I'm replicating an word documment and need to place some text over an image in the header, but i can't find a simple method to do that.
It's just some text centered over a retangular image, but the best anwser I've found, so far, for doing that is reading an 880 page manual for PFG package.
Is there anyway to do that with some simple package, like minipage?
One possible approach using tikz:
\documentclass{article}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}
\node at (0,0) {\includegraphics[width=6cm]{example-image-duck}};
\node at (current bounding box.center) {Quack};
\end{tikzpicture}
\end{document}

how can I move the current label closer to the current arrow. I.e. I want to move the i_1 closer to the arrow.
MWE:
\documentclass{standalone}
\usepackage[european,cuteinductors,fetbodydiode,straightvoltages]{circuitikz}
\begin{document}
\begin{figure}[htb]
\centering
\begin{tikzpicture}[scale=0.65, arrowmos]
\coordinate (zero) at (0,0);
\draw (zero) to[R,-*,R=$R_1$,i>_=$i_1$] ++(2.75,2);
\end{tikzpicture}
\end{figure}
\end{document}
I tried to put a \vspace in front of the label but it didn't work.
I propose two solutions here: the first one is using a fake label and then setting the label manually (with a lot of flexibility), or using the provided styling for labels. Details in comments; you need a quite recent circuitikz for using this solution (>=1.4.2).
\documentclass{standalone}
\usepackage[european,cuteinductors,fetbodydiode,straightvoltages]{circuitikz}
\begin{document}
\centering
\begin{tikzpicture}[scale=0.65, arrowmos]
\coordinate (zero) at (0,0);
% First option
% use a blank label for the current, and name the component
\draw (zero) to[R,-*,R=$R_1$,i>_=~,name=myI] ++(2.75,2);
% manually place the label where you like
% myIcurrent is the normal position where the blank label is set
\node[below=1mm, anchor=center, red] at (myIcurrent) {$i_1$};
% you can also use bipole current style to change inner sep;
\draw (2,0) to[bipole current style={inner sep=0pt}, R,-*,R=$R_1$,i>_=$i_1$] ++(2.75,2);
\end{tikzpicture}
\end{document}
See circuitikz manual, https://texdoc.org/serve/circuitikz/0#subsection.5.6 .
I would like to add images in the top left/right or bottom left/right in a two-column page while ignoring the margins and having the text wrap around the picture. How can I also extend the solution to include half page images while ignoring the margins and with text wrapping.
I tried tikz package, but the text doesn't wrap around even when I use the wrapfig package.
For example, this is the code I used to insert image on the top left side of the page:
\documentclass[twocolumn, 12pt]{book}
\usepackage{lipsum}
\usepackage{tikz}
\begin{document}
\lipsum[1-3]
\begin{tikzpicture} [remember picture, overlay]
\node[anchor=north west,yshift=-1.5pt,xshift=1pt]%
at (current page.north west)
{\includegraphics[width=0.5\paperwidth,height=0.5\paperheight]{example.jpg}};
\end{tikzpicture}
\lipsum[1-3]
\end{document}
This results in the picture at the desired position, but the text is obscured behind the image. Thank you!
Not very pretty, but does the job I think (using geometry package only to get the correct values for top margin):
\documentclass[twocolumn, 12pt]{book}
\usepackage{lipsum}
\usepackage{tikz}
\usepackage{geometry}
\begin{document}
\begin{tikzpicture} [remember picture, overlay]
\node[anchor=north west]%
at (current page.north west)
{\includegraphics[width=0.46\paperwidth,height=0.5\paperheight]{example.png}};
\end{tikzpicture}
\vspace*{\dimexpr(0.5\paperheight-\voffset-1in-\headsep-\headheight)}
\lipsum[1-3]
\lipsum[1-3]
\end{document}
I am learning Tikz and hope somebody can help me achieve the following i.e. I want to draw a directed arc between objects in an equation. Below is a picture of what I am trying to achieve.
I have also attached the code I have used so far:
\documentclass{article}
\usepackage{amsmath,amssymb,braket,tikz}
\usetikzlibrary{tikzmark,calc}
\begin{document}
\begin{tikzpicture}
$(x+2)(x+3)$
\end{tikzpicture}
\end{document}
I also suspect that there is a way to specify a line or arc, between elements e.g. numbers and letters, without explicitly stating the coordinates. Is this the case? If it were, it would simplify the things I'm trying to achieve.
Any help would be very much appreciated.
The following solution draws an arc above the formula using arc; the actual angles and lengths may have to be adjusted. To get coordinates relative to the formula, the formula is wrapped into the node formula.
\documentclass{article}
\usepackage{amsmath,amssymb,braket,tikz}
\usetikzlibrary{tikzmark,calc}
\begin{document}
\begin{tikzpicture}
\node (formula) [] {$(x+2)(x+3)$};
\draw[-latex,red] ($(formula.north west)+(.4,0)$) arc
[
start angle=160,
end angle=20,
x radius=0.5cm,
y radius =0.5cm
] ;
\end{tikzpicture}
\end{document}
Output:
Another possibility with the tikzmark library:
\documentclass{article}
\usepackage{amsmath,amssymb,braket,tikz}
\usetikzlibrary{tikzmark,calc}
\begin{document}
\begin{equation}
(\tikzmarknode{a}{x}+2)(\tikzmarknode{b}{x}+3)
\end{equation}
\tikz[remember picture, overlay]{\draw[-latex,red] ([yshift=0.1em]a.north) to[bend left] ([yshift=0.1em]b.north);}
\end{document}
I'm trying to draw this in latex.
Anyone know how?
Use the calc-library and do the following:
\usetikzlibrary{calc}
\begin{document}
\begin{tikzpicture}
\node[draw=black, circle, fill=green] (A) at (0,0) {A};
\draw let \p1=(A) in (A) -- (\x1+40,\y1+10);
\end{tikzpicture}
\end{document}
Using the let-statement it allows you to specify a reference point (or even more) to use it's coordinates for further calculation.
I put two image.png in my latex documnet using \includegraphics. Now I want to joint two points of these images together by a line. I wonder if it is possible to do so in Latex?
First: no it is impossible: as Gyro Gearloose had said LaTeX has no idea about the content of your png.
Second: sure you can ;-) A little cheat with tikz. You can connect two arbitrary points with an arrow (or a line).
\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[english]{babel}
\usepackage{lipsum}
\usepackage{pgfplots}
\usepackage{tikz}
\usetikzlibrary{positioning}
\usetikzlibrary{tikzmark} % arrows in tex
\usetikzlibrary{arrows} % arrows in tex
\usetikzlibrary{calc} % (node)+(3cm,2cm)
\tikzstyle{every picture}+=[remember picture]
\begin{document}
\lipsum[1]
\includegraphics[width=0.2\textwidth]{solidtex.png}
{\tikz\node[coordinate](start1){};}
\lipsum[2]
{\tikz\node[coordinate](end1){};}
\includegraphics[width=0.2\textwidth]{solidtex.png}
\lipsum[3]
\begin{tikzpicture}[overlay, remember picture, -latex, color=blue!15!red, yshift=1ex, shorten >=1pt, shorten <=1pt, line width=0.1cm]
\path[->] (start1) edge [out=150, in=240] (end1);
\end{tikzpicture}
\end{document}
But it still connects the corners of the images. To connect points inside the pictures, you have to modify the coordinates manually e.g.:
\path[->] (start1) edge [out=150, in=240] ($(end1)+(2cm,2cm)$);
or pt, ex, mm ect...
If you want line without arrow head, use:
\path[-] (start1) edge [out=150, in=240] (end1);
Note that like labeling and referring figures, you have to run latex (or pdflatex or ...) twice.
