# scipy.misc.imsave

`scipy.misc.``imsave`(name, arr, format=None)

  Save an array as an image.

  Parameters: | name : str or file object Output file name or file object. arr : ndarray, MxN or MxNx3 or MxNx4 Array containing image values. If the shape is `MxN`, the array represents a grey-level image. Shape `MxNx3` stores the red, green and blue bands along the last dimension. An alpha layer may be included, specified as the last colour band of an `MxNx4` array. format : str Image format. If omitted, the format to use is determined from the file name extension. If a file object was used instead of a file name, this parameter should always be used.

  Examples

  Construct an array of gradient intensity values and save to file:

      >>> from scipy.misc import imsave
      >>> x = np.zeros((255, 255))
      >>> x = np.zeros((255, 255), dtype=np.uint8)
      >>> x[:] = np.arange(255)
      >>> imsave('gradient.png', x)

  Construct an array with three colour bands (R, G, B) and store to file:

      >>> rgb = np.zeros((255, 255, 3), dtype=np.uint8)
      >>> rgb[..., 0] = np.arange(255)
      >>> rgb[..., 1] = 55
      >>> rgb[..., 2] = 1 - np.arange(255)
      >>> imsave('rgb_gradient.png', rgb)
