Abstract
An image processing method and system compensates for artifacts in scaling operations of mixed raster content data representations. In such data representations, a document is segmented into data portions generally segregated by data types. At least one of the segments is dilated so that upon scaling reconstruction, there are additional pixels available for interpolation operations, thereby avoiding artifacts caused by discontinuity.
