ABSTRACT:
The resolution of a dot image is converted by converting each input line of dots to a fixed number of output lines of dots. In each output line, different input dots give rise to different numbers of output dots. Within the fixed number of output lines generated from each input line, each input dot gives rise to different numbers of output dots in different output lines, but every input dot gives rise to the same total number of output dots.
