Abstract

Print objects (38) are captured. In the process of capturing each of the print objects (38) a user input gesture (34) over a region of a document (18) being rendered on a display (16) in accordance with a structured object specification (20) of the document (18) is received; an element of the structured object specification (20) being rendered within an active area of the user input gesture (34) on the display (16) is identified; the user input gesture (34) is interpreted as a print content designation command; and the print object (38) is derived from the structured object specification (20) in accordance with the identified element of the structured object specification (20) and the print content designation command. A print layout (32) of the print objects (38) on one or more pages (50) is determined. The print layout (32) is outputted.

9. The method of claim 8, wherein the hyperlink reference (64) points to a web page (98), and the generating comprises generating one or more of the print objects (38) by performing the receiving, identifying, interpreting, and deriving with respect to the web page (98).

10. The method of claim 8, wherein the hyperlink reference (26) points to a video file (102), and the generating comprises extracting one or more keyframes from the video file (102) and generating one or more of the print objects (38) from the extracted keyframes.

11. The method of claim 1, wherein the determining comprises automatically determining the print layout (32) by assigning respective ones of the print objects (38) to one or more pages (50) and determining a respective layout for each of the pages based on layout rules and layout optimization criteria applied to the print objects (38) assigned to the page (50).
