tcolorbox 的内部渐变着色不起作用

我使用的是修改后的 IMSAloquium 模板。以下是我的代码

在框架标题框处，应该提供渐变颜色，正如手册中所说的那样，但事实并非如此。为什么？

答案1

添加tcolorbox选项enhanced。

摘自tcolorbox软件包手册 (v6.2.0, 2024-01-10)，第 10.1 节“样式选项键”(第 172 页)

如果→P. 157或→P. 158设置为、、或，则此选项 [ /tcb/interior style] 可用。不适用于。"/tcb/interior titled engine/tcb/interior enginepathpathfirstpathmiddlepathlaststandard

最初，/tcb/interior engine为standard。因此，要使其interior style有效，最低设置为interior engine=path。

方便的enhanced选项是 的简写，它将、所有绘图引擎（包括）skin=enhanced设置为，等等。/tcb/graphical environment=tikzpicture/tcb/interior enginepath
