\title{\texttt{xfakebold}, v. 0.04\\ using bold characters with \texttt{pdflatex} or \texttt{lualatex}}

\begin{abstract}
The package fakes a vector font with outline characters by the text render of PDF.
It writes directly into the pdf output with \verb|\pdfliteral| (pdflatex ) or \verb|\pdfextension| \verb|literal|
(lualatex). The package defines two macros which can be used in text and in math mode. However, for the text
mode one should use the bold version of the text font which should be available in most cases. This is different to the
math mode where only some free math fonts provide a bold version.

\section{How does it work?}
PDF knows different text render modes for outline fonts.
\def\OFF{\pdfextension literal direct { 0 Tr 0 w }\relax}
\def\Verb|#1|{\texttt{\{#1\}}}
\makebox[3cm][l]{Mode 0 \Verb| 0 Tr 0 w |} \tabular{l}\pdfextension literal direct { 0 Tr 0 w }\scalebox{10}{OTTO} OTTO\OFF\endtabular
\makebox[3cm][l]{Mode 1 \Verb| 1 Tr 0 w |} \tabular{l}\pdfextension literal direct { 1 Tr 0 w }\scalebox{10}{OTTO} OTTO\OFF\endtabular
\makebox[3cm][l]{Mode 1 \Verb| 1 Tr 0.3 w |} \tabular{l}\pdfextension literal direct { 1 Tr 0.3 w }\scalebox{10}{OTTO} OTTO\OFF\endtabular
\makebox[3cm][l]{Mode 2 \Verb| 2 Tr 0 w |} \tabular{l}\pdfextension literal direct { 2 Tr 0 w }\scalebox{10}{OTTO} OTTO\OFF\endtabular
\makebox[3cm][l]{Mode 2 \Verb| 2 Tr 0.3 w |} \tabular{l}\pdfextension literal direct { 2 Tr 0.3 w }\scalebox{10}{OTTO} OTTO\OFF\endtabular
In mode 0 the character is filled but without drawing its outline which can be seen when printing in mode 1, where
the linewidth of the outline is the smallest one which the system allows. Setting the linewidth to 0.3\,bp, which is
nearly the same as 0.3\,pt, the linewidth of the outline increases. In mode 2 the character is printed with filling \emph{and}
drawing the outline, which is mode 0 and 1 together. The reason why the character is bold by default. Increasing the linewidth
makes it more bold.
\section{Optional argument}
The only package option is \verb|bold| which is preset by 0.3, which is the linewidth of
the outlines of the characters.

\usepackage[bold=0.6]{xfakebold}

makes the characters more bold.
