![]() | ![]() | ![]() | 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:
You can color your bullets:
<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"/> </gradient> <symbol name="sphere"> <path matrix="0.04 0 0 0.04 0 0" fill="blue" gradient="ball"> 18 0 0 18 0 0 e </path> </symbol> <preamble> \def\labelitemi{\raisebox{0.5ex}{\hbox to 0.3em{\ipesymbol{sphere}{}{}{}}}} </preamble>
