Abstract: Methods and apparatus for determining which displayed content, e.g., text, of a PDF document is selected and then taking an action based on the text selection, e.g., highlighting, coping, or editing the selected text. The methods and apparatus take into consideration potentially differences between text position and/or size differences between rendered and displayed page content and text position and/or size information obtained from performing a text extraction operation on the content of a PDF document. By combining extracted text information with post-render information corresponding to individual DOM elements in synthesized text elements and then storing the information in an easily access data structure, accurate identification of selected text characters can be made in a relatively fast manner using a browser implemented application.

Abstract: Methods and apparatus for managing resource utilization in a distributed system are described. Devices, e.g., servers, which use resources, e.g., processing cores, act as individual policy enforcement points. Individual servers retrieve and maintain local copies of resource lease records which are stored in a centralized data storage system. The individual server compares locally stored lease records to the retrieved lease records to check for any tampering in the centralized data storage and multiple states are supported to take into consideration transitory conditions and/or communications delays. Verification states include, e.g., a Pending Active state and a Pending Inactive State, in addition to an Active state and Inactive state, to delay licensing enforcement to account for centralized storage system eventual consistency delays.
