Java OpenCV Loader
******************
.. highlight:: java
.. Class:: OpenCVLoader
Helper class provides common initialization methods for OpenCV library.
2012-06-21 22:50:05 +08:00
boolean initDebug()
-------------------
.. method:: static boolean initDebug()
2012-07-02 23:41:14 +08:00
Loads and initializes OpenCV library from within current application package. Roughly it is
analog of ``system.loadLibrary("opencv_java")``.
2012-06-21 22:50:05 +08:00
:rtype: boolean;
:return: returns true if initialization of OpenCV was successful.
2012-06-21 22:50:05 +08:00
.. note:: This method is deprecated for production code. It is designed for experimental and local
development purposes only. If you want to publish your app use approach with async
initialization.
2012-06-21 22:50:05 +08:00
boolean initAsync()
-------------------
.. method:: static boolean initAsync(String Version, Context AppContext, LoaderCallbackInterface Callback)
Loads and initializes OpenCV library using OpenCV Manager.
2012-06-21 22:50:05 +08:00
:param Version: OpenCV Library version.
:param AppContext: application context for connecting to the service.
:param Callback: object, that implements ``LoaderCallbackInterface`` for handling connection
status (see ``BaseLoaderCallback``).
:rtype: boolean;
:return: returns true if initialization of OpenCV starts successfully.
