This means that printing applications requiring +% CMYK shadings can not easily be produced. It also can lead to unexpected +% colour mismatches in documents when attempting to define a shading from +% colours defined in CMYK. This can occur when the |natural| colour model of the +% \pkg{xcolor} package is in use and colours like cyan and magenta are defined +% as CMYK. An attempt to produce a shading using these colours will be +% silently converted to RGB, but RGB cyan and RGB magenta look significantly +% different from CMYK cyan and magenta. This is a significant cause of +% confusion for end users. +% +% The following example illustrates this problem and the corresponding solution +% provided by the \pkg{pgf-cmykshadings} package. +% +% \begin{quote} +% \iffalse +%<*example> +% \fi +\begin{lstlisting} +\begin{tikzpicture} + \fill[cyan] (0,0) rectangle (1,1); + \shade[left color=cyan, right color=magenta] + (1.25,0) rectangle (3.75,1); + \fill[magenta] (4,0) rectangle (5,1); +\end{tikzpicture} +\end{lstlisting} +% \iffalse +% +% \fi +% +% \begin{minipage}{0.45\linewidth} +% \pkg{pgf} behaviour:\medskip +% +% \pgfcmykshadingdefaultfalse +% \begin{tikzpicture} +% \fill[cyan] (0,0) rectangle (1,1); +% \shade[left color=cyan, right color=magenta] +% (1.25,0) rectangle (3.75,1); +% \fill[magenta] (4,0) rectangle (5,1); +% \end{tikzpicture} +% \end{minipage}\hfill +% \begin{minipage}{0.45\linewidth} +% \pkg{pgf-cmykshadings} behaviour:\medskip +% +% \pgfcmykshadingdefaulttrue +% \begin{tikzpicture} +% \fill[cyan] (0,0) rectangle (1,1); +% \shade[left color=cyan, right color=magenta] +% (1.25,0) rectangle (3.75,1); +% \fill[magenta] (4,0) rectangle (5,1); +% \end{tikzpicture} +% \end{minipage} +% \end{quote} +% +% \section{Acknowledgements} +% +% Substantial parts of the code for the \pkg{pgf-cmykshadings} package are +% taken from the \pkg{pgf} package files |pgfcoreshade.code.tex|, +% |pgfsys-pdftex.def|, |pgfsys-dvipdfmx.def|, and |pgfsys-luatex.def| copyright +% © 2006 Till Tantau and then slightly modified to support CMYK and grayscale +% shadings. +% +% \section{Bug Reports and Feature Requests} +% +% Bug reports and feature requests can be made at the \pkg{pgf-cmykshadings} +% package GitHub respoitory. See +% \url{https://github.com/dcpurton/pgf-cmykshadings}. +% +% \section{Documentation} +% +% \subsection{Basic Usage} +% +% All that is required to use CMYK shadings instead of RGB shadings is to +% include the package in your document preamble: +% \begin{quote} +% \iffalse +%<*example> +% \fi +\begin{lstlisting} +\usepackage{pgf-cmykshadings} +\end{lstlisting} +% \iffalse +% +% \fi +% \end{quote} +% However, there are some caveats in using the package, which are outlined +% below. +% +% \subsubsection{Package options} +% +% \pkg{pgd-cmykshadings} supports the following package options: +% +% \begin{description} +% \item[\mdseries |cmyk|] (default) to use CMYK shadings when the \pkg{xcolor} +% package |natural| colour model is in use. +% \item[\mdseries |rgb|] to use the RGB shadings when the \pkg{xcolor} package +% |natural| colour model is in use. +% \end{description} +% +% \subsubsection{Load order} +% +% \pkg{pgf-cmykshadings} should be loaded \emph{before} any shadings are defined +% otherwise these will be defined as RGB. This means you should load +% \pkg{pgf-cmykshadings} before (for example) \pkg{tikz} and \pkg{beamer}. +% +% If you want to pass custom options to \pkg{xcolor} (e.g., a colour model or +% set of named colours), you should load \pkg{pgf-cmykshadings} \emph{after} +% \pkg{xcolor} or use \cs{PassOptionsToPackage} \emph{before} loading +% \pkg{pgf-cmykshadings}. +% +% \subsubsection{Colour models} +% +% \pkg{pgf-cmykshadings} attempts to produce shadings consistent with the +% currently selected \pkg{xcolor} package colour model. The |rgb|, |cmyk|, and +% |gray| colour models from the \pkg{xcolor} package are supported. +% +% \textbf{Note:} The colour model chosen for a shading is based on the +% \pkg{xcolor} colour model \emph{at the time the shading is created}. This is +% either when \cs{pgfdeclare*shading} is called with no optional argument or +% when \cs{pgfuseshading} is called if \cs{pgfdeclare*shading} was called with +% an optional argument. +% +% If the \pkg{xcolor} package |natural| colour model is in use then the shading +% colour model will be CMYK by default (equivalent to passing the |cmyk| option +% to the \pkg{pgf-cmykshadings} package). RGB shadings can be output by default +% instead by passing the |rgb| option to the \pkg{pgf-cmykshadings} package. +% +% In practice this means that if you are using the |natural| colour model of the +% \pkg{xcolor} package you can still get mismatched colours if you, for example, +% create a shading from green (which is defined as RGB) to magenta (which is +% defined as CMYK). The shading has to pick one colour model and will look +% different to one of the solid colours. +% +% For this reason it is recommended to always load the \pkg{xcolor} package +% before the \pkg{pgf-cmykshadings} package with either the |rgb|, |cmyk|, or +% |gray| options to avoid colour surprises. +% +% \begin{quote} +% \iffalse +%<*example> +% \fi +\begin{lstlisting} +\begin{tikzpicture} + \fill[green] (0,0) rectangle (1,1); + \shade[left color=green, right color=magenta] + (1.25,0) rectangle (3.75,1); + \fill[magenta] (4,0) rectangle (5,1); +\end{tikzpicture} +\end{lstlisting} +% \iffalse +% +% \fi +% +% \begin{minipage}{0.45\linewidth} +% \pkg{xcolor} |natural| colour model:\medskip +% +% \begin{tikzpicture} +% \fill[green] (0,0) rectangle (1,1); +% \shade[left color=green, right color=magenta] +% (1.25,0) rectangle (3.75,1); +% \fill[magenta] (4,0) rectangle (5,1); +% \end{tikzpicture} +% \end{minipage}\hfill +% \begin{minipage}{0.45\linewidth} +% \pkg{xcolor} |cmyk| colour model:\medskip +% +% \selectcolormodel{cmyk} +% \begin{tikzpicture} +% \fill[green] (0,0) rectangle (1,1); +% \shade[left color=green, right color=magenta] +% (1.25,0) rectangle (3.75,1); +% \fill[magenta] (4,0) rectangle (5,1); +% \end{tikzpicture} +% \end{minipage}\medskip +% +% \begin{minipage}{0.45\linewidth} +% \pkg{xcolor} |rgb| colour model:\medskip +% +% \selectcolormodel{rgb} +% \begin{tikzpicture} +% \fill[green] (0,0) rectangle (1,1); +% \shade[left color=green, right color=magenta] +% (1.25,0) rectangle (3.75,1); +% \fill[magenta] (4,0) rectangle (5,1); +% \end{tikzpicture} +% \end{minipage}\hfill +% \begin{minipage}{0.45\linewidth} +% \pkg{xcolor} |gray| colour model:\medskip +% +% \selectcolormodel{gray} +% \begin{tikzpicture} +% \fill[green] (0,0) rectangle (1,1); +% \shade[left color=green, right color=magenta] +% (1.25,0) rectangle (3.75,1); +% \fill[magenta] (4,0) rectangle (5,1); +% \end{tikzpicture} +% \end{minipage} +% \end{quote} +% +% \subsubsection{Functional shadings} +% +% By nature, the PostScript® code used to generate functional shadings must +% output either RGB or CMYK data. For this reason, +% \cs{pgfdeclarefunctionalshading} is \emph{not} portable across colour models. +% +% Take particular care that the same colour model is in use at declaration time +% and use time for functional shadings declared with an optional argument as +% otherwise the PostScript® data will not match the declared colour space and +% you will end up with a malformed PDF. +% +% This also means that you should \emph{not} use the functional shadings from +% the \pkg{tikz} shading library (|bilinear interpolation|, |color wheel|, +% |color wheel black center|, |color wheel white center|, and |Mandelbrot set|) +% except when the \pkg{xcolor} |rgb| colour model is in use, otherwise you will +% end up with a malformed PDF. +% +% Having said this, it \emph{is} possible to create portable functional shadings +% by providing conditional code to append colour transformations to the +% PostScript® data. A variety of \cs{pgffuncshading*to*} (e.g., +% \cs{pgffuncshadingrgbtocmyk}) macros along with \cs{ifpgfshadingmodel*} (e.g., +% \cs{ifpgfshadingmodelcmyk}) conditionals are provided to assist with these +% transformations. +% +% \begin{quote} +% \iffalse +%<*example> +% \fi +\begin{lstlisting} +\pgfdeclarefunctionalshading[black]{twospots} + {\pgfpointorigin}{\pgfpoint{3.5cm}{3.5cm}}{}{ + 2 copy + 45 sub dup mul exch + 40 sub dup mul 0.5 mul add sqrt + dup mul neg 1.0005 exch exp 1.0 exch sub + 3 1 roll + 70 sub dup mul .5 mul exch + 70 sub dup mul add sqrt + dup mul neg 1.002 exch exp 1.0 exch sub + 1.0 3 1 roll + \ifpgfshadingmodelcmyk + \pgffuncshadingrgbtocmyk + \fi + \ifpgfshadingmodelgray + \pgffuncshadingrgbtogray + \fi +} +\end{lstlisting} +% \iffalse +% +% \fi +% +% \pgfdeclarefunctionalshading[black]{twospots} +% {\pgfpointorigin}{\pgfpoint{3.5cm}{3.5cm}}{}{ +% 2 copy +% 45 sub dup mul exch +% 40 sub dup mul 0.5 mul add sqrt +% dup mul neg 1.0005 exch exp 1.0 exch sub +% 3 1 roll +% 70 sub dup mul .5 mul exch +% 70 sub dup mul add sqrt +% dup mul neg 1.002 exch exp 1.0 exch sub +% 1.0 3 1 roll +% \ifpgfshadingmodelcmyk +% \pgffuncshadingrgbtocmyk +% \fi +% \ifpgfshadingmodelgray +% \pgffuncshadingrgbtogray +% \fi +% } +% +% \begin{minipage}{0.3\linewidth} +% \pkg{xcolor} |cmyk| model:\medskip +% +% \selectcolormodel{cmyk} +% \pgfuseshading{twospots} +% \end{minipage}\hfill +% \begin{minipage}{0.3\linewidth} +% \pkg{xcolor} |rgb| model:\medskip +% +% \selectcolormodel{rgb} +% \pgfuseshading{twospots} +% \end{minipage}\hfill +% \begin{minipage}{0.3\linewidth} +% \pkg{xcolor} |gray| model:\medskip +% +% \selectcolormodel{gray} +% \pgfuseshading{twospots} +% \end{minipage} +% \end{quote} +% +% +% \subsection{Main Interface} +% +% \subsubsection{Declaring shadings} +% +% The four standard \pkg{pgf} functions for declaring shadings are supported +% as documented in the \pkg{pgf} manual. +% +% There is one extension provided by the \pkg{pgf-cmykshadings} package.
