Input/Output with MahotasΒΆ

Mahotas does not have any builtin support for input/output. However, it wraps a few other libraries that do. The result is that you can do:

import mahotas as mh
image = mh.imread('file.png')
mh.imsave('copy.png', image)

It can use the following backends (it tries them in the following order):

  1. It prefers mahotas-imread, if it is available. Imread is a native C++ library which reads images into Numpy arrays. It supports PNG, JPEG, TIFF, WEBP, BMP, and a few TIFF-based microscopy formats (LSM and STK).
  2. It also looks for freeimage. Freeimage can read and write many formats. Unfortunately, it is harder to install and it is not as well-maintained as imread.
  3. Finally, it tries to load pillow.

Thus, to use the imread or imsave functions, you need to install one of the packages above. At one point, mahotas supported wrapping matplotlib, but their image loading methods are unreliable as it uses other packages itself. Thus, depending on what you had installed, the resulting images would be different.

If you are running on Windows, you may wish to try Christoph Gohlke’s packages.
