attachfile2: Setting icon colors does not work as expected

[osander1]

Consider the following test file:

\documentclass{article}
\usepackage[appearance=true]{attachfile2}

\begin{document}

\attachfile[color={0 0 1}]{some-document.tex}
\attachfile[color={1 0 0}]{some-document.tex}

\end{document}

This produces two blue pin icons, even though one of them should be red. It works correctly if I set appearance to false. My attachfile2 version is v2.8 from Debian testing.

attachfile2 reuses the appearance definitions. I'm not sure if there is a good way around this - it would blow up the pdf if every pin would have its own "appearance object". You can force a new object like this:

\documentclass{article}
\usepackage{xcolor}
\usepackage[appearance=true]{attachfile2}

\begin{document}

\attachfile[color={red}]{blub.tex}

\makeatletter \let\atfi@appobj@PushPin\undefined
\attachfile[color={blue}]{blub.tex}

\end{document}

Or you could define a number of variants like this:

\documentclass{article}
\usepackage{xcolor}
\usepackage[appearance=true]{attachfile2}
\makeatletter
\define@key{AtFi}{PushPinB}[]{%
  \def\atfi@icon{/Name/PushPin}%
  \def\atfi@icon@icon{PushPinB}%
}
\define@key{AtFi}{PushPinC}[]{%
  \def\atfi@icon{/Name/PushPin}%
  \def\atfi@icon@icon{PushPinC}%
}

\let\atfi@acroPushPinB\atfi@acroPushPin
\let\atfi@acroPushPinC\atfi@acroPushPin

\begin{document}

\attachfile[color={red}]{blub.tex}

\attachfile[color=blue,PushPinB]{blub.tex}

\attachfile[color=yellow,PushPinC]{blub.tex}

\attachfile[]{blub.tex}

\attachfile[PushPinB]{blub.tex}
\end{document}

Thinking about it, one could perhaps code the color in the internal function name.

Thanks for the reply. The workarounds are fine with me if you think that an actual fix would be too difficult / expensive. It would be great, however, if the documentation would mention that icon colors and appearance streams together don't work as expected.
