.. py:class:: magnum.trade.ImageData1D

    See `ImageData2D` for more information.

.. py:class:: magnum.trade.ImageData2D

    Similarly to `Image2D`, holds its own data buffer, thus doesn't have an
    equivalent to `ImageView2D.owner`. Implicitly convertible to `ImageView2D`
    / `MutableImageView2D`, so all APIs consuming image views work with this
    type as well.

.. py:class:: magnum.trade.ImageData3D

    See `ImageData2D` for more information.

.. py:class:: magnum.trade.ImporterManager
    :summary: Manager for `AbstractImporter` plugin instances

    Each plugin returned by `instantiate()` or `load_and_instantiate()`
    references its owning `ImporterManager` through `AbstractImporter.manager`,
    ensuring the manager is not deleted before the plugin instances are.

.. py:class:: magnum.trade.AbstractImporter

    Similarly to C++, importer plugins are loaded through `ImporterManager`:

    ..
        >>> from magnum import trade

    .. code:: py

        >>> manager = trade.ImporterManager()
        >>> importer = manager.load_and_instantiate('PngImporter')

    Unlike C++, errors in both API usage and file parsing are reported by
    raising an exception. See particular function documentation for detailed
    behavior.
