Abstract
A method, apparatus, and information bearing medium for merging display items in encoded form involve providing display items to be merged in an encoded format, such as a run length encoded format (e.g., modified enhanced run length encoded format). The display items are examined on the basis of item priority. A target item having a target area is defined. The display items in the target area are merged according to item priority to produce the target item. The target item is representative of the merged display items. The encoded data associated with the display items to be merged includes control data and color data. In one embodiment, tokens are produced using the encoded data associated with the display items to be merged. The display items are merged using the tokens. The tokens represent counts of repeated data or pointers to pass-thru data associated with the display items to be merged.
