Description

-----------

*Allows fast prototyping in Python for OpenCV*

Offers primitives and simplified interfaces to streamline prototypes construction in Python.

Facilitates:

* Windows construction and management

* Trackbar construction

* Configuration save/load (including trackbar values)

* Key binding (e.g. for trackbar control, configuration save/load)

* Video capturing and modification

* Work with images

* Work with text

* Frames transformation

Samples

-------

Color Palette

~~~~~~~~~~~~~

Let's replace 37 lines of source code from `Trackbar as the Color Palette `_

tutorial with ``ocvproto``-based implementation:

.. code-block:: python

    from ocvproto.toolbox import WindowManager, Canvas

    with WindowManager() as wm:

        rgb = wm.window.add_trackbar_group(['R', 'G', 'B'], max=255)

        for _ in wm.app.loop():

            wm.set_frame(Canvas(512, 300, color=rgb))

Camera capture

~~~~~~~~~~~~~~

Now let's capture video camera stream into ``ocvproto.avi`` file, being able to adjust blur.

Let's also setup config filepath (``ocvproto.json``) - this allows us to store current trackbar values

(``s`` key) and load them (``r`` key). It is useful to restore settings between sessions.

We bind ``z`` key to take camera shots.

.. code-block:: python

    from ocvproto.toolbox import WindowManager, Camera

    with WindowManager() as wm:

        wm.app.set_config('ocvproto.json')

        blur = wm.window.add_trackbar_group(['x', 'y'], 'Blur', default=1)

        with Camera() as cam:

            wm.app.bind_key('z', cam.dump_image)

            for _ in wm.app.loop():

                cam.read()

                cam.blur(blur)

                cam.dump()

                wm.set_frame(cam)
