uses vtkTextRenderer to render the supplied text to an image.
static vtkTextRendererStringToImage * New()
void DeepCopy(vtkTextRendererStringToImage *utility)
Make a deep copy of the supplied utility class.
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 PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
void SetScaleToPowerOfTwo(bool scale) override
Should we produce images at powers of 2, makes rendering on old OpenGL hardware easier.
