Swap Red and Blue Image Channels
================================


.. code-block:: default

    import numpy as np
    import imagepypelines as ip
    ip.require('image')
    ip.set_log_level('debug')









.. code-block:: default



    # swap red and blue color channels
    @ip.blockify()
    def swap_red_and_blue(image):
        return np.flip(image, axis=2)








Define our tasks and build the pipeline


.. code-block:: default


    tasks = {
            # set an entry point for images into the pipeline
            'images': ip.Input(),
            # swap channels
            'swapped': (swap_red_and_blue, 'images'),
            # Scale the images, cast dtype, and view the image comparisons!
            'safe': (ip.image.DisplaySafe(), 'swapped'),
            'null' : (ip.image.CompareView(pause_for=5000), 'images','safe')
             }

    swap = ip.Pipeline(tasks)








Let's process some data!
------------------------

Let's grab some example data from the ImagePypelines standard set


.. code-block:: default

    images = [ip.image.panda(), ip.image.gecko(), ip.image.redhat()]
    # Number and view the images!
    processed = swap.process(images)
