删除标题框的背景颜色

Question

欢迎来到 TeX.SE。

baposter.cls默认背景在类 ( ) 至shadeLR( )中设置background=shadeLR。此设置采用两种颜色：bgColorOne左侧为 (白色)，与bgColorTwo右侧的 (浅灰色) 混合。

要将相同的设置应用于，我们只需要复制在设置中posterbox适用的设置。background=shadeLRposterbox

因此，对于特定的海报盒环境，我们添加：

boxshade=shadelr,boxColorOne=white,boxColorTwo=lightgray

boxheader当我们headershape=rounded在环境中将设置为键时，会出现残留poster。可以通过添加headershape=rectangle以覆盖环境设置（headershape=rounded）或使用删除圆角来解决这个问题cornerradius=0em。

还要注意的是，这headerbox是一个宏，已被弃用。它的替代品是posterbox环境，我在这里使用了环境。一个关键的区别是posterbox环境可以接受使用verbatim环境的代码。

baposter.cls已经将颜色模型设置为CMYK并且编译pdflatex默认为utf8，因此\selectcolormodel{cmyk}和\usepackage[utf8]{inputenc}在这里是多余的。

\documentclass[a0paper,portrait]{baposter}

\usepackage{wrapfig}
\usepackage{lmodern}
%\usepackage[utf8]{inputenc} %unicode support
\usepackage[T1]{fontenc}
