Since the July 1st, 2019 release of the LaTeX3 kernel, the driver-specific code contained in the l3backend module was moved to a dedicated package in CTAN, and now l3backend is a dependency of l3kernel. The description of l3backend on CTAN says: The func­tions here are de­fined dif­fer­ently de­pend­ing on the en­gine in use. As such, these are dis­...

You were on the right track trying to renew \@venn@shade but to do that you need to wrap the \renewcommand in \makeatletter \makeatother. See What do \makeatletter and \makeatother do? You can also modify aspects of the tikzpicture environment used to draw the venn diagram by using the option tikzoptions=. In this way you can modify the colour of the lines ...

In fdsymbol.sty there are no slot numbers and one has to count manually. One finds \fdsy@setslot{0} \fdsy@DeclareSymbol{\rightarrow}{arrows}{\mathrel} which means \rightarrow is at slot 0 of the arrows symbol font. Looking for your desired symbol and counting yields that \leftrightarrow is at slot 16 \updownarrow is at slot 17 \neswarrow is at slot 18 \...

Please note that you got a new command center for MiKTeX with the new version: MiKTeX Console. It includes all configuring tools together in one tool: The old package manager you can get with clicking on Packages (see red arrow, marked 3), the old update manager you can get with Updates (red arrow, 2) or just click on check for updates at the end of the ...

use this code!!! const string latex = @"\frac{2+2}{2}"; const string fileName = @"formula.png"; File.Open(fileName, FileMode.OpenOrCreate).Close(); var parser = new WpfMath.TexFormulaParser(); var formula = parser.Parse(latex); var renderer = formula.GetRenderer(WpfMath.TexStyle.Display, 20.0, "Arial"); var bitmapSource = renderer.RenderToBitmap(0, 0); ...

Your code works fine with me but not centered. Also you don't need to add "**" beside the command. Try this one: \documentclass{article} \usepackage{graphicx} \begin{document} \begin{figure}[ht] \centering \includegraphics[width=3.0in]{example.png} \caption{write your caption here} \label{write your label here} \end{figure} ...

Using TiKz without using enumerate. \documentclass[a4paper,12pt]{article} \usepackage{fontawesome} %\usepackage{enumitem} \usepackage{xcolor} \usepackage{tikz} \newcommand{\myenum}[4]{ \begin{tikzpicture} \begin{scope} \node at (0,0) (bat1) {\textcolor{green}{\faBatteryFull}}node[right=5mm]{#1}; \end{scope} \begin{scope}[shift={(0,-1)}] \node at (0,0) (bat2)...

Well, to avoid in future such issues why do you not simply install the complete MiKTeX? Then pgf/Tikz is included ... Please see that the current version of MiKTeX pdfTeX, Version 3.14159265-2.6-1.40.20 (MiKTeX 2.9.7050 64-bit) has a new MiKTeX Console instead your old shown MiKTeX Package manager. I recommend you update your system, and then use MiKTeX (...

After a bit more fiddling I was able to fix the problems Correction 1: Removed y dir=reverse. Correction 2: From the line \pgfmathfloatifflags{\pgfmathresult}{0}{\hspace{-0.75ex}0}{x}% I removed \hspace{-0.75ex} as noted in the comments. I still need to figure out how give the dfrac a bit more space Code \documentclass{article} \usepackage{pgfplots} \...

Hm, this issue can have three parts, I guess: Did you install as admin MiKTeX, but added the localtexfm as user? Do you have writing rights for your localtexfm directory: C:\Files\MikTex\localtexmf? You have a broken MiKTeX installation. Open MiKTeX Console as administrator and click on Settings. Then you should see something like that after clicking on ...
