It divides the frame into two vertical and/or horizontal half-planes, allowing them to be translated and oriented to achieve complex reflections and compositions, which can be reminiscent of kaleidoscope. - -An example of horizontal + vertical reflection without Swap nor shifting of the center of reflection is shown in the figure~\ref{fig: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. \begin{figure}[htpb] \centering - \includegraphics[width=0.9\linewidth]{mirror.png} - \caption{mirror plugin} + \includegraphics[width=0.7\linewidth]{mirror.png} + \caption{Possible combinations with both Horizontal and Vertical checked} \label{fig:mirror} \end{figure} -\begin{description} - \item[Horizontal:] composes a reflection of the right half-plane joined to the left half-plane. The axis of reflection is central and vertical (Reflection Center). It can be used together with Vertical to have 4 half-planes of reflection. - \item[Swap LEFT-RIGHT side:] Swaps the two horizontal reflection half-planes, reversing their orientation. If this option is enabled, Enable Reflection Center is disabled. - \item[Vertical:] composes a reflection of the top half-plane joined to the bottom half-plane. The axis of reflection is central and horizontal (Reflection Center). It can be used together with Horizontal to have 4 half-planes of reflection. - \item[Swap TOP-BOTTOM side:] Swaps the two vertical reflection half-planes, reversing their orientation. If this option is enabled, Enable Reflection Center is disabled. - \item[Enable Reflection Center:] allows shifting the half-plane along the X-axis and/or along the Y-axis, relative to the Reflection Center. You can enter the percentage value or act on the slider for a visual adjustment. Checking this option excludes the use of swap functions. - \item[Reset] returns all values to the initial conditions, that is with only the Horizontal button enabled. -\end{description} +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. +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. \subsection{Motion51}% \label{sub:motion51}
