Fehler beim Generieren von epub- und mobi-Formaten mit tex4ebook

Fehler beim Generieren von epub- und mobi-Formaten mit tex4ebook

Dies ist eine Fortsetzung meiner Fragen vonHierUndHier. Die Setup-Dateien wurden von @Michal.h21 bereitgestellt.

Ich erhalte Fehler, wenn ich tex4ebook verwende und EPUB- und MOBI-Ausgaben erzeuge.

Die Eingabedatei (sample.tex) ist:

\documentclass[ebook,12pt,oneside,openany]{memoir}

\newchessgame

This is a chessboard.

\mychessboard

\storebox{\mybox}{\mychessboard}

This is a chessboard from storebox.

Here comes a quotation \cite{Hiemenz}.

This is a chessboard from storebox.

Gibt es eine Möglichkeit, diese Fehler zu beheben, oder kann ich sie einfach ignorieren?

Danke schön.

Antwort1

Es gibt zwei Hauptursachen für die Probleme: Erstens chesboardverwendet das Paket Tikz, um Dinge auf das Schachbrett zu zeichnen, und erzeugt dadurch beschädigte SVG-Bilder. Das zweite Problem besteht darin, dass \usestorebox und wahrscheinlich auch in einigen anderen Konfigurationen falsche Absätze im HTML entstehen.

Es ist einfach, die SVG-Bilder zu deaktivieren. Wir müssen lediglich ein anderes Tikz-Backend verwenden, um Zeichnungen zu erstellen. Fügen Sie vor dem folgenden Code ein \usepackage{xskak}, der das Paket lädt chessboard:

\ifdefined\HCode
\def\pgfsysdriver{pgfsys-dvips.def}
\fi

Um die falschen Absatz-Tags zu behandeln, versuchen Sie diese geänderte .cfgDatei:

\RequirePackage{addfont4ht} % needed for skaknew font
%
% save the clearpage before it is redefined by tex4ht
%
\let\oldclrearpage\clearpage
%
% define macro for newpage insertion
%
\def\mypagebreak{\Configure{newpage}{\ifvmode\IgnorePar\fi\EndP\HCode{<div class="newpage"></div>}}}
%
% new chessboard command
%
\renewcommand\mychessboard[1][]{\ifvmode\IgnorePar\fi\EndP\HtmlParOff\HCode{<div class="chessboard">}\Picture*{}\chessboard[#1]\EndPicture\HCode{</div>}\HtmlParOn}
\let\tmpusavebox\usestorebox
\renewcommand\usestorebox[1]{\ifvmode\IgnorePar\fi\EndP\HtmlParOff\tmpusavebox{#1}\HtmlParOn\ifvmode\IgnorePar\fi\par\EndP\HCode{ }}

%

%

%

%
% modify \Configure{BODY} so our configurations work on all extracted pages
%
\Configure{@BODY}{\def\clearpage{\bgroup\mypagebreak\oldclrearpage\egroup}\HtmlParOn}
\Configure{@/BODY}{\global\let\clearpage\oldclrearpage\Configure{newpage}{}\HtmlParOff}
%
% skak fonts

\AddFontFace{SkakNewFigurine}{SkakNew-Figurine}{SkakNew-Figurine.woff}{}

%\Css{.SkakNew-Figurine-{font-family:"SkakNewFigurine",serif;}}
%
\begin{document}
%
\EndPreamble

Die Hauptunterschiede sind:

\renewcommand\mychessboard[1][]{\ifvmode\IgnorePar\fi\EndP\HtmlParOff\HCode{<div class="chessboard">}\Picture*{}\chessboard[#1]\EndPicture\HCode{</div>}\HtmlParOn}

Ich habe Befehle hinzugefügt, \HtmlParOffum \HtmlParOndie Einbeziehung jeglicher Absätze in das Schachbrett zu deaktivieren. Andernfalls würden Sie den folgenden ungültigen HTML-Code erhalten:

<!--l. 56--><p class="indent" >
<!--l. 58--><p class="indent" >   This is a chessboard from storebox.
</p>

   </p>

Wir müssen falsche </p>Tags auch nach Folgendem deaktivieren \usestorebox:

\let\tmpusavebox\usestorebox
\renewcommand\usestorebox[1]{\ifvmode\IgnorePar\fi\EndP\HtmlParOff\tmpusavebox{#1}\HtmlParOn\ifvmode\IgnorePar\fi\par\EndP\HCode{ }}

Der Wildcode am Ende: \HtmlParOn\ifvmode\IgnorePar\fi\par\EndP\HCode{ }fordert die Einfügung eines neuen Absatzes nach der gespeicherten Box. Mir ist klar, dass das ein bisschen kryptisch ist :)

\Configure{@BODY}{\def\clearpage{\bgroup\mypagebreak\oldclrearpage\egroup}\HtmlParOn}
\Configure{@/BODY}{\global\let\clearpage\oldclrearpage\Configure{newpage}{}\HtmlParOff}

</html>Dadurch wird die erneute Verwendung der Einbeziehung von Absätzen nach dem Tag deaktiviert \HtmlParOff.
