vtkVector2i GetBounds(vtkTextProperty *property, const vtkStdString &string, int dpi) override
Given a text property and a string, get the bounding box [xmin, xmax] x [ymin, ymax].

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

Given a text property and a string, this function initializes the vtkImageData *data and renders it i...
