topologically and geometrically regular array of data
a simple class to control print indentation
Definition vtkIndent.h:40
Wrapper around std::string to keep symbols short.

Given a text property and a string, this function initializes the vtkImageData *data and renders it i...
virtual void SetScaleToPowerOfTwo(bool scale)
Should we produce images at powers of 2, makes rendering on old OpenGL hardware easier.
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].

Some derived classes for the different vectors commonly used.
