| Abstract: |
A method and apparatus for generating an illustration having the steps of inputting a plurality of strokes in an area having a designated dimension, assigning a texture and tone to the area, where the tone determines the nature and quantity of the plurality of strokes, generating the texture and the tone assigned in that portion of the illustration, and outputting the illustration.

First Claim:
Show all 38 claims |
We claim:
1. A method for using a computer to produce an image simulating a hand-drawn pen and ink illustration, comprising the steps of:
- (a) enabling a user to select an area comprising a portion of the image, said portion being less than the entire image;
- (b) enabling the user to specify one of a plurality of different stroke textures for the area in the image, said stroke textures comprising a plurality of simulated pen and ink strokes that convey a visual impression of both a tone and a texture, each of the plurality of stroke textures including random variations in the simulated pen and ink strokes to emulate corresponding hand-drawn strokes;
- (c) automatically applying the stroke texture specified by the user to the area in the image, the area limiting the extent of the stroke texture;
- (d) repeating steps (a) through (c) for each of a plurality of other areas in the image; and
- (e) rendering the image with the stroke textures specified for each of the areas by the user, to simulate a hand-drawn pen and ink illustration.
