7.5 Ipe symbols used from text objects

## 7.5 Ipe symbols used from text objects

Presentations often make use of itemize environments. You can make these prettier in a number of ways:

<preamble>
\def\labelitemi{\LARGE\textcolor{red}{$\bullet$}}
</preamble>


Enumeration numbers could be put in a colored box:

<preamble>
\newcommand{\labelenumi}{\fbox{\Roman{enumi}}}
</preamble>


You could use the Dingbats font for nice enumerations, for instance by putting \usepackage{pifont} in your preamble, and then having text objects with \begin{dinglist}{43} or \begin{dingautolist}{172} (or use 182, 192, 202 for various circled numbers).

You can mark items as "good" and "bad" using these "bullets":

Bad item: \textcolor{red}{\ding{55}}
Good item: \textcolor{green}{\ding{52}}

Finally, you can custom design your own bullets by creating an Ipe symbol for it. For instance:

<symbol name="bullet(sfpx)">
<path matrix="2 0 0 2 0 0" pen="sym-pen" stroke="sym-stroke" fill="sym-fill">
0 0 m -1.0 0.333 l -0.8 0 l -1.0 -0.333 l h</path>
</symbol>
<preamble>
\def\labelitemi{\raisebox{0.5ex}{\hbox to 0.3em%
{\ipesymbol{bullet(sfpx)}{blue}{yellow}{normal}}}}
</preamble>


Note the use of the \ipesymbol{name}{stroke}{fill}{pen} command. It allows you to use an Ipe symbol from inside a text object. The symbol is magnified proportionally to the ex-height of the current font at the position where it is used. (And so the symbol should be designed to be the correct size for a font of ex-height 1pt.)

In the following example, we redefine the bullet to be a blue glassy sphere:

<gradient name="ball" type="radial" coords="-4 10 2 0 0 18">
<stop offset="0" color="1 1 1"/>
<stop offset="1" color="0 0 1"/>
