I am drawing arrows in a block diagram and using decorations.text to label them. Arrows going left to right are fine: the labels are upright. But arrows going right to left are appearing upside down.
For example:
\documentclass{article}
\usepackage{tikz}
\usepackage[graphics, active, tightpage]{preview}
\PreviewEnvironment{tikzpicture}
\usetikzlibrary{positioning, arrows.meta, bending, decorations.text}
\begin{document}
\begin{tikzpicture}
\node (aa) at (0,0) {A};
\node (bb) [right= 5cm of aa] {B};
\draw [-latex] [postaction={
decoration={text along path, text align=center, raise={1em},
text={Hello World}}, decorate
}]
(aa) to [bend right=45] (bb);
\draw [-latex] [postaction={
decoration={text along path, text align=center, raise={1em},
text={Goodbye World}}, decorate}]
(bb) to [bend right=45] (aa);
\end{tikzpicture}
\end{document}
How does one get "Goodbye World" to appear right side up? (I know I can use latex- to reverse the arrows, but in a complex drawing I'd prefer to draw the arrows the way flows actually happen in my model.)
