Abstract: A method of processing a page of a document. A plurality of commands describing graphical objects of the page configured to be reproduced in a first presentation mode are received, the plurality of commands indicating a type of each of the graphical objects, an enclosing region and a drawing order associated with each of the graphical objects. An object significance score is determined for each of the graphical objects using the respective object type and object depth. A significance profile for the page is determined by combining the determined object significance scores according to a page layout, the page layout being determined using the enclosing regions associated with the graphical objects. Logical structure elements of the page are determined using the significance profile. The plurality of commands are processed according to the determined logical structure elements for generating the page of the document in a second presentation mode.
