发明名称 Method for smooth trapping suppression of small graphical objects using color interpolation
摘要 A method for smooth trapping of a small graphical object, includes receiving from a trap generator the location of a trap pixel in a small object that should be changed in color; determining the width of the small object containing the trap pixel; comparing the width of the thin object with a trap threshold width; if the width of the thin object is less than the trap threshold width, adjusting the hue of the trap pixel according to a predetermined relationship; and applying a trap correction to the trap pixel according to the adjusted trap hue. The predetermined relationship may be a linear relationship that interpolates the trap hue monotonically (from the original trap hue to the original object hue) for object widths less than the trap threshold width. The method may be applied to small objects and small font text objects.
