base class for classes that render supplied text to an image.
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
virtual vtkVector2i GetBounds(vtkTextProperty *property, const vtkStdString &string, int dpi)=0
Given a text property and a string, get the bounding box [xmin, xmax] x [ymin, ymax].
a simple class to control print indentation

topologically and geometrically regular array of data

uses vtkTextRenderer to render the supplied text to an image.
Some derived classes for the different vectors commonly used.

represent text properties.

virtual void SetScaleToPowerOfTwo(bool scale)
Should we produce images at powers of 2, makes rendering on old OpenGL hardware easier.
