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 a digital halftone image; defining cells within said digital halftone image; determining halftone screen parameters of said digital halftone image to define Holladay halftone tiles within said digital halftone image; determining, from said defined cells, a number of Holladay tile seams to delete, where an orientation of said number of seams is dictated by said received desired resizing factor; determining a seam energy of each of said determined number of seams, said seam energy being determined according to an energy metric so as to provide an indication as to which of said determined number of seams are low energy seams; iteratively deleting low energy seams to obtain a resized halftone image according to said resizing factor; and printing said resized halftone image on a printer.
