\index{Mirror}
The Mirror plugin splits the image along a line, an axis, and reflects one side onto the other.
-When the \texttt{Enable Reflection Center} option is checked you can move the position of this axis, using $X\%$ and/or $Y\%$ slider and/or textbox:$X\%$ for the horizontal position and$Y\%$ for the vertical position. Mainly in the Mirror effect there are 2 cases: with or without the \textit{Enable Reflection Center} checked.

-When the \textit{Enable Reflection Center} option is UNCHECKED, the used reflection is on the center of the image (i.e. $X50\%$, $Y50\%$) and the options about \textit{Reflection Center}, $X\%$and $Y\%$, are disabled (grayed).
-The Horizontal option reflects the left side of the image on the right. If the \texttt{Swap LEFT-RIGHT} side option is checked then the right side to the left will be reflected.
+When the \textit{Enable Reflection Center} option is UNCHECKED, the used reflection is on the center of the image (i.e. $X=50\%$, $Y=50\%$) and the options about \textit{Reflection Center}, $X\%$ and $Y\%$, are disabled (grayed).
+The Horizontal option reflects the left side of the image on the right. If the \texttt{Swap LEFT-RIGHT side} option is checked then the right side to the left will be reflected.
The Vertical option reflects the top on the bottom. If the \texttt{Swap TOP-BOTTOM side} option is checked then the bottom to the top will be reflected.
There are special combinations when both Horizontal and Vertical checkboxes are enabled (and\textit{ Enable Reflection Center} is always UNchecked, of course). You can see those combinations in the figure~\ref{fig:mirror}.
-When the \textit{Enable Reflection Center} option is CHECKED the options about \textit{Reflection Center}, this is.$X\%$ and $Y\%$, are enabled, and the two \textit{Swap ... side} options are disabled and hidden. These two \textit{Swap ... side} are disabled because the$X\%$ and $Y\%$ allow the swap side feature automatically. The$X\%$ and $Y\%$ positions move the center of the reflection to fit to the User's need.
