StaticImage

Description:

This example displays a 2D image in a non-interactable window. vtkImageCanvasSource2D is a source that starts as a blank image. User may add to the image with two-dimensional drawing routines. It can paint multi-spectral images. vtkImageViewer2 is a convenience class for displaying a 2D image
