render the supplied text to an image.
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

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