\section{Library \mylib{skins}}\label{sec:skins}
The library is loaded by a package option or inside the preamble by:
\begin{dispListing}
\tcbuselibrary{skins}
\end{dispListing}
This also loads the package |tikz| \cite{tantau:2013a}. Typically but not necessarily,
the following skins use |tikz| instead of |pgf|.
\subsection{Technical Overview and Core Package Option Keys}\label{sec:skincorekeys}
From a technical point of view, a \emph{skin} is a style definition for the
appearance of a |tcolorbox|. The core package provides some additional
option keys for skins but only a single skin called \refSkin{standard}.
The \mylib{skins} library adds several more skins. To change a skin, only one
option from the core package has to be set.
\begin{docTcbKey}{skin}{=\meta{name}}{style, no default, initially \texttt{standard}}
Sets the current skin to \meta{name}. This is a style definition which sets all the following
keys, i.\,e.\ for many use cases there is nothing more to do.
\begin{dispExample}
\tcbset{colback=Salmon!50!white,colframe=FireBrick!75!black,
width=(\linewidth-8mm)/2,before=,after=\hfill,equal height group=ske}
\begin{tcolorbox}[adjusted title=My title]
This is my content.
\end{tcolorbox}
\begin{tcolorbox}[skin=beamer,beamer,adjusted title=My title]
This is my content.
\end{tcolorbox}
\end{dispExample}
\end{docTcbKey}
\begin{marker}
On first read, you may skip the rest of this subsection and proceed to
Subsection \ref{subsec:addstyleoptions} on page \pageref{subsec:addstyleoptions}.
All following keys in this subsection are automatically set by the selected skin
and you may never have to temper with them.
Nevertheless, they can be used after a skin was selected to modify
this skin.
\end{marker}
\begin{docTcbKey}{skin first}{=\meta{name}}{style, no default, initially \texttt{standard}}
If the box is set to be \refKey{/tcb/breakable} and \emph{is} broken actually,
then the skin for the \emph{first} part of the break sequence
is set to \meta{name}, see Subsection \ref{subsec:breaksequence} on page \pageref{subsec:breaksequence}.
Typically, this key is set by a \refKey{/tcb/skin}.
\end{docTcbKey}
\begin{docTcbKey}{skin middle}{=\meta{name}}{style, no default, initially \texttt{standard}}
If the box is set to be \refKey{/tcb/breakable} and \emph{is} broken actually,
then the skin for the \emph{middle} parts (if any) of the break sequence
is set to \meta{name}, see Subsection \ref{subsec:breaksequence} on page \pageref{subsec:breaksequence}.
Typically, this key is set by a \refKey{/tcb/skin}.
\end{docTcbKey}
\begin{docTcbKey}{skin last}{=\meta{name}}{style, no default, initially \texttt{standard}}
If the box is set to be \refKey{/tcb/breakable} and \emph{is} broken actually,
then the skin for the \emph{last} part of the break sequence
is set to \meta{name}, see Subsection \ref{subsec:breaksequence} on page \pageref{subsec:breaksequence}.
Typically, this key is set by a \refKey{/tcb/skin}.
\end{docTcbKey}
\begin{docTcbKey}{graphical environment}{=\meta{name}}{no default, initially \texttt{pgfpicture}}
Sets the graphical environment for the |tcolorbox| to \meta{name}.
Feasible values are |pgfpicture| and |tikzpicture| or environments which
inherit from one of these two. This key is set by a \refKey{/tcb/skin} and
may seldom be used directly.
\end{docTcbKey}
The skin of a |tcolorbox| is drawn by up to four \emph{engines}.
Afterwards, the text content is drawn which is not part of a skin.
The four steps are:
\begin{enumerate}
\item The \emph{frame} of the box.
\item The \emph{interior} of the box. The interior of a box with title is
drawn differently from a box without title.
\item The \emph{segmentation} (line) of the box, if there is a lower part.
\item The \emph{title area} of the box, if there is a title.
\end{enumerate}
Every engine for the up to four steps can be set to one of the following types:
\begin{enumerate}
\item\docValue{standard}: the original code from the core package.
\item\docValue{path}: a |tikz| path which can be controlled by options.
\item\docValue{pathfirst}: a |tikz| path which can be controlled by options.
\item\docValue{pathmiddle}: a |tikz| path which can be controlled by options.
\item\docValue{pathlast}: a |tikz| path which can be controlled by options.
\item\docValue{freelance}: arbitrary user code.
\item\docValue{spartan}: a quite spartan code.
\end{enumerate}
%\clearpage
\begin{docTcbKey}{frame engine}{=\meta{name}}{no default, initially \texttt{standard}}
Sets the \emph{frame} drawing engine for a box to \meta{name}.
Typically, this key is set by a \refKey{/tcb/skin}.
Feasible values for \meta{name} are:
\begin{itemize}
\item\docValue{standard}: the original code from the core package,
\item\docValue{path}: a |tikz| path which is controlled by \refKey{/tcb/frame style},
\item\docValue{pathjigsaw}: a |tikz| path which is controlled by \refKey{/tcb/frame style},
\item\docValue{pathfirst}: a |tikz| path which is controlled by \refKey{/tcb/frame style},
\item\docValue{pathfirstjigsaw}: a |tikz| path which is controlled by \refKey{/tcb/frame style},
\item\docValue{pathmiddle}: a |tikz| path which is controlled by \refKey{/tcb/frame style},
\item\docValue{pathmiddlejigsaw}: a |tikz| path which is controlled by \refKey{/tcb/frame style},
\item\docValue{pathlast}: a |tikz| path which is controlled by \refKey{/tcb/frame style},
\item\docValue{pathlastjigsaw}: a |tikz| path which is controlled by \refKey{/tcb/frame style},
\item\docValue{freelance}: arbitrary user code which is given by \refKey{/tcb/frame code}.
\item\docValue{spartan}: a quite spartan code.
\end{itemize}
\end{docTcbKey}
\begin{docTcbKey}{interior titled engine}{=\meta{name}}{no default, initially \texttt{standard}}
Sets the \emph{interior} drawing engine for a titled box to \meta{name}.
Typically, this key is set by a \refKey{/tcb/skin}.
Feasible values for \meta{name} are:
\begin{itemize}
\item\docValue{standard}: the original code from the core package,
\item\docValue{path}: a |tikz| path which is controlled by \refKey{/tcb/interior style},
\item\docValue{pathfirst}: a |tikz| path which is controlled by \refKey{/tcb/interior style},
\item\docValue{pathmiddle}: a |tikz| path which is controlled by \refKey{/tcb/interior style},
\item\docValue{pathlast}: a |tikz| path which is controlled by \refKey{/tcb/interior style},
\item\docValue{freelance}: arbitrary user code which is given by \refKey{/tcb/interior titled code}.
\item\docValue{spartan}: a quite spartan code.
\end{itemize}
\end{docTcbKey}
\clearpage
\begin{docTcbKey}{interior engine}{=\meta{name}}{no default, initially \texttt{standard}}
Sets the \emph{interior} drawing engine for an untitled box to \meta{name}.
Typically, this key is set by a \refKey{/tcb/skin}.
Feasible values for \meta{name} are:

\subsection{Watermark Option Keys}\label{subsec:watermarks}
The following watermark options are applicable for all skins which
use |tikzpicture| as \refKey{/tcb/graphical environment}.
Therefore, the skin \refSkin{standard} does not support these watermarks,
but all other skins, e.\,g.\ \refSkin{enhanced}.
\begin{marker}
The watermark options rely on the more general overlay options described in
Section \ref{subsec:overlays} from page \pageref{subsec:overlays}.
Therefore, \emph{watermarks} and \emph{overlays} cannot be used mixed.
But a mixture is possible with the \mylib{hooks} library, see Section \ref{sec:hooks}.
\end{marker}
\begin{docTcbKey}{watermark text}{=\meta{text}}{no default, initially unset}

frame and interior are drawn and \emph{before} the text content is drawn.
It is zoomed or stretched according the values of
\refKey{/tcb/watermark zoom} or \refKey{/tcb/watermark stretch}.
\begin{dispExample}
\tcbset{colback=red!5!white,colframe=red!75!black,fonttitle=\bfseries}
\begin{tcolorbox}[enhanced,title=My title,watermark text=My Watermark]
\lipsum[1]

This option writes some \meta{text} in the center of the interior region of a |tcolorbox|
as described for \refKey{/tcb/watermark text}.
But this is done only for boxes named \meta{part} of a break sequence, see
\refKey{/tcb/breakable}.\\
Feasible values for \meta{part} are:
\begin{itemize}
\item |broken|: all broken box parts,
\item |unbroken|: unbroken boxes only,
\item |first|: first parts of a break sequence,
\item |middle|: middle parts of a break sequence,
\item |last|: last parts of a break sequence,
\item |unbroken and first|: unbroken boxes and first parts of a break sequence,
\item |middle and last|: middle and last parts of a break sequence.

\clearpage
\begin{docTcbKey}{watermark graphics}{=\meta{file name}}{no default, initially unset}
Draws an external picture referenced by \meta{file name}
in the center of the interior region of a |tcolorbox|.
The picture is drawn \emph{after} the
frame and interior are drawn and \emph{before} the text content is drawn.
It is zoomed or stretched according the values of
\refKey{/tcb/watermark zoom} or \refKey{/tcb/watermark stretch}.
\begin{dispExample}

This option draws the given |tikz| \meta{graphical code} in the center of the interior region of a |tcolorbox|
as described for \refKey{/tcb/watermark tikz}.
But this is done only for boxes named \meta{part} of a break sequence, see
\refKey{/tcb/breakable}.\\
Feasible values for \meta{part} are:
\begin{itemize}
\item |broken|: all broken box parts,
\item |unbroken|: unbroken boxes only,
\item |first|: first parts of a break sequence,

\enlargethispage{5mm}
\begin{docTcbKey}{watermark zoom}{=\meta{fraction}}{no default, initially |0.75|}
Sets the zoom value for a watermark. The zoom respects the aspect ratio.
The value $1.0$ means to fill the whole box until the watermark touches the frame.
\begin{dispExample}
\tcbset{enhanced,colback=red!5!white,colframe=red!75!black,fonttitle=\bfseries,

\end{docTcbKey}
\clearpage
\begin{docTcbKey}{watermark overzoom}{=\meta{fraction}}{no default, initially unset}
Sets the overzoom value for a watermark. The overzoom respects the aspect ratio.
The value $1.0$ means to fill the whole box until the watermark touches
all four sides of the frame.
\begin{dispExample}
\tcbset{enhanced,colback=white,colframe=blue!50!black,fonttitle=\bfseries,

\end{docTcbKey}
\begin{marker}
If a \refKey{/tcb/watermark overzoom} value of |1.0| is used in connection
with invisible top and bottom rules which still have a thickness greater than |0pt|,
the space of these invisible rules may not be covered by the watermark.
For example, this situation may occur during the breaking of \refKey{/tcb/enhanced} boxes.
To avoid this optical glitch, just set \refKey{/tcb/pad at break} to any desired value.
\end{marker}
\clearpage
\begin{docTcbKey}{watermark stretch}{=\meta{fraction}}{no default, initially unset}
Sets the stretch value for a watermark. The stretch value is applied to width

\subsection{Border Line Option Keys}\label{subsec:borderline}
The following border line options are applicable for most skins which
use |tikzpicture| as \refKey{/tcb/graphical environment}.
Therefore, the skin \refSkin{standard} does not support these border lines,
but most other skins, e.\,g.\ \refSkin{enhanced}.
The border lines are independent from the normal |tcolorbox| rules.
They may be used with or without the \refKey{/tcb/segmentation engine}.
The border lines are stackable, i.\,e.\ several different border lines can be
used on the same |tcolorbox|. They are drawn \emph{after} the box frame and box
interior and \emph{before} overlays or watermarks.
\begin{marker}
Technically, the normal |tcolorbox| rules result from a TikZ \emph{filling}
process. The border lines are created by a TikZ \emph{drawing} process.
This can be used to apply different effects.
\end{marker}
\begin{docTcbKey}{borderline}{=\marg{width}\marg{offset}\marg{options}}{no default, initially unset}
Adds a new border line to the stack of border lines.
This border line is drawn with the given \meta{width} and gets a
\meta{offset} computed from the frame outline. A positive \meta{offset} value
moves the borderline inside the |tcolorbox| and a negative \meta{offset} value
moves it outside without changing the bounding box.\\
The border line is drawn along a TikZ path with the given TikZ \meta{options}.
Note that the TikZ |line width| option should not be used here.\\
The border lines adapt to the rounded corners of the |tcolorbox|. An inside border
line will switch to sharp corners if necessary, an outside border line will
always be rounded if not set to |sharp corners|.
\begin{dispExample}
\begin{tcolorbox}[enhanced,title=Rounded corners,fonttitle=\bfseries,boxsep=5pt,
arc=8pt,
borderline={0.5pt}{0pt}{red},
borderline={0.5pt}{5pt}{blue,dotted},

Removes all border lines if set before.
\end{docTcbKey}
\begin{docTcbKey}{show bounding box}{\colOpt{=\meta{color}}}{default |red|, initially unset}
Technically, this option is no borderline option but an overlay option, see
\Vref{subsec:overlays}. It is documented here, because it needs a
|tikzpicture| environment and it displays the bounding box borderline of
a |tcolorbox|. Its intended use is debugging and fine tuning.
The optional \meta{color} is the base color for the bounding box
borderline.
\begin{dispExample}
\tcbset{enhanced,nobeforeafter,width=4cm,fonttitle=\bfseries}
\begin{tcolorbox}[show bounding box,title=Normal]

\subsection{Shadow Option Keys}\label{subsec:shadows}
The following shadow options are applicable for most skins which
use |tikzpicture| as \refKey{/tcb/graphical environment}.
Therefore, the skin \refSkin{standard} does not support these shadows,
but most other skins, e.\,g.\ \refSkin{enhanced}.
The shadows are stackable, i.\,e.\ several different shadows can be
used on the same |tcolorbox|. They are drawn \emph{before} the box frame is drawn.
\begin{docTcbKey}{no shadow}{}{no default}
Removes all shadows if set before.
\end{docTcbKey}
\begin{docTcbKey}{shadow}{=\marg{xshift}\marg{yshift}\marg{offset}\marg{options}}{no default}
Adds a new shadow to the stack of shadows.
This shadow is follows the outline of the |tcolorbox| but is shifted by
\meta{xshift} and \meta{yshift}. The \meta{offset} value is a distance value
from the frame outline. A positive \meta{offset} value shrinks the shadow
and a negative \meta{offset} value enlarges the shadow.
The shadow is filled along a TikZ path with the given TikZ \meta{options}.\\
The shadows adapt to the rounded corners of the |tcolorbox|. An shrinked shadow
will switch to sharp corners if necessary, an enlarged shadow may become
more rounded depending on several factors.
\begin{marker}
Shadows are not considered for the bounding box computation by default.
Large shadows may be overlaped by the following content. But, the
bounding box can be adapted if necessary.

\end{docTcbKey}
\clearpage
\begin{docTcbKey}{fuzzy shadow}{=\marg{xshift}\marg{yshift}\marg{offset}\marg{step}\marg{options}}{no default}
Adds a new fuzzy shadow to the stack of shadows. Actually, this option
adds seversal shadows which appear like a shadow with a fuzzy border.
This fuzzy shadow is follows the outline of the |tcolorbox| but is shifted by
\meta{xshift} and \meta{yshift}. The \meta{offset} value is a distance value
from the frame outline. A positive \meta{offset} value shrinks the shadow
and a negative \meta{offset} value enlarges the shadow.
The \marg{step} value describes a shrink
offset used for the combination of the partial shadows.
The shadow is filled along a TikZ path with the given TikZ \meta{options} but
any |opacity| value will be ignored.
\begin{dispExample*}{sbs,lefthand ratio=0.6}

\subsection{TikZ Picture Option Keys}\label{subsec:tikzpicture}
The following general options are applicable for skins which
use |tikzpicture| as \refKey{/tcb/graphical environment}.
Therefore, the skin \refSkin{standard} does not support these options,
but most other skins, e.\,g.\ \refSkin{enhanced}.
\begin{docTcbKey}{tikz}{=\meta{tikz option list}}{no default, initially empty}
Adds the given \meta{tikz option list} to the main |tikzpicture| environment
used to draw the color box, see \cite{tantau:2013a}. If this option is
applied a second time, the new \meta{tikz option list} is appended to the
current option list.
\begin{dispExample*}{sbs,lefthand ratio=0.66,
segmentation style={pattern=crosshatch dots light steel blue}}
\tcbset{enhanced,colback=red!5!white,
colframe=red!75!black,fonttitle=\bfseries}

Removes all options given by \refKey{/tcb/tikz}.
\end{docTcbKey}
\begin{docTcbKey}{at begin tikz}{=\meta{tikz code}}{no default, initially empty}
The given \meta{tikz code} is executed at the beginning of the |tikzpicture| environment
after the TikZ option |execute at begin picture| was applied.
If this option is applied a second time, the new \meta{tikz code} is appended to the current code.
\end{docTcbKey}
\begin{docTcbKey}{at begin tikz reset}{}{initially set}
Removes all code given by \refKey{/tcb/at begin tikz}.
\end{docTcbKey}
\begin{docTcbKey}{at end tikz}{=\meta{tikz code}}{no default, initially empty}
The given \meta{tikz code} is executed at the ending of the |tikzpicture| environment
before the TikZ option |execute at end picture| was applied.
If this option is applied a second time, the new \meta{tikz code} is appended to the current code.
\end{docTcbKey}
\begin{docTcbKey}{at end tikz reset}{}{initially set}
Removes all code given by \refKey{/tcb/at end tikz}.
\end{docTcbKey}
\clearpage
\begin{docTcbKey}{rotate}{=\meta{angle}}{no default, initially unset}
Rotates the |tcolorbox| by the given \meta{angle}. Note that this is
a TikZ coordinate transformation i.e. not all graphical elements like shadings
will really be rotated.
\begin{dispExample*}{sbs,lefthand ratio=0.66}

a TikZ coordinate transformation i.e. not all graphical elements like line widths
will really be scaled.
\begin{dispExample*}{sbs,lefthand ratio=0.66}

\subsection{Jigsaw Skin Variants}\label{subsec:skinjigsaw}
As described in \Vref{sec:skincorekeys}, a |tcolorbox| is drawn by up to
four \emph{engines}. Typically, the \emph{frame} engine fills the complete box area
with color and the other engines fill certain areas with other colors.
Finally, only the area which you see as \emph{frame} of the box will display
the frame color. For most applications, this is a good approach.
For certain boxes, a more delicate procedure is needed. E.g., if the box should
be translucent, an already painted area cannot be made unpainted. Therefore,
more elaborate frame engines saw holes into the frame where the interior area and
optionally the title area will be painted.
The resulting skins are called \emph{jigsaw} skins. For \refSkin{standard}
and \refSkin{enhanced}, there are variants called \refSkin{standard jigsaw}
and \refSkin{enhanced jigsaw}.
\begin{dispExample}
\newcommand{\ballexample}{\begin{tikzpicture}
\path[use as bounding box] (0,0.8) rectangle +(0.1,0.1);
\shadedraw [shading=ball] (0,0) circle (1cm);
\shadedraw [ball color=red] (3,-2.2) circle (1cm);
\end{tikzpicture}}

\subsection{Draft Mode}\label{subsec:draftmode}
To reduce the compiliation time while drafting a document, the \emph{draft mode}
can be applied. Basically, it changes all skins to \refSkin{spartan} and
sets the \refKey{/tcb/fit algorithm} to |squeeze|. Especially,
when fuzzy shadows are used, the speedup will be considerable high.
\begin{marker}
It is strongly recommended that the draft mode is \emph{not} used for the final document.
Use \refSkin{spartan} directly, if you want to stay with it. The draft mode
implementation may change in future.
\end{marker}
\begin{marker}
Normally, switching to the draft mode should not alter the geometry of
your document. Since overlays are deactivated, any code placed there
(e.g. counter changes) is not executed anymore! Also, \refKey{/tcb/remember as}
will not have any effect. You may exclude critical code with
\refCom{tcbinterruptdraftmode} / \refCom{tcbcontinuedraftmode}
from converting to draft mode.
\end{marker}
\begin{docCommand}{tcbstartdraftmode}{}
Any following |tcolorbox| code is put into \emph{draft mode}. All skin
settings are overruled with \refSkin{spartan}. Overlays, watermarks,
shadows, borderlines, and rounded corners are deactivated for all |tcolorbox|
layers.
\end{docCommand}
\begin{docCommand}{tcbstopdraftmode}{}
The \emph{draft mode} is deactivated for the following code.
\end{docCommand}
\begin{docCommand}{tcbinterruptdraftmode}{}
If the compilation is in \emph{draft mode}, the \emph{draft mode} is deactivated
until a following \refCom{tcbcontinuedraftmode} is detected.\par
If the compilation is not in \emph{draft mode}, no happens and a following
\refCom{tcbcontinuedraftmode} will not start the \emph{draft mode}.
\begin{marker}
The pair |\tcbinterruptdraftmode| and |\tcbcontinuedraftmode| cannot
be used nested.
\end{marker}
\end{docCommand}
\begin{docCommand}{tcbcontinuedraftmode}{}
Continues the \emph{draft mode} which was suspended by a preceding
\refCom{tcbinterruptdraftmode}. Nothing happens, if there was no draft
mode before \refCom{tcbinterruptdraftmode}.
\begin{marker}
Code, which is place between \refCom{tcbinterruptdraftmode} and
\refCom{tcbcontinuedraftmode} is shielded from \emph{draft mode}.
\end{marker}
\end{docCommand}
\enlargethispage*{2cm}
\begin{docTcbKey}{draftmode}{\colOpt{=true\textbar false}}{default |true|, initially |false|}
If set to |true|, the \emph{draft mode} is started.
If set to |false|, the \emph{draft mode} is stopped.

This skin family is intended for the experienced user who looks for special
customizations of a |tcolorbox|. It gives full freedom for the appearance,
but it requires some |tikz| coding. For small adaptions, you may want to use
overlays instead, see \Vref{subsec:overlays}.

This skin is useful for boxes which should differ much from the normal
appearance. Note that this difference has to be programmed by the user.

\subsection{Skin Family 'bicolor'}
\begin{docSkin}{bicolor}
This skin is quite similar to the \refSkin{standard} and \refSkin{enhanced} skin.
But instead of a segmentation line, the optional lower part of the box is filled with a
different color or drawn with a different style.

\refKey{/tcb/segmentation engine}: \> |freelance|\\
\refKey{/tcb/title engine}: \> |path|
\end{tabbing}
\end{tcolorbox}
\begin{itemize}
\item The most basic usage of this skin is to set the background color of
the lower part by \refKey{/tcb/colbacklower} and all other options like for
the \refSkin{standard} skin.
\begin{dispExample}
\begin{tcolorbox}[skin=bicolor,title=The title,

The upper part.
\tcblower
The lower part.

\end{dispExample}
\item The more advanced usage of this skin is to apply the \refKey{/tcb/frame style}

the \refSkin{enhanced} skin. Also, the \refKey{/tcb/segmentation style} can be
used, but it is applied to the whole lower part.

\subsection{Skin Family 'beamer'}
\begin{docSkin}{beamer}
This skin resembles boxes known from the |beamer| class and therefore is
called 'beamer'. It uses the normal colors from the core package but shades
them a little bit. To use this skin, the |tikz| library |shadings|
has to be included in the preamble by:
\begin{dispListing}
\usetikzlibrary{shadings}
\end{dispListing}
The appearance of the skin can be controlled by \refKey{/tcb/frame style}
and \refKey{/tcb/interior style}, if needed. Here, the \emph{segmentation}
cannot be controlled by a style.
