I try to reproduce the answer Photo Clipper of kiss my armpit to the question Photo Clipper but it is not succeeding. As I do not have any clue what might be the problem I would like to know if there is anything I have to take into account to get the desired result (such as picture size...):
\documentclass[border=12pt,pstricks]{standalone}
\usepackage{graphicx}
\newsavebox\IBox
\savebox\IBox{\includegraphics{pretty}}
\usepackage{pst-plot}
\def\x(#1){sin(#1)^3}
\def\y(#1){(13*cos(#1)-5*cos(2*#1)-2*cos(3*#1)-cos(4*#1))/16}
\psset
{
algebraic,
plotpoints=100,
xunit=.5\wd\IBox,
yunit=.5\ht\IBox,
}
\usepackage{mathtools}
\begin{document}
\begin{pspicture}[showgrid=false](-1,-1)(1,1.5)
\begin{psclip}{\psparametricplot[origin={0,0.15}]{0}{\psPiTwo}{\x(t)|\y(t)}}
\rput(0,0){\usebox\IBox}
\end{psclip}
\rput(0,1.25){%

$\displaystyle\!
\begin{aligned}
% x(t)&=\sin^3 t\\
% y(t)&=(13\cos t -5\cos 2t -2\cos 3t -\cos 4t)/16
\end{aligned}$}
\rput(0,1){
%HAPPY BIRTHDAY
}
\end{pspicture}
\end{document}

pretty.png(or .jpg or any other that is accepted by\includegraphics? Have you tried the options of\includegraphicssuch as[scale=]or[width=\textwidth]? (4kg of potatoes? You must be german) – Huang_d Jun 12 '17 at 12:28[scale=]and[width=\textwidth], but it does not work. (I am:-)) – Philip Jun 12 '17 at 14:46[noisy]option. I can't verify your problem here. Are you running Lua-, La-, Xe-, XelaTeX? The manual says: "You cannot run your files with pdftex/pdflatex/luatex/lualatex, use xetex/xelatex instead or the sequence latex->dvips->ps2pdf" (from here: https://www.tug.org/PSTricks/main.cgi/ ) Please provide more information. – Huang_d Jun 12 '17 at 15:38l.22...rigin={0,0.15}]{0}{\psPiTwo}{\x(t)|\y(t)}}`
