Patent ID: 8098404

Claim:
A method for resizing a color digital uniform rosette halftone image composed of multiple colorant separations, the method comprising: receiving into a digital imaging system a digital uniform rosette halftone image and a desired resizing factor for the digital uniform rosette halftone image; defining uniform rosette cells within the digital uniform rosette halftone image; determining uniform rosette halftone screen parameters of the digital uniform rosette halftone image, the screen parameters defining uniform rosette Holladay halftone tiles within the digital uniform rosette halftone image; determining from the uniform rosette cells, a subset of uniform rosette halftone tile seams to delete, where the orientation of the seams is dictated by the received desired resizing factor; determining an energy for each of the uniform rosette halftone tile seams according to an energy metric so as to provide indication as to which seams have low energy; resizing the uniform rosette halftone image by manipulating low energy uniform rosette halftone tile seams to obtain a resized uniform rosette halftone image; and printing the resized uniform rosette halftone image on a printer.
