Superclass for algorithms that produce output of the same type as input.
Store vtkAlgorithm input/output information.
Abstract superclass for all arrays.
a vtkAbstractArray subclass for strings
dynamic, self-adjusting array of int

a simple class to control print indentation

vtkGetStringMacro(ExtensionsString)
Returns a string listing all available extensions.
represent text properties.
vtkSetMacro(IgnoreDriverBugs, bool)
When set known driver bugs are ignored during driver feature detection.
Interface for generating images and path data from string data, using multiple backends.
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
Store zero or more vtkInformation instances.
This filter takes an input dataset, an array to process (which must be a string array), and a text property.
