#Packages#

\latex, in addition to its predefined commands, has a big number of packages
that increase its power. \hatex functions for some of these packages are defined
in separated modules, one module per package. This way, you can import only those
functions you actually need. Some of these modules are below explained.

##Inputenc##

This package is of vital importance if you use non-ASCII characters in your document.
For example, if my name is /Ángela/, the /Á/ character will not appear correctly in the
output. To solve this problem, use the \{Inputenc\} module.

\[
import Text.LaTeX.Base
import Text.LaTeX.Packages.Inputenc

thePreamble :: LaTeX
thePreamble =
    documentclass [] article
 <> usepackage [utf8] inputenc
 <> author "Ángela"
 <> title "Issues with non-ASCII characters"
\]

Don't forget to set to UTF-8 encoding your Haskell source too.

##Graphicx##

With the \{Graphicx\} package you can insert images in your document and do some
other transformations. In order to insert an image use the \{includegraphics\}
function.

\[
includegraphics :: LaTeXC l => [IGOption] -> FilePath -> l
\]

The list of \{IGOption\}'s allows you to set some properties of the image, like width,
height, scaling or rotation. See the API documentation for details.
