Draw zodiac sign leo

Question

tikz community,

after hours of seeking a solution to draw the zodiac sign leo I realize that I cannot deal with finding control points to get a wished curve. I tried bend-to and others, no result. I have fixed approx coordinates to show the idea of the wished line. Can anyone help? I do not add a photo because of copyrights, but I think there is no difficulty to get an image of this sign beyond artistic freedom. If possible I want to do it in tikz.

The mwe ist somewhat rediculous. As I have said, I cannot realize it.

Answer 1

Several fonts have astronomical symbols. In general you can consult the Comprehensive LaTeX Symbol List, which, even though it is quite long, is easily searchable. You'll find the characters of interest in Tables 325–331.

With \usepackage{starfont} the command \Leo produces:

With wasysym the command is \leo:

marvosym has \Leo:

The package utfsym has \usym{264C}:

Answer 2

A quick start point could be:

\documentclass[tikz,border=2mm]{standalone}
\begin{document}
\begin{tikzpicture}[line width=2mm]
  \draw (0,0) circle (1);
  \draw (30:1) to[out=120,in=270] (0.5,2) to[out=90,in=180] (1.5,3) to[out=0,in=90] (2.5,2) to [out=270,in=180] (2.5,-2) arc (270:315:1);
\end{tikzpicture}
\end{document}

Answer 3

The finished.

Example 4: From http://tug.ctan.org/info/symbols/comprehensive/symbols-a4.pdf

in Table 330, the statement All utfsym symbols are implemented with TikZ graphics, not with a font, so, if your symbol is not a font, then of course texpath will not be able to describe it. It means that texpath does not work for the utfsym package or similar packages!

From CarLaTeX's comment.

If you know Asymptote, you will find that it has several amazing commands!

The command is path[] texpath(Label L) (the path array that TEX would fill to draw the Label L.). You can test many other LaTeX symbols.

usepackage("wasysym");
size(350,0);
path[] g=texpath("\leo");
write(g.length); // Outputs: 2
filldraw(g[0],cyan+green,red+dashed+.8bp);
filldraw(g[1],gray,blue+1.5bp);
write(cyclic(g[0])); // Outputs: true
write(cyclic(g[1])); // Outputs: true
arrow("the red and dashed path ",relpoint(g[0],0.78),dir(90));
arrow("the blue path which has the linewidth is 1.5bp",relpoint(g[1],0),dir(-90));

or with \cancer

usepackage("wasysym");
size(350,0);
path[] g=texpath("\cancer");
write(g.length); // Outputs: 4
filldraw(g[1],gray,blue+1.5bp);
filldraw(g[0],cyan+green,red+dashed+.8bp);
filldraw(g[3],gray,blue+1.5bp);
filldraw(g[2],cyan+green,red+dashed+.8bp);
write(cyclic(g[0])); // Outputs: true
write(cyclic(g[1])); // Outputs: true
write(cyclic(g[2])); // Outputs: true
write(cyclic(g[3])); // Outputs: true

You can handle the curves manually!

RUN Asymptote codes in Notepad++ on MSWindows system.

Step 1: Install Notepad++.

Step 2: Install TeXLive (recommended by Asymptote's authors), Adobe Acrobat Reader DC, Asymptote (latest version), Ghostscript (stable version), ImageMagick (stable version).

Step 3: Add two following files:

asy.xml is belong to ..\Notepad++\autoCompletion

userDefineLang.xml is belong to ..\PC\AppData\Roaming\Notepad++

To update new commands, see following links:

https://code.google.com/archive/p/asy4cn/downloads (in Chinese) https://asy.marris.fr/forum/viewtopic.php?t=148 (in French)

Sorry, my native language is Vietnamese, I also know a little English.

These are my several pictures after installing successfully.

Run latexusage.tex in TeXstudio:

Like this, the file name is document.tex

You run step by step as follows:

1. Tools --> Commands --> PDFLaTeX, the output like this
2. Tools --> Commands --> Asymptote, the output like this
3. Tools --> Commands --> PDFLaTeX, done.

The completed file lies in C:\Users\PC\Downloads as in attached images.

You can also choose http://asymptote.ualberta.ca/ to compile Asymptote code online.

You must compile any Asymptote codes successfully, then you can start with Asymptote.

You can try to install Notepad++ on Linux! If done, feel free to update this answer.

To make clear my opinion You can handle the curves manually!:

Example 1: Can I visualize the Bezier control points of a letter ... in TeX?

Example 2: Animated filling of a font character

Example 3:

// settings.render=8;
unitsize(1cm);
import texcolors; // for pens like CornflowerBlue, Goldenrod,Bittersweet, Melon
texpreamble("\usepackage{starfont}");
path[] h=texpath("\Leo");
// To know the number of paths of Label L in texpath
write(h.length); // Outputs: 2
fill(h[1],pink+opacity(.5));
filldraw(h[0],CornflowerBlue,red+1.5bp); 
pair[] P;

for(int j=0;j<size(h[0]);++j){ P.push(point(h[0],j)); } 
pair interpoint=extension(P[0],P[2],P[1],P[3]); 
for (int j=0; j<P.length; ++j){ 
  dot("$P["+(string) j+"]$",P[j],dir(j90)); 
}

filldraw(shift(interpoint)scale(0.75)shift(-interpoint)h[0],CornflowerBlue+yellow,red+1.5bp);
real[] c=uniform(0,length(h[1]),5);
write(c); // Outputs: {0,4,8,12,16,20}
c.cyclic=true;
pen[] pp={YellowGreen+dashdotted+1bp,blue+dashed+1bp,dotted+1.5bp,Goldenrod+0.6bp,Bittersweet+0.7bp,Melon+0.8bp};
for (int i=0; i<c.length-1; ++i)
  draw(subpath(h[1],c[i],c[i+1]),pp[i],Arrow(size=10));
draw((0,0)--(5,0),Arrow);
draw((5,0)--(-5,4),Arrow);
dot("$(0,0)$",(0,0),dir(90));
dot("$(5,0)$",(5,0),dir(0));
dot("$(-5,4)$",(-5,4),dir(90));
pair[] interpoints=intersectionpoints(h[1],(0,0)--(5,0)--(-5,4),sqrtEpsilon);
write(interpoints.length); // Outputs: 6
dot("$A$",interpoints[0]);
dot("$B$",interpoints[1]);
dot("$C$",interpoints[2]);
dot("$D$",interpoints[3]);
dot("$E$",interpoints[4]);
dot("$F$",interpoints[5]);

Answer 4

Inspired from Asymptote's service representing a glyph's bezier control points(BCP) I was able to reproduce curves with approximately correct BCPs. Mathematically unfamiliar it was a great help to see Asymptote's delivery of BCPs. So a good answer seems to be: "Take a book of mathematics or train your use of control points.".

Unsolved is the point 25 at (0,0) of a foreach loop and the unability to fill the drawn area. Should I ask a new question?
