摘要
As provided herein, there are supplied teachings to systems and methods for resizing a digital uniform rosette halftone image composed of multiple colorant separations, by using uniform rosette halftone tile parameters and iterative determination of energy metrics. One approach entails receiving into a digital imaging system, a digital uniform rosette halftone image and a desired resizing factor for that digital uniform rosette halftone image. Subsequently the system will define uniform rosette screen parameters to define uniform rosette Holladay halftone tiles within the color uniform rosette digital halftone image. From the defined uniform rosette cells, a number of uniform rosette halftone tile seams are determined for manipulation. The orientation of the number of uniform rosette halftone tile seams is dictated by the received desired resizing factor. The energy of the number of uniform rosette halftone tile seams is determined according to an energy metric so as to provide indication of low energy determined uniform rosette halftone tile seams. A resizing of the uniform rosette halftone image by iteratively deleting a number of the low energy determined uniform rosette halftone tile seam is performed so as to obtain a resized uniform rosette halftone image. The resized uniform rosette halftone image may then be printed on a printer.
