baposter - 正确包含背景图像

我在用巴波斯特制作我的海报。

我正在尝试引入背景图像，我成功了，但总是收到“Overfull \hbox”警告，我无法调试。

我知道这个警告意味着什么以及如何克服它，但在这种特殊情况下我就是无法做到。

有问题的代码是我定义背景的地方（请注意，如果在下面指定“background=plain”，则警告会消失，因为不会显示背景）。

这是我的 MWE，你可以获取 baposter.cls这里

\documentclass[paperheight=36in,paperwidth=48in,fontscale=0.3]{baposter}

答案1

您在图片说明中输入了错误的空格。换行符就是空格。注释掉有问题的行尾即可解决问题。

离题：\sc早已弃用，不应使用。使用\scshape或\textsc{}。
