TikZposter：如何将 tikzfigure 置于块内的中心

我注意到，所有包含\includegraphics语句的 tikzfigures（在 tikzposter 类中定义）都偏离了中心。如下面的第二个内部块所示（请原谅图片，graphicx演示选项在 tikzposter 下不起作用），图片在块内自动垂直居中（请注意顶部的较大空间）。无论我使用哪种块样式，都会发生这种情况。有人知道如何正确地垂直居中吗？（重新定义tikzfigure为垂直居中其内容会起作用，但仍然看起来很奇怪）

此外，在我的实际项目中，我使用了一个multicols包含不同大小图形的两列环境（参见第三个内块）。较大的图片在水平方向上略微偏离中心（这在我的实际项目中更为明显）。此外，较小的图片似乎总是位于顶部，而不是中心。我尝试了各种multicol相关选项来解决这个问题，但似乎都没有用。我不确定我的多列问题是否与我之前的问题有关，但希望是的。

偏心图片

欢迎来到 TeX.SE！根据这个很好的答案，最有效的方法可能是使用 minipages 这个非常古老的方法。

答案2

不是一个答案，而是在土拨鼠答案似乎是example-image-a稍微在左边， 稍微example-image-b在右边。
