MWE: \documentclass[tikz,border=1pt]{standalone} \usepackage{tikz} \usepackage{calligra} \usepackage[T1]{fontenc} \begin{document} \begin{tikzpicture}[line width=1pt] % \path[use as bounding box] (1,0) rectangle (12,7); % Outer rectangle \draw (0,0) rectangle (12,7); % Curvy E outside the box \node[anchor=center, font=\calligra\fontsize{38}{38}\selectfont] at (-1.5,6.75) {E}; % Left circle \draw (4.0,3.4) circle (2.75); % Right circle \draw (8.25,3.45) circle (2.2); % Labels \node[font=\fontsize{28}{28}\selectfont] at (1.8,5.8) {$P$}; \node[font=\fontsize{28}{28}\selectfont] at (9.4,5.9) {$Q$}; \end{tikzpicture} \end{document} This gives me this picture: There, you see a white space on the left that needs to be trimmed. My best knowledge is using: \path[use as bounding box] (1,0) rectangle (12,7); but it gives me: I want to control it like 1pt or 2pt or 1cm, 2cm to mean that I trim that much. How to do that? I tried to control (1,0), but it doesn't work as I expected. Also, if possible, I don't want to crop it outside, like using \includegraphs and trim it. It is saving time to trim it inside the TikZ, IMHO.

As a teacher, you might find this question relatable should you be bothered by making sure that the sum of marks is a certain number when you make an exam. Since I believe LaTeX has control flow, I think it would be great to have a feature to count how many marks I have made so far. So, in this particular document, if it is possible, could I have a mini program that would print a number of sum of the marks? If I exceed the number of max marks, it will give a warning that been printed out below the instruction. just like if else condition. To ilustrate it, Suppose my first problem gives [3] marks, second problem has [4] marks, third problem has [1] mark and the last problem has [6] marks. I want a command to print the sum of them in a sentence like this: The total mark for this paper is \mark. Is this doable? How to? I'll just provide this MWE and let you geniuses take care of it please.

It is still a manual writing "19". so there, perhaps how to create command such as \mark. so it would print 19 by itself, because the LaTeX does the maths automatically. And if it exceeds 19, then print WARNING: TOTAL MARKS EXCEED 19.

In the image below, the vertical spacing between all list items within the same level and between changes in levels looks correct, except that between (2.) and a. How can I correct it, such that the start of the italic a,b,c level has the same vertical spacing as the rest? In the image, that is the space between (2.) Paren 2 and a. Italic a. It's confusing because the spacing between the b. Italic b and 1. Italic 1 is correct. I tried using the before=\blank[1ex] and it appears to make no change. Thank you. \defineitemgroup[ItemsParen] \setupitemgroup [ItemsParen] [each] [unpacked] [ left=(, right=), stopper=., distance=1em, indenting=no, align=yes, inbetween={\blank[halfline]}, ] \defineitemgroup[ItemsItalic] \setupitemgroup [ItemsItalic] [each] [unpacked] [ stopper=., distance=0em, indenting=no, align=yes, inbetween={\blank[halfline]}, style=\italic, ] \startTEXpage \startItemsParen[n] \startitem Paren 1 \stopitem \startitem Paren 2 \startItemsItalic[a] \startitem Italic a \stopitem \startitem Italic b \startItemsItalic[n] \startitem Italic 1 \stopitem \startitem Italic 2 \stopitem \stopItemsItalic % [n] \stopitem % Italic b \startitem Italic c \stopitem \stopItemsItalic % [a] \stopitem % Paran 2 \startitem Paren 3 \stopitem \stopItemsParen \stopTEXpage For a comparison without defining an item group(s), it can be seen that the spacing is the same throughout the lists. \startTEXpage \setupitemize[1][unpacked][left=(,right=),stopper=.,distance=1em] \setupitemize[2][unpacked][stopper=.,style={\it},] \setupitemize[3][unpacked][stopper=.,style={\it},] \startitemize[n] \startitem Paren 1 \stopitem \startitem Paren 2 %\stopitem \startitemize[a] \startitem Italic a \stopitem \startitem Italic b %\stopitem \startitemize[n] \startitem Italic a.1 \stopitem \startitem Italic b.2 \stopitem \stopitemize \stopitem % Italic b \startitem Item c \stopitem \stopitemize \stopitem % Paren 2 \startitem Paren 3 \stopitem \stopitemize \stopTEXpage After adding the above, I think it points to my error, which is thinking that a new define group name is needed for each level of a list. It appears that one definition subsequently setup for each level defines the entire list at all levels; and a new definition group name is a completely new list with all its levels. Thus, if the first example is changed to: \defineitemgroup[Items] \setupitemgroup [Items] [1] [unpacked] [ left=(, right=), stopper=., distance=1em, indenting=no, align=yes, inbetween={\blank[halfline]}, ] \setupitemgroup [Items] [2,3] [unpacked] [ stopper=., distance=0em, indenting=no, align=yes, inbetween={\blank[halfline]}, style=\italic, ] then the spacing is as expected. Thus, this might just be another stupid question of mine that should just be deleted. Thank you.

I am close to having the table that I want. There are five desired modifications. I would like to have "Species" and "host" at the bottom of the row containing the column headings. Here are the remaining modifications. I would like a double bar, "||", in bold along the left and right edges of the table. I only have it along the last three rows of the left edge - and not in bold. The vertical line separating the first and second columns is not drawn in bold. The vertical line separating the second and third columns and the vertical line separating the third and fourth columns is only drawn through the first row. Lastly, the numbers in the third and fourth columns should be centered. \documentclass[10pt]{amsart} \usepackage[utf8]{inputenc} \usepackage{soul} \usepackage{ragged2e} \usepackage{mathtools,array} \usepackage{adjustbox} \usepackage{makecell} \begin{document} \begin{tabular}{|| c | c p{2cm} p{3cm}| c p{3cm} ||} \hline \multicolumn{1}{| p{2cm} |}{\centering \textbf{Plant} \\ \textbf{Species}} &\multicolumn{1}{| p{2.5cm} |}{\centering \textbf{Mycorrhizal} \\ \textbf{host}} & \multicolumn{1}{| p {4.5cm} |}{\centering \textbf{Average Mass (in grams)} \\ \textbf{of plants grown in soil} \\ \textbf{containing} \\ \textbf{Mycorrhizal fungi}} & \multicolumn{1}{| p {4.5cm} |}{\centering \textbf{Average Mass (in grams)} \\ \textbf{of plants grown in soil} \\ \textbf{treated to kill} \\ \textbf{Mycorrhizal fungi}} \\ % Use multicolumn and centering for the header \hline Corn&Yes&15.1&3.8 \\ \hline Marigold&Yes&10.2&2.4 \\ \hline Broccoli&No&7.5&7 \\ \hline \end{tabular} \end{document}

I have not been able to use arc(triple c, real r, real theta1, real phi1, real theta2, real phi2,triple normal=O); instead I use the version arc(triple c, triple v1, triple v2, triple normal=O,bool direction=CCW) which means I have to keep using transforms to get each arc to compute. Instead of attaching a Label to the draw function of each arc I use label to do this separately by guessing the correct coordinate for the label. There should be an easier way to do this for someone who knows how to properly use the arc function. I would be grateful if someone could show me a more efficient way of generating this graph.

I am carrying out some work that insists on using $$ ... $$ instead of \[ ... \] for maths (not my choice, I am forced into using it). Trouble is I also need to add a tag to an equation. Normally I would do this as \[ a = b \tag{1} \] But this does not work if I change it to $$ a = b \tag{1} $$ Want to ask how I can add tags with dollar signs? Every post I have looked at so far suggests using \[ ... \], which is just not allowed in this case (I do agree in general that \[ ... \] should be used though).

I need help writing the previous linear program on Overleaf, I'm struggling to align the constraints and the objective function as well. Claude and ChatGPT are not good help.

I'm working on a document that contains quite a lot of tables. In many of these tables, some columns have normal text, while other columns have other things (e.g. inline images, math formulae, etc) that are taller than a normal line of text. With a normal tabular environment, the text ends up on the same baseline as the larger things, which doesn't look good. I would prefer it be vertically centered, so that the midline of the text lines up with the midline of the larger things. I've seen the tabularray package suggested, but it looks like that uses a very different syntax from a normal tabular, and I have many tables to update and a deadline in two days. I'm open to switching if there's a straightforward way to convert tabulars into tabularrays without changing anything about the default appearance or behavior, but otherwise, I'm worried about the dimensions changing. So: is there some way to change the behavior of a tabular (a certain table, a certain column, even a certain cell if necessary) so that text in cells is vertically centered, without changing anything else about its dimensions and layout? MWE: \documentclass[12pt,letterpaper]{book} \usepackage{booktabs} \begin{document} \begin{table}[h] \centering \begin{tabular}{ccc} \toprule Normal & Bigger & Normal \\ \midrule Lorem & {\Huge XYZ} & Ipsum \\ \midrule Dolor & {\Huge ABC} & Sit \\ \midrule Consec & {\Huge JKL} & Tetur \\ \bottomrule \end{tabular} \end{table} \end{document} I would like the midline of the smaller text to line up with the midline of the huge text, while keeping everything else about the table the same. I've seen many questions about vertically centering text in table columns, but none of the answers I've seen allow keeping the rest of the table the same (they tend to involve switching to a different environment with different behavior). I've seen that a single-cell multicolumn will center things vertically, but adding those to every single cell in many separate tables is going to be a nightmare, so I'd prefer something I can use once per table instead of once per cell if possible.

Here below is the example code: \documentclass{article} \usepackage{unicode-math} \setmathfont{TeX Gyre Pagella Math} \begin{document} Inline $(\frac{1}{b} , \frac{1}{a})$ \[ (\frac{1}{b} , \frac{1}{a})\] \end{document} Noted that the baseline of a is abnormal when inline, but normal in display. Is that a bug or feature of TeX Gyre Pagella Math? That is also quite confusing for me that why inline and display behave quite different, is not the same a glyph was used? Any hot-fix to change the baseline in inline math for a here? Any tricks(maybe luatex?) are all welcome!

I was following a thread on how to add images to header/footer of a document class article. I found a pretty neat solution for the header which spans the entire paperwidth as I need to do. However, I upon trying and replicate the same for the footer I don't quite get the same result...; I attempted to change what I believe was relevant but I must have missed something. Below the code used MWE \documentclass[11pt]{article} \usepackage[inkscapearea=page]{svg} \usepackage{graphicx} \usepackage[letterpaper,margin=1in,headheight=14pt,footskip=59pt]{geometry} \usepackage[inline]{enumitem} \usepackage[utf8]{inputenc} \usepackage[T1]{fontenc} \usepackage{titlesec} \usepackage{lastpage} \usepackage{fancyhdr} \pagestyle{fancy} \usepackage{titling} \usepackage{xcolor,hyperref} \usepackage{tikz} \usetikzlibrary{calc} \usepackage{tikzpagenodes} \titleformat{\section}[hang]{\large\bfseries\color{coolblack}}{\thesection\;|}{1em}{} \titleformat{\subsection}[hang]{\normalsize\bfseries}{\hspace{.15in}\thesubsection\;|}{1em}{} \hypersetup{ colorlinks, citecolor=electricultramarine, filecolor=., linkcolor=white, urlcolor=mediumtealblue, linktoc=all } \definecolor{coolblack}{rgb}{0.0, 0.18, 0.39} \definecolor{mediumtealblue}{rgb}{0.0, 0.33, 0.71} \definecolor{electricultramarine}{rgb}{0.25, 0.0, 1.0} \setenumerate[1]{label={\emph{\roman*)}}} \fancyhf{} \renewcommand{\headrulewidth}{0pt} \fancypagestyle{firststyle} { \lhead{\begin{tikzpicture}[remember picture,overlay] \draw let \p1=($(current page.north)-(current page header area.south)$), \n1={veclen(\x1,\y1)} in node [inner sep=0.5,outer sep=0.5,below right] at (current page.north west){\includegraphics[width=.996\paperwidth,height=.75in]{example-image-a}}; \end{tikzpicture}} \fancyfoot[R]{\textbf{\textcolor{white}{\footnotesize Page \thepage\ of \pageref{LastPage}}}} \lfoot{\begin{tikzpicture}[remember picture] \draw let \p1=($(current page.north)-(current page footer area.south)$), \n1={veclen(\x1,\y1)} in node [inner sep=0,outer sep=0,below right] at (current page.south west){\includegraphics[width=.996\paperwidth,height=.75in]{example-image-b}}; \end{tikzpicture}} } \author{Name Surname} \title{project: activity summary} \date{\today} \begin{document} \maketitle \thispagestyle{firststyle} \section{Test} \end{document} Also, I'm unsure whether it is related but I get prompted a: Label(s) may have changed. Rerun to get cross-references right. What I would require is for the footer image to align to the bottom-left corner as the header aligns to the top-left one. See picture

I encountered a strange behavior of biblatex/biber on an article. I have a document both containing German and English parts, hence I load babel with both ngerman and english as options. In my bibliography, I use the langid field to determine the language to be used for each entry. In most cases, this works fine, but the following MNWE yields a strange result: TeX-File: \documentclass{book} \usepackage[ngerman,english]{babel} \usepackage[T1]{fontenc} \usepackage[bibencoding=auto,backend=biber,autolang=other,giveninits=true,style=iso-authoryear,maxcitenames=3]{biblatex} \addbibresource{references.bib} \begin{document} \selectlanguage{ngerman} \fullcite{Held_2019} \end{document} Bib-File: @article{Held_2019, langid = {ngerman}, author = {Held, Andrea}, title = {Gut gelagert - Aktuelle Datenbanktechnologien}, subtitle = {ein Rundumschlag}, journal = {iX}, publisher = {heise}, number = {7/2019}, pages = {94}, year = {2019} } This yields (with pdflatex and biber): Note that it does print the number part (Nr.) correctly in German, but the page part (p.) in English. If I do not pass the english option to babel, everything works fine with this entry, but I cannot print English entries correctly. Somehow the English language is used only for the page part, but I have no clue why that happens or how I can fix it. Any ideas?

When trying to put a luadraw environment in a footer I obtain the following error Argument of \luacode@grab@lines has an extra  }. Is there any workaround? If needed, I can consider using \AddToHookNext{shipout/background} (but this is not working either). This is really related to luadraw, as replacing the luadraw code by the TikZ code compiles without problems. %!TEX TS-program = lualatex \documentclass{article} \usepackage{luadraw} \usepackage{fancyhdr} \pagestyle{fancy} % This does not work %\cfoot{% % \begin{luadraw}{} % local g = graph:new{window={0,1,0,1},margin={0,0,0,0}, bbox = false} % local L = { Z(0,0), Z(1,1) } % g:Dpolyline(L,true) % g:Show() % \end{luadraw} %} % But this works % This is the TikZ code produced by the above luadraw picture \cfoot{% \begin{tikzpicture}[line join=round]% \begin{scope}% \draw[] (0,0) -- (1,1)--cycle;% \end{scope}% \end{tikzpicture}% } \begin{document} bla blo bli \end{document} Edit. If possible I would like a solution where the luadraw environment is really executed at each page and can use \thepage as a parameter.

I am toying with luadraw and would like to have my graphic depending on \thepage for the number of iterations. I tried \\thepage, "\\thepage" or to use g:Writeln or tex.sprint but none of them worked. Minimal non-working example (inspired by the luadraw manual): %!TEX TS-program = lualatex \documentclass{article} \usepackage{luadraw} \begin{document} bla blo bli \begin{luadraw}{name=Sierpinski} local iteration = g:Writeln("\\thepage") %num? tex.sprint? local g = graph:new{window={-5,5,-5,5},margin={0,0,0,0},size={1,1}} local i = cpx.I local rand = math.random local A, B, C = 5*i, -5-5*i, 5-5*i -- triangle initial local T, niv = {{A,B,C}}, iteration for k = 1, niv do T = concat( hom(T,0.5,A), hom(T,0.5,B), hom(T,0.5,C) ) end for _,cp in ipairs(T) do g:Filloptions("full", rgb(rand(),rand(),rand())) g:Dpolyline(cp,true, "line width=0pt") end g:Show() \end{luadraw} \end{document}

I want to replicate the black label with the red label created with label node. \documentclass[tikz,border=1cm,12pt]{standalone} \usetikzlibrary{calc} \begin{document} \begin{tikzpicture} \draw (0,0) -- ++ ({sqrt(3)},{sqrt(11)}) node[pos=1/3,circle,fill,inner sep=1pt]{} % dot node[pos=1/3,label={[red,rotate={atan(sqrt(11/3))}]above:above}]{} % how can we make this label node[pos=1/3,above,sloped]{above}; % coincide with this label? \end{tikzpicture} \end{document} What am I missing here?

The text is indented but the number remains at the left. How can the list numbers be moved to the point of indentation, such that the itemize looks like the paragaphs that follow it in the example? When the numbers are arabic and under 10, a negative distance equal to the indentation appears to work, but when Roman numerals, such that the width varies, it no longer works. It is as if the distance is calculated from the left of the number rather than where it ends on the right. Thank you. \setupindenting[yes,3em,first] \setupitemize [1] [intext] %[intro] [ %distance=-3em, itemalign=, stopper=., right={---}, indenting={yes,3em}, ] \starttext \startitemize[R] \startitem \input{ward} \stopitem \startitem \input{ward} \stopitem \startitem \input{ward} \stopitem \startitem \input{ward} \stopitem \stopitemize I.\ --- \input{ward} \par II.\ --- \input{ward} \par III.\ --- \input{ward} \par IV.\ --- \input{ward} \par \stoptext

I cannot seem to figure out why the \clearpage (or anything for that matter) causes the \AtEndDocument hooks to not work. The other two dont seem to ever do anything which likely means I am using them wrong. \documentclass{article} \usepackage{atveryend} \AtEndDocument{\addtocontents{toc}{\protect bla?}} \AfterLastShipout{\addtocontents{toc}{\protect bla??}} \AtVeryEndDocument{\addtocontents{toc}{\protect bla???}} \begin{document} \tableofcontents \section{blub} \clearpage \LogHook{enddocument} \end{document} The output from the log is the same regardless of the \clearpage > Document-level (top-level) code (executed last): > -> \addtocontents {toc}{\protect bla?} Edit: Added photo demonstrating how none of the hooks function as expected.

By coordinate, if it's possible, I want something like (a, b). Or perhaps you have a better way to move the figure freely, please add it to your answer. I don't know where to start and what package I would need, if I need one. Also to make the main document to be cleaner, I don't want any macros from the Tikz. So just leave it there, but include them all. How to do that? T.I.A.

I need to draw three pie-charts side by side e.g. using the pgf-pie package so that the centers of the charts lie on the same imaginary line and are the same distance from each other. Each chart should occupy roughly one third of the \textwidth, but slice labels may overflow the margins. I should also be able to caption each chart individually. So far I only managed to align the three charts but I don't know how to draw them relative to \textwidth and how to caption them: \begin{figure} \centering \begin{tikzpicture} \pie[pos={0,0},radius=2]{30/Label A, 40/Label B, 30/Label C} \pie[pos={5,0},radius=2]{20/Label A, 50/Label B, 30/Label C} \pie[pos={10,0},radius=2]{25/Label A, 25/Label B, 50/Label C} \end{tikzpicture} \caption{Whole figure caption} \end{figure} If I make three distinct tikzpictures, the charts end up misaligned probably due to the slice labels. Any help is appreciated.

\documentclass{amsart} \usepackage{autonum} \begin{document} \begin{align} A_1 = B_1 \label{EQ1} \end{align} \begin{align} A_2 = B_2 \label{EQ2} \end{align} \begin{align} A_3 = B_3 \label{EQ3} \end{align} Using \eqref{EQ1}--\eqref{EQ3} \end{document} I want the last line to run as "Using (1)-(3)". Instead, I get "Using (1)-(2)", since the label for the second equation isn't referenced. Is there a way to fix this without writing tags separately for each equation? This would help since the solution would be flexible to adjust to more equations. (In this example, every equation is numbered. But for the document I am working on, some equations are not numbered as I don't want them to be. That's why I am using autonum.)

I'm using this template to produce posters with columns that are aligned at the bottom. It seems to be based on this solution by Chris Le Sueur.

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