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 extracting information corresponding to a user selected area of a displayed web page are described. A user selected region, e.g., rectangular region, of a displayed web page is identified based on received user input. The elements beneath the user selected region are converted to a raster data URL. An HTML5 image element is created with an src attribute set to the raster data URL and with a low image element opacity property. The created HTML5 image element is added to the web page as an overlay. The web browser's built-in copying functionality can now be used to copy the overlying image element to the clipboard as an image as desired, e.g., using a context menu which enables image MIME type data to be placed on the clipboard.
