DEVICE, METHOD, AND GRAPHICAL USER INTERFACE FOR EXTENDING FUNCTIONALITY OF A HOST APPLICATION TO ANOTHER APPLICATION

摘要

A host application executing on a client device includes a content processing extension that extends its functionality to process content items to a requesting host application executing on a client device. The content processing extension is an executable file that includes data conversion code and application code. The data conversion code, when executed in requesting host application, identifies content items provided by the requesting host application and formats the identified content items to be received by the content processing extension. The application code is native code executable by the host application associated with the content processing extension. The application code processes the results from execution of the data conversion and the identified content items in accordance with one or more functions of the host application, and returns the processed content items to the requesting host application via the content processing extension.
