+\section org_mitk_editors_mxnmultiwidget_F1Help General remark on F1 help
+ This is the help window of the MxN display. To display the help windows of other plugins, press F1 when the plugin of interest is active
+ (please make sure the tab of the plugin of interest is highlighted).
+ Alternatively, go to the <i>Help</i> menu and select <i>Open Help Perspective</i>. A help window opens from which you can select the documentation of the plugin of interest.
+
+\section org_mitk_editors_mxnmultiwidget_Overview Overview
+ The MxN display is an alternative image viewer to the Standard display.
+ It is a more flexible, customizable approach to displaying images with a strong focus on displaying different images
+ simultaneously but independently.
+ Unlike than the Standard Display it allows to show a different image for each window view while also allowing independent image navigation.
+ The number of window views can be freely chosen and anatomical view planes / view directions can be changed for each window view.
+
+\section org_mitk_editors_mxnmultiwidget_Working Working with the MxN display
+ The following sections describe how to work with the MxN display. The MxN display can be customized and several
+ properties can be set to modify the behavior.
+
+\subsection org_mitk_editors_mxnmultiwidget_Configuration Configuration Toolbar
+ The MxNDisplay is initialized with a single window view and a configuration toolbar on the right side.
+ In the toolbar you can find three icons / actions, where two buttons have an on/off state.
+ <table style="border: none;">
+ <tr><td>\imageMacro{QtWidgets/resource/mwLayout.png, "Layout button", 16.00}
+ <tr><td>\imageMacro{QtWidgets/resource/mwSynchronized.png, "Synchronize button", 16.00}
+ <td>\imageMacro{QtWidgets/resource/mwDesynchronized.png, "Desynchronize button", 16.00}
+ <tr><td>\imageMacro{QtWidgets/resource/mwMITK.png, "MITK mode button", 16.00}
+ <td>\imageMacro{QtWidgets/resource/mwPACS.png, "PACS mode button", 16.00}
+ </table>
+
+ <ul>
+ <li> Layout button: Choose a layout from presets or select a custom number of available window views and their layout in a grid
+ <li> Synchronization button: Enable or disable synchronized interaction across the window views
+ <li> Interaction mode button: Switch between the MITK interaction mouse mode and the PACS interation mouse mode
+ </ul>
+
+\subsubsection org_mitk_editors_mxnmultiwidget_Layout MxN display layout
+ There are several options to customize the MxN display layout.
+
+ Using the layout button from the configuration toolbar allows to customize the layout the following way:
+ <ul>
+ <li> By choosing the desired amount of windows and confirming via "Set multi widget layout". The window views are arranged in a rectangular grid, as specified.
+ Depending on the selected number of window views, existing window views will be removed or additional window views will be added.
+ New window views will have a sagittal view direction. Window views that stay untouched will keep their settings and continue displaying their selected data.
+ <li> By selecting one of the provided layout presets.
+ <li> By saving / loading a custom layout, either created using the previous methods and further refinement or by handcrafting a suitable file.
+ </ul>
+
+ \imageMacro{layoutWidget.png, "Layout widget" , 16.00}
+
+ By moving the cursor to the upper right corner of any window you can activate the window menu. It consists of three buttons:
+ <ul>
+ <li> The crosshair button allows to toggle the crosshair and to reset the view.
+ <li> The middle button expands the corresponding window to fullscreen.
+ <li> The right button allows you to choose between many different arrangements of the available windows.
+ </ul>
+
+ \imageMacro{layoutArrangements.png, "Layout arrangement", 16.00}
+
+\subsubsection org_mitk_editors_mxnmultiwidget_Synchronization Window synchronization
+ If data is displayed inside a window view you can interact with the window / loaded image using your mouse.
+ As long as the interaction synchronization is disabled (<img src="mwDesynchronized.png">), mouse interactions,
+ such as zooming, setting the point of interest, mouse wheel scrolling etc. will affect only the window view you click in.
+ If the interaction synchronization is enabled (<img src="mwSynchronized.png">), performing any of the mouse interactions inside a window view
+ will perform the same interaction in any other visible window view.
+
+\subsubsection org_mitk_editors_mxnmultiwidget_Interaction_Mode Mouse interaction mode
+ As mentioned before, you can use the mouse to interact with each window / loaded image.
+ There are two interaction modes which can be switched between using the interaction mode button:
+ the MITK interaction mouse mode and the PACS interaction mouse mode.
+ If the PACS interaction mouse mode is selected, an interaction tool bar is added to the left side of the
+ MxN display: It allows to select the action to perform for the left mouse button.
+ The difference between the MITK and PACS mode is as follows:
+
+ MITK interaction mouse mode <img src="mwMITK.png">
+ <ul>
+ <li> left mouse button: setting the point of interest
+ <li> right mouse button: zooming in and out while moving the mouse
+ <li> middle mouse button / pressing mouse wheel: moving the image while moving the mouse
+ <li> mouse wheel: scrolling through the displayed image slices
+ </ul>
+
+ PACS interaction mouse mode <img src="mwPACS.png">
+ <ul>
+ <li> left mouse button: depending on the selected mode in the interaction tool bar
+ <li> right mouse button: changing the level window for the topmost visible image under the mouse cursor
+ <li> middle mouse button / clicking mouse wheel: no interaction
+ <li> mouse wheel: scrolling through the displayed image slices
+ <li> strg-key + right mouse button: zooming in and out while moving the mouse
+ <li> shif-key + right mouse button: moving the image while moving the mouse
+ </ul>
+
+\subsection org_mitk_editors_mxnmultiwidget_Utility Utility Menu
+ Each window view has a utility menu at the top with four UI elements that allow to perform the following actions:
+ <ul>
+ <li> Data selection button: Select which data should be selected and visible inside the window view
+ <li> Lock / unlock button: Set the lock state of a window to couple / decouple the window from other windows.
+ <li> Slice slider: Navigate along the view direction of this window
+ <li> View direction drop down menu: Select the current anatomical view plane / view direction
+ </ul>
+
+ \imageMacro{utilityMenu.png, "Utility menu", 8.00}
+
+\subsubsection org_mitk_editors_mxnmultiwidget_Data_Selection Data node selection
+ Using the data selection button of a window view you can open a data node selection dialog which shows the currently
+ selected data nodes for the window view.
+ "Currently selected" means that you can either decide to show all available data nodes from the data storage
+ or - for a better data node overview - only show an individually selected subset of the available data nodes.
+ You can either remove a node from the selection by clicking the "x" on a data node or use the "Change selection"
+ button to individually select data nodes.
+ The "Select all nodes" checkbox denotes which of the selection types is currently used - showing all available data nodes
+ or showing only a subset of data nodes. Checking the checkbox will reset the selection to all available data nodes.
+
+ Selecting data nodes does not mean that this node always has to be visible in the window view (rendered). If you want to hide
+ a node, e.g. for temporarily inspecting underlying images, you can do so by clicking the "eye" icon for each selected data node.
+
+ If you want to reset the window view to a specific node / image, you can use the "arrow" icon. This will reset the camera to focus
+ on the selected node, using default zoom and centered camera position.
+ If you want so reset the camera to focus on the whole scene / all selected nodes, you can use the window menu, see
+ \ref org_mitk_editors_mxnmultiwidget_Layout.
+ Resetting a window only affects the corresponding window view, regardless of any synchronization / lock state.
+
+\subsubsection org_mitk_editors_mxnmultiwidget_Lock_Button Lock button
+ So far showing / hiding nodes or removing them from a selection / changing a selection affected all window views.
+ If you want to use individual selections for a window view, you can unlock / decouple the window view from other window views
+ by clicking on the lock button in the utility menu.
+ This will decouple the current window view. Changing the visibility of a node or selecting individual nodes / removing nodes
+ using the data node selection button will affect only the current window view.
+ This allows to show different images in each window view, e.g. by decoupling multiple window views and selecting individual nodes
+ in each window.
+ It is still possible to have a synchronized mouse interaction, see \ref org_mitk_editors_mxnmultiwidget_Synchronization and
+ \ref org_mitk_editors_mxnmultiwidget_Interaction_Mode.
+
+\subsubsection org_mitk_editors_mxnmultiwidget_Slice_Slider Slice selection slider
+ Displayed data is typically 3D data but each window view shows a 2D slice of the 3D volume. The direction in which the
+ 3D volume is sliced is defined by the "view direction" (or "anatomical plane").
+ To define at which position in the view direction the 3D volume should be sliced, the slice selection slider can be used.
+ It can either be moved using the mouse or by using the appropriate mouse interaction (see above, e.g. mouse wheel scroling).
+
+\subsubsection org_mitk_editors_mxnmultiwidget_View_Direction View direction
+ Each window view "is looking in" one of the three avaiable view directions, namely "Axial", "Sagittal" or "Coronal".
+ You can change the view direction by switching to another anatomical plane in the view direction drop down menu.
+ Changing the view direction will reset the camera to its default for the new view direction, meaning default zoom and
+ centered camera position.
