Class Code

class OrsPythonPlugins.OrsContourPath.OrsContourPath.OrsContourPath(*args, **kwargs)
cleanup()

Deletes the variables managed by the plugin. It is the place to remove callbacks and other references to Python objects that would prevent them to be garbage collected. This method is called during the process of deletion of the plugin. It calls for the cleanup and deletion of the forms.

interfacemethod editObjectFromGroupOfPaths(aGroupOfRegions: Group, operationToPerform: str, IProgress: Progress = None) → None

Edits an object from a set of regions using a Poisson reconstruction.

The regions used in the Poisson reconstruction are only the selected objects contained in the group.

Parameters:

  • aGroupOfRegions (ORSModel.ors.Group) – group containing a list of selected regions to use in the Poisson reconstruction. At this time, the only accepted regions are instances of VisualPath.

  • operationToPerform (str) – operation to perform Should be one of: [‘add’, ‘remove’, ‘intersect’, ‘replace’].

  • IProgress (ORSModel.ors.Progress) – progress object

interfacemethod generatePreview(inputDataset: Channel, viewName: str, useLevelling: bool, useGaussianFilter: bool, gaussianFilterStd: float, cannyProportion: float, cannySigma: float) → Channel

Generate a dataset of preview on the slice of the specified view

Parameters:

  • inputDataset (ORSModel.ors.Channel) – input dataset

  • viewName (str) – a view genealogical name

  • useLevelling (bool) – specifies if the window levelling should be used

  • useGaussianFilter (bool) – specifies if the Gaussian filter should be used

  • gaussianFilterStd (float) – standard deviation of the Gaussian filter

  • cannyProportion (float) – pondering factor (between 0.0 and 1.0) of the Canny filter to be added to the gaussian filtered result

  • cannySigma (float) – sigma parameter (>= 0) of the Canny filter

Returns:

previewDataset (ORSModel.ors.Channel) – the dataset of the preview

getCurrentPath()

the path object

Rtype:

ORSModel.ors.VisualPath

classmethod getMainFormClass()

Returns:

output –

interfacemethod getMeshFromGroupOfPaths(aGroupOfRegions: Group, meshTitle: str, meshColor: Color, IProgress: Progress = None) → Mesh

Creates a mesh from a set of regions using a Poisson reconstruction.

The regions used in the Poisson reconstruction are only the selected objects contained in the group.

Parameters:

  • aGroupOfRegions (ORSModel.ors.Group) – group containing a list of selected regions to use in the Poisson reconstruction. At this time, the only accepted regions are instances of VisualPath.

  • IProgress (ORSModel.ors.Progress) – progress object

Anonymize meshTitle:

True

Returns:

newMesh (ORSModel.ors.Mesh) – created mesh obtained by the Poisson reconstruction

interfacemethod getMeshPoissonReconstruction(aGroupOfRegions: Group, depth: int = 8, scale: float = 1.25, solverDivide: int = 8, isoDivide: int = 8, samplesPerNode: float = 1.0, normalsEvaluation: str = 'path plane', inputDataset: Channel = None, IProgress: Progress = None) → Mesh

Calls for a Poisson reconstruction on a set of regions.

The regions used in the Poisson reconstruction are only the selected objects contained in the group.

Deprecated since version 3.6: Use getMeshFromGroupOfPaths.

Parameters:

  • aGroupOfRegions (ORSModel.ors.Group) – group containing a list of selected regions to use in the Poisson reconstruction. At this time, the only accepted regions are instances of VisualPath.

  • solverDivide (int) – Poisson reconstruction parameter solverDivide

  • isoDivide (int) – Poisson reconstruction parameter isoDivide

  • samplesPerNode (float) – Poisson reconstruction parameter samplesPerNode

  • normalsEvaluation (str) – technique to evaluate the normals

  • inputDataset (ORSModel.ors.Channel) – dataset to be used if the normals are to be evaluated from a dataset

  • IProgress (ORSModel.ors.Progress) – progress object

Returns:

newMesh (ORSModel.ors.Mesh) – created mesh obtained by the Poisson reconstruction

classmethod getMinMaxValueLevelling(inputDataset, aView)

Gets the window levelling values for the given dataset in the given view, in data units.

Parameters:
