/**
 * @class   vtkBlankStructuredGridWithImage
 * @brief   blank a structured grid with an image
 *
 * This filter can be used to set the blanking in a structured grid with
 * an image. The filter takes two inputs: the structured grid to blank,
 * and the image used to set the blanking. Make sure that the dimensions of
 * both the image and the structured grid are identical.
 *
 * Note that the image is interpreted as follows: zero values indicate that
 * the structured grid point is blanked; non-zero values indicate that the
 * structured grid point is visible. The blanking data must be unsigned char.
