"""Image constructor.
The Image can be constructed by an existing Image, a QPixmap, a
QImage, loaded from a file path, or created empty.
To construct the Image by copying the data from the source,
pass the source as the first argument of the constructor.
``dest = Image(source)``
To create the Image by sharing the data of another Image, pass
the source Image as the data argument.
``dest = Image(data=sharedsource)``
The data argument can be a numpy array of 3 dimensions (w, h, c) which
will be used directly as the image's data, where w is the width, h is
the height, and c is the number of channels.
The data argument can also be a path to load.
To create an empty Image, leave path=None, and specify the width and
height. You can then optionally adjust the new Image's channels by
setting bitsPerPixel = 8, 16, 24, 32, or components = 1, 2, 3, 4,
which are equivalent to W (Grayscale), WA (Grayscale with Alpha),
RGB, and RGBA respectively.
