Allows one to view a 2D Numeric array as an image. This works best for very large arrays (like 1024x1024 arrays).
Function signatures:
imshow(2darray, ...)
Keyword arguments:
opacity: The overall opactiy of the vtk object. colormap: type of colormap to use. vmin: vmin is used to scale the colormap If None, the min of the data will be used color: the color of the vtk object. Overides the colormap, if any, when specified. extent: [xmin, xmax, ymin, ymax, zmin, zmax] Default is the x, y, z arrays extents. vmax: vmax is used to scale the colormap If None, the max of the data will be used representation: the representation type used for the surface. Must be 'surface' or 'wireframe' or 'points'. Default: surface transparent: make the opacity of the actor depend on the scalar. name: the name of the vtk object created.
Example:
def test_imshow(): return imshow(numpy.random.random((10,10)), colormap='gist_earth')
