Ich kann die Farbverlaufsfarbe für die Kopfzeilenfarbe nicht erhalten Xbaposter, wenn ich sie mit Xelatex kompiliere, wird nur eine einfache Farbe angezeigt. Das Problem liegt in zwei Zeilen headerColorOne=black,und headerColorTwo=lightblue,bei der Definition der Farbe \definecolor{lightblue}{rgb}{0.145,0.6666,1}. Die CLS-Datei kann heruntergeladen werden vonCTANDie 3 Zeilen sind im MWE mit Problem gekennzeichnet:

Seit Version 3.1.3 tikzwerden nun CMYK-Schattierungen unterstützt, sodass das Laden nicht mehr erforderlich ist pgf-cmykshadings. (Der Fehler ist jedoch noch nicht behoben.)

Es gibt einen Konflikt zwischen dem pgfpagesPaket (geladen von [xe]baposter), dem pgfsys-dvipdfmxTreiber (verwendet von xelatex) und den Schattierungen. Ich weiß nicht genau, was los ist, aber das Endergebnis ist, dass Schattierungen nicht mit funktionieren xelatex. Ich habe einen Fehlerbericht eingereicht unterhttps://github.com/pgf-tikz/pgf/issues/520.

Wenn wir angeben, dass wir den Treiber möchten, funktioniert es trotzdem, pgfsys-dvipdfmallerdings kann dies andere Nebenwirkungen haben.

Außerdem haben Sie in Ihrem Poster-Setup eine headershade=plainOption, die die Schattierung in der Kopfzeile vollständig deaktiviert. Sie möchten diese Option also entfernen.

(xe)baposterUnd wie in den Kommentaren erwähnt , wird empfohlen, das Paket zu verwenden, wenn Sie Schattierungen verwenden möchten, pgf-cmykshadingsdamit Sie keine unerwarteten Farbabweichungen erhalten. In Ihrem speziellen Beispiel wird dies nicht passieren, aber es besteht immer die Möglichkeit. Dies liegt daran, dass alle Vollfarben in CMYK ausgegeben werden, alle Farbverläufe jedoch in RGB. Dies geschieht unabhängig davon, wie Sie Farben in Ihrem Dokument definieren. Wenn Sie in Ihrem Farbverlauf eine Farbe verwenden, die Sie auch anderswo als Vollfarbe verwenden, sehen sie anders aus. Vor diesem Hintergrund habe ich Ihre lightblueFarbe in CMYK neu definiert, damit sie auf dem Bildschirm ungefähr so ​​aussieht wie Ihre RGB-Definition.

Dies alles können Sie erreichen, indem Sie Folgendes vor Ihr setzen \documentclass:

\def\pgfsysdriver{pgfsys-dvipdfm.def}
\RequirePackage[cmyk]{xcolor}
\RequirePackage{pgf-cmykshadings}

Übrigens wäre es in Zukunft einfacher, wenn Sie Ihr Beispiel minimalistischer gestalten könnten. Das hilft uns, die Probleme schneller einzugrenzen.
