# Non-bitmapped “thumb up” symbol for flagging “good practice” tips

I want to use a "thumb up" symbol, to flag a "good practice" tips in my document. Table 244 in the Comprehensive LaTeX Symbol list shows that the dingbat package provides the following:

However, the symbol is bitmapped and doesn't render well when zoomed in on, which I dislike:

Do you know of a similar, non-bitmapped symbol? Otherwise Feel free to suggest an alternative symbol that conveys the same meaning.

Go to FB! :P Ok, joke aside, you could create or get a vector graphic and use the picture as a symbol, see here: tex.stackexchange.com/questions/22487 or here: tex.stackexchange.com/questions/31490 –  Count Zero Jun 15 '13 at 11:19
Obligatory Unicode suggestion: U+1F44D: 👍 (naturally needs a font which includes the glyph) –  morbusg Jun 15 '13 at 11:46
You are very well capable of writing up the 8-10 lines in tikz for that. Rounded corners for the fingers :P –  percusse Jun 15 '13 at 12:03

A free SVG version can be found on Wikimedia: Symbol thumbs up. The file Symbols_thumbs_up.svg can be converted with Inkscape to PDF like in this answer:

inkscape --export-pdf=Symbol_thumbs_up.pdf Symbol_thumbs_up.svg


The white margins can be removed by pdfcrop:

pdfcrop Symbol_thumbs_up.pdf


The result is Symbols_thumbs_up-crop.pdf.

In LaTeX it can be included, mirrored and resized by package graphicx with a driver that supports PDF. Otherwise it can be converted to EPS via pdftops of xpdf or poppler:

pdftops -eps Symbols_thumbs_up-crop.pdf Symbols_thumbs_up.eps


LaTeX example that defines \LeftThumbsUp and \RightThumbsUp:

\documentclass{article}
\usepackage{graphicx}

\newcommand*{\RightThumbsUpAux}[1]{%
\begingroup
\sbox0{Ag}%
\raisebox{-\dp0}{%
\includegraphics[{%
height=\dimexpr\dp0+\ht0\relax,
#1%
}]{Symbol_thumbs_up-crop.pdf}%
}%
\endgroup
}
\newcommand*{\RightThumbsUp}{%
\RightThumbsUpAux{}%
}
\newcommand*{\RightThumbsDown}{%
\RightThumbsUpAux{origin=c,angle=180}%
}
\newcommand*{\LeftThumbsUp}{%
\scalebox{-1}[1]{\RightThumbsUp}%
}
\newcommand*{\LeftThumbsDown}{%
\scalebox{-1}[1]{\RightThumbsDown}%
}

\begin{document}
\begin{tabular}{ll}
\LeftThumbsUp    & \verb|\LeftThumbsUp|\\
\RightThumbsUp   & \verb|\RightThumbsUp|\\
\LeftThumbsDown  & \verb|\LeftThumbsDown|\\
\RightThumbsDown & \verb|\RightThumbsDown|
\end{tabular}
\end{document}

Just to be picky: The thumb symbols are normally displayed from the agent's perspective, so the thumbs down symbols should have their palms hidden. –  Sverre Jun 15 '13 at 13:39
@Sverre My impression from a quick web search was: Most images show the fingers, some shows the front view (front of the thumb), and images with the fingers hidden are quite rare. –  Heiko Oberdiek Jun 15 '13 at 13:55
When doing a google images search for "thumbs down", my impression is that the split is about 50-50. I personally prefer the thumbs down symbols where the palm is hidden, since this would be consistent with the visible palm in the thumbs up symbols (= they are all seen from the agent's perspective). But this is a minor point - I just wanted to call your attention to it in case you (or someone else) cared. –  Sverre Jun 16 '13 at 12:15
