Claim Text:
1. A method comprising: obtaining, by a printing device, an a×b pixel macro-cell from an input image with one or more color planes, and an a×b attribute macro-cell, wherein the a×b pixel macro-cell contains 4 non-overlapping m×n pixel cells and the a×b attribute macro-cell contains 4 non-overlapping m×n attribute cells, wherein a×b pixels in the a×b pixel macro-cell are associated with respective color values, and wherein elements of the a×b attribute macro-cell are associated in a one-to-one fashion with respective pixels in the a×b pixel macro-cell; determining, by the printing device, 4 attribute-plane output values associated respectively with the 4 non-overlapping m×n attribute cells; determining, by the printing device, 1 to 4 color-plane output values for the non-overlapping m×n pixel cells; and writing, by the printing device, an interleaved representation of the 4 attribute-plane output values and the determined color-plane output values to a computer-readable output medium, wherein the interleaved representation is a compressed representation of the a×b pixel macro-cell and the a×b attribute macro-cell.
