setState(state)

This method is called to set up the plugin when loading a session.

Note

This method is called only if the string returned by ORSServiceClass.OrsPlugin.orsPlugin.OrsPlugin.getState() at the saving of the session was not empty.

Parameters:state (str) – string of information as provided by the getState during the saving of the session

classmethod setWL2InView(datasetPresenter, view, min, max, logging=False)
interfacemethod skeletonize(listROIToModify)

Applies a skeletonize operation.

Deprecated since version 4.0: Use skeletonizeROI.

Parameters:listROIToModify (ORSModel.ors.ROI) [count=[1, None]] – ROI to modify
interfacemethod skeletonizeROI(aROI, IProgress=None)

Applies a skeletonize operation.

Parameters:
Const aROI:

True

Returns:

skeletonROI (ORSModel.ors.ROI) – the skeletonization of the ROI

skeletonizeROIAndPublish(aROI)
interfacemethod skeletonizeROIAsGraph(aROI, IProgress=None)

Applies a skeletonize operation and output the result as a graph.

Parameters:
Const aROI:

True

Returns:

skeletonGraph (ORSModel.ors.Graph) – the skeletonization of the ROI as a Graph

skeletonizeROIAsGraphAndPublish(aROI)
interfacemethod smooth(ROIToModify, kernelShape, kernelDim, kernelSize, allowNewVoxels=True, dataset=None, rangeMin=0.0, rangeMax=0.0, currentTime=0, IProgress=None)

Applies a smoothing operation on a ROI or a MultiROI.

Parameters:
  • ROIToModify (ORSModel.ors.ROI, ORSModel.ors.MultiROI) – ROI or MultiROI to smooth
  • kernelShape (str) – kernel shape (‘square’, ‘circle’ or ‘cross’)
  • kernelDim (int) – kernel dimension (2 or 3)
  • kernelSize (int) – kernel size (odd number between 3 and 33)
  • allowNewVoxels (bool) – if True, new voxels may be added by the smoothing operation; otherwise, the smoothing operation will only remove voxels.
  • dataset (ORSModel.ors.Channel) – dataset for range comparison (if application should be restricted to a range)
  • rangeMin (float) – minimal value of the range
  • rangeMax (float) – maximal value of the range
  • currentTime (int) – time step of the ROI
  • IProgress (ORSModel.ors.Progress) – progress object
Const dataset:

True

classmethod smoothMultipleROIs(listROIToModify, kernelShape, kernelDim, kernelSize, allowNewVoxels=True, dataset=None, rangeMin=0.0, rangeMax=0.0, currentTime=0)
interfacemethod splitAtOtsu(ROIToAnalyze, dataset, currentTime=0, IProgress=None)

Creates the ROIs of the background and foreground obtained by the Otsu’s method. The values taken in the histogram are those where in the dataset at the location in the ROI.

Parameters:
Const ROIToAnalyze:
 

True

Const dataset:

True

Returns:
  • ROIBackground (ORSModel.ors.ROI) – the locations of the ROI to analyze where the dataset has the values lower than the Otsu threshold
  • ROIForeground (ORSModel.ors.ROI) – the locations of the ROI to analyze where the dataset has the values higher than the Otsu threshold
  • isComputationCancelled (bool) – flag to know if the computation has been cancelled by the user
classmethod splitAtOtsuAndPublish(listROIToAnalyze, dataset, currentTime=0)
toggleRange()
toggleRangeAction()
interfacemethod undo(listROIToModify)

Undo the last operation made on a ROI or MultiROI.

Parameters:listROIToModify (ORSModel.ors.ROI, ORSModel.ors.MultiROI) [count=[1, None]] – ROI to modify
updateHistogramDataOfCurrentChannel()

Updates or creates an histogram data model object for the current range channel.

Return:
updateVisualUsedForRange()
