如何仅删除一个图像/单词的背景颜色？

Question

图像背后的背景颜色应为白色，覆盖整个框的高度。只有文本必须具有绿色背景颜色。是否可以在框内执行此操作，或者仅在另一个框中执行此操作以放置图像？

        This is an example of using the new \verb|aufgabe| environment with a subtitle.
        This should have the title appear as the \verb|new| environment.

使用

\newcommand{\dpcalc}{\rlap{\hspace{1em}\textbf{\inlinegraphics{example-image-b}\space}}}

我添加了一些\hspace你可以摆弄的东西。
