Abstract:
1. A method for resizing a digital halftone image, the method comprising: receiving into a digital imaging system, a digital halftone image and a desired resizing factor for the digital halftone image; defining cells within the digital halftone image; determining from the defined cells, a number of halftone tile seams to manipulate, where the orientation of the number of halftone tile seams is dictated by the received desired resizing factor; determining an energy map of the digital halftone image according to an energy metric; determining the energy of the number of halftone tile seams within the energy map so as to provide indication of at least one low energy determined halftone tile seam; performing a resizing of the halftone image by manipulating the at least one low energy determined halftone tile seam, to obtain a resized halftone image; and, printing the resized halftone image on a printer.
