我正在使用该beamerposter.sty文件制作我的海报，并且我想在海报的标题部分放置一个背景 - 不是机构的图形或徽标，而是涵盖整个海报标题长度的实际背景。
我一直在搜索，但似乎找不到任何专门解决此问题的方法。我有 eso-pic、背景和壁纸包，所以如果您能提供其中任何一个的解决方案，我将不胜感激。以下是我想要实现的一个示例
这是我的海报的骨架

我无意使用提供的图片，但想法是相同的。
答案1
也许你会对这个解决方案感到满意。我只是修改了包中的标题定义confposter。我不知道如何确定标题的实际高度，因此需要手动调整背景图片的大小。此外，我不熟悉tikz包，我认为可能有更好的解决方案。我使用了“范围衰落“以改善海报文本的过渡。它有一个副作用：此选项会减少图片的宽度。因此，我添加了参数“比例=1.01“。”如图“是用于页眉背景的任意图片的名称。
