发明名称 Image manipulation
摘要 Image data is scaled, rotated and/or otherwise manipulated. Diffusive effects of associated interpolation and/or re-sampling are compensated for, or corrected, by applying an adaptive packing form of error diffusion to output data of one or more manipulating transforms. For example, rank order error diffusion is applied to output data of a manipulating transform, thereby restoring compaction to otherwise diffuse halftone structures (e.g., halftone dots, lines, etc), saturated text and/or other small, high contrast image elements.
