Usage
A superclass for reading netCDF files. Subclass add
conventions to the reader. This class just outputs data into
a multi block data set with a vtkImageData at each block. A
block is created for each variable except that variables
with matching dimensions will be placed in the same block.
To create an instance of class vtkNetCDFReader, simply
invoke its constructor as follows
obj = vtkNetCDFReader
Methods
The class vtkNetCDFReader has several methods that can be
used. They are listed below. Note that the documentation is
translated automatically from the VTK sources, and may not
be completely intelligible. When in doubt, consult the VTK
website. In the methods listed below, obj is an instance of
the vtkNetCDFReader class.
* string = obj.GetClassName ()
* int = obj.IsA (string name)
* vtkNetCDFReader = obj.NewInstance ()
* vtkNetCDFReader = obj.SafeDownCast (vtkObject o)
* obj.SetFileName (string filename)
* string = obj.GetFileName ()
* int = obj.UpdateMetaData () - Update the meta data from
the current file. Automatically called during the
RequestInformation pipeline update stage.
* int = obj.GetNumberOfVariableArrays () - Variable array
selection.
* string = obj.GetVariableArrayName (int idx) - Variable
array selection.
* int = obj.GetVariableArrayStatus (string name) - Variable
array selection.
* obj.SetVariableArrayStatus (string name, int status) -
Variable array selection.
* vtkStringArray = obj.GetVariableDimensions () - Returns an
array with string encodings for the dimensions used in
each of the variables. The indices in the returned array
correspond to those used in the GetVariableArrayName
method. Two arrays with the same dimensions will have the
same encoded string returned by this method.
* obj.SetDimensions (string dimensions) - Loads the grid
with the given dimensions. The dimensions are encoded in a
string that conforms to the same format as returned by
GetVariableDimensions and GetAllDimensions. This method is
really a convenience method for SetVariableArrayStatus. It
turns on all variables that have the given dimensions and
turns off all other variables.
* vtkStringArray = obj.GetAllDimensions () - Returns an
array with string encodings for the dimension combinations
used in the variables. The result is the same as
GetVariableDimensions except that each entry in the array
is unique (a set of dimensions is only given once even if
it occurs for multiple variables) and the order is
meaningless.
* int = obj.GetReplaceFillValueWithNan () - If on, any float
or double variable read that has a _FillValue attribute
will have that fill value replaced with a not-a-number
(NaN) value. The advantage of setting these to NaN values
is that, if implemented properly by the system and careful
math operations are used, they can implicitly be ignored
by calculations like finding the range of the values. That
said, this option should be used with caution as VTK does
not fully support NaN values and therefore odd
calculations may occur. By default this is off.
* obj.SetReplaceFillValueWithNan (int ) - If on, any float
or double variable read that has a _FillValue attribute
will have that fill value replaced with a not-a-number
(NaN) value. The advantage of setting these to NaN values
is that, if implemented properly by the system and careful
math operations are used, they can implicitly be ignored
by calculations like finding the range of the values. That
said, this option should be used with caution as VTK does
not fully support NaN values and therefore odd
calculations may occur. By default this is off.
* obj.ReplaceFillValueWithNanOn () - If on, any float or
double variable read that has a _FillValue attribute will
have that fill value replaced with a not-a-number (NaN)
value. The advantage of setting these to NaN values is
that, if implemented properly by the system and careful
math operations are used, they can implicitly be ignored
by calculations like finding the range of the values. That
said, this option should be used with caution as VTK does
not fully support NaN values and therefore odd
calculations may occur. By default this is off.
* obj.ReplaceFillValueWithNanOff () - If on, any float or
double variable read that has a _FillValue attribute will
have that fill value replaced with a not-a-number (NaN)
value. The advantage of setting these to NaN values is
that, if implemented properly by the system and careful
math operations are used, they can implicitly be ignored
by calculations like finding the range of the values. That
said, this option should be used with caution as VTK does
not fully support NaN values and therefore odd
calculations may occur. By default this is off.
