imshow

imshow(*im, ind=None, axis=None)[source]

Convenience wrapper for matplotlib’s imshow.

This automatically:
  • slices a 3D image in the middle of the last axis

  • uses a masked array to make 0’s white

  • sets the origin to ‘lower’ so bottom-left corner is [0, 0]

Parameters
  • im (ND-array) – The 2D or 3D image (or images) to show. If 2D then all other arguments are ignored.

  • ind (int) – The slice to show if im is 3D. If not given then the middle of the image is used.

  • axis (int) – The axis to show if im is 3D. If not given, then the last axis of the image is used, so an ‘lower’ slice is shown.

Note

im can also be a series of unnamed arguments, in which case all received images will be shown using subplot.
