symbols
\clubsuit, \diamondsuit and the like produce the familiar card suit symbols; however, the diamond and heart suits are empty (only outlined), while clubs and spades are filled. Is there a way to obtain the filled versions of \diamondsuit and \heartsuit in TeX?
A "clean" solution would be preferred, but even an ugly "take this shape and fill it" TikZ hack would do the job.
Not the best macro in the world, but perhaps something like
\usepackage{tikz}
\newcommand{\pie}[1]{%
\begin{tikzpicture}
\draw (0,0) circle (1ex);\fill (1ex,0) arc (0:#1:1ex) -- (0,0) -- cycle;
\end{tikzpicture}%
}
And an example
Hello world \pie{90} \pie{120} \pie{240} \pie{270}
Output:
Here's the \ooalign black magic:
\documentclass{article}
\usepackage{amssymb}
\newcommand{\bleq}{\mathrel{\mathpalette\bleqinn\relax}}
\newcommand{\bleqinn}[2]{%
\ooalign{%
\raisebox{.2ex}{$#1\blacktriangleleft$}\cr
$#1\leq$\cr
}%
}
\begin{document}
$a\bleq b\leq c$
$\bleq_{\bleq_{\bleq}}$
\end{document}
