Abstract: Example implementations relate to halftone image creation. An example non-transitory machine-readable medium can include instructions executable to determine a highlight core shape and a shadow core shape of a microcell within a supercell. The instructions can be executable to determine growth sequences for a plurality of pixels within the highlight core and the shadow core and between the microcell and other microcells within the supercell, divide each of the plurality of pixels into a plurality of subpixels, and create a halftone image for an unequal resolution printing device using a constrained direct binary search model and based on the highlight core shape, shadow core shape, growth sequences, and the plurality of subpixels.

Abstract: Strips of a page are processed according to a rendering technique, compressed, and stored in a memory buffer until a low memory condition of the buffer occurs. When the low memory condition occurs, the strips that are already stored in the buffer are decompressed, processed according to a memory utilization reduction technique, compressed, and stored in the memory buffer. Strips that are not yet already stored in the buffer when the low memory condition occurs are processed according to the rendering technique and then according to the memory utilization reduction technique before being compressed and stored in the memory buffer.
