Abstract: Disclosed herein is a method that includes a classifier that distinguishes objects based on their color shades. A moving window based operator looks at the color class of the adjacent objects and determines if an adjustment is necessary. If at least one of the objects is the type of interest and the color classes of the objects meet the criteria, then the boundary between the objects is subject to be adjusted. Two adjustment modes are discussed: “adjust-tagging” mode and “adjust-color” mode. In the adjust-tagging mode, a specific tag is sent down to the print engine to force the use of high addressability halftones for the boundary pixels in the darker object. In the adjust-color mode, a color lighter (usually white) than that of the lighter object is assigned to the boundary pixels in the lighter object. The width of the modified pixels along the boundary is configurable.

Abstract: Sequential write operations to a unit of compressed memory, known as a compression tile, are examined to see if the same compression tile is being written. If the same compression tile is being written, the sequential write operations are coalesced into a single write operation and the entire compression tile is overwritten with the new data. Coalescing multiple write operations into a single write operation improves performance, because it avoids the read-modify-write operations that would otherwise be needed.

Abstract: The display color of, for example, a button image responsive to a command input into a facility operation display device is controlled by a palette value having a smaller number of bits than an RGB value. When the display color of the button image is changed, the palette value of a drawing object associated with the button image is changed to an RGB value. This eliminates the necessity of incorporating, for example, a high-performance CPU as a central arithmetic unit. In addition, it is not necessary to pre-store images corresponding to several kinds of display colors specified by RGB values, to thereby eliminates the necessity of incorporating, for example, a high-capacity storage medium in the facility operation display device. Accordingly, the device cost can be reduced.
