Abstract superclass for all arrays.
a simple class to control print indentation
Definition: vtkIndent.h:119
Store zero or more vtkInformation instances.
Store vtkAlgorithm input/output information.
dynamic, self-adjusting array of int
Definition: vtkIntArray.h:155
This filter takes an input dataset, an array to process (which must be a string array),...
int FillInputPortInformation(int port, vtkInformation *info) override
Fill the input port information objects for this algorithm.
~vtkLabelSizeCalculator() override
static vtkLabelSizeCalculator * New()
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
int RequestData(vtkInformation *request, vtkInformationVector **inInfo, vtkInformationVector *outInfo) override
This is called within ProcessRequest when a request asks the algorithm to do its work.
virtual void SetFontProperty(vtkTextProperty *fontProp, int type=0)
Get/Set the font used compute label sizes.
virtual vtkTextProperty * GetFontProperty(int type=0)
Get/Set the font used compute label sizes.
virtual vtkIntArray * LabelSizesForArray(vtkAbstractArray *labels, vtkIntArray *types)
virtual void SetFontUtil(vtkTextRenderer *fontProp)
Superclass for algorithms that produce output of the same type as input.
a vtkAbstractArray subclass for strings
represent text properties.
Interface for generating images and path data from string data, using multiple backends.
