Create image data from a QImage.
Wrapper around std::string to keep symbols short.

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].
uses Qt to render the supplied text to an image.
Internals * Implementation
a simple class to control print indentation

Some derived classes for the different vectors commonly used.
