/**

|
* @class vtkLabelSizeCalculator
|
|
*
|
|
* This filter takes an input dataset, an array to process
|
|
* (which must be a string array), and a text property.
|
|
* It creates a new output array (named "LabelSize" by default) with
|
|
* 4 components per tuple that contain the width, height, horizontal
|
|
* offset, and descender height (in that order) of each string in
|
|
* the array.
|
|
*
|
|
* Use the inherited SelectInputArrayToProcess to indicate a string array.
|
|
* In no input array is specified, the first of the following that
|
|
* is a string array is used: point scalars, cell scalars, field scalars.
|
|
*
|
|
* The second input array to process is an array specifying the type of
|
|
* each label. Different label types may have different font properties.
|
|
* This array must be a vtkIntArray.
|
|
* Any type that does not map to a font property that was set will
|
|
* be set to the type 0's type property.
