The 3.0 release gets:


\begin{itemize}
	\item New math accents, \verb+\widearc+, \verb+\widearcarrow+, \verb+\wideparen+, \verb+\widering+,
                        design of \verb+\widehat+ accent slightly altered;
	\item New width of integral symbols, slighty increased;
	\item New option \texttt{widermath} with obvious action;
	\item Subscript and superscript position revisited in all math alphabets;
	\item Kerning revisited in all text fonts.
\end{itemize}

\begin{center}
\textit{The two last can alter your typesetting!}
\end{center}

The 3.01 release corrects the \verb=\pounds= bug in math mode, and the 3.02 the \verb=\questiondown= bug.

\section{Kp-Fonts}

\subsection{What is Kp-Fonts?}

Kp-Fonts provides a full set of fonts for LaTeX typesetting, including roman, sans-serif et fixed-width fonts, as well as a set of mathematics symbol fonts with, regular and bold, all the common symbols and all those of the \textsc{ams} and more\dots

The typical feature of these fonts is to have a basic and dynamic shape. For instance, look at the roman upright "a" glyphs:

\bigskip

\hspace{-6mm}\begin{tabular}{|c|c|c|c|c|c|}\hline
Kp-Fonts & Kp-\textit{light} & CM & Palatino & Utopia & Times\\\hline
\scalebox{10}{a} &
\scalebox{10}{\fontfamily{jkpl}\selectfont a} &
\scalebox{10}{\fontfamily{lmr}\selectfont a} &
\scalebox{10}{\fontfamily{ppl}\selectfont a} &
\scalebox{9.2}{\rule{0pt}{1.25ex}\fontfamily{put}\selectfont a} &
\scalebox{10}{\fontfamily{ptm}\selectfont a}\\\hline
\end{tabular}

\bigskip

The project is to provide a large set of options to customize your math or text typesetting.

\medskip

This LaTeX package is distributed with a \textsc{gpl} licence.

\medskip

Kp-Fonts doesn't require any other font package and is fully compatible with \texttt{amsmath} and \texttt{textcomp}
with the \texttt{full} option. Kp-fonts loads these two packages except if you use relative options.
 
\begin{center}
\textit{You haven't to load \textbf{\texttt{amsmath}} and \textbf{\texttt{textcomp}} packages}
\end{center}

To use it, you just have to add \verb+\usepackage{kpfonts}+ in your document preamble, if necessary with the options described below.

Besides, the aim is to get a good compatibility with different sets of math font packages.

\subsection{Text fonts}

\begin{itemize}
  \item The encodings \textsc{t1, ot1} et \textsc {ts1} are fully available, except for the uppercase symbol \verb+\SS+ in teletype fonts; if you use some accents, you have to work with \textsc{t1} encoding, \textsc{ot1} is present for historical compatibility;
  \item Roman fonts are available with upright, small caps, italic, slanted, small caps slanted and oldstyle shape, all with regular, bold and bold extended weight;
  \item Sans-serif fonts are available with upright and slanted, small caps upright and slanted shape, and oldstyle all with regular, bold and bold extended weight;
  \item Teletypes fonts are available with upright and slanted shape, all with regular and bold weight;
\end{itemize}

\begin{center}\itshape
The default weight is \textbf{bold}, not \textbf{bold extended}.
\end{center}

\subsection{Math fonts}

\begin{itemize}
	\item The \verb+\boldmath+ command is fully installed and Kp-Fonts \textbf{doesn't need} "poor man bold" glyphs;
	\item Kp-Fonts provides upright and slanted greeks: $\alphaup\betaup\gammaup\Gamma\Delta$ and $\alpha\beta\gamma\Gammasl\Deltasl$;
	\item \verb=\mathbb= provides $\mathbb{ABC}$, characters designed from capital upright roman;  
	\item \verb=\mathcal= provides $\mathcal{ABC}$, slighty altered fonts from \textsc{cm};
	\item With \verb=\mathscr=, you get $\mathscr{AB}\,\mathscr{C}$, without any extra package; these letters are designed from traditional fonts;
	\item \verb=\mathfrak= provides $\mathfrak{ABCabc}$, still from traditional fonts, altered to be more readable:
	read $\mathfrak{CTAN}$ and \textit{CTAN} in \texttt{www.ctan.org}!
\end{itemize}

\section{Options}

\subsection{Main global options}

\begin{description}
	\item[light:] then, you use the light version of the fonts. The metrics are the same. 
									The display is not very good, but the print is fine if you like light fonts;
	\item[fulloldstylenums:] equivalent to both \texttt{oldstylenums}
	
			  and \texttt{oldstylenumsmath};
	\item[fulloldstyle:] equivalent to both \texttt{oldstyle} and \texttt{oldstylemath};
	\item[fullveryoldstyle:] equivalent to both \texttt{veryoldstyle} 
				
				and \texttt{veryoldstylemath}.
\end{description}

This text is typesetted with default fonts, and below you can see an example of the light fonts set, upright and italic, both regular and bold :\medskip

\hfill\begin{minipage}{11cm}{\fontfamily{jkpl}\selectfont
While the high-level font commands are intended for use in a document, the low-level commands\dots

\hfill\begin{minipage}{11cm}{\fontfamily{jkpl}\selectfont
\textbf{\textit{While the high-level font commands are intended for use in a document, the low-level commands\dots}}
}\end{minipage}

\subsection{Other global options}

\begin{description}
	\item[nomath:] Kp-Fonts doesn't modify default mathematical fonts;
	\item[notext:] Kp-Fonts doesn't modify default text fonts;
	\item[nosf:] Kp-Fonts doesn't modify default sans serif fonts (text and math);
	\item[nott:] Kp-Fonts doesn't modify default fixed width fonts (text and math);
	\item[onlyrm:] equivalent to the last two options;
	\item[noamsmath:] Kp-Fonts doesn't load \textit{amsmath} package; 
	\item[notextcomp:] Kp-Fonts doesn't load \textit{textcomp} package.
\end{description}

With both the two first and two last options, Kp-Fonts does nothing\dots


\subsection{Text fonts options}

These options affect only text fonts.

\begin{description}

	\item[oldstylenums:] provides here
		oldstyle numbers by default. 
		
		A new command \verb=\classicstylenums= allows you to get usual numbers in roman fonts.
		
		Some examples, upright and italic, medium and bold:
		
			\begin{itemize}
				\item {\fontfamily{jkposn}\selectfont 0123456789 !}
				\item {\fontfamily{jkposn}\selectfont \textit{0123456789 !}}
				\item {\fontfamily{jkposn}\selectfont \textbf{0123456789 !}}
				\item {\fontfamily{jkposn}\selectfont \textbf{\textit{0123456789 !}}}
			\end{itemize}

	\item[oldstyle:] provides here {\fontfamily{jkpos}\selectfont "Q"}, 
		and oldstyle numbers by default. 
		
		With roman and sans-serif fonts, you get the old ligatures {\fontfamily{jkpos}\selectfont "ct"} 
		and {\fontfamily{jkpos}\selectfont "st"}.
		Oldstyle also provides the small capital  {\fontfamily{jkpos}\selectfont "\textsc{q}"}.
		
		A new command \verb=\classicstylenums= allows you to get usual numbers in roman fonts.
		
		Some examples:
		
			\begin{itemize}
				\item {\fontfamily{jkpos}\selectfont Queer font, queer actual aesthetic!}
				\item {\fontfamily{jkpos}\selectfont \textit{Queer font, queer actual aesthetic!}}
				\item {\fontfamily{jkpos}\selectfont \textbf{Queer font, queer actual aesthetic!}}
				\item {\fontfamily{jkpos}\selectfont \textsc{Queer font, queer actual aesthetic!}}
				\item {\fontfamily{jkpos}\selectfont \textbf{\textit{Queer font, queer actual aesthetic!}}}
				\item {\fontfamily{jkpos}\selectfont \textsc{\textbf{Queer font, queer actual aesthetic!}}}
			\end{itemize}
			
	\item[veryoldstyle :] Same as the \texttt{oldstyle} option except the round "s"
		is replaced with the long "{\fontfamily{jkpvos}\selectfont s}\,".
		
		You can get the round "s" using the ligature "\texttt{s=}", often used at the end of the word.
		
		Example: \verb+\textit{costs=}+\quad gives \quad "{\fontfamily{jkpvos}\selectfont \textit{costs=}}"
		
		Obviously, there is no long "{\fontfamily{jkpvos}\selectfont s}\," in smallcaps shape!
		
	\item[rmx] then , you get six weights, with the correponding fonts:
	
	\medskip
	
	\begin{tabular}{|c|c|c|}\hline
		light & \texttt{l} & {\fontfamily{jkpx}\fontseries{l}\selectfont medium in light mode} \\ \hline
		medium & \texttt{m} & {\fontfamily{jkpx}\fontseries{m}\selectfont medium in default mode} \\ \hline
		semi-bold & \texttt{sb} & {\fontfamily{jkpx}\fontseries{sb}\selectfont bold in light mode} \\ \hline
		bold & \texttt{b} & {\fontfamily{jkpx}\fontseries{b}\selectfont bold in default mode} \\ \hline
		semi-bold extended & \texttt{sbx} & {\fontfamily{jkpx}\fontseries{sbx}
													\selectfont bold extended in light mode} \\ \hline
		bold extended & \texttt{bx} & {\fontfamily{jkpx}\fontseries{bx}
																		\selectfont bold extended in default mode} \\ \hline
	\end{tabular}
	
	\medskip
	
	In this case, the \textit{light} option affects only math fonts.
	
	This option is not my favorite because the default and light families are cousins but not sisters.

	This option affects only roman fonts.
	
	\item[largesmallcaps] gives larger small capitals than default:
	
				{\fontfamily{jkpk}\selectfont\textsc{Large}} and \textsc{Small} (default) small capitals!
				
	\item[nofligatures] provides a typeseting without the ff, fi, fl, ffi and ffl ligatures.
	      
	      The letter \textit{f} has a new design to get a good aspect. 
	      
	      This option has no effect with \textit{oldstyle}
	      or \textit{veryoldstyle} ones.
	      
	      You get for instance, {\fontfamily{jkpf}\selectfont "A final effort"}
	      instead of, "A final effort".
	      
	      And also, {\fontfamily{jkpf}\fontshape{it}\selectfont "A final effort"}
	      instead of, \textit{"A final effort"}.
\end{description}

\subsection{New text commands}

\begin{description}
  \item[\textbackslash textscsl\{\dots\}] and \textbf{\textbackslash scslshape :} 
        provide slanted small caps.
        
        \begin{center}
        \textscsl{Slanted small caps}
        \end{center}
  
  \begin{center}
  \textit{Obviously, }\verb=\textsc{\textsl{...}}=\textit{ has not the same effect!}
  
  \textit{This shape is not usual in \TeX!}
  \end{center}
  \item[\textbackslash otherscshape, \textbackslash textothersc\{\dots\}]
        get the \textit{other} small caps (default or large) roman or sans-serif.
        
        \begin{center}
        For instance, you swap between
        
        \textsc{Small caps text} \quad\textit{and}\quad \textothersc{Small caps text}
        \end{center}
  \item[\textbackslash otherscslshape, \textbackslash textotherscsl\{\dots\}]
        get the \textit{other} slanted small caps (default or large) roman or sans-serif.
        
        \begin{center}
        For instance, you swap between
        
        \textscsl{Small caps text} \quad\textit{and}\quad \textotherscsl{Small caps text}
        \end{center}
  \item[\textbackslash othertailQ]
        provides the other design of the uppercase letter "Q",
        with small or large tail.
        
        \begin{center}
        For instance, you swap between
        
        Question \quad\textit{and}\quad \othertailQ uestion
        \end{center}
  \item[\textbackslash othertailscq, \textbackslash othertailscslq] 
        are the same commands for the lowercase small capitals "\textsc{q}".
        
        \begin{center}
        For instance, you swap between
        
        \textsc{question} \quad\textit{and}\quad \textsc{\othertailscq uestion}
        \end{center}
\end{description}

\begin{center}
\textit{The "other" commands change the \textbf{size} of the small caps}

\textit{and the "othertail" commands change the \textbf{design} of the letters "Q"}
\end{center}

\subsection{Math font options}

\begin{description}
	\item[nomathscript:] Kp-Fonts doesn't install the \verb=\mathscr= command; you need it if you use \verb=\mathrsfs=
				package;
	\item[mathcalasscript:] swaps the \verb=\mathcal= and \verb=\mathscr= fonts;
	\item[classicReIm:] the \verb=\Re= and \verb=\Im= commands produce $\mathfrak{R}$ and $\mathfrak{I}$. In default of, Kp-Fonts provides $\Re$ and $\Im$;
	\item[uprightRoman:] the \textit{Uppercase} romans are upright.
	\item[frenchstyle:] equivalent to both the options \texttt{\textbf{uprightRoman}} 
	
	and \texttt{\textbf{uprightgreeks}}, uppercase romans and lowercase greeks are upright, usual French style when typesetting mathematics; lowercase romans remain slanted;
	\item[upright :] synonymous with the previous option;
	\item[oldstylenumsmath:] provides the oldstyle numbers in default and changes the \verb=\mathrm=,
				\verb=\mathsf= and \verb=\mathtt= fonts; they run as text fonts with \texttt{oldstylenums} option;
	\item[oldstylemath:] provides the oldstyle numbers in default and changes the \verb=\mathrm=,
				\verb=\mathsf= and \verb=\mathtt= fonts; they run as text fonts with \texttt{oldstyle} option;
	\item[veryoldstylemath :] same as \texttt{oldstylemath} except the round "s"
		is replaced with the long "{\fontfamily{jkpvos}\selectfont s}\,";
	\item[narrowiints :] provides narrower multiple integral symbols :
	
				$\narrowiiint$ and $\displaystyle\narrowiiint$\quad instead of\quad
				$\iiint$ and $\displaystyle\iiint$
	\item[partialup :] provides upright design of the \verb=\partial= symbol :
	                   
	                   $\partialup$\quad instead of\quad$\partial$
	\item[widermath :] with wider space between mathematic letters;
	\item[noDcommand :] for compatibility with some other package, kpfont doesn't load the command \verb=\D=.
\end{description}

Note that, when using the \verb+oldstylenumsmath+, \verb+oldstylemath+, 

\verb+veryoldstylemath+, 
\verb+fulloldstylenums+, \verb+fulloldstyle+ 

or \verb+fullveryoldstyle+ options,
in math mode, as the numbers {\fontfamily{jkpvos}\selectfont 3, 4, 5, 7 et 9} have a depth, superscripts are moved up.

\subsection{Greek letters in math mode, options}

\begin{description}
	\item[uprightgreeks:] \textit{lowercase} greeks are upright, $\alphaup\betaup\gammaup$;
	\item[slantedGreeks:] \textit{Uppercase} greeks are slanted, $\Gammasl\Deltasl$. 
\end{description}

\section{Use}

\subsection{Greek letters}

We have described above the two options that alter the default greek letters. 

Otherwise, you can get the other greek letters using commands like 

\verb=\otheralpha= or \verb=\otherGamma=. 

The result depends on the used options.

What's more, for uppercase, you can use \verb=\varGamma= synonymous with the previous.

Finally, the \verb=\alphasl=, \verb=\alphaup=, \verb=\Gammaup= or \verb=\Gammasl= commands always give you the letter you want, whatever the chosen options\dots

\subsection{Standard symbols}

All the standard symbols are present, including all the symbols of the \texttt{amssymb} package, all with regular and bold weight.

For instance: the standard symbols\quad $\leq\quad\bullet\quad\pm$\quad or \textsc{ams} symbols \quad$\twoheadrightarrow\quad\subsetneq\quad\leqslant$

\mathversion{bold}
and in bold:\quad$\leq\quad\bullet\quad\pm$\quad or \quad$\twoheadrightarrow\quad\subsetneq\quad\leqslant$.
\mathversion{normal}

Obviously, you get the usual constructions, both regular and bold: \quad $\mapsto\longmapsto$,\quad
\mathversion{bold}$\mapsto\longmapsto$\mathversion{normal}

\subsection{Extra symbols}

Kp-Fonts provides a lot of other symbols and a lot of negative symbols not displayed here.

%\mathversion{bold}

\begin{center}\begin{tabular}{r>{$}c<{$}|r>{$}c<{$}}

\verb=\varemptyset=&\varemptyset& & \\
\verb=\leadstoext=&\leadstoext&\verb=\leadsto=&\leadsto\\

\end{tabular}\end{center}

You can combine these last two symbols:

\end{tabular}\end{center}

\verb=\lbag=, \verb=\rbag=, \verb=\llbracket= and \verb=\rrbracket= are vertically extensive.

\subsection{Variant integrate symbols}

When we write a primitive, often the result is not very attractive because the function is too far from the integrate symbol.

As you can see here:

\[\int f(t)\,\mathrm{d}t\]

Kp-Fonts provides variant commands to avoid this. The first is the \verb=\varint= command and you get:

\[\varint f(t)\,\mathrm{d}t\]

It is up to you to choose whichever you prefer!

Obviously, this command is not convenient for computing an integral\dots

You can also use \verb=\D{...}=, the integrate symbol "d" command with best spacing:
	
	\qquad\verb=\displaystyle\varint f(t)\D{t}=\qquad gives\qquad
	$\displaystyle\varint f(t)\D{t}$
	
\bigskip
	
	With the \textit{frenchstyle} option, you get an upright "d", like above.
	
\bigskip

Others variant commands are:

\verb=\variint=, \verb=\variiint=, \verb=\variiiint= et \verb=\varidotsint=.

\subsection{New extensive symbols}

First, the \verb=\widehat= et \verb=\widetilde= commands have been extended:
\[\widetilde{tilde}\qquad\widehat{chapeau}\]

You get also th extensive \verb=\widearc=, \verb=\widearcarrow= (ou \verb=\wideOarc=), 

\verb=\wideparen=
and \verb=\widering= :
\[\widearc{arc}\qquad\widearcarrow{arrow}\qquad\wideparen{paren}\qquad\widering{RING}\]

This last command makes an error with the option \verb=noamsmath=

Finally, some new symbols:

\renewcommand{\arraystretch}{1.8}

\begin{center}\begin{tabular}{r>{$}c<{$}>{$\displaystyle}c<{$}|r>{$}c<{$}>{$\displaystyle}c<{$}}

\verb=\bignplus=&\bignplus&\bignplus&\verb=\bigsqcupplus=&\bigsqcupplus&\bigsqcupplus\\
\verb=\bigsqcapplus=&\bigsqcapplus&\bigsqcapplus&\verb=\bigsqcap=&\bigsqcap&\bigsqcap\\
\verb=\varprod=&\varprod&\varprod&\\

\end{tabular}\end{center}


\subsection{More integrate symbols}

There are many unusual integrate symbols :

\renewcommand{\arraystretch}{2}

\begin{center}
\begin{tabular}{r>{$}c<{$}c|r>{$}c<{$}c} 
\verb+\oiint+ &\oiint& $\displaystyle\oiint$ &

\section{Installation}

\begin{itemize}
	\item 
	
With MikTeX, install the package as described here:

	\begin{verbatim}
	http://docs.miktex.org/manual/pkgmgt.html#id562117
	\end{verbatim}
	
	\item
	
With other distribution, or to install manualy with MikTeX, follow these instructions:

\begin{enumerate}
	\item 
The tree provides a standard \textsc{tds}. You have to copy all the files in one of your local \texttt{texmf} trees first and then update your data base files.
	\item
Now, you have to deal with the \texttt{.map} file.
\begin{itemize}
	\item 
If you have a \texttt{web2c} distribution, just run \texttt{updmap}:

	\begin{verbatim}
	updmap --enable Map=kpfonts.map
	\end{verbatim}
	
and/or, this time as \textit{root}:

	\begin{verbatim}
	updmap-sys --enable Map=kpfonts.map
	\end{verbatim}
	
	\item
With MikTeX, follow the instructions of the manual:

	\begin{verbatim}
	http://docs.miktex.org/manual/advanced.html#psfonts
	\end{verbatim}
	
\end{itemize}
	
\end{enumerate}
	
\end{itemize}

\section{Some extra points}

\subsection{The \textsc{Johannes Kepler}-project text families}

If you want, or if you have to use the low-level commands, the names of the families are:

\begin{center}\begin{tabular}{|l|l|}\hline
\textbf{roman}& jkp[l,x][k][f][osn,os,vos]\\\hline
\textbf{sans serif}& jkpss[k][f][osn,os,vos]\\\hline
\textbf{teletype}& jkptt[osn,os,vos]\\\hline
\end{tabular}\end{center}

with the relative options:

\begin{center}\begin{tabular}{|l|l|}\hline
\textbf{l, x}& light, rmx\\\hline
\textbf{k}& largesmallcaps\\\hline
\textbf{f}&nofligatures\\\hline
\textbf{osn, os, vos}& oldstylenums, oldstyle, veryoldstyle\\\hline
\end{tabular}\end{center}

Obviously, you can't have \textbf{f} and \textbf{os} or \textbf{vos}.

Note that all the families support \textsc{ot}\oldstylenums{1}, \textsc{t}\oldstylenums{1} and \textsc{ts}\oldstylenums{1} encodings.


\subsection{Metrics and compatibility}

\begin{itemize}
	\item The \textit{light} option does not change any metric;
	\item The \textit{oldstylenums} or \textit{oldstyle} options do not change any horizontal metric;
	\item The \textit{veryoldstyle} family options change the metrics of the lowercase 's'
				and the height of the superscripts in math mode;
	\item There is a full compatibility of the options, except if it is a nonsense,
				like both the \textit{nomath} and \textit{frenchstyle} options;
	\item In case of conflict between \textit{oldstylenums}, \textit{oldstyle} and \textit{veryoldstyle} family options,
				the lighter options are ignored.
\end{itemize}

\subsection{Displaying and printing}

Often, some display and printing problems exist\dots

The main reason is an automatic hinting. I'm not a professional typograph and I can't do better;
besides, there are some printing problems with old releases of \textit{Acroread}\textregistered{} using \textit{Windows}\textregistered.

Note that the printing is better using \textit{Ghostscript-Ghostview}\textregistered\dots

With the \textit{light} option, the print is better than display!

\subsection{Abstract}

You get almost all the features of \textit{kpfonts} in one page with the file

\begin{center}\textit{kpfonts-abstract.pdf}\end{center}

\subsection{Searching a word}

With the \texttt{veryoldstyle} options, the brownsers don't find the rare ligatures \textbf{si, sl, st} and the \texttt{sacute, scaron} and \texttt{scedilla}. 

\begin{center}
\textit{Don't use this option if you want to search these words!}
\end{center}

\subsection{My favorite options}

\begin{itemize}
	\item For text-only document, I use the \textit{light} and \textit{oldstyle} options;
	\item and for text and math document, I use the \textit{light, frenchstyle},
				
				\textit{narrowiints} and \textit{partialup} options, but I'm french!
\end{itemize}

\subsection{\textsc{Johannes Kepler 1571-1630}}

    \textsc{Kepler} was forced, due to the counter Reformation and because he was a Lutheran, to move to Prague to work with the renowned Danish astronomer, \textsc{Tycho Brahe}. Using the data that \textsc{Tycho} had collected, \textsc{Kepler} discovered the first two laws of planetary motion (1609). And what is just as important about this work is that it is the first published account wherein a scientist documents shows how he has coped with the multitude of imperfect data to forge a theory of surpassing accuracy" (\textsc{O. Gingerich} in foreword to \textsc{Johannes Kepler} New Astronomy translated by \textsc{W. Donahue}, Cambridge Univ Press, 1992), in other words a fundamental law of nature. Today we call this the scientific method.

\subsection{Remark}

Note that \textit{Kepler}\textregistered{} is a registered font name supplied by \textit{Adobe}\texttrademark. 

The Kp-Fonts have nothing to do with those.
