paraview.simple.ExtractSubset¶

paraview.simple.ExtractSubset(*input, **params)¶

The Extract: Grid filter returns a subgrid of a structured input data set (uniform rectilinear, curvilinear, or nonuniform rectilinear). The output data set type of this filter is the same as the input type.

Data Descriptors¶

IncludeBoundary
If the value of this property is 1, then if the sample rate in any dimension is greater than 1, the boundary indices of the input dataset will be passed to the output even if the boundary extent is not an even multiple of the sample rate in a given dimension.

Input
This property specifies the input to the Extract Grid filter.

SampleRateI
This property indicates the sampling rate in the I dimension. A value greater than 1 results in subsampling; every nth index will be included in the output.

SampleRateJ
This property indicates the sampling rate in the J dimension. A value greater than 1 results in subsampling; every nth index will be included in the output.

SampleRateK
This property indicates the sampling rate in the K dimension. A value greater than 1 results in subsampling; every nth index will be included in the output.

VOI
This property specifies the minimum and maximum point indices along each of the I, J, and K axes; these values indicate the volume of interest (VOI). The output will have the (I,J,K) extent specified here.

Data Descriptors inherited from Proxy¶

__dict__
dictionary for instance variables (if defined)

__weakref__
list of weak references to the object (if defined)

Methods¶

Initialize = aInitialize(self, connection=None, update=True)

Methods inherited from SourceProxy¶

FileNameChanged(self)
Called when the filename of a source proxy is changed.

GetCellDataInformation(self)
Returns the associated cell data information.

GetDataInformation(self, idx=None)
This method returns a DataInformation wrapper around a vtkPVDataInformation

GetFieldDataInformation(self)
Returns the associated cell data information.

GetPointDataInformation(self)
Returns the associated point data information.

UpdatePipeline(self, time=None)
This method updates the server-side VTK pipeline and the associated data information. Make sure to update a source to validate the output meta-data.

UpdatePipelineInformation(self)
This method updates the meta-data of the server-side VTK pipeline and the associated information properties

__getitem__(self, idx)
Given a slice, int or string, returns the corresponding output port

Methods inherited from Proxy¶

GetProperty(self, name)
Given a property name, returns the property object.

GetPropertyValue(self, name)
Returns a scalar for properties with 1 elements, the property itself for vectors.

InitializeFromProxy(self, aProxy, update=True)
Constructor. Assigns proxy to self.SMProxy, updates the server object as well as register the proxy in _pyproxies dictionary.

ListProperties(self)
Returns a list of all property names on this proxy.

SetPropertyWithName(self, pname, arg)
Generic method for setting the value of a property.

__del__(self)
Destructor. Cleans up all observers as well as remove the proxy from the _pyproxies dictionary

__eq__(self, other)
Returns true if the underlying SMProxies are the same.

__getattr__(self, name)
With the exception of a few overloaded methods, returns the SMProxy method

__hash__(self)
Return hash(self).

__init__(self, **args)
Default constructor. It can be used to initialize properties by passing keyword arguments where the key is the name of the property. In addition registrationGroup and registrationName (optional) can be specified (as keyword arguments) to automatically register the proxy with the proxy manager.

__iter__(self)
Creates an iterator for the properties.

__ne__(self, other)
Returns false if the underlying SMProxies are the same.

__setattr__(self, name, value)
Implement setattr(self, name, value).

add_attribute(self, name, value)
