Launcher icon using latex

Question

Is there a package that compiles a latex image to an icon of Launcher for Android while maintaining screen densities? For this in Android Studio there is Image Asset Studio, but no I manage to recreate the desired icon image.

Edited: In the following image marked with arrows shows the Launcher Icon, I used the tikzpeople package, but the sharpness and resolution of the image is not good.

enter image description here

@AndréC When an app installed, an icon appears on the screen, for example, the WhatsApp icon is green with a phone drawing enclosed in a bubble. — Samuel Diaz, Jan 13 '19 at 14:17

This is exactly what tikzpeople does. This is the title of the package documentation:

And here is the code for the picture:

\documentclass[tikz,margin=3mm]{standalone}
\usepackage{tikzpeople}
\begin{document}
\begin{tikzpicture}
    \node[graduate,shield,sword] {};
\end{tikzpicture}
\end{document}

If you look at the silhouette of the pic, you may discover a duck in it. ;-) (+1) – Jan 13 '19 at 16:10

You're not crediting CarLaTeX for saying the same thing in his commentary? – AndréC Jan 13 '19 at 16:11

Yes, but what I meant is this. ;-) – Jan 13 '19 at 16:29

@marmot A note to the duck: Take care or the sword will harm you :)) – Jan 13 '19 at 16:32
Joking aside the REQUIREMENT is ideally SVG output since the OP already has that raster as his startpoint @marmot your an export :-) on Tikz – Jan 13 '19 at 16:56

As svg seems to be the wanted end format, you should add the dvisvgm option, and compile with latex + dvisvgm. – Ulrike Fischer Jan 13 '19 at 17:08

For those interested, here is a silhouette of it: https://i.stack.imgur.com/Msqb4.png. – Solomon Ucko Jan 13 '19 at 19:02
@SolomonUcko Yes, a duck. ;-) – Jan 13 '19 at 19:24
@UlrikeFischer I suggest not to use the dvisvgm option when compiling with latex + dvisvgm because it often produces odd results. Instead, the default options as in the above example (implying dvips) should work just fine with dvisvgm. – Martin Jan 14 '19 at 08:06

Putting "Icons" into the packages search field on CTAN produces 17 hits

Interestingly one includes Knuth's own input

but only a few are close to your request for modern App stylised output.

None will provide the android recommended / required res structure.

App studio recommends an SVG input, See Ulrike Fischer's comment as to how this may be achieved via latex + dvisvgm. however I found this produced an odd translucent result

Ignore the crude graphic note by default the collar is showing through the face

For Martin Scharrer's pdf2svg tikzpicture method see /try his answer at https://tex.stackexchange.com/a/51766/170109
however I had problems running interactively so using on command line

I got a better opaque result (to produce this output, note it is the larger drawable-xxxhdpi since I cant upload the .svg)

So here is the code

\documentclass[crop,tikz,convert=pdf2svg]{standalone}
\usepackage{tikzpeople}
\begin{document}
\begin{tikzpicture}
    \node[graduate,saturated,mirrored,monitor,undershirt=yellow] {};
\end{tikzpicture}
\end{document}

via this sequence

Latex logo.tex
pdf2svg logo.pdf logo.svg

A windows version can be found here https://github.com/jalios/pdf2svg-windows/releases

And here it is loaded in Asset Studio and the download res file with 5 perfect images will be about 55KB (well lean! 130 if you include web version)

Whatever TeX / TikZ / SVG output takes your fancy. (that last one is blochsphere)

Alternately the icon you have identified and as shown in the answer by JouleV can be modified to suit a suite of the recommended pixel sizes.

The key to pixel sharpness is choosing a large enough scale that works for Hi-Res and can be divided down to smaller sizes, whilst retaining clarity in an application such as inkscape. The set of manually reduced icons can then be loaded and modified in Image Asset Studio to add the desired rounding etc.
