摘要： The present disclosure relates to a method and system for processing isolated dots of an image to be printed by a printer. The method includes detecting whether pixels corresponding to an isolated dot in the image are in an on state. A first sum of pixels that are in an on state in a first pixel ring surrounding the pixels corresponding to the isolated dot when the pixels in the isolated dot are detected to be in the on state is determined. The first sum of pixels in the first pixel ring that are in the on state is compared with a first threshold sum. A first number of pixels in at least a second pixel ring either comprising of or surrounding the pixels corresponding to the isolated dot are turned on when the first sum of pixels in the on state is less than the first threshold sum.

摘要： A method, system and data structure for providing a 3+1 layer MRC image, including a text layer. The text layer includes pixel data corresponding to text in an image and may be assigned a predetermined value for a particular color. According to one or more embodiments, the 3+1 layer MRC image may be subject to clean-up processing to alter one or more of the layers, other than the text layer, based on the text layer pixel data. This clean-up processing reduces redundant information stored in the 3+1 layer MRC image and provides opportunities for file size reduction (i.e., data compression).
