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.

SnapSliceOffsetToIJK()

void vtkMRMLSliceLogic::SnapSliceOffsetToIJK

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()

(

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.

UpdateFromMRMLScene()

virtual void vtkMRMLSliceLogic::UpdateFromMRMLScene ( )

protectedvirtual

Called everytime 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).
