ABSTRACT:
A method and system to convert an electronic image file described in a page description language containing both contone and non-contone image objects to an intermediate binary format image. The intermediate format image separately encodes the contone and non-contone image objects. The contone image objects are edge-tagged. Prior to printing, the intermediate binary format page image is separated into the contone and non-contone image objects. The contone image objects are converted back to a contone form using the edge tagging to modify the filter weights of a digital filter. The non-contone image objects are converted to contone form by means of a pattern matching scheme.
