13 & 0 & 0 & 17 \\ 6 & 10 & 2 & 7 & 11 & 16 \CodeAfter \SubMatrix[{2-1}{6-6}] \end{NiceArray} \] Using \texttt{\string\RowStyle} - no centering of indices: \[ \begin{NiceArray}{ *{6}{r} } \RowStyle[nb-rows=1]{\color{red}\scriptstyle} 0 & 1 & 2 & 3 & 4 & 5 \\ 8 & 5 & 16 & 19 & 10 & 5 \\ 12 & 5 & 12 & 15 & 9 & 14 \\ 19 & 13 & 6 & 2 & 12 & 3 \\ 7 & 18 & 13 & 0 & 0 & 17 \\ 6 & 10 & 2 & 7 & 11 & 16 \CodeAfter \SubMatrix[{2-1}{6-6}] \end{NiceArray} \] Using \texttt{first-row} - no centering of indices: \[ \begin{NiceArray}{ *{6}{ r } }[first-row,code-for-first-row=\color{red}\scriptstyle] 0 & 1 & 2 & 3 & 4 & 5 \\ 8 & 5 & 16 & 19 & 10 & 5 \\ 12 & 5 & 12 & 15 & 9 & 14 \\ 19 & 13 & 6 & 2 & 12 & 3 \\ 7 & 18 & 13 & 0 & 0 & 17 \\ 6 & 10 & 2 & 7 & 11 & 16 \CodeAfter \SubMatrix[{1-1}{5-6}] \end{NiceArray} \] Using \texttt{first-row} with \texttt{c}entered columns - no right-aligned matrix elements: \[ \begin{NiceArray}{ *{6}{ c } }[first-row,code-for-first-row=\color{red}\scriptstyle] 0 & 1 & 2 & 3 & 4 & 5 \\ 8 & 5 & 16 & 19 & 10 & 5 \\ 12 & 5 & 12 & 15 & 9 & 14 \\ 19 & 13 & 6 & 2 & 12 & 3 \\ 7 & 18 & 13 & 0 & 0 & 17 \\ 6 & 10 & 2 & 7 & 11 & 16 \CodeAfter \SubMatrix[{1-1}{5-6}] \end{NiceArray} \] \end{document} How can I achieve a different alignment for the first row (indices) compared to the rest of the matrix?

I'm working on large LaTeX projects with structured directories containing numbered files: project/ ├── 01-introduction.tex ├── 02-background.tex ├── 03-methodology/ │ ├── 01-experimental.tex │ ├── 02-analysis.tex │ └── 03-validation.tex ├── 04-results/ │ ├── 01-figures.tex │ └── 02-tables.tex └── 05-conclusion.tex Currently, I manually write \import{} commands: \import{project/01-introduction} \import{project/02-background} \import{project/03-methodology/01-experimental} \import{project/03-methodology/02-analysis} \import{project/03-methodology/03-validation} \import{project/04-results/01-figures} \import{project/04-results/02-tables} \import{project/05-conclusion} This approach is: Verbose - requires li sting every file Error-prone - easy to miss files or get order wrong Hard to maintain - adding new files requires manual updates Question: What's the most robust way to automate .tex file imports while ensuring correct hierarchical and numerical ordering? Ideally, I'd like a solution that works with a simple command like: \importAll{path=./project/, recursive=true}

In the MWE \documentclass{article} \usepackage{lua-visual-debug} \setlength{\parindent}{0pt} \setlength{\parskip}{0pt} \begin{document} \rule{6mm}{6mm} \rule{7mm}{6mm} \end{document} the code contains an empty line (= new paragraph) between the two \rules. This is what it looks like in the output: Between the paragraphs, some vertical spacing is inserted. As far as I can tell, it is exactly 1pt. Where does this come from, and how am I supposed to modify it? This space does not occur when using minimal document class; it apparently is limited to article (or other high-level classes like KOMA).

I'm trying to typeset the following table. I'm having trouble with the vertical centering of each cell's contents, plus the obvious horizontal alignments. ChatGPT's numerous attempts were all hopelessly wrong, and I eventually created the image below in Powerpoint, which (sadly) might have to be my solution, if all else fails.
