Detailed Description

Slicer logic class for slice manipulation.

This class manages the logic associated with display of slice windows (but not the GUI). Features of the class include: – a back-to-front list of MrmlVolumes to be displayed – a compositing mode for each volume layer (opacity, outline, glyph, checkerboard, etc) – each layer is required to provide an RGBA image in the space defined by the vtkMRMLSliceNode

This class manages internal vtk pipelines that create an output vtkImageData which can be used by the vtkSlicerSliceGUI class to display the resulting composite image or it can be used as a texture map in a vtkSlicerView. This class can also be used for resampling volumes for further computation.

◆ SetName()

virtual void vtkMRMLSliceLogic::SetName ( const char *  )
virtual

Set / Get SliceLogic name.

◆ SetSliceCompositeNode()

void vtkMRMLSliceLogic::SetSliceCompositeNode ( vtkMRMLSliceCompositeNode SliceCompositeNode)

◆ SetSliceExtentsToSliceNode()

void vtkMRMLSliceLogic::SetSliceExtentsToSliceNode ( )


Set slice extents to all layers

◆ SetSliceNode()

void vtkMRMLSliceLogic::SetSliceNode ( vtkMRMLSliceNode newSliceNode)

◆ SetSliceOffset()

void vtkMRMLSliceLogic::SetSliceOffset ( double  offset)

◆ SetupCrosshairNode()

void vtkMRMLSliceLogic::SetupCrosshairNode ( )
protected

◆ SetWindowLevel()

void vtkMRMLSliceLogic::SetWindowLevel ( double  window,
double  level,
int  layer 
)
protected


Helper to set Window/Level in any layer

◆ SnapSliceOffsetToIJK()

void vtkMRMLSliceLogic::SnapSliceOffsetToIJK ( )

Set the current distance so that it corresponds to the closest center of a voxel in IJK space (integer value)

◆ StartSliceCompositeNodeInteraction()

void vtkMRMLSliceLogic::StartSliceCompositeNodeInteraction ( unsigned int  parameters)

Indicate an interaction with the slice composite node is beginning. The parameters of the slice node being manipulated are passed as a bitmask. See vtkMRMLSliceNode::InteractionFlagType.

◆ StartSliceNodeInteraction()

void vtkMRMLSliceLogic::StartSliceNodeInteraction ( unsigned int  parameters)

Indicate an interaction with the slice node is beginning. The parameters of the slice node being manipulated are passed as a bitmask. See vtkMRMLSliceNode::InteractionFlagType.

◆ StartSliceOffsetInteraction()

void vtkMRMLSliceLogic::StartSliceOffsetInteraction ( )

Indicate the slice offset value is starting to change.

◆ UpdateBlendLayers()

bool vtkMRMLSliceLogic::UpdateBlendLayers ( vtkImageBlend *  blend,
const std::deque< SliceLayerInfo > &  layers 
)
protected

Helper to update input of blend filter from a set of layers. It minimizes changes to the imaging pipeline (does not remove and re-add an input if it is not changed) because rebuilding of the pipeline is a relatively expensive operation.

◆ UpdateFromMRMLScene()

void vtkMRMLSliceLogic::UpdateFromMRMLScene ( )
overrideprotectedvirtual

Called every time the scene has been significantly changed. If the scene BatchProcessState events are observed (in SetMRMLSceneInternal() ), UpdateFromMRMLScene is called after each batch process (Close, Import, Restore...). It is also being called by default when a new scene is set (SetMRMLScene).

update the pipeline to reflect the current state of the nodes

◆ UpdateSliceCompositeNode()

void vtkMRMLSliceLogic::UpdateSliceCompositeNode ( )


Manage and synchronise the SliceCompositeNode
