摘要
A gradient-based trapping apparatus (100) includes a processing device (122) for receiving a current portion (116, 320) of a digital image (116, 320). If the current portion (116, 320) includes an edge (124, 312), a trapping device (122) produces a trapped portion (200, 320'). The trapped portion (200, 320') represents the current portion (116, 320) with varying colors. The trapping device (122) produces the trapped portion (200, 320') based on a plurality of patterns. Each of the patterns is chosen as a function of at least one of a) a distance of a current pixel within the current portion from the edge, b) at least one of a plurality of colors within the current portion, and c) a width of the trapped portion (200, 320').
